Abstract: For obtaining good quality plastic product of mouse,the solid sample of mouse was built, the top and down cover deformation of mouse were drawn as well,further more,the mouse assembly was also selected.Up and down cover of mouse moulds and the whole style mold were gotten by Pro/E,gate location of mouse up cover was analyzed,the project and net model were created,thus the joint of gate location area centre could be found,the pouring system location was set and optimized.

Abstract: Trend assessment of safety management status described the variation of the safe state during the process of construction, and it is an early warning of safe accidents to some extent. So the study of it is becoming a burning question. Aim at the uncertainty and the dynamic characteristics of the system; the trend assessment model of bridge construction safety management status has been set up using the theory set-pair analysis and Markov chain. The application results show that this model can predict the safety management status of the next and final stage relatively accurately, and it can play a guiding role in preventing safety accidents.
