When exciting Sin voltage source is applied to proper port, the stability of network depends on the sign of active and reactive components for fundamental-wave current entering port of networks.
若在适当端口施加正弦电压源，则网络的稳定性取决于进入端口基波电流的实功与虚功成份的符号值。

But if linearly superpose the two fundamentalwave solution, it does not have the significance because their background are nonlinear.
但简单的将这两个基波解进行线性迭加是没有意义的，因为它们的背景是非线性的。

The conversion efficiency between the fundamentalwave and the th emission is roughly constant over the length of the plasma channels.
