critical volume fraction meaning in Chinese

临界体积分数

The resistivity - temperature curve can be predicted by using this mathematical model , which was in good agreement with the experimental data when the cb volume fraction is close to the critical volume fraction
利用这个数学模型，还对两种ptc材料的阻温曲线进行了预测，与实测结果比较发现，当炭黑含量在渗流阈值附近时，预测值与实测数据吻合很好。
It shows there was a critical volume fraction . only when the initial pore volume fraction of the perform equal to the critical volume fraction , the free si was fully replaced with the mosi2 particles . otherwise . there would be free c and free si in the infiltrated materials
结果表明，坯体的初始空隙率存有一个临界值。只有当坯体的初始空隙率等于此值时，材料中的游离硅才可能被mosi _ 2完全取代。
By using this model , the contribution of the thermal volume expansion of the matrix to the ptc transition of the composite is quantitatively estimated . the theory and experiment revealed that the conductive mechanism of abrupt resistivity increase at ptc transition region was equivalent as abrupt resistivity increase at the percolation curve close the critical volume fraction
可以利用这个模型，对基体体积膨胀对ptc转变的贡献进行了定量分析，表明ptc转变区的电阻突变与渗流曲线在临界体积分数附近的电阻率突变在导电机制上是相同的。
