This article has described the function and establishment method of the material consumption process ration,and the effect of the blank material selection on the ratio has been illustrated as well.

By comparison of the inner pressure and the material consumption between the understructure of the silo with an intermediate post and that without,a new understructure of the silo was offered,which bore the advantages of resonable pressure distributions,minimum material consumption,low cost and easy construction.

In order to decrease material consumption and to increase the ratio of performance to price of the products,the diesel engine of the Model 2110A,which is come of the Model 2105A,is developed.

The Salisbury screen s retro-reflection coefficient formula was given,which satisfied the general matching law and provided a theoretical basis for the new direction in which the loss material was used as the insulating layer in Salisbury screen s optimized design.
