稀薄的

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。

Right off the bat, the lander's robotic scoop appeared to hit solid ice just below the surface, and scientists were rewarded with time-lapse images of ice subliming into the thin Martian atmosphere from one of the trenches it dug.

凤凰号在当初刚着陆时，它的机械铲铲似乎就碰到了地表下的固态冰，同时科学家们也满意得看到了，在它挖出的一个沟渠中有冰升华到火星稀薄大气层中的延时图像。

True, I talk of dreams, which are the children of an idle brain, begot of nothing but vain fantasy, which is as thin of substance as the air and more inconstant than the wind, who wooes even now the frozen bosom of the north, and, being anger'd, puffs away from thence, turning his face to the dew-dropping south.

对了，梦本来是痴人脑中的胡思乱想；它的本质像空气一样稀薄；它的变化莫测，就像一阵风，刚才还在向着冰雪的北方求爱，忽然发起恼来，一转身又到雨露的南方来了。

True,I talk of dreams,Which are the children of an idlebrain,Begot of nothing but vain fantasy,Which is as thin of substance as the air And more inconstant than the wind,who wooes Even now the frozen bosomof the north,And,being anger'd,puffs away from thence,Turning his face to the dew-dropping south.

茂丘西奥对了，梦本来是痴人脑中的胡思乱想；它的本质像空气一样稀薄；它的变化莫测，就像一阵风，刚才还在向着冰雪的北方求爱，忽然发起恼来，一转身又到雨露的南方来了。

These modifications simplified molecules' moving and collision computation, and also avoid the consumption of unnecessary RAM. The modified ALTS method was adopted in the DSMC code.

应用改进后的自适应时间步长法，对圆柱的稀薄气体绕流进行了采用和未采用改进的自适应当地时间步长法的对比计算。

Garrigue Scrub woodland a secondary formation derived from the original mixed forest, characteristic of limestone areas of the Mediterranean region, with low rainfall and thin, dry soils.

咖里哥宇群落：是多矮小植物，起源于原始混合森林的次级群落，该群落具有的低降雨量及稀薄干燥的土壤，是地中海石灰岩地区的特征。

A very important necklace has just been completed by the house of Graff, for example, that is an intricate filigree of the finest coloured diamonds pinks, blues, cognacs and yellows of the subtlest hues.
