Thrust block may bridge the space between the termination of the arch and the foundation rock at the same elevation . 推力墩可以跨在拱脚和同高程的基岩之间。
One approach consists of varying only the total flow thereby maintaining the same thrust chamber hardware . 有一种方法是仅改变推进剂总流量，而推力室结构保持不变。
These thrust losses may be very large if the inlet flow distortion is in the order of 15 to 20 percent . 若进口流场的畸度在15-20范围内的话，则推力损失就可能十分巨大。
This means that the gas exerts a jittery force which our coarse senses feel only as an average push . 这意味着，气体施加一个颤动的力，而我们粗糙的感官只感到一个平均的推力。
Mighty nova, if it ever is brought to completion, may have a take-off thrust of 6, 000, 000 pounds . 强大的“新星号”月球火箭如果得以制成，其起飞推力可达6，000，000磅之多。
He also wrote other papers on the subject and dealt with the resistance encountered by ships and ship propulsion . 他在这个题目上连写了一些别的文章，处理船受到的阻力和船的推力。
Jet engines with which most modern high-speed aircrafts are equipped develop thrust on the same principle as the propellers of conventional aero-engines . 大多数现代高速飞机装备的喷气发动机产生推力的原理，与普通航空发动机的螺旋桨相同。
The mechanical properties of improved double-base propellants enabled one to envisage grain geometrics with large combustion areas and consequently high thrusts . 经过改进的双基推进剂的机械性能使我们能够指望获得大燃烧面的药柱几何形状，从而得到大推力。
