Through the analysis of image characteristic of crater wear in kentanium tool front face, arithmetic monitoring wear is designed, correlative software is exploited.───通过对硬质合金刀具前刀面月牙洼磨损图像特征的分析，设计了检测磨损的算法，并开发了相关软件。

wear form on the rake face is characterized as broad crater, which is directly influenced by the distribution of milling temperature.───受铣削温度分布的影响，前刀面磨损形态表现为较宽的月牙洼；

unusual sight is due to Herschel Crater, an 81-mile-wide (130-kilometer-wide) impact basin that gives the tiny moon a Death Star-like appearance when seen face-on (see a Herschel Crater closeup).───这不寻常的现象是由于陨石坑造成的，因撞击而形成一个81英里宽(130千米)的盆地。这使得这个小卫星表面如同死星一样的外表。
