By the analysis for the orthogonal experiments,the optimum scheme of bolt parameters is conformed.

The requests to heat insulation and gastightness of warehouse for low temperature grain storage and an optimum scheme of low temperature grain storage for three ecological areas were provided respectively.

Through analyzing the ecological characteristics in Meng-Xin area, the optimum scheme for grain safe storage of this area was put forward.

The optimization scheme comparison of the anterior suspension system of rhombic hanging basket;

According to study results,the optimization scheme of the heating patterns was put forward in the small town.

In this treatise,simulation of the initial photo-electronic tracking servo system shows the disadvantages in performance,and three kinds of optimization schemes based on PID controller are designed to improve the whole control system.

In this article, a mathematical model for optimizating gas gathering-distributing network without compressor station is set up and the operating program optimization of the network is realized by non- linear planning method.

It provides a scientific proof in program optimization and selection to demolition blasting.

It included the simulation modeling, the result analysis, the plan optimization and the improvement as well as the plan comparison and the summary to the plan.

For the mutual affection of all kinds of factors cannot be considered during the reservior engineering project optimization, the method of "uniform design" has been adopted instead of the optimized method in the steam -foam flooding project optimization design in block San 10.

And the project optimization of the blocks is implemented in test site of west block in Xing 6?7 area from several aspects of well, layer, agent selection and result forecasting combined with the reservoir characteristics and pattern configur.
