Analysis of influence causes on qualified rate of defects detection of tyre;

Influential factors analysis on detection qualified rate of food samples;

Several suggestions about improving the corrosion qualified rate of strain gauge;

Discussion on improving the qualification rate of R03P battery for the first time;

According to packaging types,the qualification rate in packaged products was 96.

One -turn -qualification rate for binocular is raised effectively by taking corresponding measures.

Analysis and predicte the disinfection percent of pass for endoscope

The measures to improve the percent of pass of aging property were obtained,such as micro-Ti treatment and finishing rolling temperature control.

The effect of smelting SiCr by dualprocess to percent of pass for export is analysed.

TV Glass Panel Yield and the Quality Cost Optimization;

Increase of the Insulation Yield of Stripping Capacitance and Metallizing Polycarbonate Film Capacitors;

Through adjustment of the width of the slot plus using turning process instead of milling process for bur removal with the addition of proper inspection method,for upgrading the quality of the joining parts,consequently avoiding fiber burring,yield going up from 92% to 99%.

This paper uses K-Means Cluster analysis to analyze the key indicators in the pass rate of the CPA examination in the 2003 in China,analyzes the indicators in the other eight provinces by means of discrimi- nate method,and finally defines the four categories of zones which is the pass rate of the CPA examination distribution in China.

For the dimensional quality evaluation of complex mechanical products based on small sample, an empirical Bayesian infer algorithm for pass rate estimation was provided, which took full advantages of the historical inspection data and the information of current sample.
