Glass fibers are widely used in reinforcement materials, insulation materials, building materials and other fields because of their advantages of light weight, high strength and corrosion resistance. However, glass fibers are easy to wear and break during the weaving process, which brings challenges to their practical production and application. Polyurethane can form a protective film on the surface of glass fiber due to its excellent elasticity, flexibility and wear resistance, which can improve its mechanical properties and wear resistance. The adhesion between glass fibers and polyurethane can be further improved by using suitable silane coupling agent. The interfacial bonding mechanism of anionic waterborne polyurethane (AWPU) and glass fibers (GFs) was investigated by molecular dynamics simulation and experimental verification. The effects of three common silane coupling agents on the interface bonding properties of polyurethane/glass fibers were studied, and the best sizing agent combination was selected to improve the overall properties of glass fibers. In this study, AWPU was selected as the sizing agent, and the molecular mechanism of AWPU/GF interface was analyzed by molecular dynamics simulation method. Three common silane coupling agents (KH550, KH560 and KH570) were selected to simulate their performance in interface bonding, and experiments were designed to verify the simulation results. In the experiment, the mechanical properties of glass fibers under different coupling agent combinations were tested, including breaking strength and wear resistance. The simulation results showed that the three silane coupling agents could improve the interface binding ability of polyurethane slurry on the glass fiber surface, and the average interface binding energy of AWPU/KH570/GF model was the highest ( 191. 488 kcal/mol). The experimental results are consistent with the simulation results, indicating that KH570 can improve the interface bonding property between polyurethane sizing agents and glass fibers to the greatest extent. In the single factor experiment, when the mass fraction of KH570 is 4%, the breaking strength and wear resistance of the sizing glass fiber are increased by 5.6% and 14.7%, respectively, compared with that without KH570, and the bunching performance is the best. It is found through molecular dynamics simulation and experimental verification that AWPU/KH570 is the best sizing agent combination. After further experimental optimization, the best sizing effect can be obtained when the mass fraction of AWPU and KH570 is 20% and 4%, respectively. In this study the effects of different silane coupling agents on the binding properties of PU/ glass fiber interface are investigated by molecular dynamics simulation and experimental verification for the first time and it is found that AWPU/ KH570 is the best sizing agent combination. This research method is not only fast and efficient but also reduces the waste of experimental materials which has high theoretical value and practical guiding significance. Future studies can further optimize molecular dynamics simulation parameters and explore more types of silane coupling agents and polyurethane combinations. At the same time it is necessary to expand the application range of the research results by combining with other high-performance fiber materials so as to provide theoretical support and technical guidance for the development of new high-performance fiber materials.

[Objective] To study the effects of different soil conditioners on the yield and quality of edamame in coastal saline-alkali soil. [Method] Five different conditioners were applied to the coastal saline-alkali land in Hangzhou Bay, Cixi, Ningbo. They were calcium ion exchange agents (T1), microbial algal fertilizer (T2), microbial fertilizer (T3), biochemical fulvic acid (T4), and mineral source potassium fulvic acid (T5). The effects of different treatments on the yield and quality of edamame were tracked and investigated. [Result] T, treatment significantly increased the yield of edamame in coastal saline-alkali soil, with 9 732. 4 kg/hm², a yield increase of 71.96 % over CK. The next two were T4 and T5, with significant differences in yield. Applying soil conditioner could increase the content of ascorbic acid and starch in edamame, but had no significant effect on the content of amino acids and crude protein. T, treatment and T, treatment significantly increased the ascorbic acid content of edamame, reaching 13. 55 and 11.69 µg/g. T3 treatment and T2 treatment significantly increased the starch content of edamame, reaching 26. 79 and 22. 11 mg/g respectively. [Conclusion] Applying soil conditioner can significantly increase the yield and improve the quality of edamame in coastal saline-alkali soil, which can provide certain guidance for improving the coastal saline-alkali soil to some extent.

In order to simulate the non-stationary typhoon wind field of overhead transmission lines, a simulation method for the non-stationary typhoon wind field of overhead transmission lines was proposed, taking into account the turbulence intensity and gust factor characteristics and their effects of the non-stationary pulsating wind field. Firstly, the Spline interpolation method was used to generate time-varying average wind speed, and the harmonic synthesis method of updating time-varying average wind speed was used to simulate fluctuating wind speed. Then, based on the three-dimensional wind spectrum power density function, the time-varying power spectrum of the typhoon wind field was constructed, taking into account the spatial correlation of the wind field, and the modulation evolution power spectrum was obtained, which is compared with the simulated typhoon power spectrum. Finally, taking the coastal 500 kV overhead transmission line as an example, the rationality of the typhoon simulation method was verified. The research results indicate that as the basic time interval increases, the proportion of non-stationary factors in typhoons increases. The non-stationary typhoon simulation method proposed can achieve the simulation of non-stationary typhoon wind fields on transmission lines. [ABSTRACT FROM AUTHOR]

At present, in the actual application conditions of the driven wheel hub bearing unit, there was a problem of frequent relative creep between the inner ring and the flange shaft.However, the anti-creep design of the inner ring lacked targeted theoretical research. To this end, an experimental study was carried out on the design of the inner ring to resist creep. Firstly, based on the force analysis and finite element software, the peripheral matching conditions and influencing factors of the inner ring and the flange shaft were analyzed.Then, based on the customized interference and locking force, static and dynamic dual creep tests between the inner ring and the flange shaft were carried out, and the friction coefficient of the end face was analyzed.Finally, through the inner ring static and dynamic creep tests, the interference between the inner ring and the flange shaft and the influence of the wheel hub bearing locking axial force on the creep was obtained.The result indicated that the interference design is 0.045 mm～0.060 mm between the inner ring and the flange shaft, and the locking with an axial force is not less than 100 kN, which can make the driven wheel hub bearing have excellent creep resistance, meet the requirements of no creep under the load condition of 0.7 g for passenger cars.

In order to master the dynamic response characteristics of transmission tower in mountainous area, taking the T-shaped transmission tower of 800kV UHV transmission line in mountainous area as the object, the finite element model of transmission tower rolling stone impact is established by using nonlinear explicit dynamic analysis software. The rod deformation, stress and time history change in the impact area of transmission tower are studied. The effects of rolling stone impact position, velocity, angle and mass on the impact response of transmission tower are analysed. The calculation formula of peak impact force of rolling stone of transmission tower is given and compared. The results show that the rolling stone impact force of transmission tower presents a triangular pulse shape, with short duration and large impact force; The deformation of auxiliary materials in the impact area of transmission tower is large, and the stress of its rod is the most unfavourable. During the impact, the stress level of the tower rod reaches the peak value instantaneously, then oscillates and decays rapidly, and gradually tends to be stable; After the impact of rolling stone, the tower pole will undergo plastic deformation, and the residual axial stress level of the tower pole is greater than the residual shear stress; When the impact position of the rolling stone is 1/6 to 1/8 tower height, the peak impact force of the rolling stone and the residual axial stress of the rod are relatively large. When the impact angle is 0 °, the impact response of transmission tower is the most severe. The impact velocity and rolling stone diameter have great influence on the impact response of transmission tower; The peak value fitting formula of impact force can be used to estimate the impact force of rolling stone of transmission tower.

In order to reduce effect of laser crystal heat yielded by the high power output of LD pumped full solid state laser,ANSYS finite element analysis software was used to analyze the nonlinear property of the thermal conductivity of the crystal with the temperature change. The Cr,Nd:GSGG crystal internal temperature field and thermal stress field distribution were obtained. The heat transfer coefficients of the cooling water and the crystal were simulated,as well as the temperature of cooling water. The temperature field distribution of the crystal after grinding the end surface,the stress distribution and deformation were obtained. The simulation results show that increasing heat transfer coefficients of cooling water and the crystal,or reducing the temperature of the cooling water can effectively reduce the temperature in the crystal rods,and the end face of the appropriate grinding also plays a role for the improvement of thermal lens effect.

Objective To investigate the predictive and diagnostic value of absolute value and function of different lymphocyte subsets in evaluating the risk of early viral infection after kidney transplantation. Methods Ninety-five kidney transplant recipients were enrolled in this prospective observational cohort study, and divided into the stable group (n=77) and infection group (n=18) according to postoperative immune status. Peripheral blood samples were collected for flow cytometry before operation, and 2 weeks, 1 month, 2 months and 6 months after operation. The dynamic changes of the absolute values of CD4+ T cells, CD8+ T cells and natural killer (NK) cells were compared between two groups. The function of lymphocyte subsets in two groups was evaluated by detecting the proportion of interferon (IFN)-γ+ CD4+ T cells, IFN-γ+ CD8+ T cells and IFN-γ+ NK cells. The value of the absolute values and function of lymphocyte subsets in predicting and diagnosing viral infection in the early stage after kidney transplantation was evaluated. Results During viral infection, the absolute values of CD4+ T cells, CD8+ T cells and NK cells in the infection group were at a relatively low level. At 2 months after operation, the absolute values of CD4+ T cells and NK cells in the infection group were lower than those in the stable group. At 6 months after operation, the absolute values of CD4+ T cells and CD8+ T cells in the infection group were significantly lower compared with those in the stable group (all P<0.05). During viral infection, the proportion of IFN-γ+ CD4+ T cells, IFN-γ+ CD8+ T cells and IFN-γ+ NK cells in the infection group were all at a relatively low level, especially that of IFN-γ+ CD8+ T cells decreased most significantly. At postoperative 2 months, the proportion of IFN-γ+ CD8+ T cells and IFN-γ+ NK cells in the infection group was significantly higher than those in the stable group. At 6 months after operation, the proportion of IFN-γ+ CD4+ T cells and IFN-γ+ CD8+ T cells in the infection group was significantly higher than those in the stable group (all P<0.05). Logistic regression analysis showed that the increasing proportion of IFN-γ+ CD8+ T cells and IFN-γ+ NK cells was correlated with the increasing risk of viral infection at 2 months after operation (both P<0.05). The receiver operating characteristic (ROC) curve demonstrated that the diagnostic value of absolute values of lymphocyte subsets combined with IFN-γ secretion function for viral infection in the immunocompromised recipients was significantly higher than that of absolute values of lymphocyte subsets alone (P<0.05). Conclusions Dynamic monitoring of the changes of absolute values and function of lymphocyte subsets provides critical reference value for the prediction, diagnosis and medication guidance of viral infection.
