m×n广义行列式按一行展开的性质

笔者曾在“m×n广义行列式的定义及运算性质”一文中详细介绍了m×n广义行列式的概念及运算性质。为了今后研究问题方便，本文将给出它的另外一个重要的运算性质——按一行展开定理。这个性质在某种程度上将简化广义行列式的运算，但更主要的是在理论上的应用价值。

The Nature of the mxn Generalized Determinant in One Line

The author has presented the nature of generalized determinant expended in one line on the article of ＂the Definition and Operation Nature of m xn Generalized Determinant Expended in One Line＂ For future research on convenience, the article gives another operation property--determinant in one line, which in some extent simplifies the operation of generalized determinant. Theoretical value is mainly reflected.
