The result was used to adjust relative humidity and to enhance the ability of mm5 mesoscale modeling system to produce accurate forecast of precipitation. we define the air condition includes 5 kinds : the clear sky, semitransparent or fractional cloud, high cloud and low cloud and middle cloud. in this process, we present the method development for the generation of cloud based on gms - 5 images. mm5 ( fifth - generation perm. state / near mesoscale model ) output will be extensively used for the off - line computation of dynamic changeable mutispectral thresholds in order to adapt to variable weather using statistical regressive relations produced by optimal regressive analysis
基於常規地面觀測資料，將天空狀況分為晴空、半透明雲或碎雲、高雲、中雲和低雲5種情況，用最優回歸分析法對mm5模式的三維要素場和常規地面觀測資料進行統計分析，得出雲判別和雲分類的衛星雲圖多譜閾值的統計關系統計回歸判別方程，對衛星雲圖進行雲判別和雲分類，據此得出mm5中尺度數值模式初始場各點的雲分佈，並對模式初始場的相對濕度進行調整，以達到改善中尺度數值預報模式預報結果的目的。 -
The mathematics model among the time of sky window, carrying capacity and traveling speed is made in this paper. " v - mode sky window " and " plumb sky window " is deeply researched, the influence rule is found, and the conclusion is made. in addition, the paper discusses the feasibility of large maintenance machinery in rail whirl trunk, put forward the construction condition, the measure and attentive proceeding
論文主要針對大型機械施工，通常採用的「 v型天窗」和「垂直天窗」 ，分別從它們各自對線路通過能力和列車旅行速度兩個方面，通過建立天窗時間與能力扣除和速度系數之間的數學模型，對其進行了深入的討論和研究，並最終找到了它們之間的影響規律，得出了結論。 -
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 daily variation of surface o3 is different under different weather condition, the variation of surface o3 in spring, autumn and summer is almost same when it is clear. in spring and autumn, under the condition of clear sky, its value is higher than that in cloudy or rainy / snowy day, while its variation is not obvious in winter and summer ; in rainy and snowy season, the variation of surface o3 in spring, autumn and winter is insignificant, bnt in summer, it is significantly different from other seasons, daily difference is the highest among all seasons, it has some important relationship with rain / snow, moreover, the function of rain and snow to the varation of surface o3 is different
（ 2 ）不同天氣條件下，春、夏、秋、冬四個季節地面o _ 3濃度變化不盡相同，晴天和多雲天，春、夏、秋季的地面o _ 3變化趨勢基本一致，其中，春秋季，晴天o _ 3值高於多雲天和降雨天，而冬季和夏季則不明顯；各季節降雨、雪天o _ 3濃度的變化情況來看，地面o _ 3在春、秋、冬三個季節變化不大，而夏季與其它季節明顯不同，變化幅度很大，日較差在四個季節中為最大，這與降雨、降雪關系很大，並且可能存在雨、雪的差異。 -
