“ this afternoon the session wasn ' t massive , it was just to get used to the pitch and the ball because we have trained with the premiership ball 今天下午的训练任务并不多,主要是适应一下场地和球,因为我们一直用的是英超的皮球。
The results indicated that low graphite spheroidization rate and free cementite were the main causes of poor mechanical property 试验结果表明,控制碳当量和球化剂加入量,采用瞬时孕育等可提高球化率;采用预热砂型等可减少渗碳体。
Points within the sphere are assigned values based on their position between the center and the boundary of the sphere by the network of upstream nodes 在球上的点是基于它们的位置来赋予数值在中心和球的边界通过材质网络的上游节点。
In this equation , r represents the position of the ball , with r0 being the initial position ; and v represents the velocity of the ball 为了发现球和球之间或者球与台子边框之间的碰撞,我用这条线的矢量方程来描述假定球在假定时间的位置。
The rayleigh - taylor ( rt ) instability in cylindrical and spherical geometries was analized in this thesis , based upon velocity potential theory 本论文利用速度势理论对柱和球几何中不可压缩流体的rayleigh - taylor ( rt )不稳定性进行了研究。
The influence of legs " tolerance and spherical joints " ( huke joints ) clearance on errors of terminal platform is analyzed using monte - carlo technique 利用蒙特卡洛技术模拟分析了驱动杆杆长误差和球铰(虎克铰)间隙对终端平台误差的影响。
Many cities have public tennis courts , so you don t have to be an aristocrat to afford the game . you will , however , have to shell out for rackets and balls 许多城市都有公共网球场,所以你不必拥有贵族身份就打得起,不过,你得自掏腰包买球拍和球。
At the early stage of establishment , a range of rangers - themed , leisurewear and accessories will be launched in the market to serve the club ' s beloved supporters 创馆初期,一系列以流浪为主题的舒适休娴服装和球会精品将会首先推出市场,向一众广大球迷见面。
Features a modular design concept which facilitates maintenance and assembly access . all sizes are standardly equipped with gate valves and ball type test cocks 模块化结构的特点在于简化维护,有助于总成的接近。作为标准配置,所有通径都配置闸阀和球型测试旋塞。
Then the cnts were purified by nitric acid and shortened by ball milling . the microstructure of carbon nanotubes was observed using transmission electron microscope ( tem ) 利用化学气相沉积法( cvd )制备了多壁纳米碳管( cnts ) ,并对纳米碳管进行纯化和球磨的处理。
