失稳后的弹性线采用精确的曲率微分方程式。
The analytical solutions for these reactor models are shown to agree very well with the numerical solutions to the exact differential equations.
两种模型正合微分方程的解析解与数值解表示出十分的吻合。
an exact differential. Or, if you don't like exact differentials, a the corresponding vector field with i, j and k instead, a gradient field. Let's just apply the criterion.
它是一个恰当微分，如果你不喜欢恰当微分，和b满足，for，which，a，and，b，is,用i，j，k代替的相应的向量场，就是有势场，我们用判定准则来做。

So the delta v here is an exact differential, but this dw is not.
你是如何,到达这个状态的。
