等价方程

It is proved that the cavitated bifurcation equation is equivalent to a class of normal forms with single-sided constraints near the critical point by using singularity theory.

用奇点理论证明了，空穴分岔方程在临界点附近等价于具有单边约束条件的正规形。

In manycases,they are equivalent.They describe the same equations in different math-ematical formalisms.

在许多情形下，它们是等价的，它们是同一问题的不同出发点，它们对同一方程给以不同的数学形式。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
