The lens axicon is based on the use of the spherical aberration of the mirror surfaces,which is inexpensive and easy to manufacture into a element with large apertures as compared with diffractive axicons,refractive cone axicons,and earlier lens axicons with aspheric surfaces;the opaque disk can offer the Bessel beams with long non-diffracting distances,and the diameter of the central peak is adjusted by choosing the focal length of the collimating lens;the tunable fluidic conical lens is a new device for generating Bessel beams,which can obtain the Bessel beams with different parameters by varying the refractive indexes of the solution which is filled in the device.

双透镜轴棱锥法主要基于透镜球面像差的运用,与衍射轴棱锥、折射轴棱锥和早期的非球面轴棱锥相比,具有加工简单、便宜,易于制作大尺寸的特点;不透明障碍物法得到的贝塞尔光束具有很长的无衍射距离,其直径可通过选择不同焦距的准直透镜来得到调节;可调流体轴棱锥是一种产生贝塞尔光束的新型器件,它可以很容易地通过改变注入器件的液体的折射率来得到不同参量的贝塞尔光束。

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。
