essential boundary condition

基本解释

The transformation method is used to impose the essential boundary condition.
利用变换法施加本质边界条件；
In the higher dimensional case, we give a sufficient condition, and also point out the connection between boundary representations and essential normality of modules.
在高维的情形，给出了一个充分条件，并且指出边界表示问题与模的本质正规性之间的密切联系。
But the imposition of essential boundary condition and the treatment of discontinuous field variable and the derivative are somewhat troublesome, and the computation cost is large.
然而自身也存在着计算量大、边界条件和不连续的场变量及其导数处理上的困难。
