教授：我没有写出来，但是是1，我们可以看到为什么是，因为它等于1/2的2，4减去，所以1/2的2，键序等于1。
PROFESSOR: And I didn't write up there but it is one, 1 and we can see that it's 1, 2 because it's 1/2 of 2, 4 minus 2, so 1/2 of 2, the bonding order is going to be equal to one.
新的Python解释器很容易改变这一次序，所以一定不要依赖于元素在dictionary中的特定次序。
This can easily change with a new Python interpreter, so it's important that you never rely on items being in a specific order within a dictionary.
步长如果为-1，意思就是倒序读取字符串，所以[：- 1]这个切片就会生成一个逆序的字符串了。
A step size of -1 goes through the word backwards, so the slice [: : -1] generates a reversed string.
电弧炉是一种严重的不对称冲击负载，它将产生大量的负序分量而污染电网，所以需要对其进行平衡化补偿。
Arc furnace is a typical unbalanced impact load. It pours a great deal of negative sequence component to power system, so measures shou ld be taken to compensate the arc furnace load.
负序距离继电器的行为与变压器绕组的接线无关，所以它是作为变压器后备保护的距离继电器的最佳选择。
The negative sequence distance relay gets free from the winding connection of the transformer. So it is the best choice to use the kind of the distance relays for the transformer backup protection.
输电线路的零序参数尤其是多回互感线路的零序参数是电力系统继电保护整定计算需要的重要参数，所以其准确测量具有重要意义。
The zero-sequence parameter of transmission lines especially of transmission lines with mutual inductances is of great important in the relay protection setting calculation of power system.
个次要配件中的每一 个次要配件将可序性的设计 （优化），然后将这个系统组合起，所以能计算出整 个系统的照明和成像性质。
Each of the two subassemblies will be designed (optimized) sequentially and then the systems will be combined so the illumination and imaging properties of the full system can be evaluated.
因为结构是实值型别，所以非同步处理序所做的改变不会改变原始结构的成员。
Because structures are value types, changes that the asynchronous process makes do not change the members of the original structure.
所以当你看在电影中看到这个过程的时候，你无法分辨这是在正常播放还是在倒序播放。
Since time is relative to the observer, it is impossible to divide it up into past, present and future in a way that is universally meaningful.
输电线路的零序参数尤其是多回互感线路的零序参数是电力系统继电保护整定计算需要的重要参数，所以其准确测量具有重要意义。
The incremental method, differential equation method and integral equation method are three main methods in zero-sequence parameters on-line measurement of transmission lines with mutual inductance.
