By the use of generalized modularization technique and holographic modeling technique to setting up the main structure,the primary model and the master document of the product family the detailed development process of product was realized.

According to the structure features of overhead traveling crane and on the basis of existing parametric design technology,proposes product-level parametric design technology based on the holographic modeling and master structure,establishes holographic model library and development its parametric program.

This paper studies the bicycle combing the technology of product developing,and the product master model,master document,master structure of the product are established on the basis of ABC analyses for parts and parameter of bicycle.

Product master structure, master model and master document are built up after the development process and support the design process.

This is because the primary structure shares the seismic loading acting on the sec.

It is made up of primary structure and secondary structure.

Finally,the ageing mechanisms of silicone rubber foam materials were deduced from some analyses,not only the molecule chain structure changes of silicone rubber during thermal-oxydative process,but also the cellular.

Because of the low strength,an optimal tension control system based on the master-slave structure is developed in order to prevent the breakage of the micro wire electrode.

This paper puts forward the designing method of diaphragm wall being used as main body structure,including the disposing manner,designing construction joint and structure joint and the calculating method of bearing capacity of diaphragm wall.
