背风的

Slender body is a widely used forebody configuration for modern advanced fighters and tactic missiles.

现代先进战斗机和战木导弹常具有细长前体，大攻角条件下前体背风面会形成非对称涡结构，从而产生很大的侧向力和偏航力矩，这会严重影。。。

In rotating atmosphere geostrophic adjustment prevents real upstream effects from forming but favourites high wind speed development in lee side.

旋转大气中地转调整过程抑制真正的上流效应生成，而有利于背风坡上强下泄风形成。

Toward a lee shore in a gale, is steered for a particular spot by her skipper because he knows of an undertow there which will hold her back against the gale and save her. For just pure woodcraft, or sailorcraft, or whatever it is, isn't that neat For several years, Cooper was daily in the society of

然而他却会郑重其事地向我们描述在狂风大作之际一位船长如何把船驶向背风岸的某个特定地点，因为船长知道有一道逆流，而这道逆流不会让船给风吹跑，会挽救这艘船。

However, in terms of the whole branch, the most difference of aboveground biomass allocation and tissue water content ratio is presented to S. gordejevii growing at the bottom of lee wave.

然而，就整个枝条而言，干生物量分配和组织水分比例均以生长在背风坡底部的黄柳差异最大。

Most tourist areas in Hawaii are on the leeward and south sides of the islands.

大多数旅游区是在夏威夷背风和南北双方的群岛。

The location and scope of "corner flow" and leeward trough were different.

"角流"和背风槽的位置和范围不同。

Then, the fronts .of different intensities are superposed on the orographic disturbances and pushed by basic geostrophic flow to climb over the orography.

通过非静力模式讨论了两维地形扰动与锋面的相互作用，研究了不同基本气流，包括正压、斜压、层结强弱差异，不同尺度的地形，包括不同高度和不同宽度，强弱不同的锋面等多种情况下地形扰动与锋面扰动的相互影响，发现地形尺度和气流的性质不同带来的结果是有差异的，中尺度地形使冷锋在迎风坡锋消，在背风坡则是锋生和锋消相间的波状分布，表现为锋面在山顶附近锋生、快速下坡过程中锋消和山脚处锋生的分布特征，这与半地转模式中地形的动力作用使冷锋在背风侧单纯加强是不同的。

The results show that a separate dunk is observed near the stagnation point of the second sphere on the distance of spheres L≤2.5D because of the influence of reverse pressure gradient.

结果表明：当L≤2.5D时，由于逆压梯度的影响，在第二个圆球滞止点附近捕捉到附体分离泡；由于第二个与第三个圆球的置入，展向压力梯度诱发第一个圆球背风面流动的展向输运，且随着圆球间距的增加流场的展向输运趋势减小，但涡的强度增大；第二个圆球与第三个圆球背风面流动没有明显的展向输运；湍动能的增量与圆球间距近似成平方规律。

The width effects of dune are studied and the reason that the barchan dune is formed on the lee slope of dune is given.

但对于背风坡形状的形成，特别是对新月形沙丘，这样一种沙漠、戈壁上最常见的相对稳定的横向沙丘的背风坡新月形落沙坡的形成和保持，无有完整的理论分析，只是简单地认为其坡度不能大于沙子的摩擦角而已。

The density of the foot 、middle part and top are 124grain /m~2、91 grain /m~2、66 grain /m~2,the seeds is more little windward than the leeward.The density of seed banks in windward is 81grain/m~2 and the leeward density is 100grain/m~2.The seed of ephemerals bourgeoning reaches the pinnacle on April and May.The diversity of different parts sand dune is different,but the differences do not reach the marked level.The similarity is high between the seed banks and the vegetation.

迎风坡种子库密度比背风坡面少，迎风坡种子库平均密度为81粒/m2，而背风坡种子库平均密度为100粒/m2；短命植物种子在4月上旬达到萌发高峰，沙丘不同部位物种多样性存在差异，土壤种子库和地上植被存在较高的相似性，此外短命植物在沙丘不同部位的分布存在较高的空间异质性。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
