是违背守恒定律而凭空消失了吗？

Is it lost, in violation of the conservation principle?

让我们试着用机械能，守恒定律解答一下。

Let's try the conservation of mechanical energy.

youdao

要服从质量守恒定律。

We write it subject to conservation of mass.

youdao

大声点。，lewin：，So, speak, up。，我们可以尝试用，机械能守恒定律吗？，这样用有什么问题吗？

LEWIN Shall we try the conservation of mechanical energy Is there anything wrong with that?

youdao

然后应用能量守恒定律去求得螺杆泵转子的设计规律。

Then, find out the design rules with the conservation law of energy.

youdao

能量守恒定律也获得简单的形式。

The law of conservation of energy also takes a simple form.

youdao

这根本就不违反能量守恒定律。

There is also no violation of the law of conservation of energy.

youdao

提出动力学系统守恒定律构成的一般途径。

To present a general approach to the construction of conservation laws for the dynamical system.
