She considers the currentfluctuation span of plus or minus 0.5% appropriate for the time being, but said the central bank would not rule out widening that spread in the future.
胡认为，目前汇率波动在 0.5% 上下是合适的，但是不排除央行放宽这一限制的可能性。

By using the WKBJ method, the average of currents and square of the current are calculated, the results show the existence of the currentfluctuation, which causes the noise in the circuits.
