查询词典 genetic code

It is difficult to insure globe convergence for regular BSS algorithms because they are easily trapped into local optimum, which can result in error of separation. This research associates genetic algorithm with traditional BSS and uses global optimize feature of genetic algorithm.

But whether the compound composed of them has suppressive effect on absence - like seizures of genetic tremor rats hasnt been reported. Furthermore, the animal models of investigating antiepileptic drugs were mostly induced by chemoconvulant or electrical stimulation. Since genetic factor is more primary in clinical epileptic patients, we used tremor rats fetched in from Japan as experimental animal models. We implanted electrodes in cortical and hippocampus of tremor rats and then recorded the electroencephalograms to observe effects of the traditional Chinese medicinal compound composed of Scolopendra, Bombyx Batryticatus, Uncaria and Arisacma Consanguineum on absence - like seizures in tremor rats.

而且以往多以化学致痫剂或电刺激等方法造模进行抗癫痫药物的研究，但在临床的癫痫患者中遗传因素占有相当大的比例，所以本实验应用了从日本引进的具有遗传性癫痫小发作的震颤大鼠作为实验动物模型，通过在震颤大鼠脑皮质和海马慢性安插电极后进行脑电图的记录，观察以蜈蚣、僵蚕、钩藤、制南星四味药为主的复方中药制剂对震颤大鼠癫痫小发作的抑制作用。

Finally, the parallel Genetic Algorithm is discussed and the parallel Genetic Algorithm for shortest route choice is given.

最后，本文还探讨了遗传算法并行计算的实现方式及其特点和适用范围，并选择了适用于最优路径计算的并行遗传算法。

We compare allelic frequency data among and between these drainages, analyze genetic relationships between trout populations found east and west of the Continental Divide, and compare the genetic diversity found among Sierra Madre trout and Mexican golden trout found in the headwaters of the Sinaloa and Culiacan drainages.

我们要比较数据之间的关系，这些等位基因频率渠、鳟种群之间的遗传关系进行分析，发现东西大陆鸿沟比较遗传多样性卞耀武塞拉MADRE向墨西哥金鳟、鳟发现夺了罗亚和利亚坎渠。

The faintest color of the bud color is yellow green. In addition, the variation-coefficient of some morphological traits is very low such as the cotyledon length, the cotyledon width, the cotyledon color, the silique length and so on. The Cluster analysis was based on the morphological data. When the genetic distance was 7.61, 21 accessions were clustered into 4 groups. The accessions of the group 1 had white petal, mezzo flower stalk and the earlier pick period, which is divided into two subgroup when the genetic distance was 5. 98. And the model was Ba39 and Ba35. The accessions in the group 2 had the very slender flower stalk and the middle pick period, that model was Ba27. The accessions of the group 3 had yellow petal, the thin flower stalk and the later pick period, that model was Ba43. The main characters of the group 4 were that it had the latest pick period and many leaves.

基于形态性状的聚类分析，在遗传距离7.61处，把21份芥蓝种质划分为4类，其中类群G1包括14份材料，其植株的生长势中等，株型较为一致，花瓣颜色均为白色，花薹粗细较为适中，平口时期较早，在遗传距离5.98处自然形成2个亚类，分别以Ba39和Ba35为代表；类群G2包括2份材料，即Ba27、Ba33，其植株的生长势较弱，花薹很细，平口时期相对居中，代表材料为Ba27；类群G3包括4份材料，即Ba05、Ba09、Ba38、Ba43，其植株的生长势较弱，子叶颜色、叶柄颜色、花茎颜色、花蕾颜色均为黄绿色，花瓣颜色为黄色，花薹较细，平口时期较晚，代表材料为Ba43；类群G4包括1份材料，即Ba41，其植株的生长势较强，平口时期很晚，并且叶片数很多。
