For the kobold horizontal - axis rotor , the hydrodynamic performance is explored and studied gradually . at first , a basic resistance - type method is presented 对于横轴蹼板式水轮机，本文从流体力学的基本原理出发，对蹼板式水轮机的水动力性能及其计算方法进行了循序渐进的探索和研究。
5 mast can be fixed on staging immediately without drill frame with auxiliary parts horizontal axle and buckles , which makes it possible for greatly reducing rig weight and fast moving 5钻机桅杆上预留固定安装孔，可以无需机架直接通过辅件横轴及扣件安装在脚手架上，使重量大大减轻，移机快捷方便。

The main reason of the stepped spillway having greater energy dissipation is tha there is big horizontal vortex in the inner angel of the steps and it makes momenbo exchange with outer mainstream then accelerates the theulence in the water 由于阶梯的存在，使得水流在阶梯凹角内产生强烈的水平横轴旋涡，旋滚水流与外部主流之间不断进行的动量交换加剧了水流内部的紊动，从而使阶梯溢流坝有较高的消能率。
Ultrasonic bio - instrumentation has several display modes used in medicinal field now , such as b - mode and m - mode , etc . b - mode uses the modulated brightness to represent the amplitudes of ultrasonic echoes , and the coordinates in the formed profiles correspond to positions of ultrasonic beam scans one by one B型显示是用亮度调制来显示回波脉冲幅度，显示的横轴和纵轴与声束扫描的位置一一对应，形成超声切面图像。
The straight transverse axis shall be parallel with the present crooked jianshe avenue ( qingnian road - hanxi section ) , connect to nanniwan avenue in the west and form the along - river traffic system parallel to yangtze river and hanjiang river ; the road shall pass through the core of wangjiadun cbd , connect with entry and exit of subway station , underground parking lot and basements of high - rise buildings , to form the comprehensive underground space ; the road section close to hanxi shall be connected to the tunnel of nanniwan avenue via through cut , therefore integrating the western residential zone in space 横轴对建设大道（青年路-汉西段）裁弯取直，西与南泥湾大道相接，形成与长江、汉水平行的顺江交通系统；该道路贯穿王家墩商务核心区，与地铁出入站、地下停车库以及高层建筑地下层相衔接，形成综合地下空间；靠近汉西路段以路堑形式与南泥湾大道隧道相接，在空间上使西部居住区形成整体。
Base on the model founded , this paper assessed the ride performance by analyzed the root mean square value of power spectral density of acceleration of z - axis and round y - axis rotation acceleration at the driver ’ s seat . the root mean square value of suspension working spaces and dynamic tyre loads were also analyzed . base on the assessing system of vehicle ride performance , the root mean square 根据模型建立的实际情况,对车辆标准载荷情况下的平顺性指标进行了计算,对人体感受到的振动采用了垂直方向和绕横轴转动方向的加权振级来评价,计算了车辆悬架系统的动挠度均方根值和各车轮相对动载荷均方根值的情况,全面的评价了车型的平顺性。
On the foundation of theoretical analysis , this paper combines the condition of economic and nature of baoding hebei province to concept the landscape ecological program frame . in order to vague the limit of city center and village . the main planning idea is to establish a central ecological forest x - axis and eastern wetly tourist landscape district as well as water network and traffic line landscape ecosystem for the open town and country ecology system 在理论分析的基础上，本文结合保定市的自然、经济状况，构想了保定市景观生态规划框架，规划目的是模糊城市中心与乡村的界限，构想建立一个以西部绿色屏障林带、中部特色农业带和景观城市带为中心的生态纵轴、东部湿地旅游景观区以及环形河网和交通线为横轴的开放式的城乡融合景观生态系统。
