For those slurry pump with expeller seal combined with packing or packing seal, the shaft together with impeller should be able to be rotated along pump rotation direction by hand. Otherwise the impeller clearance should be adjusted (For those slurry pump with mechanical seal, adjust the impellergap first, then mechanical seal).

对于填料加付叶轮组合式密封或填料密封式渣浆泵，用手按泵转动方向转动轴，轴应能带动叶轮转动，不应有摩擦，否则应调整叶轮间隙（对于机械密封式渣浆泵，应先调整叶轮间隙，再调整机械密封）。

The Chinese teachers should awake to the necessity of arousing and treating the students interest to learn expository writing skills in order to achieve good results.

The problem of stabilizing networked PI control systems with fuzzy logic compensation is studied by applying the extension of the Hermite-Biehler theorem to the quasi-polynomial stability problem.

该方法的优点是可利用现有的确定性系统的设计方法设计控制器，缺点是由于缓冲区将时滞都转化成最大时滞，降低了系统应有

How would a contemporary of Galileo's have been able to extrapolate from the telescope to the iPhone?

这个当代版的伽利略望远镜能够发挥它应有的作用吗？

Therefore the dispersion curves obtained in the field are primarily consisted of the first mode. For a heterogeneous elastic solid consisting of three homogeneous layers whose interlayer has low velocity, the phase velocity V〓 of the first mode will also close up to the Rayleigh wave velocity of the bottom layer when frequency f→OHz, but V〓 of the first mode will close up to the shear wave velocity of the interlayer when f→∞, and there is a cut-off frequency at high frequency region for the first mode and V〓 close up to the compressional velocity of interlayer when interlayer is liquid.

当三层固体介质中存在软夹层时，若f→OHz，则其基阶模式的相速度V〓→V〓（V〓为最底层介质的瑞利波速度）；若f→∞，其基阶模式V〓→V〓（V〓为中间层介质的横波速度）；若三层介质中存在液体夹层，当f→OHz时，基阶模式V〓→V〓，而基阶模式在高频段存在一个截止频率，截止频率处的瑞利波速度V〓→V〓；由此可判定，野外实测的相速度频散曲线不仅有基阶导波模式，同时还应有高阶导波模式波的存在，接收信号中存在模式间的跳跃，因此频散曲线会产生"之"字形现象。

In our model, the dose-dependent inhibitory and facilitative effects were observed respectively in niacinamide and α-MSH treated group.
