The results show that the heave compensation system with self- adjustable fuzzy controller can restrain the vibration and decrease the intensity effectively, and the amplitude is reduced by 75%-85%. The self-adjustable fuzzy controller is superior to the general fuzzy controller in the adjusting time, and the effect of control and adaptability, which accords with the design demand of the heave compensation system completely.

One radial vibration probe positioned in " Y " plane for each rotor after impeller. For vibration display, alarm and shutdown, function wired to control panel.

每级叶轮后的转子轴处都装有一径向振动探头，线接至控制柜，为每级振动的显示、报警和停机。

In this work, the N〓-broaden halfwidths of the pure rotation and v〓 band of water vapor have been calculated by using QFT theory, which involves the three intermolecular interactions: short range, dipole-quadrupole, and quadrupole-quadrupole (denoted as QFT〓).

本文首先利用考虑短程强相互作用势、电四极矩〓-电四极矩〓和电偶极矩〓-电四极矩〓相互作用的QFT方法，计算了水汽分子纯转带和V〓振动带谱线的氮分子碰撞加宽线宽，以及V〓振动带谱线线宽的温度依赖关系。

This paper puts forward the method of using the vibrating isolation ring to reduce noise ,and advances the definite principle of the rigidity of the vibrating isolation ring and calculation formula.

提出了用隔振环来降低振动筛噪声的方法，以及隔振环刚度的确定原则和计算公式。分析了安装隔振环后，对振动筛固有频率影响不大，可保证工作频率是最高固有频率的两倍以上，可保证振幅不低于原振幅的98%，基本上不降低工作效率。

However, it hardly has the effect for the rigid-body translational vibration. There is the best effect of damping and energy absorption for distortion vibration.

在40-100 Hz范围内有较好的减振、吸能作用；对于整体平移振动不起作用，而对于扭曲振动效果最好。
