Now, we're not quite there because now we have two copies *b=temp of 2 so the last line of code says *b gets temp.

现在，我们还没有达到目的，因为现在我们有两个2的拷贝，最后一行指明。

The synchronization principle of IRIG-B code is analyzed. When applying IRIG-B code in substation IED, neither communication messages of fieldbus nor multiple pulse signals of GPS are needed.

分析了B码的对时机理，指出变电站的智能设备采用B码对时，就不再需要现场总线的通信报文对时，也不再需要GPS输出大量脉冲接点信号。
