查询词典 acceleration of convergence

When processing the restrained conditions, we convert the restrained conditions into punish function and add it to fitness function which profits from the conventional method. We introduce the support vector machine to the selection operator, which increases the multiplicity of selection and increases the probability of the algorithm getting the overall optimal solution. Also, we use the adaptive probabilities of crossover and mutation in mixed GAs which enhances the efficiency of the algorithm. The result of tests about the system indicates that the improved genetic algorithm has more high convergence speed and better solution quality.

在生成初始种群时，不是简单的随机生成，而是用支持向量机对历史数据进行分类，用较优的一类历史数据作为初始种群；在约束条件的处理上，本文借鉴常规方法中的罚函数法，采用将约束条件作为罚函数包含到适应度评价中去的方法；在选择算子上，本文引入了支持向量机的方法，增加了选择的多样性，增加算法搜索到全局最优解的概率；同时针对交叉概率和变异概率在算法的前后期不同的情况，本文引入了Srinvivas等提出的动态自适应的方法，使得交叉概率和变异概率能够随着算法中个体的质量动态改变，提高算法的效率。

Thirdly, externality is an important factor to form industrial convergence. It can promote the forming of specialization victualer rank, especially providing the inputs which can not trade.

利用规模经济对集聚中心影响的估算方法，分析出影响中小型矿业企业集聚化中规模经济的因素不是运输成本，而是生产密度与集约化程度。3。

The APW in summer is less than 25 mm which is the least limit value of monsoon areas.This means that Xinjiang is not affected by monsoon.The geographic distribution of APW is adverse with that of precipitation,videlicet,higherAPW values corresponding to lower precipitation values.With the effects of westerly winds,the APW mode presents as an uniform change within Xinjiang area and has a stable distribution.It is very different from Xinjiang rainfall mode which changes a lot spatially.As mentioned above,there is no obvious change during 1961～2000,this indicates that APW is not a dominant factor determining precipitation,it is the result of dynamic condition,water vapor convergence and other causes.

APW的地理分布与实际降水量分布相反，其最大区域却为降水量最小区，受西风带影响，新疆APW模态主要表现全疆一致变化，分布稳定，与降水模态分布差异性大有显著不同，且近40年来无显著变化趋势，表明决定新疆降水差异的根本原因不在于水汽的多少，而是由降水产生的动力条件、水汽辐合和其它因素差异决定的。

The results indicated that the effect of deep warm-wet air coming along the behind subtropical high , moving eastward deepening upper trough , shear line and cyclone trough was caused in Zhuanghe , but no strong thunderstorm . The main impact of system is surface cyclone trough ; Low vortex , shear line in 700hPa , 850hPa strengthen the lower convergence , forming a strong momentum of increase and pieces of water vapor ; strong and wide potential pseudo-equivalent temperature frontal zone lied in Zhuanghe area , the establishment of potential instability are indispensable conditions for producing heavy rain .

结果表明：受副热带高压后部深厚的暖湿气流及西风带高空槽、切变线及气旋倒槽等动力系统共同影响，庄河地区出现了大暴雨天气，但没有出现强雷暴，此过程主要影响系统是地面气旋倒槽；700hPa、850hPa低涡、切变线使中低层辐合加强，形成了较强的动力抬升和水汽辐合；庄河地区处于强而宽的假相当位温锋区中，位势不稳定的建立是造成此次强降水的必要条件。
