摘　　要：利用行列式的性质与计算方法的技巧较易地解决了初等数学中的一些较繁与较难解决的问题,如运用行列式分解因式,证明等式与不等式,以及在几何方面的应用,从而体现用高等数学理论与方法解决初等数学问题的优越性.Using the nature and method of calculation techniques of determinant, some of the more cumbersome,more difficult problems in the Elementary Mathematics are resolved, such as： the determinant for decomposition factor and the proof of equations and inequalities, and the application of geometry, so as to realize superiority for the use of advanced mathematics and theoretical knowledge to solve the primary problem.

关 键 词：行列式 分解因式 不等式
