Then considering earth rotation and 6-DOF movement,the expression of absolute velocity and absolute acceleration for vehicle centroid are deduced by using transform of vector derivative.

与陆基固定垂直发射条件不同的是，潜射弹道式飞行器是在运动着的潜艇这样的动基座上进行发射的，为了保持发射时潜艇的可操纵性以及发射后使发射艇尽快离开发射位置，发射艇要有一定的速度。

By simulating the flows over a series of submarine models, which are created by our mathematical method through changing the parameters of hull form, the viscous resistances of these submarine models can be predicted, so"submarine viscous resistance numerical test tank"can be founded.

运用我们提出的实用艇型自动生成程序，变化相关的艇型参数，建立系列艇型，通过数值计算，得到这些艇型的水下阻力系数，初步建立了"潜艇水下阻力数值试验水池"。

World War II expansion programs led to construction of two large groups of subchasers, the new 110-foot wooden-hulled craft and the 173-foot steel-hulled type. By 1943, it was felt desirable to differentiate between the two types. The type symbol PC was retained for the steel 173-footers, and the separate symbol SC was adopted for the 110-foot vessels.

根据二战舰队扩充计划开始建造两个型号的猎潜艇，新110尺木制艇和173尺钢制艇。1943年海军觉得应该对两型艇加以区分。173尺钢制艇保留PC编号系统，而单独的SC编号系统被分配给新110尺木制艇。

The effect of bubbly layer on propulsion performance of planing craft is investigated by means of self- propelled model experiment in the towing tank of China Ship Scientific Research Center.The results show that bubbly layer has small effect on propulsion performance of planing craft model propelled by water skew propeller.

在中国船舶科学研究中心拖曳水池中，通过滑行艇模型自航试验，研究了艇底气层对滑行艇推进性能的影响，结果表明：气层对采用水螺旋桨推进的滑行艇推进性能的影响不大。
