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。

There are five types of deformational structure in the front zone of the Tang－Lun nappe, Ningzhen Mountain:great rotating of beds and imbricated system;reversed structure;transverse and oblique faults with the character of tear faults;warping of recumbent folds and kink band with advantageous shearing direction.

发育在宁镇山脉的汤―仑推覆体前锋带上的变形构造存在五种型式：岩层的大幅度旋转与密集的叠瓦系；反冲构造；具捩断层性质的横向及斜向断层；平卧褶曲的翘起和具优选剪切方位的膝折构造。

How long will you go about, O you backsliding daughter?

022 背道的民哪，你反来覆去要到几时呢？

And I am full of tossings to and fro unto the dawning of the day.

我躺卧的时候便说：我何时起来，黑夜就过去呢？我尽是反来覆去，直到天亮。

And I am full of tossings to and fro unto the dawning of the day.

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
