这种分析方法在数值求解时只需计算低价次的传递矩阵和行列式值，因而可在PC机上进行。

This analysis method with numerical calculating only requires calculation of lower-order transfer matrix, so that, it can be made with microcomputer such as IBM-PC.

由结构刚度矩阵行列式值为零的失稳条件导出结构失稳特征方程，从而精确地确定系统临界力值。

The precise critical force of a system can be deduced from the fact that the determinant of stiffness matrix of the system is equal to zero in the critical condition.

我之所以没有把这些放在一起，是因为接下来你们将会得到，两个竖着的表达式，这个是绝对值，而这个是行列式。

OK, so I didn't put it all together because then you would have two sets of vertical bars. See, this is a vertical bar for absolute value. This is vertical bar for determinant.
