在晴天和阴天大气向土壤的能量传输均维持在净辐射的5%左右，雨天时，土壤热通量为负值。
Soil heat flux from atmosphere to soil is about 5% of net radiation on a clear and cloudy day and soil discharge energy to atmosphere on a rainy day above the same field.
使其能在晴天和阴天根据人体的最适光照强度来调节输出功率，进而调节灯管亮度。
So that it can be sunny and cloudy days in accordance with the human body to regulate the optimal light intensity output power, thereby adjusting lamp brightness.
结果表明：晴天大气向土壤传递热量，阴天和雨天土壤释放的热量大于获得的热量。另外还分析了土壤热通量季节和年变化特征。
The results show that the soil accepted heat from the air on clear day, on the contrary, the output heat of soil exceeded the input on cloudy and rainy day.
中国大部分地区都会是晴天． 我们将看到大部分的晴天和局部阴天而不是阴雨天气．但是在中国南方地区会有小雨。
It shows that it will be sunny in most part of China for each day in five days: Mainly clear skies. High around 85F.
