With the rotating screw and mesh, these seals in the pump suction space evolving, the suction chamber in which liquid enclosure and along the screw axis from the inhalation of room to move continuously push exhaust side, will be closed in the space been discharged in the liquid, like a nut when the screw rotation continued to move forward is the case, this is the basic principle of the screw pump.

随着螺杆的转动和啮合，这些密封空间在泵的吸入端不断形成，将吸入室中的液体封入其中，并自吸入室沿螺杆轴向连续地推移至排出端，将封闭在各空间中的液体不断排出，犹如一螺母在螺纹回转时被不断向前推进的情形那样，这就是螺杆泵的基本工作原理。

In order to promote the application of organic manure and chemical fertilizer in the rotation of Flue-cured tobacco rationally, the effect of different organic manure (crop straw, oil cake, fully-fermented pig manure) applied in preceding crops on availability of nitrogen fertilizer was studied by the methods of pot and micro plot experiment in field, using the Isotope 15N trace technique.

为进一步促进烤烟轮作周期内有机肥和氮肥的合理施用，采用田间微区试验和田间小区试验相结合的方法，应用稳定性同位素15N示踪技术，研究了前作施用有机肥对烤烟氮肥效应的影响。

Traditional plastic injection molding machine relies on constant rate pump in oil supply, and each action in the process of plastic injection may have different requirements on speed and pressure. The surplus oil flows back to the oil tank through the proportioning valve in the way of flooding adjustment. In the whole process, the rotation speed of motor remains unchanged, so the oil volume is fixed as well. Furthermore, the action is intermittent, and not of full load, so a great amount of oil is wasted.

传统的注塑机是采用定量泵供油的，注塑过程的各个动作对速度、压力的要求也不一样，它是通过注塑机的比例阀采用溢流调节的方式将多余的油旁路流回油箱，在整个过程中，电机的转速是不变的，故供油量也是固定的，而由于执行动作是间隙性的，也并不可能是满负载的，因此定量供油就有很大的浪费空间。

Moreover, strong anisotropy is observed in the north and southcentral Tien Shan. Fast Pn velocity in the southcentral Tien Shan is nearly in NS directions, which is consistent with the SKS wave anisotropy concerning mantle flow. However, fast Pn velocity directions in the northcentral Tien Shan show a southward rotation variation. We estimate that it is probably related to the inserting of the crust of the Chu basin from the southern Kazakhstan platform to the central Tien Shan, which caused a change of stress fields and lithosphere deformation.

中天山北部和南部的各向异性也存在一定的差异，南部各向异性的快波方向为近南北方向，与SKS波的各向异性特征基本一致，反映了地幔物质的迁移方向；北部各向异性的快波方向呈向南凸出的旋转趋势，估计与哈萨克地台南缘楚河盆地地壳块体向天山挤入造成应力场的改变和岩石层变形有关。
