	3.	When the sun shines and there are no clouds , the sky is clear . 当太阳照耀而且无云时，天空是晴朗的。
	4.	I felt depleted and wrecked as i stared blankly out the window at pink - gray clouds slowly traversing the afternoon sky 当我茫然地盯着午后窗外的天空掠过粉灰色的云时，感到心力交瘁。
	5.	Waliguan over the whole time period . the surface uv - b irradiance increases significantly while the total ozone decreases year after year 当天空有云时， uv - b通常减小，但偶尔也出现增大的现象。
	6.	Scientists have created ice at room temperature , potentially explaining a mysterious variation in the temperature at which clouds form . scientists have created ice at room temperature , potentially explaining a mysterious variation in the temperature at which clouds form . by exposing water to a weak electric field , they have produced what is being called " hot ice " 美国物理评论快报杂志及最新一期的新科学杂志日前刊登消息称，韩国科学家已成功将室温约20摄氏度下的水变成了冰，而这一试验的成功可以解释诸如水形成云时温度变化不一等自然现象。
	7.	Main conclusions drawn from the analyses of calculating results are as follows : ( 1 ) the microwave absorption of atmosphere gas have obvious attenuation at the wavelengths for cloud detection , thereinto , the water attenuation effect changes greatly , so the 94ghz cloud detecting radar should have water vapor attenuation correction scheme . ( 2 ) when 37ghz and 94ghz radars detect clouds , the difference between the atmosphere and cloud attenuation and the large variety of radar reflectivity conduce the intension of the radar backscatter signals change . ( 3 ) for the thin cloud layer and low water content of cloud , 37 - ghz radar backscatter signals are not as good as 94 - ghz radar , that is to say that the 94ghz radar has better capability in thin clouds detection 本工作得出如下结论： ( 1 )大气气体的微波吸收在测云波段产生明显的衰减，其中水汽衰减效应变化很大；即将上天的空间94ghz测云雷达必须有水汽衰减订正方案； ( 2 ) 37ghz和94ghz雷达测云，由于大气和云衰减不同和雷达反射率的很大差异，导致雷达回波信号强弱不同； ( 3 )对云层较薄、含水量较少的云，在不计雷达参数的情况下， 37ghz雷达回波信号不如94ghz测云雷达，也就是说94ghz对薄云有更强的探测能力；对云层较厚、含水量大的云，由于强衰减的作用， 94ghz雷达回波信号小于37ghz雷达； ( 4 )从大气衰减的不利因素方面考虑，空间94ghz雷达测高层薄云的效果最好；测低层薄云时需要考虑气体衰减订正；因浓厚云的强衰减作用，探测其中下部的能力大大减弱，不仅要进行衰减订正，而且要借助其他信息来反演整个云层的含水量垂直分布； （ 5 ）为了获得从极薄到极浓厚云的垂直分布探测能力，未来测云雷达系统最好采用双波长甚至三波长（如94 、 37和13ghz ） 。
