To conquer the influence of the cross term, a weighted mean method is proposed.

为了克服交叉项的影响，提出了加权平均的方法来改进算法。

So in this case the cross term represents constructive interference between the two 1 s atomic wave functions.

在这种情况下交叉项代表两个，1s原子波函数的相干干涉。

After adopting the smooth pseudo WVD that reduces the interference of the cross term, the series is transformed into a two-dimension distribution of fluctuation energy.

采用平滑WVD可消除交叉项的干扰，并将网络流量序列转换为二维空间的波动能量分布。

In particular, he looks for instances in which the short-term averages cross over the long-term averages, seen as a sign that momentum is accelerating either to the upside or downside.
