如果Freqsec(1,R + 1)> Freqsec(R)* 1.01 |频率秒(1,r+1)
或者
如果频率秒(1,r+1)>频率秒(r)*1.01 | |频率秒(1,r+1)<频率秒(r)*0.99
The first of these is more general. The second of these, , is the short-circuiting OR that does not bother to evaluate the second expression if it already knows the final result after the first operation. The operator can only be used between expressions that produce scalar outputs.
