This paper presents the effect of tail sting and the angle of boat tail on the base pressure at supersonic velocities. 本文介绍了天平尾支杆以及模型船尾(BT)对超声这弹丸底压测量影响的实验研究和理论计算。
The experimental investigation and analysis about the effects of tail sting and boat tail on the base pressure of projectiles at supersonic 支杆及船尾(BT)对超声速弹丸底压影响的实验研究和理论计算
The measures were indicated that increase waterpower machine and accretion water velocity of flow in boat bottom and tail, and laminose overfall drainage water become trapezia. 提出通过增加水力机械,增大船底水流速,进而增大船尾(BT)进水流速,并将船出水平流堰改进为梯形溢流堰等措施,提高船式沉淀器的处理效果。
Cox is a boy or a girl who is the driver of the boat, all the oar men face to the tail of boat and only the cox face to the head of boat. 舵手是控制赛艇方向的人,因为所有的桨手都面向船尾(BT),只有舵手是面对船首的。
Since the line is around the head, rescuers would approach the whale in a small inflatable boat at its most perilous spot, easy targets for the tail. 由于钓线缠绕在鲸鱼的头部,拯救人员将乘坐充气艇靠近鲸鱼的头部。而鲸鱼的头部通常是最危险的部位,因为这里经常是鲸尾袭击的对象。
