Fortunately, the correct cutting speed can be estimated with reasonable accuracy from tool-life graphs or from the Taylor tool life Relationship, provided that necessary data are obtainable.
幸好，正确的切割速度可以根据刀具寿命表或者刀具寿命泰勒方程估算出来，并有一定的合理精度，如果在必要的数据都具备的前提下。
The resonance frequency shift in the space atomic clock prototype is analyzed in the paper. The preliminary results show that a higher accuracy is obtainable in the proposed new prototype.
在分析作者建议的一种新型空间原子钟原型中原子与场作用特点的基础上，探讨几种因素对该原型中原子跃迁频率的影响及相应的减少频移措施。
