The results show that the wind loads on the roof structure are mainly suctions. and the wind loads on the windward and leeward of the roof structure near the ground are positive. The differences among the results of four turbulence models were not notable.

结果表明，此类大跨度椭球屋面风压分布主要以吸力为主，靠近地面的屋面迎风面和背风面风压为正压。4种湍流模型的模拟结果之间差异较小，数值方法能够较准确地模拟该类大跨度椭球屋面的风压分布。

Through field investigation on soils of different tillage ways and soils with different kinds of stubbles,the results indicated that,the effect of anthropogenic factors on wind erosion is great,and wind erosion of grasslands, soils with stubbles and ploughed farmlands was obvious different.

留茬地因为表面残茬的存在显著增加了土壤表面粗糙度，从而使得其风蚀强度较小；而秋翻地人为扰动较大，表面覆盖度较小，其风蚀强度在所研究的土壤中为最大。

The order of surface roughness under no-tillage with different standing crop stubbles is millet forage＞maize forage＞oats＞rape, while the order of the soil wind erosion modules is rape＞oats＞maize forage＞millet forage. The larger the soil wind erosion modules are, the smaller the surface roughness is.

留有不同直立作物残茬免耕土壤地表粗糙度草谷子＞草玉米＞莜麦＞油菜，土壤风蚀侵蚀率呈现相反的趋势，地表粗糙度越大，风蚀侵蚀率越小。

The results show that saltating snow particles have important effects on wind velocities near surface and Magnus lifting force also has effects on the wind profiles as well as saltating trajectories of snow particles.

计算结果表明，跃移雪粒对贴地风速有重要影响，Magnus效应对贴地风速、雪粒跃移轨迹也有显著影响

Firstly, saltating sand grains in various height layers mostly rotate clockwise; the rate of counterclockwise rotation changes from 16.7 to 33.3% for three different friction wind speed (u*= 0.67, 0.83, and 0.87 m/s). However, their mean rotational speeds were not significantly different, irrespective of whether the grains rotated clockwise or counterclockwise. The mean counterclockwise rotational speeds of sand grains for friction wind speed u*= 0.67, 0.83, and 0.87 m/s were 427, 519, and 604 rev/s, versus 429, 522, and 609 rev/s, respectively, in the clockwise direction.

首先，风沙流中各高度层内跃移沙粒旋转均以顺时针方向为主，逆时针方向旋转的沙粒数仅占总数的16.7-29.5%，但是无论逆时针还是顺时针旋转的沙粒，它们的平均旋转速度几乎没有差别(如u*＝0.67 m/s时，分别为427 rev/s和429 rev/s；u*＝0.83 m/s，分别为519 rev/s和522 rev/s；u*＝0.87 m/s，分别为604 rev/s和609 rev/s)；不同摩阻风速条件下各高度层内沙粒的旋转速度均服从Lorentzian分布。

The number of lift-off sand grains percent time percent sand bed area Based on the lift-off velocity distribution function of saltating sand grain, this thesis gains the number of lift-off sand grains percent time percent sand bed area which ranges from 6796 to 8846900 number/(s·m2) by combination motion model of single saltating sand grain and some motion parameters of saltating sand grains and the flux of wind sand current from wind tunnel experiment.

单位时间单位面积沙床起跳沙粒数利用本文获得的沙粒起跳初速度分布函数，结合沙粒跃移运动学模型以及风洞实验中获得的沙粒跃移运动参数以及输沙量，反演出一定风场条件下单位时间单位面积沙床起跳沙粒数，变化范围6796-8846900个/(s·m2)，并满足。

At this moment blast has been blown (that as it happens is an off-street), seemed suddenly to be endured on my face one fist like ache, look later, a bunch of mop that is the decoration of doorway of a drug-store on the side and broom are put in a white plastic painful in be blown by wind, as it happens is hit in my right face, I am calling merchant, one woman runnings to ask how to return a responsibility, the thing that I say you is blown by wind hit on my face very ache, she is spoken unexpectedly perhaps is the thing that you struck me!

这时一阵风吹过，忽然我脸上好象被挨了一拳了似的疼，回头一看，是旁边的一个杂货店门口摆设的一捆拖把及扫帚放在一个白色塑料痛里被风刮倒，正好打在我的右脸，我呼唤着店主，一妇女跑出来问怎么回事，我说你的东西被风吹到打在我脸上很疼，她居然说出&说不定是你撞到了我的东西吧！&

This article analyzed the wood strength, crown shape, root distribution, tree age, wind speed, soil quality, ground pavement, groundwater level, light and other natural factors, and studied the planning and design, construction management and other human factors; explored the various reasons for the wind damage in road greening, and put forward suitable methods for the anti-typhoon technology for newly-built and existing roads.
