In the article, the author comprehensively describes the multiplication and multiplicator in the Dirichlet Space and draws the conclusion similar to Dirichlet Space, the results of which are theorem 1,2, and 3.

Simultaneous Spectrophotometric Determination of Three Components in Satongfeng Injection by Multiply Factor Method;

Fe,Cu,Zn in aluminium alloy were determined simultaneously by using multiply factor method spectrophotometry.

In this paper,the basic principle and computing of multiply factor method applied to multicomponent a-nalysis were discussed.

Modified Lagrange multiplier method and its convergence analysis;

Deriving Variational Principles in Elasto-dynamics by Undetermined Lagrange Multiplier Method;

The control equation of the finite element method expressed by the base forces is obtained by using Lagrange multiplier method of the generalized complementary energy principle.

Then by using the multiplier method, it was proved that the closed loop system was exponentially stable if two boundary feedback controls were applied simultaneously to the beam s tip where the load was carried.

Using the multiplier method, we study the boundary feedback stabilization of the wave equa- tion with variable coefficient.

In this paper,we introduce the multiplier method and the non-monotonic technology,and give an effective algorithm for nonlinear bilevel programming,which is based on the multiplier method and penalty method.
