    Henan Province is located in China's Central Plains region, is China's education province, basic education penetration rate. Under the guidance of the national macroeconomic policy, the idea of physical education is gradually expanded with the concept of 'health fi rst' and 'lifelong sports’. This paper selects eight high schools with typical and representative Nanyang as a research sample, this paper makes a deep research on the mental health of middle school students in Nanyang middle school physical education by using the method of literature, questionnaire survey and mathematical statistics.

    Benzoxazine resin, a new type of phenolic resin, has many advantages such as strong molecular design, no small molecular release in the curing process, excellent thermal stability and mechanical properties, and high residual carbon ratio. Thus, it is important for electronic communication industry matrix material. To meet the needs of highfrequency and high-speed communication technology for low-dielectric polymer resin, the low dielectric modifi cation of benzoxazine resin is of great signifi cance to the high frequency and high speed propagation of the signal, which causes a wide range of materials researcher’s attention. In this paper, we reviewed a series of studies on the low dielectric modifi cation of benzoxazine resin in recent years, including the synthesis of new monomers, inorganic - organic hybridization, copolymerization with other resins, and low molecular weight benzoxazine Resin research trends were outlined.

    The nonlinear asymmetric problem of McPherson suspension has become a challenging problem in the process of establishing the system model. This paper presents a planar 1/4-vehicle model that not only takes into account the vertical vibration of the sprung mass (chassis), but also includes: ix spring mass (wheel assembly) sliding and rotation; ii longitudinal wheel mass And its moment of inertia; iii tire damping and lateral defl ection. This dynamic kinematic model provides a solution to two important shortcomings of the traditional 1/4 vehicle model: it explains geometric modeling and tire modeling. This paper provides a systematic development of the planar model and a complete mathematical equation. This analysis model can be applied to hardware in the rapid calculation of ring applications. In addition, the model also gives a repeatable Simulink simulation implementation. The model has been compared with the actual Adams / View simulation to analyze the vibration and rebound motion of the wheel, as well as two related motion parameters: the dynamic characteristics of the camber and the pitch change.

    Insight - Sports Science, Vol.1, No.1, 2019; 620 Views, 16 PDF Downloads

    In this study, chemiluminescence immunoassay was used to screen clones of mouse anti-human albumin monoclonal antibody (anti-ALB McAb). The method is simplified as a one-step operation and the experimental parameters are optimized by orthogonal experiment [L9 (34)]. The parameters of the positive clone / blank control luminescence value (SNR) are the largest and the method is evaluated and statistical analysis. The results showed that the coated antibody was 3mg / L, the ratio of the enzyme protein A was 1: 2000, the incubation time was 304 times and the signal - to - noise ratio was 1284, which was several times higher than other combinations. The linear range was 20-20000ng / L, the precision was good, the average CV was 5.32% and the average inter-assay CV was 8.82%. The results showed that the method can be used for cloning and screening of anti-ALB McAb and the method is obviously superior to ELISA and other traditional methods, especially the simple and rapid operation of one step is also suitable for high antibody screening of other antibodies.
