三角

Using analytic geometry or trigonometry, we can easily prove that the area of the "hidden" lozenge is equal to that of a small square of the chessboard.

运用分析几何或者三角法，我们很容易可以证明"藏起来"的菱形就是那个棋盘上的小方格。

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。
