  1. There are many advantages to heat by air condition system, but there are also many problems. the air distribution of air condition room is often designed according to the summer outdoor parameters. thus, in winter, the hot air will arise with the influence of buoyancy, which result in the decline of vertical temperature gradient and produce a successive of problems

    空調送風供暖有著很多的優點,但也出現了很多問題,由於空調房間的氣流組織一般是以夏季工況為設計工況,在冬季由於送風熱氣流在浮升力作用下上升,引起垂直溫度梯度的增加,並產生一系列的問題,致使空調房間冬季室內熱舒適性較差、能源利用效率較低。
  2. In crystal growth experiment, aggas2 crystal was growen in special quartz ampoule by crucible descending method ( b - s method ). the equipments were used, which consist of a two - zone vertical growth furnace whose temperature gradient is tunable, a descending device with decelerating rate of 1 : 2000, a controlling system of electy and a temperature testing system using thermal couples

    晶體生長實驗中,我們利用上下溫度梯度可調的二溫區管式生長爐, 1 2000減速比的旋轉下降系統,電氣控制系統和密集適時測溫系統等,在特殊形狀的石英生長安瓿中,採用坩堝下降法( b - s法) ,以合成的aggas _ 2多晶原料進行晶體生長。
  3. 4, it has shown, through the study on the temperature modeling of ertan reservoir, that the location of upstream boundary can not be placed on the section with a great temperature gradient in vertical, because the water temperature distribution at upstream boundary can control the temperature structure in reservoir

    4 .在二灘水庫水溫模擬研究的基礎上對入口邊界的設定作了初步的研究,認為入口邊界不適宜選擇垂向溫度梯度較大的斷面。這是因為入口水溫垂向分佈基本控制了庫區水溫的分層狀況,而且入口邊界的速度和溫度條件的不匹配會導致較大的誤差。
  4. The article quantitatively analyses the winter hot air ' s distribution regulation in the human work region and reveals the regulation of temperature gradient forming and change and the influence to human thermal comfort. after test research, it clarifies the thermal characteristic regulation of indoor environment in winter air condition room. the mainly characteristic regulations are the over - great vertical temperature gradient and the over - low mean radiation temperature of air condition room

    本文對現有實際空調房間冬季熱射流在人體工作區的規律做出定量化分析,揭示了其溫度梯度形成變化的規律及對人體舒適的影響,經過測試研究明確冬季空調房間室內環境存在的熱特性的規律,其中房間的垂直溫度梯度過大、空調房間的平均輻射溫度較低是其主要熱特性規律。
