本文拟结合案例，对聚众斗殴罪的动机和目的、聚众斗殴行为、聚众斗殴罪中多次与持械的认定、聚众斗殴罪的转化犯，做一探讨。
P-D back-scattering cross sections and the multi-scattering of protons in solid;
P－D背散射截面及质子在固体中的多次散射
In this paper,multi-scattering of Rayleigh waves from the three-dimensional structures are investigated using the mode-coupling method.
这里采用模式耦合的方法,研究了均匀半空间和二层介质中(也可以是多层的),三维非均匀体对Rayleigh面波的多次散射,计算了频率和时间域中的散射波场,并分析了散射波场的特点,为散射面波的应用提供了初步的理论基础。
