The dynamic equations were derived applying the Lagrangian multiplier method.

Discussion of solving the problem of motionless michanics by Lagrangian multiplier;

Hybrid finite element method constrained by Lagrange multiplier in couple-stress theory;

The constrained problem can be changed to a non-constrained problem by introducing Lagrange multipliers.

In order to decrease the picture quality fluctuation due to Q2 rate-control scheme in low rate and low delay video communication,firstly,a target bit-allocation algorithm was proposed with Lagrange multiplier method,where the coding information of previous one frame and the buffer status were taken into account.

In this paper,adopting the radar cross section as the constraint condition,a new conical aerodynamic configuration is presented using the Lagrange multiplier method,and the minimization problems are solved by the dynamic evolution method.

With Lagrange multiplier,Dirichlet boundary conditions are imposed along the essential boundaries.

With the loan s yield as the earning of financial asset and the volatility of loan as a criteria to reflect the risk of loan, a decision making model of loan risk portfolio s optimization was established through the solution of the problem of quadric program using the Lagrange multiplier with minimum risk in the feasible range.
