一个激光谐振腔的稳态过程模拟程序。通过设置波长，腔长等参数可以真实的反映出激光谐振腔的稳定振荡过程。-a laser resonator steady state process simulation program. By setting wavelength, the cavity length parameters can reflect the true laser resonator stability oscillation process.

Hopfield网络是一种典型的单层反馈网络，这种网络可以分为离散型和连续型两种，Hopfield网络是一个动力学系统，在确定连接权重后，若输入某个向量之后，网络将不断演化，一般情况下系统将趋向某一个定态，称为状态空间的不动点吸引子。-Hopfield network is a typical single-layer feedback network, Such networks can be divided into discrete and continuous two, the Hopf

PQ分解法，有些还需要改进，该程序所对应的例子是东南大学陈珩编的《电力系统稳态分析（第二版）》的例4-5-PQ decomposition, some also needs to be improved, The procedure corresponding to the example of Southeast University, Chen Heng addendum to the "steady-state power system analysis (second edit
