In the functionally graded elastic half-space and the functionally graded covered layer, the motion control equations for the antiplane shear wave are solved, the analytical solutions for displacement and stress are obtained, and with these analytical solutions, the dispersion equation of Love wave is obtained.

对功能梯度弹性半空间和功能梯度覆层的反平面剪切波的运动控制方程进行了求解，给出了半空间和覆盖层的位移、应力解析解，给出了Love波在该解析解下的频散方程。

In this paper, the characteristics of supercritical fluid and principle of supercritical fluid extraction, gas anti-solvent, rapid expand supercritical solution were introduced. The development of supercritical fluid recystallization technology used in manipulating ultrafine explosives desired and SFE developed for demilitarization of energetic material and RESS technology used in coating of energetic material were reviewed.

摘 要：在阐述了超临界流体的性质和超临界萃取(Supercritical Fluid Extraction， SFE)、超临界流体溶液快速膨胀结晶（Rapid Expand Supercritical Solution， RESS）和气体反溶剂结晶（Gas Anti-solvent， GAS）过程原理的基础上，重点介绍了近年来超临界流体技术在含能材料细化，废弃炸药回收与利用，炸药包覆等方面所取得的研究进展。

The calculations indicate that Co should be inside of Ge〓, and bicapped tetragonal antiprism structure with D〓 symmetry is found to be the most stable structure of the cluster anion CoGe〓, which has the higher bonding energy and embedding energy.

激光双重烧蚀反应表明Co原子不在Ge〓团簇的外表面，量子化学计算表明，Co原子应在Ge〓团簇的内部，具有D〓对称性的双戴帽反四棱柱构型是幻数团簇离子CoGe〓势能面上的最低点，且具有较低的结合能和内包覆能。
