简介：波浪光线理论被采用与不对称的基本流动在台风学习旋涡Rossby波浪的繁殖小径(光线)的特征，在正切的不对称的基本流动被在对称的基本流动上附加wavenumber-1不安流动构造的地方，并且光线的基本流动从非分叉方程被导出。在某个远处，在组速度和旋涡Rossby波浪的光线的斜坡上的基本流动的不对称现象的影响主要是的结果表演在最大的风(RMW)的半径附近专注，而它在RMW外面减少。在不对称的基本流动的旋涡Rossby波浪的光线、正切的组速度的分布是仔细，与这个组上的光线、正切的基本流动的不对称的基本流动，和重要性的最大的速度的方位角地点有关，速度将随着半径变化。另外，在基本流动的更强壮的不对称现象总是对应于旋涡Rossby波浪的更快的外面的精力繁殖。简言之，组速度，并且从而，波浪精力繁殖和旋涡Rossby波浪光线在台风倾斜，将被基本流动的不对称现象改变。

简介：普通高中的学生学习VisualBasic高级语言程序设计课程,教师必须注意大纲要求。在VB程序设计课程中,分支结构适合于带有逻辑或关系比较等条件判断的计算,设计这类程序时往往都要先绘制其程序流程图,然后根据程序流程图写出源程序,这样做把程序设计分析与语言分开,使得问题简单化,易于理解。本文就如何提高VB中分支结构的教学质量,探索行之有效的教学方法,强调教师在教学活动中的灵活性和主动性,注重多种教学手段和方式的结合。
