First super-low specific-speed centrifugal pump has a long and narrow flow passage for its high head and low capacity, and the power absorbed by disc friction is too high, so the efficiency is very low; Secondly the diffusion of flow passage is so high, that the reserved flow often emerges at the inlet and outlet of impeller. Therefore the H ~ Q characteristic curve is often hump-shaped, and at the low-capacity operating condition the instability often occurs; Thirdly the centrifugal pump at high-capacity operating condition is easy to overload because the N ~ Q curve appears a rising trend.

首先由于它的扬程较高、流量较小，所以它的流道狭长，圆盘摩擦损失较大，效率相对较低；其次由于它的流道扩散较严重，易在叶片进口产生回流和在出口产生脱流，扬程流量特性曲线易出现驼峰，在小流量工况下易产生不稳定现象；第三，由于其功率流量曲线呈现上升趋势，在大流量区运行时电机易过载。

The shockwave of the meteorite strike on the terrane of the surface passes the dynamic energy to the surface and forms the target terrane shatter cone; due to the fact that the terrane of stricken surface can not maintain the state of stress, a cluster of rarefaction wave was formed behind the shockwave to decompress terrane substances from high pressure state, this cluster of rarefaction wave ejects with high speed from the interface between the substances such as meteorite, surface terrane and lava, the shockwave compresses the target terrane substances, generating super-high temperature and forming a jet current of rock mass, rock powder, lava or rock fog with high pressure and temperature, the jet current lasted until the shockwave rebounded from the backside of rock, and the target of meteorite-stricken surface is formed on surface.

陨石撞击地面岩层时的冲击波把动能传给地表产生靶岩震裂锥，由于被撞击地表岩层不能维持应力状态，冲击波后面就发展一簇稀疏波使岩层物质从高压状态下减压，在陨石、地表岩层、熔岩等物质交界处高速喷出，冲击波压缩靶点岩层物质产生超高温，成为压力大温度高的岩块、岩粉、熔岩或岩雾喷射流，直到冲击波从岩石背侧反射、地面上形成陨击靶点。
