中文拼音 [yīntiānlǜ]
陰天率
英文
cloudy day factor-
The abnormal most times of precipitation of the two areas of jiangsu is similitude during 1st. - tth. october, but the non - precipitation times of the south of jiangsu is less than the north of jiangsu. the frequency of the persistent rain weather and the persistent sun weather is almost
兩區單獨出現連陰雨、連晴天氣以及全省出現連陰雨、連晴天氣的頻率相當，蘇南地區單獨出現連晴天氣、全省連晴天氣和蘇北地區連陰雨天氣的出現頻率要高於五一期間。The abnormal most times of precipitation of the two areas of jiangsu is similitude, but the abnormal little times of precipitation of the south of jiangsu is more than the north of jiangsu. the frequency of the persistent rain is high and the frequency of persistent sun is low in north of jiangsu, while it is contrary in south of jiangsu
兩區連陰雨、連晴天氣出現頻率也有較大差別：蘇北地區出現連晴天氣的頻率較高，單獨出現連陰雨天氣可能性較小，而蘇南地區易出現連陰雨天氣，很少出現連晴天氣，此外全省范圍連陰雨天氣的出現頻率也較高。There will be a great future if we integrate solar energy utilization techniques into heat pump techniques. on the base of integrating the two techniques, the paper analyzed the art trait of heat pump water heater, the manner of integration, the essential theory ; and developed a small capacity direct expansion solar - assisted heat pump water heater, and tested its thermal performance on the condition of different weather such as sunshine, overcast sky & night. the results make clear a small capacity direct expansion solar - assisted heat pump water heater can absorb not only solar energy but heat energy in air ; it takes on favorable thermal performance, on the condition of different weather such as sunshine, overcast sky & night, coph is about between 3. 5 ~ 5. 0, eer is about between 2. 5 ~ 4. 5, these are better than traditional air source heat pump water heater and non - direct expansion solar - assisted heat pump water heater, and it takes between 2 and 3 kwh to heat 270 kg water from 20 c to 50 c, it is very great in terms of saving energy and protecting environment,
本文在結合太陽能利用與熱泵技術的基礎上，分析研究了太陽能熱泵熱水系統的技術特點；太陽能集熱系統與熱泵系統的結合方式；直接蒸發式太陽能熱泵熱水系統的基本理論；研製出小功率直接蒸發式太陽能熱泵熱水系統樣機，並在晴天、陰天、夜晚等不同的天氣情況下對其進行了試驗，實驗結果表明：本小功率直接蒸發式太陽能熱泵熱水系統不但可以有效地吸收太陽能，還能有效地吸收空氣中的能量，具有良好的熱性能，在不同的天氣情況下，其制熱系數cop _ h大約在3 . 5 5 . 0之間，優于傳統的空氣熱泵和非直接蒸發式太陽能熱泵熱水系統：其效能比eer大約在2 . 5 4 . 5之間，將270kg水從20加熱到50隻需用電2 3度，節能及環保效果明顯。The temperature stress made the cells optimal irradiance range narrow and also made their sensitivity to irradiance. study on the daily variation of photosynthesis in different weather in four seasons in a year was carried out, too. the results showed that the daily variation curves of s1, s2 and s3 were two - peak curves in high irradiance, and the higher the irradiance was, the earlier the first peak appeared. in the weather with low irradiance ( for example, in cloudy day ), the photosynthetic rate varied with the irradiance changing
四季溫室不同天氣（晴天、多雲天氣和陰天）螺旋藻光合速率日變化測定結果顯示，在光照較強的天氣（如晴天） ， s _ 1 、 s _ 2和s _ 3的光合速率日變化曲線呈雙峰曲線，且光照越強，峰值出現越早；在光強較弱的天氣，光合速率隨光強的升降而升降。In addition, temperature drops, cloudy days, and rains and so on all caused the reduction of frequency of pollination
此外，氣溫下降、陰天降雨等都能使訪花昆蟲的訪花頻率降低。分享友人
