The existence of electric current in the conductor(not closed)which is cut-ting the magnetic lines of force(B-lines) variably in the magnetic field is pointed out, and the acceleration is discussed.
指出了在磁场中做变速切割磁力线（线）运动的导体（不闭合）中有电流存在，讨论了其运动加速度。
Suppose, along these lines, that A needs to communicate a particular kind of data set to B on a recurrent basis.
假设，遵循这样的路线，A 需要与 B 循环地就特定种类的数据集进行通信。
That is, a sequence a with 10 lines of code might have a very different degree of complexity and difficulty compared to sequence B of 10 lines of code written in the same language.
也就是说，用同一种语言编写的序列a和B都有10行代码，但是它们的复杂程度和困难程度可能根本无法相提并论。
