Subsequently, to heuristically measure the relative importance of candidate cuts, relevant metrics are studied based on "cut discernibility matrix".

其次，论文研究了通过“断点分辨矩阵”来度量候选断点重要性的启发式方式。

When measuring the importance of a candidate cut, both the characteristics of columns and rows of this matrix should be reasonably taken into consideration.

度量候选断点的重要性不但要考虑该矩阵的列方向特征，而且还要以适当的方式考虑矩阵的行方向特征。

To cut down great calculation of assembling and disassembling of stiffness matrix in the nonlinear procedure, the initial stress method is introduced to resolve the nonlinear equations.

使用初应力法对非线性方程组进行迭代计算，避免了组装和分解总体刚度矩阵的繁杂而庞大的运算。
