Feb. 1988, quasi-biennial and quasi-3-to-4-year oscillation are invenstigated. It is found that the two oscillations are propagating from west to east at all levels, being out of paase for the tropics but in phase for the mid-latitudes; for the latter oscillations in West Pacific, it travels equatorially from both mid-latitudes at low-levels while from south to north through a well-defined channel at...

结果发现：纬向风准两年、准3─4年振荡在热带地区上、下层均一致自西向东传播，但位相相反；在中纬度地区，纬向风准两年、准3─4年振荡上、下层均盛行自西向东传播，且位相一致；西太平洋地区低层纬向风准3─4年振荡均为从南、北半球中纬度地区向赤道传播；高层纬向风准3─4年振荡在175─140°W附近存在一明显的通道，且为自南向北传播，而且在经向上呈1波特征。

To control the body height of vehicle with hydropneumatic active suspension system, this paper presents a new control strategy to eliminate the oscillation arising from friction force and occurring in conventional PID control.

As a further studying, the "beat" oscillation phenomenon appearing beforce the chatter occurs is analyzed and it is found that there is a self-excited vibration frequency f during the rilling. Farthermore, if the frequency f is infinitively close to one of the natural frequencies of the rolling mill system then an instability will occur.

作为颤振振因的深化研究，对颤振出现前的&拍振&现象进行了分析，推证了轧制过程中有一个自激频率f存在，而且当它与轧机系统的某个固有频率无限接近时会立即引起轧机工作的不稳定。
