Weak formulation of mixed state equations including boundary conditions are presented in a cylindrical coordinate system by introducing Hellinger_Reissner variational principle.

从Hellinger_Reissner变分原理出发，在柱坐标系中，导出圆柱壳的弱形式混合状态方程和边界条件，联用状态空间法给出叠层柱壳的解析解，此法使得求解该类问题的形式得以扩大和统一。

And for a long-range weak interaction or stiff material, another limiting form is corresponding to a generalized DMT model.

它在强吸附或软材料条件下的极限形式是广义JKR模型，而在弱吸附或硬材料下的另一个极限形式是广义DMT模型。

Due to the moving base existence of the minehunting and the frame structure characteristic of the sonar array, a new modeling thought in which the boat body coordinates is regarded as moving coordinates and the whirligig equation of sonar array compared with the self coordinates is founded on the basis of the Euler's theorem and the coordinate transform is introduced.

由于猎雷艇作为动基座的存在和声纳基阵的框架结构特点，提出了以艇体坐标系为运动坐标系，运用变形的欧拉定理和坐标变换建立声纳基阵相对自身坐标系的旋转运动方程的建模思想；将所建立的矢量形式的动力学模型展开整理，获得了状态矩阵形式的猎雷声纳基阵动力学方程，为系统动力学模型的实用化奠定了基础。

The dynamic equations of minehunting sonar array with the state matrix form are founded by settling the dynamic models with the vector form. So it offers theory foundation for analyzing the dynamic characteristic and designing robust control.

Therefore in Old English we have the following names (with their Modern English developments): Sunnandg, Sunday; Mnandg, Monday; Twesdg, Tuesday (the god Tiu, like Mars, was a god of war); Wdnesdg, Wednesday (the god Woden, like Mercury, was quick and eloquent); Thunresdg, Thursday (the god Thunor in Old English or Thor in Old Norse, like Jupiter, was lord of the sky; Old Norse Thrsdagr influenced the English form); Frgedg, Friday (the goddess Frigg, like Venus, was the goddess of love); and Saeternesdg, Saturday.

所以在古英语中我们看到以下的名字（以及他们的现代英语形式）： Sunnanhd？g，星期日； Monand？g，星期一； Tiwesd？g，星期二（蒂乌神，象玛尔斯一样，是战神）； Wodnesd？g，星期三（沃登，象墨丘利一样，行动敏捷，善于词辩）； Thunresd？g，星期四古英语中的撒纳及古挪威语的索，象朱庇特一样，是宇宙之主；古挪威语的 Thorsdagr影响了英语中的该词的形式）； Friged？g，星期五（女神弗丽嘉，象维纳斯一样，是爱神）；和 Saeternesd？g，星期六

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。
