A nonlinear eddy-viscosity turbulent flow model, which adopted third-order correlation of stress tensor and strain tensor, was modified and applied to flow computing of turbulent flow of internal combustion engine.

把采用了应力张量和应变张量的三阶相关关系的一个非线性涡粘度湍流模型进行修正后应用于内燃机缸内湍流流动计算，用此模型对几种ω形凹坑燃烧室内燃机汽缸内的流动进行计算，特别考查不同结构燃烧室内各处的湍能的变化，给出了燃烧室结构对缸内湍能影响结果，结果表明，凹坑结构时内燃机缸内湍能的分布和平均湍能的大小影响很大，可适当调整燃烧室结构来改变缸内湍流结构。

It basically operates the main point as follows: The left hand holds the ticket, the palm is downward, the thumb is pinned in the middle of the left end of the front of the bank note, the forefinger and middle finger are on the back of the bank note, pinch the bank note together with thumb; Left hand the third finger naturally curly, pinch, get up bank note little finger stretch to bank note front push down bank note below the Left deviation; The middle finger of left hand is exerted oneself slightly, the bank note of tight card together with the third finger, little finger; The left hand forefinger is stretched, the thumb is moved upwards, pin the side of the bank note, keep the bank note into the tile shape; Left hand wipe from tabletop bank note, bank note turn, thumb strength wiped from tabletop to borrow prop up bank note covering of a fan and oblique to oneself of WeiKai Cheng; Three fingers of right hand dip in water, rotate and move the lower right corner of the bank note downwards sharp with the thumb, the forefinger cooperates with the thumb to rotate and move on the back of the bank note; Play in one's arms, count while ordering with right hand the third finger bank note got up to rotate; Pay attention to the posture at the some paper money, the health is straight and upright, the eyes It must keep eyeball and bank note from,put dual tactics elbow at tabletop.

其基本操作要领如下：左手持票，手心向下，拇指按住钞票正面的左端中央，食指和中指在钞票背面，与拇指一起捏住钞票；左手无名指自然卷曲，捏起钞票后小拇指伸向钞票正面压住钞票左下方；左手中指稍用力，与无名指、小拇指一起紧卡钞票；左手食指伸直，拇指向上移动，按住钞票的侧面，将钞票压成瓦形；左手将钞票从桌面上擦过，钞票翻转，拇指借从桌面上擦过的力量将钞票撑成微开的扇面并斜对自己面前；右手三个指头沾水，用拇指尖向下捻动钞票右下角，食指在钞票背面配合拇指捻动；用右手无名指将捻起的钞票往怀里弹，边点边记数；点钞时注意姿式，身体挺直，眼睛和钞票保持一定距离，两手肘部放在桌面上。

It can get the three-dimensional profile of the object surface effectively. Because of the cragginess of the three-dimensional surface when sine grating is projected the image of the sine grating is modulated and the modulated image is taken by a CCD camera with an angel compared to projecting direction. After the phase shift measuring method, the phase is gotten. Because the phase is calculated by the phase shift measuring ranges from –π to +π it isn't continuous. The phase unwrapping is necessary to recover the continuous phase about the object shape.

这种方法采用结构光照明，将正弦光栅图像投影到被测物体表面，用与投影方向成一定角度的CCD摄像机获取受物体表面面形调制的变形光栅像，根据数字相移算法计算出相位分布，由于从相移计算的相位被截断在反三角函数的主值范围内，因而是不连续的，必须通过相位展开恢复出连续相位分布，由相位－高度关系最终求出物体轮廓的三维数据信息。

In this paper, the 3D FEM models of cone-tread and worn-tread locomotive and vehicle wheels are firstly established, which come into contact with the rail of standard size. There hasn't been any more refined 3D FEM computation model of wheel/rail up till now. The elastic effect of crosstie and roadbed is also considered.
