And we can use this propagation delay to store data!

而我们可以利用这个传播延迟来存储数据！

And then again, we have the propagation delay and the propagation delay is just the time, how long it takes from here when the rising edge occurs until the D value is actually forwarded to Q.

再一次，我们有传播延迟，传播延迟就是时间，从这里出现上升沿到 D 值实际转发到 Q 需要多长时间。
