First step, it uses the real power loss sensitivity with respect to the conductance of candidate branches to decide the real power loss which decides which loop switch should be opened.

第一步用线路损耗对支路导纳的灵敏度来近似计算打开开关引起的网络有功损耗增量，以此确定应打开的环路上的支路开关；

To switch between modes, an additional check is required in each pass of the main program loop.

要在模式间进行切换，需要对主程序循环的每次循环执行额外的检查。

Thus, the script does not count 10 lines, it counts 10 iterations of the loop generated by the -n switch (see "perldoc perlrun" and Listing 2 for an example of that loop).

运算符在一个范围内迭代。因此，该脚本并不是数10个行，而是对- n开关生成的循环迭代10次(请参阅“perldoc perlrun”和清单2，以获得该循环的示例)。

Sublime back-play seemed doomed to failure confronted by a solid defence - but Evans and Jordan Turner-Hall executed a lovely loop-switch that released Monye to score on the left.
