According to the existing literatures, the aim of interface management in construction project is, by identifying the interaction of such elements as information, material, finance, etc. among various participants, divisions, division members, or among connection of project entities or processes, to resolve the conflicts in professional division and cooperation between both parties (or multiple parties), thus realizing control, cooperation and communication, enhancing the integrated function of management, and eventually achieving optimized project performance
The new project, which is located at Fushan Science and Technology Industrial Park, Zhuantang , West Lake District, Hangzhou, covers an area of 1000 acre, with total construction area of 600,000 m2.

Alloys based on palladium are used as the membrane material.
In the study of functional materials it is very important to know the physical nature of the stability of structural-phase states, regularity in the formation and change of properties, but all the researchers begin with diagrams of state of potentially interesting metal systems [4,5].
