查询词典 congregative

In order to preserve the varieties of the swarm and avoid to be in premature convergence,a Particle Swarm Optimization algorithm based on the differential evolution mutation is proposed.The new algorithm uses the particle aggregation quality to judge that if the particles in the swarm are congregative so much,then apply the differential evolution to mutate the self prevenient best position of each particle,in order to realize the aim of preserving the varieties of the swarm.

为了保持粒子种群的多样性而避免发生&早熟&的问题，提出一种基于差异演化变异的粒子群优化算法，该方法通过粒子聚集性判断如果粒子群中的粒子过于聚集，则使用差异演化算法对PSO算法中各个粒子的自身历史最佳位置进行变异，以实现保持粒子群种群多样性的目的。

And there are two-part provinces in China whose congregative degrees of Broadcasting Industry are higher than the average level of countrywide.Because of the non negligible political and economical attribute of Broadcasting Industry, the general evaluation to it has to give attention to two aspects, both economical benefit and social benefit.

第9章通过建立广电产业综合竞争力指标体系，采用客观赋权法中的均方差方法，对中国31个省区2000和2004年的广电产业综合竞争力进行了评价，中国31个省级行政区广电产业综合竞争力的强弱差异十分明显，上海、浙江、广东、江苏和北京等省市优势明显，西部的贵州、甘肃等省则竞争力明显落后。

The results showed that the temporal-spatial distribution pattern did not alter basically from May 2002 to May 2006, and the topsoil congregative type of soil salinity profiles was the majority in the Yellow River Delta, which indicated that the risk of soil salinization was great, and the level of amelioration and rational utilization for saline soils needed to be improved further in the Yellow River Delta.

结果表明：从2002年到2006年，该地区土壤盐分剖面类型的空间分布格局基本没有改变，黄河三角洲土壤盐分剖面类型总体以表聚型为主，这表明黄河三角洲土壤盐渍化风险大，必须进一步提高盐渍土的治理和合理利用水平。

As for single dominant species commimity, either Halostachys caspica commimity or Haloxylon persicum commimity, the spatial pattern was all congregative pattern in 0~50m scale.

单优种盐穗木群落、白梭梭群落的优势种盐穗木和白梭梭在所研究的尺度(0～50m)上均为聚集分布。

The new algorithm uses the particle aggregation quality to judge that if the particles in the swarm are congregative so much,then apply the differential evolution to mutate the self prevenient best position of each particle,in order to realize the aim of preserving the varieties of the swarm.

该算法对于单调函数、严格凸或单峰函数，能在初始时很快向最优值行进，但在最优值附近收敛较慢。对于多峰函数，则更容易出现所谓&早熟&现象，即局部收敛[3]。粒子群算法出现&早熟&现象的主要原因是缺乏种群多样性。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
