古老两河汇合香墅，地缘势能的悠远联想

We show that in the presence of high potential steps the Dirac equation has solutions which violate the principle of charge conservation. This paradoxical situation has no completely satisfactory physical explanation within a one particle interpretation.

我们证明在高势能步幅的情形下Dirac方程存在违返电荷守恒律的解，这种荒谬的结果没有任何令人满意的的物理解释在描述单个粒子的时候。

If the potential to be screened is denoted by , the energy of a charged particle of charge q in this potential is qφ.

如果被屏蔽的势能用φ来表示，则带电量为q的电荷在该电场中能量为qφ。

Finally, a closed form solution of additional displacements is obtained by the principle of minimum potential energy.

最后，应用最小势能原理确定位移幅值的闭合解。

Its territory resources are important conditions and physical foundations for economic development of the coastland.

海岸带作为海陆地理过程界面和国内与国外经济势能锋压，具有独特的区位条件和丰富的自然资源。

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。
