At the same time , in the base of that the research of movement system 、 force system 、 sustain system 、 lubricate system 、 pressurize system 、 adjust of rotate speed system and so on . manufacture a experimentation equipment of hyperboloid clutch with rollers . find the relation between force of outer race and movement of inner race 同时,通过对转矩系统、轴向力加载系统、支撑系统、润滑系统、密封系统、转速调节系统、电压测试系统、电流测试系统的研制,研制出了一种对加载器力学性能进行测试验证的实验装置。
Taking gis software ( arc / info and arcview ) and visual foxpro as basic plat , protracted the system maps of land resource , those basic subject maps included land use status map , land types map , soil types map , grade map and soil organic substance map , combing with former summarizing research results , built the spatial basic database of land resource ; based the spatial database , by the means of attribute table manipulation and take the map plot as basic unit to get the subject attributes of basic information , combined with social economy attribute information , built the attribute database ; take the spatial basic database as basic work , by the means of vector piles to get the land resource dynamic movement system maps , included land use status , land types and soil organic substance dynamic movement map 以gis软件( arc info 、 arcview )与visualfoxpro为基础平台,绘制完成土地资源的系列图,包括土地利用图、土地类型图、土壤类型图、坡度图、土壤有机质图等基础专题图件,结合以前的工作成果,构筑土地资源的空间本底数据库;通过空间叠加分析,得到基础单元图斑,采用属性表操作的方法获取基础单元图斑的专题属性信息,结合社会经济属性信息,建立属性数据库;以空间本底数据库为基础,采用矢量叠加对比分析的方法,得到土地资源动态变化系列图,包括土地利用、土地类型、土壤有机质等动态变化图。
The authors studied the rules of all previous martial art competitions and analyzed the characteristics and contents of evolution of the rules , and drew the following conclusions : 1 ) technical structure of the movements has changed as a result of technical guidance , which , however , has a tendency to deviate from the nature of such a sport ; 2 ) the gradual establishment of difficulty movement system has raised the level of standardization of judgment criteria ; 3 ) the development of performance techniques has enhanced the appearance of the movements and increased the difficulty of the techniques ; 4 ) the evolution is lack of guidance for offense and defense consciousness as well as intrinsic spirit , and neglects technical style 摘要对历次武术竞赛规则进行了研究,分析规则演变的特点和主要内容,认为: ( 1 )对技术导向影响到动作技术结构变化,但有偏离本质的倾向; ( 2 )难度动作体系逐步建立,提高了评判规范程度; ( 3 )演练技巧的发展提高了动作外在形象和技巧难度; ( 4 )缺乏攻防意识和内在精神导向,忽视技术风格。
