)on the comprehensive quality(maximal warp,volume shrinkage ratio and surface sink index)of mobile phone cover injected part are studied by using Moldflow analysis software and orthogonal experiment method.

Fair,just,scientific and rational supervision and evaluation system is conducive to the sustainable improvement of comprehensive quality of medical institutions.

Based on a series of surveys and researches,the paper introduces the indexes for evaluating the comprehensive quality of the port project according to the port project characteristics,establishes an evaluation system for the port project with fuzzy method and presents the case-model for Nansha-port project evaluation.

In order to settle the traditional tool s problems of limited precision and applicability, the technique of tractor crankshaft synthetic measurement based on virtual instrument is introduced.

With the rapid development of manufacture technologies, the synthetic measurement of profile with large range and high precision has become more and more imminent.

The design plan of synthetic gauge for bisected tee-connection has been fixed through research.

This paper introduced a new method of designing of synthetic gauge for measuring the hole position, according to the condition that diameter tolerance is large and the hole position accuracy is high.
