( 3 ) the saturated temperature of refrigerant - oil mixture has different definitions because of the superheat temperature of the mixture . one is the real saturated temperature of the mixture and the other is the saturated temperature of pure refrigerant corresponding to the tested pressure of the mixture . in this paper , the heat transfer coefficients based on the two different saturated temperatures are compared and the results showed the latter is larger ( 3 )由于制冷劑含油混合物過熱溫度的存在,使其具有兩種不同的飽和溫度定義,一種是所測實際溫度,另一種是所測壓力對應純工質的飽和溫度,文中就這兩種飽和溫度定義下的冷凝平均換熱系數進行了比較,發現后者大于前者。

The conclusions reached are as follows : ( 1 ) the saturated temperature of refrigerant - oil mixture is higher than that of pure refrigerant at a same pressure . the temperature difference , which is called superheat temperature of refrigerant - oil mixture , increases as the oil concentration and the vapor quality are increased at a certain saturated pressure and pressure has negligible effect on the superheat temperature of the mixture 得出以下結論: ( 1 )制冷劑hc290含油混合物的飽和溫度高于相同壓力下純工質的飽和溫度,這個溫度差,也就是文中所謂的制冷劑含油混合物的過熱溫度隨混合物質量含汽率、含油濃度的增加而增加,而飽和壓力對過熱溫度的影響不大。

Abstract : based on the analysis of the mathematics models of saturation steam density and superheat steam density the paper states that the deviation of the detection on temperature highly affects the accuracy of intelligent flow totalizer . especially for saturation steam , the accuracy of the temperature detection circuit shall be designed higher than the accuracy of the instrument . thus a temperature detection circuit based on ratio method with high accuracy is introduced 文摘:在分析飽和蒸汽和過熱蒸汽密度的數學模型的基礎上指出,溫度檢測的偏差對智能流量積算儀的精度影響極大,尤其是飽和蒸汽,測溫電路的精度應設計為遠高于儀表的精度,同時引入一種基于比率法的高精度測溫電路。

The conclusions reached are as follows : 1 . the saturated temperature of refrigerant - oil mixture is higher than that of pure refrigerant at a same pressure . the temperature difference , which is called superheat temperature of refrigerant - oil mixture , increases as the oil concentration and the vapor quality are increased at a certain saturated pressure and pressure has negligible effect on the superheat temperature of the mixture 得出以下結論: 1 、相同壓力下,制冷劑hc600a含油混合物的飽和溫度高于純工質的飽和溫度,這個溫度差,在就是文中稱為的制冷劑含油混合物的過熱溫度,它隨混合物質量含汽率、含油濃度的增加而增加,而飽和壓力對過熱溫度的影響不大。

We make a theoretical analysis of the experimental results and draw some conclusions as follows : the saturated temperature r290 - oil mixture is higher than that of pure r290 at a same pressure . the temperature difference , which is called superheat temperature of refrigerant - oil mixtures , increases as the oil concentration and the vapor quality are increased at a certain saturated pressure and pressure has negligible effect on the superheat temperature of the mixture . ( oil concentration is 0 . 43 ? - 5 . 28 ? ) 并根據實驗結果進行理論計算,得出以下結論:天然制冷劑r290含油混合物的飽和溫度高于相同壓力下純工質的飽和溫度,這個溫度差,也就是本文中提到的所謂制冷劑含油混合物的過熱溫度隨混合物質量含氣率、含油濃度的增加而增加,而飽和壓力對過熱溫度的影響不大(含油率0 . 43 ? - 5 . 28 ? ) 。

The main results in this paper are as follows : ( 1 ) study on starting up performance of thermosyphon : according to the study on the states before and after starting up of thermosyphon with the various filling amount , it is considered that the phase change heat transfer inside the copper - water thermosyphon with a large ratio of length and diameter is not only influenced by the boiling degree of superheat , but also controlled by evaporation and companied with the boiling of the thin liquid film 本文的主要研究結果為: ( 1 )熱虹吸管啟動性能的研究:通過對從不同充液量、啟動前狀態、內部汽化核心狀態對啟動的影響所進行的試驗研究,認為大長徑比的銅?水熱虹吸管管內相變不僅僅為沸騰,而是以蒸發為主,伴有薄液膜的沸騰。

The analysis by sampling data of no . 2 caster bao steel shows that the integrated heat transfer coefficient is independent of the width of slabs , and the effect of superheat is not clear , but the effect of casting speed is very obvious 摘要對寶鋼2號連鑄機現場數據的采樣分析結果表明:連鑄坯在線寬度對結晶器綜合傳熱系數沒有影響。

The machine is low in revolution , stable in operation , not the superheat phenomena and will not produce the layer and education for the compound whose specific grvity and granularity , are different 本機轉速較低,運轉平穩,對熱敏性物料不會產生過熱現象,對比重懸殊和粒度不同的物料組成的混合物不會產生分層離析現象。

Power networks are polluted by harmonics , which do harm to electrical equipments ; cause devices superheat , generate vibration and noise . a more serious consequence is that devices are damaged 這些諧波對電網造成污染,給用電設備帶來危害,引起設備過熱、產生振動和噪聲,并使絕緣老化,嚴重時會損壞設備。

Student : sir , you can have lots of heat , even more heat , superheat , mega heat , white heat , a little heat or no heat . but we don ' t have anything called cold 學生:先生,你可以有許多熱能,甚至更多熱能,過熱,超多熱能,白熱,一點熱能或沒有熱能。但是沒有‘冷’ 。
