Determination the Content of Peoniflorin in Ruxianzengsheng Granula;

Ten mice were subcutaneously injected with proteins derived from the isolated granulated metrial gland cells (as experimental group), the others with PBS (as control group).

Based on theories of grains size and dense packing,our research took oil-well cement with high-resistance to sulfur,Jiahua G,and hematite as basic materials and prepared a kind of cement slurry with density varying from 2.

The paper summarizes the formation,movement model of the debris and grain,the condition and mechanism of the oxides formation in the course of thermal wear of the metal composites.
