  1. Although the knowledge of wind effects on tall buildings has significantly improved over the last decades, an understanding of the mechanism that the atmospheric flow field to various wind include effects on structures has not been developed sufficiently for formulation of functional expressions. not only is the wind approaching a building complex, but the flow pattern generated around a building is complicated by the distortion of the mean flow field, the flow separation, the vortex formation, and the wake development

    在過去的幾十年裡，雖然人們對高層建築風效應的了解已有顯著提高，但對大氣流場與結構物各種風致響應的關系還不能用解析表達式加以描述。由於平均流場的奇變、流動分離、旋渦形成以及紊流的發展，不僅使得流向建築物的風，而且使得繞建築物的流譜變得十分復雜。
  2. A model of letting out of no oil ubricated double whirlpools vortex air compressor was set up, the length of leak line of one cycle was calculated the change of the leak line at work, the change of the length of leak line varying with the crank corner, and the change of the leak amount varying with the pressure of revealing atmospheric and crank corner were analyzed

    摘要建立了無油潤滑雙渦圈渦旋壓縮機的泄露模型，根據型線的幾何理論計算了一個周期內泄漏線的長度，分析了在工作過程中泄漏線的變化，泄漏線長度隨曲柄轉角的變化，以及泄露量隨排氣壓力，曲柄轉角的變代情況。
  3. 4, the summer rainfall anomaly in northeast china bears close correlation with the atmospheric circulation backgroud. while cold air in middle and high levels of troposphere is active in wet year with the positive anomalies over high - latitude and polar area, the active longwave ridge, the anomalous long - wave ridge in northeast china and inner - mogolia as well as the northward and eastward of the polar vortex, the contrary is in the dry year in northeast china

    4東北地區夏季降水異常與大氣環流背景有密切的關系，東北地區夏季多雨年在對流層中、高層冷空氣比較活躍，高緯和極區主要由位勢高度的正距平所控制，貝加爾湖以北的地區長波脊較為活躍，在東北地區和蒙古地區有異常的長波槽發展，極渦位置偏北、偏東；而在東北地區夏季少雨年則容易出現與上述相反的異常環流形式。
  4. By using multi - channel observations of olr, hirs - tb12, erb, vis, ssmr and ssm i on the us satellites, it is analyzed that the global general atmospheric circulation features related to the anomaly of cold vortex over northeast china and it s premonitors are also revealed. it is found that there is an effected chain, which consists of sea ice over northern hemisphere, sea surface temperature in the mid - east equatorial pacific, asia monsoon and local budget of earth radiation in northeast china, on the anomaly of northeast cold vortex. the impacts of each factor in the chain are discussed. the results indicate that the applications of multi - channel satellite observations on research of climate change are of significance

    利用美國氣象衛星olr ， hirs - tb12 ， erb ， vis ， ssmr和ssm i多通道的觀測資料，分析了東北冷渦異常年的全球大氣環流特徵及其關鍵地區的先兆特徵對于東北冷渦異常，發現了有一個由北半球的海冰，赤道東太平洋的海溫，亞洲的季風以及東北地區地氣系統輻射收支組成的影響鏈存在。由此討論了影響鏈上的各因子對東北冷渦異常的作用。結果表明多通道衛星觀測資料的綜合應用在氣候變化的研究和預測中有著重要的意義。
