垒道

Firstly, within the framework of Di-Nuclear System Model, the formation probability of SHE by means of nucleons transfer after the formation of the DNS configuration is studied.

首先，我们在双核模型的框架内，研究了重离子核反应中能越过入射道位垒形成双核系统后，通过核子转移而生成复合核的几率。

So current increases. The increased current strengthens the space-charge effect further. So on and so on, the negative-resistance phenomenon occurs. For mathematical method limiting, SID's potential can't be solved outside channel or under middle, even big current.

对于SITH来说，由空间电荷效应所引起的阳极端场强增大现象导致空穴的抽出效应加剧，这部分抽出的空穴漂移至沟道中促使势垒降低从而加大了电流，而电流的加大又进一步加强了空间电荷效应，如此循环，造成了SITH特有的负阻转折现象。

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。
