It was widely accepted that the spall slapdown is the primary contributor to the non-spherical source process of underground explosions. Previous studies on its mechanism are usually based on surface waves. In this article, body waves are analyzed us

The generation mechanism of Lg wave from underground nuclear explosion is still not clear at present. The general viewpoint is that the S wave generated by the near-source scattering of explosion-generated Rg appears to be the primary contributor to

It was widely accepted that the near-source scattering of explosion-generated Rg into S is the primary contributor to the low-frequency Lg from nuclear explosions, because the prominent low-frequency spectral null in Lg coincides with that in Rg from

Near-source scattering of explosion-generated Rg wave into S wave appears to be the primary contribution to the low-frequency Lg wave in nuclear explosions, this mechanism has been supported by analysis of regional data from several Yucca Flats, NTS

The polaron confined in a GaAs film deposited on Al0.3Ga0.7As substrate are investigated by using the framework of the fractional-dimensional space approach. The numerical results for the polaron binding energy and effective mass as functions of the

The dehydration of bischofite is the key to the use of magnesium resource. Double salts or complex method is an important way to prepare anhydrous magnesium chloride. The crystals of bischofite and aniline hydrochloride were prepared through lowering
