逆风

The convection term in turbulence equations is discretized using first-order upwinding scheme to ensure more stability in time integration and the positivity of the turbulent variables.

对湍流方程中的对流项，则采用一阶逆风格式离散，以进一步保证时间推进的稳定性和湍流变量的正值性。

The results show that when gravity wave's propagating in the homogenous winds, the nonlinearity is stronger in the fair wind than in the contrary wind, the background winds change the propagation velocity and path, and when gravity wave's propagating in the homogenous winds, the vertical wavelength decreases, the average upgoing energy flux reduces which implies the ambient winds absorb the energy of the wave, realizes coupling of the different atmosphere layers.

结果表明，当重力波在均匀风场中传播时，非线性效应在顺风场中比在逆风场中更显著，背景风会改变重力波在水平方向的传播速度和传播路径；当重力波在剪切风场中传播时，重力波在垂直方向上平均能流随高度的增高而减少，表明背景吸收了重力波的能量，在重力波向上传播的过程中，实现了大气各层之间的耦合。

Out of town they used towlines ina headwind and hoisted 8 scrap of sail if the wind was behindthenl.but did not have resources of propulsion possessed by othercr'aft.

到了城外去，遇到逆风固然也会拉纤，遇到顺风固然也会张一扇小巧的布篷，可是比起别种船上的驾驶人来，那就不成话了。

The system adopts C8051F020 single chip microcomputer to realize the communication with the robot principal controller by means of serial port. With a compact structure, the performance of the system is unaffected by the installation position, so it can be assembled to other type of robots as a robot standardized component , in order to help the robot to complete the olfaction-related work.3. Inspired by the foraging strategies of animals, a strategy of odor source localization is put forward based on the animal predatory behavior. The strategy fuses the information of gas sensor, wind direction sensor and ultrasonic sensor etc. and integrates several good search algorithms such as Z-shaped search, upwind search and fuzzy neural network search and so on.

该系统结构紧凑，性能不受安装位置影响，可作为机器人标准化组件组装到各种类型的机器人上，以帮助其完成与嗅觉有关的工作。3、受动物捕食策略的启发，提出了一种基于动物捕食行为的机器人味源定位策略，融合了气体传感器、风向传感器、超声传感器等传感器信息，整合了&Z&形搜索、逆风搜索，模糊神经网络搜索等多种较优的搜索算法。

There is a saying goes to the effect that if this vessel has no compass, then all it has or all it runs into will be headwinds rather than tailwinds.

有一句谚语：这样的船只有逆风，也不会有顺风。

It is comforting to be in a business where some mistakes can be made and yet a quite satisfactory overall performance can be achieved. In a sense, this is the opposite case from our textile business where even very good management probably can average only modest results. One of the lessons your management has learned - and,unfortunately, sometimes re-learned -is the importance of being in businesses where tailwinds prevail rather

保险这行业虽然小错不断，但大致上还是可以获得不错的成果，就某些方面而言，这情况与纺织业刚好完全相反，管理阶层相当优秀，但却只能获得微薄的利润，各位的管理阶层所学到的一课，很不幸一再学到的就是，选择顺风而非逆风产业环境的重要性。

Walking against the wind, in the water,while wearing a backpack burns about 50 more calories per hour than walking with no resistance. People who wear pedometers also tend to burn more calories and lose more weight.

逆风行走，逆流而上或背上背囊相比那些步行无风阻的人，每小时会燃烧约多50卡路里的能量，而那些身背计步器的人往往燃烧更多的卡路里，减肥效果更明显。

If I feel all-powerful I will try to stop the wind.

当我觉得自己充满力量时，我会试着去逆风而行。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
