摘要
介绍了一种改进型雷击模型，它既兼有雷击本身的特点，又具有相对简洁的数学基础。模型对于特定的雷电通道底部电流，采用了汉时间常数，取得了比单时间常数更好的拟合效果.
An improved return stroke model(DU model)that is both physically oriented and has a relatively straightforward mathematical basis is introduced.The current at the channel base is specified, and use two time constants can get the much better shapes than single time constant.
