The main reason is that the condition ismore complicated in open field,and measuring result is much more easily influenced bysome kinds of clutters,like atmosphere attenuation,cloud or fog,the fluctuating of scaleobject and ground clutter and so on.So these factors should be taken into account inpractical measuring,and make some amending processing.

主要原因是外场中情况复杂，测量结果受各种杂波影响较大，如大气衰减、云或雾、定标金属球的波动、地面杂波等，因此在实际测量中应考虑这些因素，并做出相应的修正处理。

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。

The evolution process of nocturnal radiation fogs and lower stratocumulus and their effects on the boundary layer structure are studied with the calculation of a model.
