例句
- The machinability of crystal material is studied, and the influence of the cutting condition on surface roughness is analyzed.
本文探討了晶體材料的切削加工性，重點分析了切削條件對錶面粗糙度的影響。 - First, if the nature of dry-heat sterilization is due to oxidation, the crystalline material may impede the diffusion of oxygen to the cell, thus extending the time to sterilize.
第一，如果幹熱滅菌的本質是由於氧化，晶體材料可能阻礙氧擴散到細胞，從而延長了滅菌時間。
