所以，当我们想要知道中子的变动率，那是时间方程，我们会写下这个表达式。

So if we wanna know the rate of change of neutrons as a function of time we will write this expression.

利用分支裂隙扩展建立断裂力学模型，可导出节理内聚力的一种具有封闭解的时间方程。

Fracture mechanical model is developed by utilizing subcritical crack growth, leading to an equation that has a closed solution for joint cohesion as a function of time.

youdao

So, for example, if we're to hold the time constant, this makes it a lot simpler of an equation, because what we can end up doing is actually crossing out this whole term here.

比如说，如果我们把时间,定为常数，这使得方程,大大简化，因为我们可以把,这一项划掉。
