Comparing with former prediction methods , there are two progresses in it . first , the concept of fracture richness index is advanced and thus extend of fracture ' s richness can be numerable 与以前的预测方法相比，本次论文在以下两个方面有了改进：第一，提出了裂缝发育指标的概念，从而能够对裂缝发育程度进行量化。
2.
These numerable key parameters not only simplify the dimensions of design space for the robust optimization design of a microgyroscope , but also provide a special quantitative reference to the accuracy control in the fabrication procedures of microgyroscopes 这有限关键参数的获得，不仅为微陀螺的健壮性设计提供了方向，同时也为实际微陀螺的加工控制提供了量化的参考依据。
