空化水射流在本实验设备能达到的最高泵压条件下无法冲蚀破碎石灰岩，而对砂岩却表现出巨大的冲蚀能力。

The diapiric structures display various types such as a turtle-back-like arch, weak piercing, gas chimney, and fracture.

当富含甲烷气体的流体通过底辟构造、断裂及裂隙系统垂向或侧向运移时，在合适的温压条件下形成天然气水合物。

On the second and third plan, the quadrupler was made up of UMS's CHX-2089 and Minix's XX-1000 MMIC multiplier. The driver circuit's area still is very small. For two MMIC doublers, the driver circuit has only one input port of+12V.

In the upstroke, fluid pressure in the plunger acts on inner surface of expansion sleeve and makes it expand outward, keeping the seal ring press on the inner wall of pump barrel to form good sealing.

上行程时柱塞内部的流体压力作用到胶套内表面上使之向外膨胀，使密封环始终压在泵筒内壁上，形成良好的密封；下行程时弹性伸缩套恢复原状，柱塞和泵筒之间产生间隙。

In conjunction with the needle feed and the driven roller foot the double feeding of the wheel bottom feed ensures quiet and smooth sewing with exact stitch length, even when sewing over extremely thick spots.

下送布轮两步间歇式送布结合针送布和驱动滚轮压脚上送布确保了缝纫的静音和顺畅，并且即使在缝越极厚部位时亦能保证精确一致的针距长度。

According to the investigation of the rule of air flow at the stope, and applying the Technical method of the equal press fire prevention and pouring sand plasma, the author analyzed the feasibility of the exploitation under the fire area, and demonstrated it with examples.

通过对采场风流流动规律的研究，找出火区漏风源和漏风汇；应用均压防火和注浆堵漏技术措施，对火区下开采技术的可行性进行了系统分析，并举出成功实例加以论证。

"When the driver pushes down on the clutch pedal , the linkage forces a flat disk, or plate, to move. This movement releases the pressure from a friction disk."

当驾驶员踩下离合器踏板时，联动装置使离合器的压盘移动，这一运动减少了作用在摩擦盘上的压力。

It is showed that the propping fracture conductivity of gas log is 1.5 to 2.5 times higher than that of liquid log under the same testing conditions (such as haydite type, sanding concentration, temperature and pressure). A lower average sanding concentration in gas well fracturing should be adopted than that in oil well fracturing so as to obtain the same propping fracture conductivity.

结果显示，在相同实验条件下（陶粒类型、铺砂浓度、实验温度和压力），气测导流能力值比液测值高1.5~2.5倍，表明要获得相同的支撑裂缝导流能力，气井压裂中的铺砂浓度应比油藏低。

The garnet-pyroxene granulites in the area are located at the suture of subduction-collision orogeney between the North China and Yangtze plaleo-continents in the Northern Dabie.

本区石榴辉石麻粒岩，位于大别山北部，华北-扬子板块俯冲-碰撞结合部，根据上述岩石形成的温压条件，表明是在板块碰撞过程产生挤压，地壳增厚，高压麻粒岩相条件下形成的。
