有分离的

Modern systems consist of one or more computer-controlled metering pumps that can be programmed to vary the ratio of mobile phase components, as is required for gradient chromatography, or to mix isocratic mobile phases (i.e., mobile phases having a fixed ratio of solvents).

后者有一个装样品瓶的转盘或者架子，瓶子顶部用可以穿孔的隔膜或者塞子密封，和一个注射装置来把样品从样品瓶转移到定量环，从那里注入到色谱分离系统。

Polymers in practical applications are inevitably polydisperse.

实际应用的高分(来源：ABC论文9494网www.abclunwen.com)子难免具有分子量的分散性，分子量分散性对成核相分离有什么影响却还不清楚。

Cognitive behavior of the grown-up offspring that the clozapine-exposed in pregnance lead to the the retardation of the weight of filial rats in earlier age.

体格生长：子代大鼠出生后第4天和第7天，对照组和用药组大鼠的体重差异有显著性(F=12.56，P＜0.01；F=7.51，P＜0.01)11，17天则没有差别，显示氯氮平孕期给药可导致子代大鼠早期的体重增长迟缓；孕期使用氯氮平对子代大鼠耳廓分离，出牙时间，开眼时间没有影响。

Twenty-eight prototrophic revertants of the tryptophan auxotrophs were obtained through spotaneous back mutation from colonies grown on synthetic medium plates or nodules of plants. Most of the revertants have resumed the nodulation abilities and enhanced nitrogen fixation activities as evidenced by darker green color, higher dry weight and more nitrogen contents in shoot than those of the wild type strain 8-1-4A did in pot experiments. However, noodulation abilities decreased to some extent and no significant differences were found in the mass of nodules compared with the parent strain.

通过自发回复突变，从培养平板和根瘤中分离到28个色氨酸原养回复突变型菌株，对其中25株进行植物盆栽试验证明其中24株菌的结瘤功能得到了恢复，而且固氮酶活性普遍比出发菌有所提高，其中41％达到极显著水平，18％达到显著水平，植株地上部分干重及含氮量也有不同程度的提高，唯有根瘤数比出发菌有所降低，其中23％降低达极显著水平，11％降低达显著水平。
