So the spring force is opposing that, so the spring force has a minus sign here to indicate the direction.

So to make things simpler we are using this convention and you just put a minus sign if you are doing physics.

我们只是借用了这个物理概念来简化问题，你算物理题的时候加个负号上去就好了。

If the pattern specifies a leading minus sign for negative input, a trailing minus sign is ignored.

如果该模式指定前置负号为负输入，后置负号将被忽略。

We have a minus sign; again, that illustrates that it is restoring.

这里有个减号，表明它在恢复。

When there's no explicit negative pattern, a leading minus sign is assumed in combination with the positive pattern.

没有显式的负数模式时，假设正数模式中包含前置的负号。

Then, we take that entry, multiply it by that determinant but put a minus sign.

然后是这项，乘以这个的行列式，但要添上个负号。

Appending a minus sign to the option explicitly disables it.

将减号追加到此选项将显式禁用它。

And the minus sign indicates that he has to throw the sandwich backwards.

这里的减号意味着，他不得不把，三明治向后扔。

Notice the difference: there's a plus sign here; there's a minus sign here.

注意这里的不同：，上面是加号，这里是减号。

The minus sign is telling you that the force is always pointing in the direction of the potential energy.

力一直是指向，这个方向的，它和势能的增长方向，这就是负号。

The minus sign here disappears when you take the derivative on the bottom.

当对下面做微分的时候，这里的负号就消失了。

So, if we do, OK, let's put a minus sign in front.

将一个负号放到这前面。

Note that any leading plus or minus sign is not actually considered part of the constant;

请注意任何前导地正号或者负号实际上都不认为是常量的一部分；

The inner boundary either goes clockwise, or you put a minus sign.

内部边界曲线是顺时针的，或者加一个负号。

You would have found a minus sign here, and that's exactly the same.

这里就会有，一个负号，结果完全一样。

The reason for the minus sign is the same as in Section 33-2.

出现负号的原因与33-2节所讲的相同。

So, the system does work on the surroundings, hence the minus sign.

系统对环境做功，因此符号是负的。

And I feel like I've got a minus sign missing somewhere.

我感觉我在什么地方漏了一个负号。

I find it better without milk or sugar for it quenches my thirst.
