絕熱轉化 的英文怎麼說
中文拼音 [juérèzhuǎnhuà]
絕熱轉化
英文
adiabatic conversion-
For xlpe insulated power cable, either chemical method or physical method is employed to transform the molecular structure of pe from chain into three - dimensional network, i. e. thermoplastic pe is transformed into thermosetting xlpe. after cross - linking, the thermal and mechanical properties of pe have been greatly improved while its excellent electrical property are still retained
交聯聚乙烯絕緣電力電纜是採用化學方法或物理方法,使聚乙烯分子由線形分子結構轉變為三維網狀結構,由熱塑性的聚乙烯變成熱固性的交聯聚乙烯,從而提高了聚乙烯的耐老化性能、機械性能和耐環境能力,並保持了優良的電氣性能。Then introduce berry ' s work of finding phase factors including quantum phase factors accompanying adiabatic changes, on the base of this, discuss berry phase factors of spinl / 2 particle in rotating magnetic field
本文接著介紹了berry1984年發現幾何相因子的工作,內容包括從量子絕熱定理推導berry幾何相因子。在此基礎上,把旋轉磁場中自旋1 2系統作為研究對象,對其幾何相位的變化特點進行了討論。Power plants converse elementary energy into electric power most of which are coal - burned power plants with a efficiency from 25 percent to 40 percent because of technology limit. as competition mechanism has been introduced into electric market and the identity of electric production, cost competition become the essential competition in electric market at present
發電廠是將一次能源轉換成二次能源的企業,在我國,絕大多數電能是由火電廠生產的,總體能耗成本十分高,受熱機技術的限制,燃料的化學能轉換成電能的效率不高,僅在25 ? 40之間。The effects of reinforcing particle size on deformation strengthening and localization behavior of sicp / 2024al composites are investigated by making use of split hopkinson compression bar and hopkinson torison bar. the experimental results demonstrate that the strengthening effect for the small - size particle - reinforced composite is higher than that for the large - size particle - reinforced composite
實驗表明:這類復合材料無論是在沖擊壓縮還是沖擊扭轉載荷下其變形強化和局部化行為都具有明顯的顆粒尺寸效應,即增強顆粒尺寸越小,變形強化效果越好,越易發生絕熱剪切變形局部化失穩。分享友人
