气流

In spring, the wind field around Korea was mainly a northwesterly flow, while in summer it was west-southwestern flow. This fact leaded sand aerosols of the northern part of China and Mongolia and industrial aerosols of the eastern part of China to be transmitted to Korea well.

春季在韩国周围的风场主要有西北气流，在夏季有西-西南气流，兼有利于中国北部和蒙古国频繁发生的沙尘以及中国东部工业地区出现的高值气溶胶粒子传输到韩国。

The upper-level wind above Korea was usually the westerly wind, while the low-level wind was the northwesterly wind.

在沙尘天气过程中，在韩国附近高低层都形成了西北气流，其气流有利于输送沙尘。

The results show that the heavy fog occurred under the atmospheric circulation pattern controlled by the straightwesterly air flow at 500 hPa middle latitudes, northwesterly air flow orweak high p ressure circulation atmiddle and low levels, and weak p ressure in front of the surface high.

发现这次大雾天气发生在500 hPa中纬度平直偏西气流、中低层西北气流或弱高压环流以及地面高压前部弱气压场控制的大气环流形势下。

NOSE CONE, A device on the front of the engine that guides airflow to the primary airflow path of the engine.

Combined with the measured data of the supply air flow distribution in the existing air-conditioning vents on the audience's part of the theater, the temperature and velocity distribution are calculated under the design project condition, obtaining that air current organization of the pond place and the gallery under this blast form indeed has many problems, proposing the orbed nozzle in the balcony can be replaced by swirl diffusers vertical vents, and the blast form of the gallery will be changed by under-seat air supply.

结合现场所测的数据对观众厅部分现有空调喷口送风的气流组织做简要的计算和分析，并简要计算了设计工况下速度分布和温度分布，明确该送风形式下的池座和楼座的气流组织的确存在诸多问题，进而针对池座提出用旋流风口代替球形喷口垂直下送，楼座则建议改为坐椅下送风。

Pneumatic"and"ordered (that is to say, air field and ordered movement of the pot seedling) are the two key technologies of the ordered pneumatic throwing transplantation, the two technologies were analysed by ANSYS software on the basis of CFD theory and explicit nonlinear dynamic theories for the first time in China. Some correlative experiments were also carried. The basic characteristics about the air field and the ordered movement of the pot seedling were gained.

在计算流体力学和显式非线性动力分析理论的基础上，本文在国内首次采用ANSYS有限元软件分析了气力有序抛栽的2项关键技术——"气力"和"有序"（即抛栽气流场和钵体苗的有序运动），并进行了相关的试验研究，获得了抛栽气流场和钵体苗运动的基本特性，为气力有序抛栽技术的优化提供了依据。

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。

Based on the pentad mean Outgoing Longwave Radiation and 850hPa wind data during 1979 to 1986, the circulation in the tropical eastern Indian Ocean and western Pacific Ocean are analyzed.

作者利用候平均OutgoingLongwaveRadiation资料与850hPa风场资料(1979～1986年)对热带东印度洋—西太平洋海域与越赤道气流有关的环流系统做相关分析和越赤道气流偏强类合成分析。

These results indicated that this simulation method could factually express air environment in the piggery, and it was an effective method for air temperature and airflow speed simulation in piggery.

表明使用CFD模拟方法能够真实表达猪舍内气流状态，对猪舍内温度场和气流场的模拟是一种有效的方法。
