The most used is -r or --reload; this tells plackup to monitor your .psgi file (if you have a lib directory along side your .psgi file it will also be monitored): plackup -r 1.psgi.

最常用的参数是 -r 或 --reload；这会让 plackup 监控 .psgi 文件（如果 psgi 文件有相应的 lib 目录，也会受到监控）：plackup -r 1.psgi。

R/Cv OK, so that means that this is really instead of -1 R over Cv. it's really gamma minus one.

现在,变成了γ

e The charge on the anion times minus e, so there is the minus e squared, 0R0 and divided by 4 pi epsilon zero r naught, because now I am evaluating this function at r naught, one minus one over n where n is the Born exponent.

阴离子的电荷乘以，因此会有-e的频繁，除以4πε,因为现在我用r圈评估这个函数，1-1/n，n是波恩指数。

We also know how to figure out the energy of this orbital, and we know how to figure out the energy using this formula here, which was the binding energy, -Rh which is negative r h, we can plug it in because n equals 1, so over 1 squared, and the actual energy is here.

我们知道如何算出,这个轨道的能级，而且我们知道如何,用这个公式,算出能量，也即是结合能，等于，我们把n等于1代进来，所以除以1的平方，这就是能量。
