lumped versus distributed systerms（集总与分散系统）

该小节给出了集总和分散系统（集总和分散电路）的定义和判断标准，同时给出了示意。

The reaction of this systerm to the incoming pulse is distributed along the trace ，which we label a distributed systerm.

Systerms physically small enough for all points to react together with a uniform potential are called lumped systerms.

如果线长和信号上升沿长度的比值超过1/6，通常判断该系统是分散系统。
