篮球比赛进攻速度是进攻过程进行的快慢。获球方式是影响进攻的条件;技、战术水平是影响进攻的主要原因;进攻的结束方式对进攻速度没有影响。进攻的失误、违例、犯规使进攻成功率下降;造成对方防守犯规、投篮命中使进攻成功率上升。中国队进攻成功率低的主要原因是投篮命中率低和前场的失误、违例、犯规多造成的,而投篮命中率低则是因近投命中率低。随着进攻速度的由快到慢,进攻成功率呈逐渐下降的趋势,但在进攻成功率下降过程中,处在阵地进攻的范围,成功率有2次回升。

作者： Jiaming Yang and Xuejin YuDepartment of Applied Engineering nanchang institute of Aeroautical technology nanchang China (330034)

＜正＞In resent years, a lot of research works about geometrical nonlinear analysis of orthotropic plates have been made. Professor C.Y. Chia in Calgary University of Canada made systematic analysis about isotropic and orthotropic plates. At present, the most of study focus on four edges simply supported;four edges clamped;and the elastic rotation constrain boundary conditions of two opposite edges with the same support. But the study of nonlinear problem for three edges clamped and one edge simply supported is seldom reported. In the paper, the vibration functions of beam which can accurately meet the boundary conditions are presented. The functions with orthogonality advantage are fully used to transfer differential

关键词： three edges clamped and one edge simply supported orthotropic geometrical nonlinear algebraic equations

BIOLOGICAL effect of magnetic field is one of the three major subjects of contemporary biomagnetism, and is also the basis of applied biomagnetism. In order to explore magnetic biological effects, the influence of various sorts of magnetic field on many living systems as well as their different constructural levels has been extensively studied. However, only a few studies with in vitro enzyme have been reported, and few researches concerning the influence of magnetic field on immobilized enzyme reactions have been published. This note describes
