According to the statistics data of melt inclusions and quenched glasses now available, the paper presents the average contents of H2O, CO2, Cl, F and S in ultrabasic, basic, intermediate and acid magmaticmelts respectively.
本文在现有熔融包裹体（和海底火山淬火玻璃）中挥发份含量数据的基础上。
After traditional interrupted quenching,the cold rollers made of steel 9Cr2 were deep peeled in course of using.
9Cr2钢冷轧辊经传统的双液淬火后 ,使用中出现了大量的深层剥落 ,后改用新的断续淬火工艺 ,消除了深层剥落现象 ,使冷轧辊使用寿命提高。
