例句與造句

1. Abstract : the paper analyzes the wear resistance and anti - adhesion of 20 and 45 steel formed in austenitic ion - nitrocarburising and comparisons to the general ion - nitrocarburising . the experiment shows that austenitization - nitrocarburising can be carried out at 590 700 , its wear resistance and anti - adhesion is the best at 630 ， the worst at 660 and anti - adhesion is the best at 630 ， the worst at 660 and the mediate at 570 600 . with the help of raising processing temperature properly and speeding up the process the wear behavior can be improved
   文摘:研究20鋼、 45鋼經(jīng)奧氏體離子氮碳共滲后的耐磨性和抗咬合性，并與普通離子氮碳共滲后的作了比較，試驗表明:在570 700范圍內(nèi)進行離子氮碳共滲后，其耐磨性和抗咬合性以630處理時為最佳， 660處理時最差，而570 600處理時則介于兩者之間，通過適當(dāng)提高共滲溫度，再提高滲速，從而縮短共滲時間的同時，可以提高耐磨損性能。
2. It's difficult to find austenitization in a sentence. 用austenitization造句挺難的
