中文拼音 [huánzhōusǔnshī]
環周損失
英文
annulus loss-
We calculate a model with angular momentum loss caused by gravitational radiation, and find that the binary undergo cyclic evolution as well. however, the period of the cycle becomes shorter, and the ratio of the time spent in the semi - detached phase to the time spent in the contact phase in a cycle becomes smaller
我們計算了由引力波輻射引起雙星系統的角動量損失的演化模型，發現雙星系統還是經歷循環演化，不過循環的周期變短，且雙星系統的每一個循環處在半接狀態的時間與處在相接狀態的時間之比變小。4. through the galvanostatic charge / discharge experiments with different schedules, it was found that mn ( ) / mn ( ) in acidic media as half - cell in a novel redox flow system is practically feasible in that it has such advantages as low cost, high open voltage, a certain coulombic efficiency with low charge / discharge current, and long cycling life. in the second part, cosn alloy and cu - sn samples were synthesized firstly by h2 - reduction following solid - state reaction between co ( ii ) 、 cu ( ii ) 、 sn ( iv ) 、 and naoh at ambient temperature
並研究了其分別作為鋰離子電池陽極材料在1mol / llipf6 / ec + dmc電解液中的恆流充放電性能，各樣品均存在較大的首次不可逆容量損失； 10個循環內cu - sn可逆放電容量可保持在280mah / g以上，而第十周時cosn 、 cu6sn5的可逆放電容量分別為50mah / g和60mah / g 。In order to analyze the influence of airplane noise on indoor sound environment in the vicinity of beijing international airport, different of buildings, such as villages, schools, offices, commercial building are choose as monitoring objects, the characteristic of sound insulation for building around beijing international airport are monitored and analyzed
摘要為較好的分析飛機噪聲對機場周圍居民室內聲環境的影響，研究選擇不同類型的民居房、學校（多層建築） 、基層機關辦公用房、商品房等為測試對象，對北京國際機場周邊地區建築物隔聲特性（插入損失）進行監測與分析，結果表明：現有民居、學校、機關辦公室的隔聲特性較差，商品房的隔聲效果較好。After a discussion of the heat transfer condition of the chilled water pipe which is installed in tunnel, the relation between the temperature of the chilled water and its transportation distance, the author holds that a central refrigeration system shall be adopted, and the loses of chilled water temperature in a long transportation distance could be overlooked on the condition that the pipe is heat insulated
摘要分析了冷凍水管沿地鐵區間隧道敷設時與周圍環境的換熱狀況；認為採用集中供冷的方式，在隔熱情況下可不?慮冷凍水因長距離輸送而引起的溫升損失。The mechanism of arc eroding for cuw60 / crcu integrated contact is the volatilization of cu under the arc working, then the particles of w were worn off the matrix, this phenomena is n ' t formed continuous skeleton during the connecting and cutting. such - and - such repeating resulted in the arc erosion of the contact, until invalidation
（ 1 ） cuw60觸頭的燒損機理是以cu首先熔化噴濺，然後沒有形成連續骨架的w顆粒在關合的磨損中脫落，這是一個燒損周期，如此的循環導致觸頭的燒損，直至失效。分享友人
