- This is in favor of ont only distinguishing the signal term,but also reducing the cross term. 这不仅有利于区分开每个信号项，而且有利于减少截项。
- In thispaper, cross term interferences of Wigner Drstribution and principle of smoothing to eliminate them are discussed by using mathematical model of ECG signal. 本文结合心电信号的数学模型讨论了维格纳分布的交叉干扰问题，以及运用平滑处理消除这一干扰的原理；
- 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。
- The shortcoming of Wigner-Ville is the severe cross terms as indicated by the existence of negative power for some frequency ranges. Wigner-Ville分布克服了短时傅立叶分析的部分缺点，具有较高的分辨率，但存在严重的交叉干扰项。
- The main frequency-domain parameters, which are discussed here, include modal numbers, cross terms of force spectra, and cross terms of modals as well as damping ratio. 参数分析的内容包括参振模态的数目、力谱交叉项、模态交叉项、结构阻尼比，并得到了一些有价值的结论。
- Discrete-time Indefinite Linear Quadratic Control With Cross Term 带有交叉项的离散不定随机线性二次控制问题
- Through comparing several kinds of time-frequency distributions, CWD is consideredas a perfect distribution, which is very fit for time-frequency analysis with high resolution and can compress cross terms effectively. 通过几种二次型时频分布的对比分析,认为CWD在具有较强的时频聚集性的同时又较好的对交叉项进行了抑制,适合于进行爆破振动信号的时频分析。

- In the short term, the medicine may not be very effective. 从眼前来看，这药可能疗效不是很大。
- Unlike the traditional kernel function methods to suppress cross terms, our method not only reduces the interfering cross-terms but also preserves the superb time-frequency concentration of the WVD. 不同于传统的抑制交叉项的核函数方法, 该方法抑制交叉项的同时, 保持WVD了高时频聚集性。
