熱脹升高 的英文怎麼說
中文拼音 [rèzhàngshēnggāo]
熱脹升高
英文
thermal rise-
Suction gas pressure goes up as the compressor run at the lower speed in the lower burthen, and this is beneficial to lower systems energy - consume. when the system is controlled by wvf, the discharge change of the evaporator is not linear ; the electronic expansion valve is adopted to regulate the system superheat degree, and the controlled object is parameter time varying, accordingly, the time varying controller should be adopted
在負荷較小時，壓縮機採用低速運轉，吸氣壓力升高，這對系統降低能耗是有利的；變頻控制時，蒸發器製冷劑流量的變化並非線性；系統中採用電子膨脹閥進行過熱度控制，被控對象具有參數時變的特性，相應地宜採用變結構的控制器。Eev should be selected for various refrigeration systems according to the thermal properties of refrigerants ; the discharge coefficient of eev is sensitive to the aperture and impulse quantity of eev ; when the eev structure is made, the discharge coefficient goes up with the lowering of evaporation temperature or goes down with the hoisting of the condensation temperature. it is le
對于不同工質的冷藏集裝箱製冷系統，電子膨脹閥應該根據具體製冷劑的熱力性質選取；電子膨脹閥流量系數對孔徑和脈沖數比較敏感；在結構固定時，流量系數隨蒸發溫度的降低而升高，隨冷凝溫度的增加而增大，受過冷度變化的影響較小；電子膨脹閥的容量受孔徑影響最大。But it also includes two fatal disadvantages : first, at is difficult to be sintered and its density is low, which causes its lower strength ; second, in the temperature range of 1023 - 15 73 k, at can decompose into al2o3 and tio2 easily, which can cause the stress concentrated and raise the heat expansion rate
但是該材料本身存在的兩大致命的缺點，在很大程度上限制了它的廣泛應用： （ 1 ） 、鈦酸鋁難以燒結，燒結體的緻密度低，因而強度不高； （ 2 ） 、在750 1300的溫度范圍內易分解成氧化鋁和二氧化鈦，造成材料內部應力集中，並使材料的熱膨脹率升高。Transverse cte of c / sic composites increases linearly, changing in a similar way with that of cvd sic in low temperature range ( < 900 ), and decreases fast in high temperature range ( > 900 ), then increases again at 1200
其徑向熱膨脹在低溫區域（ 900 ）內線性增加，與cvdsic的熱膨脹十分接近，在高溫區域（ 900 ）內迅速降低，並在1200急劇回升。1. the splitting from the binding interface of cuw / crcu roots from the rich cr and the oxidation of the binding interface, which leads to the higher thermal resistance in binding interface than normal, and the thermal stress enhanced. the extruded cu is suggested to instead of casting cu
（ 1 ）斷裂是由於原材料鑄態的crcu中c :質點大於熔滲的孔隙而沉積在界面上，同時在有氧源存在的條件下，結合面氧化，致使結合面結合不好，界面熱阻升高， cuw與crcu部分的膨脹不同，應力集中，燃弧后斷裂。As far as the sandstone adopted, the effect of effective stress on permeability lies in pressure effect of effective stress on pore and throat, and that of temperature lies in aggravating disaggregation of clay mineral with rising temperature and pressure effect of skeleton expansion on throat
就本試驗所用砂巖而言，有效應力對滲透率的影響主要在於有效應力對孔隙，尤其是對喉道的壓縮作用；而溫度對滲透率的影響則主要在於隨溫度升高而加劇的粘土礦物的分散作用以及砂巖骨架的熱膨脹對喉道的壓縮作用。In summer, intense solar heating leads to scorching temperatures over the asian land masses. as a result, the overlying air heats up, expands and rises upwards. this leads to the formation of a semi - permanent low pressure area near the heart of the continent
在夏天，亞洲大陸受到太陽的強烈照射，地面溫度升高，其上的空氣受熱，於是膨脹和上升，一個長期維持的低壓區便在亞洲中部形成。5. schapery model can be used to calculate the cte of composite when temperature is lower ( 50 - 100c ) and kerner model can be used when temperature is higher ( 300 - 450c ). the cte of composite will increased more quickly than that by three models when temperature is between ( 100 - 300c )
復合材料的熱膨脹系數在溫度較低（ 50 100 ）時可用schapery模型計算，在高溫（ 300 450 ）時可用kerner模型計算，在100 300之間則隨溫度升高增加的很快，且與所有模型分析結果不一致。分享友人
