Sometimes, you can get by with a simple verification point, but sometimes you need conditionals, and sometimes you need to add a delay or a loop.

有时，您需要一个简单的验证点，但是有时您需要条件语句，还有时您需要添加一个延迟或者循环。

For example, a compiler may choose to optimize a loop index variable by storing it in a register, or the cache may delay flushing a new value of a variable to main memory until a more opportune time.

例如，编译器为了优化一个循环索引变量，可能会选择把它存储到一个寄存器中，或者缓存会延迟到一个更适合的时间，才把一个新的变量值存入主存。

The result proved that the cancellation performance of cancellation loop is decided by the amplitude imbalance, phase imbalance and delay mismatch.

指出环路的抑制性能是由前馈环的延迟失配、幅度失配和相位失配共同决定。
