The physical chemistry indexes of Chinese wines were investigated for the purpose of their classification according to variety or origin.

Interrelation of physical and mechanical indexeson clay of Panjin;

This paper analyzes and evaluates the physical and mechanical indexes of undisturbed soil samples gained from the borehole and vertical shaft in a certain water supply project, and corrects the physical and mechanical parameters of the soil sample from the borehole.

According to the data of soil test in the Hangzhouwan Bay,the paper statistically analyzes the variability differences,correlation and regression between physical and mechanical indexes.

The correlatability analysis of the physical mechanic indexes about high-saturated soil;

Bound water and free oxide effects on relevant physical index of clayey soil;

Through the analysis to production technology of Zinser drawing machine,expound the effect to DT fiber physical index of POYDT main process parameter DR,drawing velocity,temperature,pressure of compressed air and raw filament.

The selection of multifilament DTY process parameters and the change f multifilament DTY physical index and the cause have been discussed in this paper.
