By the Song dynasty, people will be in the bamboo tube filled with gunpowder, the gunpowder behind the bar there is a small "directional stick", lit on fire tube Huoxiao

到了宋朝，人们将火药装填在竹筒里，火药背后扎有细小的"定向棒"，点燃火管上的火硝，引起筒里的火药迅速燃烧，产生向前的推力，使之飞向敌阵爆炸，这是世界上第一种火药火箭。

Generally,the best efficiency is obtained in second order vibration mode of the fishtail,and the reverse Karman Vortex Street wake is observed with corresponding frequency.

在一般情况下当外磁场以系统的二阶固有频率工作时其工作效率最佳。在此情况下鱼尾摆动产生了推力型反卡门涡街形态的尾迹涡流。

The preceding chapters have listed five basic motion patterns and their symbols: free fall; five-fingers, scales, and arpeggios; rotation; staccato; and thrust.

在以前的章节中已经列出五个基本动作模式和它们的代表符号：自由下落；五手指音阶、琶音；转动；断奏；推力。

The flight management computer system continuously calculates the optimum flight path and engine thrust to save time and fuel.

飞行管理计算机系统继续计算最佳的飞行路径及发动机推力，以节省时间和燃油。

A novel tubular permanent magnet linear servo motor was proposed. The motor applies the axial magnet array topology of the secondary rod, and the air-cored armature windings and slotless structure of the forcer, which totally eliminates the cogging force of general permanent motors.

介绍了一种圆筒型永磁直线伺服电机，电机次级采用轴向磁通结构，初级采用无铁心空心式绕组设计，完全消除了传统有铁心永磁电机固有齿槽效应所引起的推力波动问题。

基于二阶系统模型，利用傅里叶展开的方法，分析了在多脉冲推力作用下测量系统的动态响应。

We do not want to mix the thrust with either the free fall or with any throw motion.

我们不想将"推力"与自由降落或其它的投掷动作相混。

We are in a real jam.

我们的麻烦大了。
