氣體焓 的英文怎麼說
中文拼音 [qìtǐ]
氣體焓
英文
gas enthalpy-
Adiabatic throttling process of gas is not isoenthalpic
氣體的絕熱節流過程不是等焓過程Standard practice for measuring plasma arc gas enthalpy by energy balance
用能量平衡法測量等離子體電弧氣體焓的標準實施規程Because of the small conductivity factor of organic phase change materials, all kinds of copper grids, gas sio2 and organic bentonite were added to organic phase change materials in order to heighten its conductivity factor. the conductivity factors were maesured by using time - temperature curve and comparison curve, and, the conductivity factor curves were drawn. at the same time, the entropy of phase change of every system was determined by using dsc
針對有機相變貯能材料導熱系數小的缺點,採取在其中添加各種形狀的銅網格、氣相sio _ 2和有機膨潤土的方法來改善體系的導熱性能,利用時間-溫度曲線法和比較法兩種方法測定體系的導熱系數,並且繪制了體系導熱系數的變化曲線;同時利用dsc對上面部分體系的相變焓進行了測定。There are great differences between ground test of a flight vehicle ' s aerodynamics and that of a dual - mode scramjet when ground test facilities are used to do experiments on a dual - mode scramjet engine, the components of incoming flow and its parameters, including total pressure, total temperature ( or total enthalpy ) and velocity must be simulated. at the same time, since the fuel ' s resident time within a combustor is very short, on the order of one millisecond, it is difficult to measure the flow - fields
進行雙模態沖壓發動機地面試驗研究時,必須要求試驗設備能模擬實際飛行條件下來流氣體的組分、總壓、總溫(或總焓)以及來流氣體的流動速度;同時由於燃料在燃燒室內駐留的時間很短,一般為毫秒量級,從而使流場物理量的測定顯得非常困難。The calculation determined the main point defect under different cd pressure and the reaction enthalpies and entropies and the equilibrium constants in ( cd, zn ) te according to the quasi - chemical equations written for cdte sublattice. also the recipe of two - zone annealing process for cd0
根據計算結果,確定了不同氣氛條件下cd _ ( 1 - x ) zn _ xte ( x = 0 . 05 )晶體中佔主要地位的點缺陷和相關偽化學反應式的反應焓、反應熵及平衡常數,給出了兩溫區本徵退火的具體參數。The balanceable piston theory and perfect gas model are used as building block to design tunnel, and the resulting tunnel can generate uniform flow, which can provide long experimental time with high mach number, given enthalpy and reynolds number, thus, the scramjet and ramjet aircraft can be studied in this tunnel
採用理想的平衡活塞運行理論和完全氣體模型,該風洞可以產生高馬赫數、一定焓值和re數、實驗時間較長的均勻流動,滿足超燃、亞燃現象的研究。分享友人
