Prestressed composite frame

The stress-bearing frame of the Aluminum extrusion machine body consists of an integral front beam ZG35Mn (thickness 1950mm) and a rear beam thickness 1800mm (materialZG35Mn), square prestressed sleeve (material ZG35) is a closed prestressed composite frame. Special hydraulic preloading tools are used to pull the An over-pressure tensile load is applied to the entire length of the rod, and compressive stress is applied to the pressure sleeve at the same time, so that the entire frame is in a stress pre-tightened state.The column prestress is above 115% of the maximum load.

(1) The center distance of the four stressed tie rods of the frame is symmetrical to the center of the press, so that the entire frame is stressed evenly. This can increase the squeeze

Accuracy of pressed products.

(2) Since the frame has a large bending resistance section, under the action of extrusion force, the frame elongation and bending deformation are small, so it is the frame can be fixed with horizontal and vertical guide rails at the bottom of the extrusion beam and extrusion barrel.

The centering adjustment is very convenient, and the upper frame can be used as an X-shaped moving guide rail for the extrusion barrel.

(3) There are two sets of elastic anchoring devices and foundation anchors at the lower part of the rear beam to make the rear beam fixed reliably.

Application of Plant Protection Drone in Corn Production

In the past, the traditional method of pesticide spraying was prone to various problems, such as missed spraying of pesticides, etc., resulting in poor control effects on corn pests and diseases. The application of plant protection drones can effectively solve these problems. Based on the needs of corn production, coupled with the continuous improvement of the level of science and technology, plant protection drones can provide good protection for plant protection in corn production, and achieve high-quality and high-yield corn.

Application Significance of Plant Protection Drone in Corn Production

In corn production, the application of plant protection drones can not only enhance the efficiency of pesticide operations, but also improve the safety of pesticide spraying. It can also reduce operating costs to a certain extent and play a significant role in pest control. For plant protection drones, it has the advantage of fast flight speed. On this basis, chemical spraying can effectively improve the operation efficiency [1]. At the same time, compared with manual work, the use of plant protection drones can greatly reduce the contact between personnel and chemicals, thereby enhancing safety. The use of plant protection drones can combine the actual situation, choose functions such as hovering in the air, and effectively spray chemicals, and can carry out low-altitude operations to exert a good control effect.

Application suggestion of plant protection Drone in corn production

2.1 Increase government support

At present, the advantages of plant protection drones are becoming more and more prominent. The application of plant protection drones is helpful for pest control. In order to better develop plant protection UAVs and adapt to future development trends, relevant departments need to give full play to their roles, combine the actual situation, provide policy subsidies, and devote themselves to the wide application of plant protection UAVs. This can reduce the economic burden of farmers to a certain extent and improve the enthusiasm of farmers to purchase.

2.2 Strengthen technical training

As a high-tech product, relevant personnel need to have sufficient technical knowledge and corresponding operating skills to be able to play a better role and improve the application effect. Therefore, technical training is very necessary. During the training process, it is necessary to focus on explaining the technical principles of plant protection drones, and to fully demonstrate its actual structure. More importantly, it is necessary to conduct practical training for relevant operators to promote scientific and rational use of plant protection drones. For pesticide spraying, ensure that the amount of spraying is moderate. At the same time, through training, we can better discover the problems of plant protection drones, and take measures as soon as possible when problems occur. Before use, it is necessary to consciously check to ensure the comprehensiveness of the inspection and provide a good guarantee for the safe operation of plant protection drones [2].

2.3 In-depth technical research

At present, plant protection drones are widely recognized and concerned, and have become a hot spot in industry investment. Many companies in China are committed to the research and development of plant protection drones. Through continuous increase in research and development, the rapid development of plant protection drones is promoted. Among them, it is necessary to focus on the research on the pharmaceutical effects of plant protection drones, and continue to develop new functions to achieve the safe development of the corn industry. At the same time, more attention needs to be paid to the battery capacity of plant protection drones. Through effective research and development, the battery capacity will be continuously increased to promote a significant improvement in battery life.

2.4 Operation points of plant protection Drone

To carry out plant protection drone operations, it is necessary to strictly follow the relevant operating procedures, abide by the relevant operating requirements, and ensure the standardization of operations, so as to effectively ensure safe operations. Specifically, all aspects and multi-angle inspections are required before and after the use of plant protection drones. In the actual inspection process, it is necessary to follow a certain order to ensure that no omissions are left. After the inspection is correct, the plant protection drone can be started. After the work is completed, the relevant personnel need to clean it comprehensively. Not only the fuselage, but also the rotor and the landing gear need to be cleaned. At the same time, it is necessary to focus on the spraying system and clean it effectively. While cleaning, it is necessary to start the inspection procedure, among which, it is necessary to focus on the inspection of the fuselage of the plant protection drone to check whether there are obvious cracks. At the same time, it is necessary to check the main components and pay attention to the firmness of the screws. Once a problem is found, it is necessary to contact the manufacturer as soon as possible and take appropriate measures to solve and deal with it.

When conducting flight operations, it is necessary to control the flying height of the plant protection drone in combination with the actual situation, and ensure that there is no leakage of spraying, and at the same time prevent the occurrence of heavy spraying and other situations. For the actual flight operation speed, scientific and reasonable control is also required. For the actual flight operation distance, it needs to be determined in advance, based on the size of the field, to effectively complete the flight operation and avoid temporary round trips. In order to ensure the safety of flight operations, it is necessary to stay away from crowds and high-voltage lines during the actual operation of eavisionag plant protection drones. Check the battery of the plant protection drone to ensure that the power is sufficient, and pay attention to testing the walkie-talkie to ensure that the signal is good. When the weather is relatively bad, such as rainy days, etc., it is not possible to carry out plant protection drone operations.

EPR (Electron Paramagnetic Resonance) Spectroscopy, also known as Electron Spin Resonance (ESR) Spectroscopy, is a technique used to study the electronic structure of paramagnetic species.

There are two main types of EPR spectroscopy: Continuous Wave (CW) EPR spectroscopy and Pulsed EPR spectroscopy.

Continuous wave (CW) EPR Spectroscopy:

In continuous wave EPR spectroscopy, a microwave source continuously emits microwave radiation at a fixed frequency into the sample.

A magnetic field is swept over a range of frequencies and the absorption of the microwave radiation by the sample is measured as a function of the magnetic field strength. This produces an EPR spectrum showing the jumps between energy levels of paramagnetic species.

CW EPR spectroscopy is commonly used to study relatively slow dynamic processes and to examine stable paramagnetic species.

Pulsed EPR Spectroscopy:

Pulsed EPR spectroscopy, also known as pulsed electron-electron double resonance (ELDOR) or electron-electron resonance, utilizes short pulses of electromagnetic radiation. This technique is used to study the dynamics of paramagnetic species and their interactions with their surroundings.

Pulsed EPR spectroscopy provides more detailed information and allows the measurement of relaxation times, distances, and other dynamic parameters. It involves applying microwave pulses, often combined with radio frequency (RF) pulses, to manipulate the electron spin state and measure the resulting signal.

Pulsed EPR techniques include Electron Spin Echo (ESE), Electron Nuclear Dual Resonance (ENDOR), Electron Spin Echo Envelope Modulation (ESEEM), and others.

Pulsed EPR spectroscopy is particularly well suited for the study of transient species, radical reactions, and spin-spin interactions in paramagnetic systems.

Both CW EPR and pulsed EPR spectroscopy have their advantages and applications, depending on the specific research objectives and the properties of the paramagnetic species under study.

The Scanning Electron Microscope (SEM) is a powerful tool for various applications in material sciences, life sciences, and other fields. Different kinds of detectors have been developed to obtain more information and improve the performance of SEM. The following are a few common types of SEM detectors:

Backscattered Electron Detector (BSE): BSE detectors are used to detect electrons scattered by the nuclei of atoms and high atomic number elements within a substance.BSE detectors provide high-contrast images that can be used for compositional analysis of materials and characterization of microstructures.

Secondary Electron Detector (SE): The SE detector is used to detect secondary electrons on the surface of a material excited by a scanning electron beam. Since the surface morphology and material composition influence the secondary electrons, the SE detector provides a high-resolution image of the surface topography.

Transmission Electron Detector (TED): TED detectors are used to detect transmission electrons that pass through a thin sheet of material and are focused on the detector. TED detectors are suitable for high-resolution compositional and structural analyses of materials, e.g., atomic-level characterization of nanoparticles.

Energy Dispersive X-ray Spectroscopy (EDS): EDS detectors are used to analyze the elemental composition of materials. When a scanning electron beam interacts with a sample, characteristic X-rays are produced, and the EDS detector collects and measures the energy spectrum of these X-rays to determine the chemical composition and elemental distribution of the material.

Retarding Field Detector (RFD): The RFD detector is used to measure the charge carried by electrons generated on the surface of the sample. This type of detector is very useful for studying the electrical conductivity and surface charge properties of materials.

These are just some of the common SEM detectors; in fact, there are many other types of detectors, each with different advantages and applications. The selection of the appropriate detector depends on the objectives of the study and the information to be obtained.

CIQTEK's self-developed SEM offers a wide range of detectors to choose from, such as BSED, STEM, EDS, EDX, EBSD, In-lens, ETD, etc. 

ESR (Electron Spin Resonance) and EPR (Electron Paramagnetic Resonance) are used interchangeably to describe the same spectroscopic technique. The reason for the two different names can be traced to the historical development of the field and some of the interesting stories surrounding it.

Originally, the technique was called ESR, or electron spin resonance. It was discovered in the mid-20th century by physicists studying the behavior of electrons in magnetic fields. They observed that certain materials absorbed energy at specific frequencies when exposed to strong magnetic fields and subjected to electromagnetic radiation. This absorption is due to the electron spin states flipping in the magnetic field, resulting in resonance.

As the field grew, researchers began to study the spectra of paramagnetic species - atoms, molecules, or ions with unpaired electrons. They realized that ESR techniques could be used to study a wider range of systems than just electrons. As a result, the term EPR (Electron Paramagnetic Resonance) was coined to encompass a broader range of applications.

The transition from ESR to EPR did not happen overnight or with universal adoption. Different research groups and scientific communities preferred to use either term. For example, the term ESR was widely used in the United States, while EPR became popular in Europe. This difference in naming conventions continued for some time until the two terms gradually became synonymous. Today, the two terms are widely accepted and used interchangeably to describe the same spectroscopic techniques.

The dual naming of ESR and EPR provides insight into the historical development of the field and how scientific terminology has evolved and adapted over time. It also serves as a reminder that in science, different cultures and communities may adopt different names for the same concept, and these differences may persist until a consensus is reached.

EPR spectroscopy has applications in a variety of fields including chemistry, physics, biochemistry, materials science, and medicine. It has been used to study the structure of metalloproteins, the mechanism of enzyme reactions, the properties of organic radicals, the behavior of transition metal complexes, and defects in semiconductors, as well as many other fascinating areas of research. Its ability to probe electron spin makes it an invaluable tool for understanding the fundamental properties of paramagnetic systems and exploring their role in a variety of physical and chemical processes.

Electron paramagnetic resonance (EPR) spectroscopy is a powerful technique used to study the electronic structure of paramagnetic substances. It provides valuable insights into the nature and interactions of unpaired electrons in magnetic fields. Selection rules in EPR spectroscopy establish conditions that allow or prohibit leaps between different energy levels. Understanding these selection rules is essential for data interpretation and extracting meaningful information from EPR spectra.

Rotational selection rules in EPR

The most basic EPR spectroscopy selection rule is the spin selection rule. It states that for an electron jump to occur, the spin projection quantum number (m_s) must change by ±1. The m_s value describes the orientation of the electron spin for an external magnetic field. This shift can be caused by a spin flip (parallel to antiparallel or vice versa) or spin conservation (parallel to parallel or antiparallel to antiparallel).

Magnetic quantum number selection rules in EPR

The magnetic quantum number (m_l) selection rule is also important in EPR spectroscopy. It states that the change in m_l value due to transitions must be ±1. The m_l value is related to the component of angular momentum of the electron along the magnetic field axis. EPR leaps usually involve a change in the angular momentum of the electron orbitals, which results in a change in the m_l value.

Transition selection rules in EPR

Another important selection rule in EPR spectroscopy is the transition selection rule. It states that only allowed leaps will be observed in the EPR spectrum according to the spin and magnetic quantum number selection rules. No forbidden transitions that violate the selection rule will be detected. This rule facilitates the interpretation and assignment of spectral features.

Forbidden transitions in EPR

Although forbidden leaps strictly violate the selection rule, they sometimes occur with very low probability. Forbidden leaps are usually caused by weak interactions, such as spin-orbit coupling, which couples spin and orbital angular momentum. These leaps are usually observed as weaker spectral features compared to the allowed leaps.

Thus, selection rules play a key role in EPR spectroscopy, controlling the transitions between the energy levels of paramagnetic matter. Spin selection rules, magnetic quantum number selection rules, and lepton selection rules identify allowed and forbidden leaps that enable the interpretation and analysis of EPR spectra. Understanding these selection rules helps researchers extract valuable information about the electronic structure, spin dynamics, and magnetic properties of paramagnetic systems when using EPR spectroscopy.

The g-value plays a crucial role in EPR (Electron Paramagnetic Resonance) spectroscopy in understanding the electronic structure and magnetic properties of paramagnetic substances. Today, we will talk about the key factor in EPR spectroscopy: the g-value (g-factor).

The g-value is a dimensionless quantity that represents a constant of proportionality between the magnetic field and the energy difference between the energy levels in the system. The g-value can be obtained by measuring the resonance frequency of a paramagnetic substance absorbing electromagnetic radiation in the presence of a magnetic field. It represents the extent to which the electron spin interacts with the external magnetic field. The g value is commonly used to determine important characteristics of paramagnetic substances, such as the number of unpaired electrons and their orbital angular momentum.

For a free electron, the g value is a constant of 2.0023, derived from fundamental physical properties. However, in more complex systems, such as transition metal complexes or organic radicals, the g value can deviate from this standard value. The deviation arises due to various factors, including spin-orbit coupling and hyperfine interactions with nearby nuclei. These interactions introduce additional energy levels and modify the electron's behavior in the magnetic field, leading to different g values.

By analyzing the g value in EPR spectroscopy, scientists can gain insights into the molecular structure and chemical environment of the paramagnetic species under investigation. A change in the g value can reveal the presence of different ligands or coordination environments around a metal ion, providing valuable information about the electronic configuration and coordination chemistry.

In addition, the g-value can be used to study the dynamics of a system. For example, it can provide information about the rate of electron transfer or spin relaxation processes, revealing the kinetics and mechanisms involved in chemical reactions or biological processes.

A common method of measuring the g-value is using EPR spectroscopy on a sample with a known g-value. This reference sample can be a compound with a well-characterized g-value or a spin probe, such as a stable organic radical. By comparing the position and shape of the resonance signals of the reference sample and the sample of interest, the g-value of the unknown species can be calculated.

Another approach involves calculating the g value from the Zeeman effect. The Zeeman effect describes the splitting of energy levels in a magnetic field. By measuring the magnetic field strength required to observe resonance at different frequencies, the g value can be derived using the equation g = hν/μBΔB, where h is Planck's constant, ν is the microwave frequency, μB is the Bohr magneton, and ΔB is the magnetic field difference between the resonance peaks.

In addition, the g value can be determined by analyzing the linewidth of the EPR signal. Since the g value depends on the orientation of the unpaired electrons in the magnetic field, any interaction or fluctuation in the environment will broaden the EPR signal. The g-value can be estimated by measuring the linewidth and analyzing its dependence on the magnetic field strength.

It is worth noting that the g value is not always a fixed constant. In some cases, it may vary due to factors such as electron-electron interactions or electrons leaving the domain. These variations can indicate the chemical or physical properties of the paramagnetic substance.

In summary, the g-value in EPR spectroscopy is an important parameter that helps characterize paramagnetic substances. By determining the g-value, researchers can gain valuable insights into the electronic structure and properties of paramagnetic compounds, contributing to understanding a wide range of scientific disciplines, including chemistry, physics, and biology.
