The author comes to some conclusions as follow: The Khanate of Kipchak kept the submissive relation to the house of the grand khan and supported the supreme khan of Mongol Empire in the inner politics and the policy to the outside, which gave certain supports to the early communication in the Mongol Yuan dynasty; The Khanate of Kipchak should account for the stop of the communication caused by the foundation of the Khanate of Ogotai which had been supported by the Khanate of Kipchak during the period of the reign from Berke to Mangu Timur; The short-time stop of the communication was also Mongolian central government"s tragedy. The relationships of the Khanate of Kipchak to Yuan dynasty began to become normal during the course of the reign of Tuda Mangu ,Tula-buqa and Toqatai khan, in which the Khanate of Kipchak gave certain devotions to "peace" of the Mongol Khanates. Their relations had been best after the separation of Mongol Empire during the time of ozbeg and Janibeg"s reign which was. the rush hour of our economic and cultural intercourses with the Khanate of Kipchak and other west countries. The development of the relationships to Egypt accelerated the intercourses between this two countries, which indirectly widened the ways of the Sino-Arab communication in the economy and cultures. The relations to Ire Khanate had been very bad for a long time. This stopped the convergence of the Steppe Silk Roads and the Oasis Silk Roads. In other side, this helped the intercourses between Ire Khanate and Christian Europe.

本文认为，蒙古帝国时期，无论在内政还是外交方面，钦察汗国都维护着蒙古大汗的权威，保持着与蒙古大汗廷的臣属关系，这为蒙元早期中西经济文化交流需要的条件做出了一定贡献；别儿哥至忙哥帖木儿统治时期，钦察汗国应对因窝阔台汗国的崛起而导致的中西交通的阻断负一定责任，但这同时也是蒙古中央政府的悲哀；脱脱蒙哥至脱脱统治时期，两国关系开始逐渐恢复，钦察汗国为蒙古诸汗国的&约和&贡献了自己的力量；月即别和札尼别统治时期是两国关系的最密切时期，也是双方经济文化交流和中西交通的高峰期；钦察汗国与埃及关系的发展，一定程度地拓宽了中阿经济文化交流的渠道；钦察汗国与伊利汗国关系恶化和长期的紧张，一方面阻碍了草原丝路与绿洲丝路的交汇，另一方面促进了伊利汗国与欧洲的经济文化交流。

So, this paper mainly focuses on the search capacity of intelligent algorithms, to improve their convergence speed and solution quality, and avoid them trapping in local optima. We study methods to enhance the global serach ability of an algorithm from the algorithm searching mechanism and spatial structure, and at the same time consider its lobal search ability.
