The absorption rate constant expresses the speed of absorption. 吸收速率常數表示吸收的速度。
Estimate the potency degradation rate constant at low temperature with that at high temperature according to Arrhenius equation. 根據阿倫尼烏斯方程，從較高溫度下效力衰減的速率常數估算較低溫度下的速率常數。
Methods are available for the measurement of absolute velocity constants but they are by no means easy to apply. 雖然某些方法對測定絕對速度常數是合用的，但不容易實施。
It becomes desirable to seek either a determination of individual velocity constants or some meaningful ratios of velocity constants. 我們希望能找到測定各步速度常數的方法，或某些有意義的速度常數比值。
