This paper expounds the necessity of making the technical transformation of the sulfur foam recovery system and the principles of Gore membrane system,puts forward some measures for improving Gore membrane sulfur recovery technique,and introduces the numerical statement,analysis and treatment of the faults occurring in the operation of Gore membrane system.

Research progresses of application for polyphosphazene materials in aerospace fields such as textiles, foam rubber, adhesive, high temperature-resistant flame-retardant coating layer, sealing material and lubricant material are discussed emphatically.

Aim at usage request,we selected the formulation system to used for developing foam rubber buoy.

By introducing several usual methods of solving the problem of foundation variance settlement of main and attached buildings,this paper puts forward the principles,conditions and working points to deal with variance settlement by means of plate form rubber,then offers some engineering examples of applying the method of the plate form rubber.
