The highest probability now is going to be along the x-axis, so that means we're going to have a positive wave function every place where x is positive.

概率最高的地方是沿着ｘ轴，这意味着只要在ｘ,大于零的地方波函数都是正的。

In other words, T surrounding dS has to be greater than zero, and of course temperature is always positive.

换句话说这就意味着，环境温度T乘以dS必须大于零，当然环境温度T是正的。

The two analogies we use " was strengthening our immune system or stronger "psychological engine" that has the capacity to endure more not just from the negative to zero, but also from the zero to the positive.

我们使用的两个类比,是加强我们的免役系统或加强“心理引擎“,获得更强大的忍受能力,不只是从负到零，还要从零到正。

And when we're talking about the amplitude of the wave, we're talking about the deviation from that average level. So, if we define the average level as zero, you can have either a positive amplitude or a negative amplitude.

当我们讨论一个波的振幅时,我们说的是偏离平均位置的量,如果我们把平均位置,定义为零的话，那幅值不是,正的就是负的，有时候人们在。

If we look at our last structure here where we have nitrogen the middle, we can also figure out all those formal charges, and in this case we have plus 1 on the nitrogen, we have minus 2 on the carbon, and then we end up with a 0 on the sulfur there.

如果我们来看看最后一个结构,在中间的原子是氮，我们同样可以计算出所有的形式电荷，而在这种情况下，氮为正一，碳为负二，而最后硫为零。
