质量百分数 meaning in English

mass percent

The relative content of a particular element or constituent ( i ) within an alloy , usually expressed in weight percent or atom percent . also call it concentration
合金中某一元素或组分的相对含量，通常用质量百分数或原子百分数来表示。也称为浓度。
The experiments showed that wc and vc can dissolve mutually in the carbonizing reaction . when wc ' s content exceeds vc ' s , vc will dissolve into wc and make wc ' s crystal lattice bring aberrance and become wc1 - x , contrarily when vc ' s content exceeds wc ' s , wc will dissolve into vc and also make vc ' s crystal lattice bring aberrance . the surface cermet composite has high rigidity and well wear - resistance
( 7 )采用铸造烧结技术，通过加入毗颗粒和v班一vc的原位放热反应成功制取了碳化物陶瓷质量百分数超过60 %的表面金属陶瓷材料，实验证实wc与高温碳化反应生成的vc相互可以很好的固溶，当wc的含量超过vc时， vc可以固溶到wc中，使wc的晶格发生畸变，成为昵卜: ，反之当vc的含量超过wc的含量时， wc可以固溶到vc中，也会造成vc的晶格畸变。
