The truth was exactly the other way round: it was the Soviet secret police who organised ruthless repatriations, often dividing families.

事实恰恰相反：正是苏联秘密警察残酷地强制流散到苏联境外的人返回苏联，常常导致一家人骨肉分离。

When the mobile phase composition on the current step is optimized, the overlapping separation range map for solutes eluted in next one or two steps is replotted simultaneously by considering the influence of elution conditions for current step on the retention of uneluted solutes.

在对当前台阶流动相组成进行优化的同时，考虑其对后面一到两个台阶上流出组分保留的影响，实时地重新绘制对于后面台阶上流出组分的重叠分离区域图。

Vascular endothelial cell growth factoris a kind of glucoprotein ,which has separated by culturing stellate cells of bovine glandula pituitaria in vitro by Ferrara etc. in 1989.lt can express that anxo-act vascular endothelial cell growth specificly and induce vasotropic growth ,so it is called VEGF.

血管内皮细胞生长因子(Vascular endothelial cell growth factor)是1989年Ferrara等牛垂体星状细胞体外培养分离出的一种糖蛋白，其在体内外都表现出特异性地促进血管内皮细胞的生长并诱导血管生成作用，故此称为血管内皮细胞生长因子。

A simple, reliable and reproducible method, capillary electrophoresis with amperometric detection, for separation and determination of the active ingredients in tablets of the composite sulphonamides was stated here.

运用毛细管电泳-安培检测法首次成功地建立了对三种复方磺胺类药物中有效成分同时进行分离分析测定的方法，获得了令人满意的结果。

Moreover,the array considered here can be of arbitrary geometry and even uncalibrated.

理论分析与仿真结果表明，该方法能够有效地进行阵列响应估计和信号分离，在空分多址的实现方面具有较强的实用性。

For images rendering under novel lighting conditions, direct illumination effect is calculated using lambertain model; while indirect illumination one was added by environment light part derived before.

新光照条件下场景的绘制，直接光照采用光照模型直接计算；间接光照采用分离出的基图像环境光分量拟合，较好地实现了变化光照下场景图像的生成。

The circumlunar satellite separated from the rocket at 6:29 pm and entered into Earth orbit, where it will travel for seven days, according to the Beijing Aerospace Control Center.

据北京航空控制中心宣布，&嫦娥一号&绕月卫星于下午6：29分与运载火箭分离并进入绕地轨道，且将绕地球七天。

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。
