摘要

这项工作的目的是研究发生在海面上的闪电现象。本文主要研究雷击海水表面时海水上的放电电流分布。研制了由水下电极和水面电极组成的模拟海况系统，利用火花放电模拟闪电现象。实验采用正负放电法进行。通过对不同电导率的自来水和盐水的电压、电流波形、水面和水下放电条件和电流分布的平均值，观察了不同电导率的自来水和盐水的放电特性。正放电和负放电时的放电特性基本相同。因此，本文只讨论正放电的数据。

Experimental studies of current distribution in stratified seawater under spark discharges

The objective of this work is to investigate lightning phenomena that occurred on sea surface. This paper is focusing on observing discharge current distribution on seawater when lightning strike on seawater surface. An imitation of sea condition that composed of an electrode system of underwater electrodes and water surface electrode was developed and lightning phenomena was imitated using spark discharge. The experiment was done using positive and negative discharge. Discharge characteristics of tap water and saline solutions with different conductivity was observed by the mean of voltage and current waveforms, discharge condition and current distribution both on water surface and underwater. Discharge characteristics during positive discharge and negative discharge show almost same characteristics. Thus, only data for positive discharge are discussed on this paper.
