Especially in the processes of frost heave and formation of ice, the function of stress is greatly important.

尤其在土体的冻胀变形和分凝冰的形成过程中，冻胀应力对冻土地区结构物具有不容忽视的影响。

First, some critical problems in crystal growth like crystal seeding, Zn dephlegmation, geometrical selection and temperature fields are discussed in theory, and the possible kinds of defects appeared in crystal growth progress and the reasons are carefully researched. To control the concentration of Cd vacancies, a new method by which the Cd vacancies were compensated with excess Cd in the Cd rich starting materials has been developed, and a new kind of two-area tube furnace with good linear temperature distribution was designed.

The absorption results indicated that the Co ions presented +2 valence in crystal and located within the distorted oxygen octahedrons.

从吸收特性表明，Co离子掺杂于畸变的氧八面体中，呈现+2价态，并且沿着晶体生长方向浓度逐渐减少，Co2+在LiNbO3晶体中的有效分凝系数大于1。

On the basis of experiments, the mechanism of phosphorus gettering for crystalline sili...

这表明：磷吸杂主要是与过渡族金属的溶解、扩散和分凝有关。

The optimized process was found to exist when using constant temperature phosphorous gettering to fabricate crystalline silicon solar cells, which suggests that phosphorous gettering effect depends strongly on the dislocation, diffusion as well as the segregation of transitional metals.

这表明：磷吸杂主要是与过渡族金属的溶解、扩散和分凝有关。连续变温磷吸杂的效果要明显优于恒温吸杂，特别是在原生多晶硅中的高质量区域。

Our model explains why segregation mainly occurs at particular levels and produces distinctive magmas.

我们的棋式说明了为什么分凝作用主要发生在特定的深度和产生的性质不同的岩浆。

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。
