具有成本低、寿命长、风险小等优点，在一定程度可取代成本高昂的卫星和空间飞行器。用于通信领域和空间科学研究领域，具有十分广阔的应用前景。

Main scraping mud surrounding a drive-and-transmission center, the stratospheric rectangular truss car-pool, the chain of transmission, such as.

刮泥机主要有周边传动式、中心传动式、矩形平流池桁车式、链传动式等。

International environmental organizations have determined to eliminate production and usage of chlorofluorocarbon , but CFCs have long atmospheric residual lifetimes, even if all countries wold strictly execute the protocol, stratospheric ozone recovery would still needs a long period.

尽管国际环境组织已明确规定停止氯氟烃的生产和使用，但由于CFCs具有很长的大气寿命，即使所有国家都严格执行国际环境组织的规定，平流层臭氧恢复仍需要一漫长过程。

The main chemicals that are depleting stratospheric ozone are chlorofluorocarbons, which are used in refrigerators, aerosols and as cleaners in many industries and halons, which are used in fire extinguishers.

破坏同温层臭氧的主要化学物质是使用於冰箱的氟里昂，气溶胶，在许多工业中使用的清洁剂和使用於灭火器中的一种灭火剂。

"Crapshoot" is not quite accurate, but Keefer saw an element of randomness in Parker's stratospheric rise: What if it was another time in history that was for the so-to-speak 'gambler,' then it would be Tom Shanks who would be trading a billion dollars and Jerry Parker would be trading $250 million.

"有风险的事业"这个说法还不精准，科夫认为成功也有随机的因素：一般人都认为这是赌博，如果时间变换一下，也许是汤姆·桑克斯在交易几十亿美元，而杰瑞·帕克才交易2500万美元。

Beginning with characters of stratospheric environment, analyzed four key technologies in achieving the goal of fixed-point resident of airships, which are attitude control, drive control, flotage control and position control.

从平流层的环境特点出发，分析实现飞艇的定点驻留所需要解决的姿态控制、动力控制、浮力控制和位置控制等4类关键技术。

The stratospheric sudden warmings in 2002/2003 and 2003/2004 winters are analyzed using the daily four times ECMWF data. The differences of the average temperature and zonal wind are compared between these two winters, with calculating EP flux and the residual mean circulation.

利用ECMWF提供的60层气象场资料诊断分析了2002/2003和2003/2004年两个冬季的爆发性增温(stratospheric sudden warming， SSW)过程，比较了两次SSW期间高纬温度和纬向风的差异，计算了SSW期间的EP通量和剩余环流。

The results indicate that winter SSWs are catastrophes due to the variations of model parameters and are stratospheric responses on the bottom boundary forcings, and that the SSW is very sensitive to the initial state of stratospheric zonal wind.

结果表明，冬季平流层增温是由于模型参数变化而导致系统灾变的结果，是冬季平流层对底部强迫的响应，它同时对平流层基本流的剖面十分敏感。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
