reactivity coefficient的用法和样例：
例句
- Therefore, the problem predicting the Jominy curve changes to one calculating the hardenability coefficient.
因此，端淬曲线的计算预测问题转化成淬透性系数的求解。 - It was demonstrated that the hardenability coefficient depends on the chemical composition under the condition of the standard Jominy test.
在端淬试验标准状态下，淬透性系数取决于钢的化学成分。
