So, in particular, only if you have a conservative field, a gradient field.

特别地，仅当是保守场，即有势场时才可以使用。

If you are working in a very conservative field, will others look at your tattoo in a bad way?

如果你在相当保守的领域工作，别人会不会对你的纹身有负面的看法？

The major results are:(1)the movement of high energy electrons in a powerful laser field is a conservative field movement, thus the condition for in-phase coupling is obtained;

主要结果是：①高能电子在高功率激光场中运动是一保守场运动，由此得到同位相耦合的条件；
