And the wind area的意思|示意

Coarse sand in the Yellow River mainly comes from sand rock area, Inner Mongolia, water erosion, wind erosion and gravitational erosion occur interactively in this area.

内蒙古砒砂岩地区是黄河重要的粗沙来源区，该地区具有水蚀、风蚀及重力侵蚀交互的特点。

The area is frequently beset with sudden storms, snow, wind and the weather may change quickly in a day.

该地区经常会面对突如其来的暴风雨，大雪，大风以及一天之内天气会不断的变化。

The variation of wind profile structure in Naqu area with the process of rainy season is analyzed by using the wind profiler data and statistic method.

本文利用此次探测资料，通过统计分析和典型个例分析相结合的方法，研究了雨季到来前后那曲地区大气边界层的风廓线结构特征。

The power expression by the wind passing through the rotor swept area of back wind direction wind turbine is accurately deduced from energy viewpoint based on wind shear and tower shadow effect.

从风力机获取能量角度出发，充分考虑风剪切与塔影效应，精确推导出作用于下风向风力机风轮扫掠面积上理论风功率的计算式。

Vibrating in the wind, the bristles create some drag. But they also reduce the wing's slipstream, an area of low-pressure turbulence that pulls back on the wing, and hence reduce drag.

风中振动时，刷毛会产生反作用力，但同时它也可以减少机翼滑流，产生一个低气压乱流，机翼上形成回力，因而减小阻力。

For example, with the wind at an intensity that a sloop might have to double-reef the main to reduce sail area, a ketch may sail very well under just jib and mizzen.

例如，当风速在某个强度上时，单桅帆可能必须将主帆四叠起来以减少帆面积，而双桅帆则可以只用前帆和后帆来顺利航行。
