The results indicated that the content of cytosolic CaM in cells treated with exogenous Ca2+ has increased indistinctively, while fluorescence intensity in cells treated with TFP decreased. So we believed that exogenous Ca2+ has little effect on the expression of CaM. High concentration of TFP can enter yeast cells and combine to CaM to make it inactive, which is the reason that TFP restrain the growth of yeast cells. 5mmol/L EGTA could completely arrest the cell proliferation of MFP7 after 28h, when the fluorescence intensity in cells wasobviously increased with flow cytometry and LSCM.

被较高浓度TFP处理过的MFP7胞内荧光强度则相对较弱，推测是因为TFP进入胞内与CaM结合从而使其失活，这也是高浓度TFP抑制酵母细胞增殖的原因。5mmol／L EGTA处理28h左右后，酵母细胞的生长被抑制在G1晚期，此时通过细胞流式法和在激光扫描共聚焦显微镜下观察到胞内荧光强度显著高于对照，说明CaM的表达水平在G1后期开始上升；回加10mmol／L Ca~(2+)处理24h后，细胞开始恢复生长，细胞流式法测定胞内荧光强度有所下降，表明多数细胞完成G1／S转换，进入生长对数期。

System speaking of the Master CAM, first must establish the components the geometry model, according to the components actual size, draws its processing part the contour line, does not need to draw the entire components the model, guaranteed the computation production the cutting tool way coordinates accuracy, and may use the Master CAM Chinese Library level the function, when determination cutting tool way, transfers or the hideaway, the selective treatment needs contour line; Next, the formulation processing craft and the definite craft parameter, chooses the cutting tool, the processing semi finished materials, the work piece origin of coordinates again and so on, establishes the work piece coordinates system, definite work piece coordinate system and engine bed coordinate system relative size, thus obtains the components processing correct cutting tool way; Finally, the simulation function which system provides using the Master CAM, the realization simulation processing.
