air drops

The American and British air drops are vital .

美国和英国的空投至关重要。

There have been air drops by the Americans , the Turks in the Iraqis of food .

美国、土耳其和伊拉克实施了空投食物的援助行动。

Unless , heaven forfend , an attempt were made to take over the administration of Myanmar , which would involve an armed invasion , the action would be confined to air drops .

除非以武力强行进入缅甸，推翻现政权，展开援救，但这是天理所不容的，否则救援工作也只能限于空投。

Once you open the door , and all the cold air drops out , when you close it again , the fan directs more cold air into the cabinet lot quicker than it does on the other types of designs .

一旦你打开冰箱门，所有的冷空气都会被放出，当你再次关闭的时候，风扇把更多的冷空气引入冷气室，其制冷速度要比其它类型的设计更迅速。

There were basically no green areas in cities , so the air quality drops because there is no natural regeneration of the air .

在城市中几乎没有绿色植物，因此没有自然的空气代谢的时候，城市的空气质量就下降了。

As the cost of both the radio devices and the air time drops , more and more measurement and reporting will be done with wireless networks .

随着无线电装置及发射时间两者成本的下降，越来越多的测量设备和报告将通过无线网络来完成。

Experimental studies have been performed on the board of Russian IL 76 reduced gravity airplane for two phase air water pressure drops in a square cross section channel .

利用俄罗斯IL76失重飞机对微重力条件下方形截面管道内的水/气两相流压降进行了实验研究。

The radial distributions of the mean and fluctuating velocities of the air flow and drops , the drop size and the concentration were measured at several axial stations with2D PDA .

实验用二维激光测速测粒仪对喷嘴下游几个截面上气流和液滴的平均速度和脉动速度，以及液滴的粒度和浓度沿径向的分布进行了测量。

The local density of states takes much larger values in the air cylinders areas and drops down at the boundary between the air cylinders and dielectric medium background , and this phenomenon is due to the continuity of electric displacement vector .

第二，局域态密度在空气散射子界面处发生突变，空气散射子区域的局域态密度相对较大，这可由电位移矢量的连续性来理解。

Recently , research interest on increase of the air side heat transfer coefficients and reduction of the air side pressure drops of parallel flow condensers and alike compact heat interchangers has became one of the hot spots in heat transfer enhancement domain .

如何有效提高平行流冷凝器类紧凑式热交换器的空气侧换热系数，降低空气侧压降就成为近年来强化换热领域的研究热点之一。

The rising air meets the cold dry air that has already existed in the storm clouds , thus the temperature of the warm air drops , and the water vapor in it condenses into tiny droplets that are a precondition of rain .

正在上升的暖湿气流遇到雷暴云层中原本就存在的干燥冷空气，此时热空气的温度下降，里面的水分凝结成小的水滴这是形成雨水的前提。
