利用贺州市四站1965~2004年春季降水资料，运用z指数和区域旱涝指数对贺州地区春季旱涝情况进行计算分类，并对重旱涝典型年份500hPa环流特征量和4月平均环流场展开分析，发现：贺州地区春季极易发生局部旱涝灾情，90年代以来重旱涝年份出现频率明显增大；在重旱年副高强度强，西伸脊点明显偏西，南支槽偏西偏弱，极涡中心偏东，亚洲中高纬高度偏低，在重涝年则相反。

Considering the skin effect and skin depth, a thin wall model and a thick wall model are derived creatively with different frequencies of discharge currents, which are used to study the relation between the spark location and the potential difference for a cuboid electrode.

本文从放电电流为任意函数入手，阐述了电极电位差法的检测原理，首次利用傅立叶级数推导了电位差与放电时间的关系，证明了放电电流为阶跃函数时，电位差与放电时间成指数关系；当放电电流中含有高频振荡时，电位差与放电时间的关系为指数曲线上叠加相移后的高频振荡；根据放电电流频率的不同，考虑到趋肤效应和趋肤深度，首创了薄壁模型和厚壁模型，研究了长方体电极下表面二维放电点位置与电位差的关系。
