“雷德飞潜艇”(RFS-1)是典型的混血儿,它是雷德在业余时间里用其他飞机的零碎部件拼凑成的,正如尤沙科夫的设想一样,它是一架浮力飞行器。
The Reid Flying Submarine (RFS-1) was a true mongrel, constructed by Reid in his spare time using leftover parts from other aircraft and, like Ushakov's design, it was a floatplane.
然后,根据波浪中重力与浮力平衡、纵倾力矩之和为零这两个条件来求取横摇稳性力臂值。
Finally, the values of roll stability, in accordance with the condition of the balance between gravity and buoyancy of ship in waves and also with that the sum of trim moments is zero are obtained.
对动态电荷群的研究得知能够实现这种悬浮力。 较简单的情形是只要两个动态点电荷满足三个条件,它们各自受到的力就会指向同一方向,力的大小按正弦规律变化,合力不为零且稳定不变。
A simple type is that the forces on two dynamic point charges have the same direction, the scale of the forces are changeable with sine regularity and its' resultant force is stable and nonzero.
