In this paper, the direct simulation Monte Carlo method is employed to simulate flows of modeled air vehicles having simple geometric shape such as delta wing at a Knudsen number between 0.001 and 0.1 for various Mach number and angle of attack conditions. With the calculated aerodynamic forces and heating, we obtained the general behavior of the rarefied gas effects on the vehicles' aerodynamics.

本文采用直接模拟 Monte Carlo 方法，模拟了简单外型如三角翼形的模型飞行器在努森数为 0.001到 0.1的范围内以不同来流马赫数和不同飞行攻角飞行时的流场，计算了飞行器所受到的气动力和气动热，获得了稀薄气体效应对飞行器气动性能影响的一般规律。

In virtue of Fluent of CFD software, we carry though computation of aerodynamics of an air-to-air missile in different Mach meter and different attack angle and gained movement trend of lift coefficient、drag coefficient and pitching moment coefficient with variety of Mach number and attack angle, meanwhile, we also obtain distributing trend of pressure, temperature and weather velocity.

借助于商业CFD软件FLUENT，对某型空空导弹在不同攻角、不同飞行马赫数的气动力进行了计算，得出了该型导弹升力系数、阻力系数和俯仰力矩系数随飞行马赫数和攻角的变化规律以及导弹表面的压力分布、温度分布和来流速度分布。

The commercial CFD software Fluent was used for simalation of aerodynamic charactirestics of some terminal guided munitions in terminal segment under different affack anyle and mach, the variation lav of or lift coeflienct, drag coeflient and roll moment coefficient with flight mach and attacls angle was obtained, The semulation result shows the caculated aerodynarve parameters can be referend to high accuracy firing table for the terminal guided projectile.

文中主要利用商业CFD软件Fluent对某型末制导炮弹的末制导段在不同攻角、不同飞行马赫数的气动特性进行了数值仿真，得出了该型末制导炮弹升力系数、阻力系数和滚转力矩系数随飞行马赫数和攻角的变化规律。结果表明，计算所得气动参数可以为该末制导炮弹编制高精度射表提供数据依据和参考。

The operating principle and performance of time-of-flight mass spectrometer were introduced.

介绍了飞行时间质谱仪的工作原理及性能特点、莱钢4号转炉应用的飞行时间质谱炉气在线分析系统的组成、安装布局及其同其他生产设备间的相互衔接，以及在现场达到的性能指标。

Then, the Simulink toolbox in the Matlab is used to establish the model to implement the complex kinetic equations based on the principles of hierarchy and C MEX S-function.

研究了大气风场，分析其对飞行轨迹的影响。然后，在Simulink环境下进行建模，采用C MEX S-function编程实现了复杂的飞行力学运动方程组。

Charles A.lindbergh who drived his monoplane named Spirit of St louis flying across Atlantic from New york City to Paris of France on May 20-21,1927,had been glorified as one of the most greatest American heroes and worshipped by many generations of American people for more than eighty years.

林白的飞行事业之所以产生了如此深远的影响，除了飞越大西洋以及此后数次长距离、长时间飞行本身所具有的新闻性和轰动效果之外，从外在原因来看，1920年代整个美国社会的客观环境以及美国大众的精神状态也是造就林白这样一位时代英雄的主要契机。

The first clearly recorded instance of balloon passengers were not humans, but a sheep, a duck and a chicken on an 8-minute flight over France on September 19 1783, in the Montgolfier brothers' first demonstration flight for King Louis XVI, proving that humans would be able to breathe at these higher elevations.

在清楚记录的气球乘客一审不是人类，而是一只羊，一只鸭子和一个8年09月19一千七百八十三分钟法国上空飞行了一只小鸡，在孟格菲兄弟'的国王路易十六首次飞行表演，这证明了人类能够呼吸在这些高海拔地区。
