Since then , and despite efforts to cut emissions , the concentration of these gases in the atmosphere has increased to a level where some degree of dangerous climate change is now inevitable and unavoidable , at least in the next couple of decades for some countries , ecosystems and communities 此后，尽管人们致力于减少排放废气，但是在大气层中这些气体的密集度已经提升至了某一水平，就是说在某种程度上的具有危害性的气候变化，现如今是无可避免也无法避免的了，至少在接下来的几十年里，对于某些国家，某些生态系统，某些社区而言会是这样的。
In the next place , the paper introduces risk - degree of collision which is defined using distance and relative orientation between the mobile robot and obstacles , and then plans the path using the method based on risk - degree of collision and fuzzy logic control . the obstacle - avoidance simulation is carried out , the results indicate that the method is feasible . thirdly , in the multi - mobile - robots system , the robots are considered as moving obstacles between each other 在总结了前人对路径规划的研究和船舶避碰研究的基础上，形成了机器人碰撞危险度的概念，并给出了相应的数学描述，在采用模糊逻辑方法时，用障碍密集度来对模糊规则进行修改，并在基于机器人碰撞危险度和模糊逻辑的基础上进行了移动机器人路径规划的研究，通过仿真分析，表明该方法是可行的。
The second part is the core of this paper . firstly , the author analyzed and appraised the international competitive power of china ' s textile industry from four aspects of competitive ability , competitive potential , competitive strength , competitive circumstances , concluded four conclusion : the international competitive power of china ' s textile industry still had some advantages , the advantages inclined to weaken , the international competitive power of branch industries was in equable , the advantages was gained by the increasing quantity of production and export ; secondly , on the basis of the above analysis , the author analyzed the factors affecting the international competitive power of china ' s textile industry ; at last , the author analyzed the impact of china ' s joining wto on the international competitive power of china ' s textile industry . in the last part , on the basis of the above analysis and research , the author gave some advice on maintaining and improving the international competitive power of china ' s textile industry 第二部分，这一部分是全文的核心部分，首先从竞争能力、竞争潜力、竞争实力、竞争环境四个方面来综合分析和评价我国纺织业的国际竞争力，得出我国纺织业目前在世界仍然具有较强的国际竞争力、我国纺织业各分行业国际竞争力水平是不平衡的、我国纺织业的国际竞争力存在弱化的趋势、我国纺织业国际竞争力主要是靠粗放型增长获得的四个结论；然后在此基础上从定性和定量两个角度来分析影响我国纺织业国际竞争力的因素，指出资本密集度提高、棉花流通体制改革、规模经济扩大等因素促进我国纺织业国际竞争力的提高，科技创新不足、国内市场竞争不足、环保问题以及亚洲金融危机等因素阻碍我国纺织业国际力的提高；最后再分析加入wto对我国纺织业国际竞争力的影响，总的来说是利大于弊，分为对纺织业总体国际竞争力的影响和对纺织业内各分行业国际竞争力的影响。
But after world war ii . especially in the recent 30 years , intra - industry trade which means the mutual trade of same kind products between developed countries flourished . furthermore , the trend that intra - industry trade would replace inter - industry trade and become the mainstream of world trade can be seen , which could not be explained by traditional trade theory 但二战以后特别是20世纪70年代以来，发达国家间这种要素密集度相似的货物的双向贸易? ?产业内贸易的发展非常迅速，有取代产业间贸易而成为世界贸易主流的趋势，这显然是传统的国际贸易理论不能解释的了。
Based on observed sea ice concentration data and simulated results , there has been noticeable downward trend in the extent of arctic sea ice during 1979 - 1998 . the model shows a substantial reduction of ice advection into the eastern arctic from the canada basin , and an increase of ice export through fram strait , both of which tend to deplete the sea ice of arctic 模拟结果表明北极海冰有很明显的季节变化和年际变化，实测的海冰密集度资料和模式模拟结果都证明1979 - 1998这20年间北极海冰的一个最明显的变化是海冰在不断减少。
Methods to calculate effect of bias error and dispersion on first - round hitting probability and on multi - round hit probability are discussed . according to calculating results , influence on first - round hitting probability by accuracy of each factor , by the firing range , by the change of meteorology condition with space - time , and by dispersion are analyzed , so are influence on multi - round hitting probability by bias error & dispersion 讨论了射击开始诸元精度与密集度对首发命中概率与多发命中概率影响的计算方法，并根据计算结果讨论了决定射击开始诸元的各因素精度、射程的变化、气象条件随时间与空间的变化对首发命中概率的影响，密集度的变化对首发命中概率的影响，及射击开始诸元精度与密集度对多发命中概率的影响。
This thesis present the systematic studies on firing accuracy and firing accuracy tactical & technical requirement reasoning for gunnery system . the main contents of the paper are as follows . ( 1 ) definitions and probability distribution expressions for error of fire , error of firing data and error of dispersion are given summarily . methods to compose error of initial firing data and error of dispersion are discussed 本文对远程炮武器系统射击精度及射击精度战术技术指标论证等方面问题进行了深入、系统的分析研究，本文研究工作的主要内容有： ( 1 )概要地讨论了射击误差、诸元误差、散布误差的定义及其概率分布，诸元误差、散布误差及射击误差的合成，分析了射击精度的各种表示法，阐述了火炮武器系统准确度、密集度和首发命中概率的估算方法。
