查询词典 isolate

At the early iteratives, the mutation rate is bigger and the aim is to make particles to explore smaller and isolate region and to avoid the algorithm trapping to the local optimum. While the algorithm runs, the mutation rate will be decreased to reduce the disturbing to the particles. IPSO adopts a new method that congregates some neighboring individuals to form multiple sub-populations in order to lead particles to explore new search space. Additionally, our algorithm incorporates a mechanism with a simple and easy penalty function based on the largest distance between the particle and the boundary of the feasible region to handle constraint.

IPSO采用了一种新型的变异策略，变异概率随着算法的运行是动态变化的：在算法运行初期，变异概率大，其目的是使算法不但能够探测到目标空间中的孤立区域，而且避免搜索陷入局部极值；在算法运行后期，变异概率逐渐变小，以减少对粒子的扰动；算法通过将部分具有邻近距离的粒子聚集成核形成多子群引导种群中粒子的飞行；采用一个简单的基于粒子与可行域边界最远距离的罚函数处理约束的机制，使得算法高效实现。

In this paper the resistance of Fulvia fulva to flusilazole, inducing resistance of sensitive isolates, biological characteristics of mutant-isolate and cross-resistance to other fungicides were studied. The level and distribution of F.fulva resistance in Liaoning, the fitness of mutants, the relation of cross-resistance between flusilazole and other fungicides were confirmed.

本试验系统地研究了目前辽宁省主要保护地蔬菜种植区的番茄叶霉病菌对杀菌剂氟硅唑的抗药性现状、敏感菌株抗药性诱导、抗药性菌株生物学特性以及与其它药剂的交互抗药性关系。

Humidification of the workshop is to shop humidity environment to a more appropriate range, so that static electricity generated by the basis of the loss is to prevent static electricity from the fundamental (but note that: For a number of insulators to isolate the generation of static electricity, a single means of humidification not a good solution of the static problem, the need for the joint effect of a variety of ways).

对车间加湿是将车间环境湿度提高到一个较为合适的范围，使静电失去产生的基础，是从根本上防止静电（但需要注意的是：对于一些孤立的绝缘体所产生的静电，单一的加湿手段并不能很好的解决其静电问题的，需要多种方式共同作用）。

The progress of the cell cycle of Spodoptera frgiperda IPLB-Sf21-AE clonal isolate 9 (Sf9) cells was directed by Flow cytometry analysis.The results showed that the whole time of the cell cycle was about 18 hours and the gapes between every two phases were about 6 hours.At 12-18 hours post AcNPV infection,Sf9 cells were arrested in G\-2/M phase.When the cells in G\-1/S phase synchronized by druge were infected by AcNPV,2/3 of the cells was in G\-2/M phase and 1/3 of the cells in S phase.

应用流式细胞仪FACS的荧光检测，测出Sf9细胞完成整个周期循环大约需要 18h ，G1、S、G2 /M各时相的时间间隔约为 6h ；AcNPV感染Sf9细胞 12 18h ，细胞被抑制于G2 /M期；Sf9细胞同步于G1/S期后释放细胞并用AcNPV感染，12h后，2 / 3的细胞处于G2 /M期，1/ 3的细胞处于S期

Methods:Via a cannula iserted into adominal aorta, Gey's balanced salt solution containing 0.025% collagenase P was perfused into rat normal pancreas. After digestion with collagenase P and protease, Nycodenz density gradient centrifugation was performed to isolate PSC. PSC was identified by its morphology, cytoplasmic lipid droplets and immunocytochemical staining for desmin, GFAP and α-SMA. Results:The production,viability and purity of isolated PSC were（15.3 ± 4.6）× 103／g body weight,（95.0 ± 3.5）%, and ﹥80％ respectively.
