The excel method for solving the linear coupled equations 解线性方程组的电子表格法
Investigations on function for linear coupling of microwaves into slots 微波孔缝线性耦合函数研究
In general , there is no way to get the equations " analytical solution because of the characteristic of non - linear coupling 但由于这组方程是非线性耦合的,一般情况无法求出其解析解。
Through two - fluid and two - time - scale approximation , the dominating equations , which show the non - linear coupling between high frequency modulational field and the density disturbance of electrons and ions , are obtained 这组方程描述了高频调制场和电子、离子密度低频扰动之间的非线性耦合。
A 3 - d fem model was built up , which included a non - linear coupled thermal - mechanical analysis accounting for the temperature dependency of the thermal and mechanical properties of the material 建立了成形过程的三维非线性热力耦合有限元模型,模型中考虑了材料热物性参数和力学性能参数与温度的相关性。
