裂變事件 的英文怎麼說
中文拼音 [lièbiànshìjiàn]
裂變事件
英文
fission event-
K - ar age of an illite from alteration rock in the contact zone around lianhuashan porphyry is 38. 6ma. with referencing to the main metallogenic period of yulong copper metallogenic zone and of ailaoshan gold metallogenic zone, it is suggested that the time of formation of deposits in the district studied is probably in a period of time from 38. 6ma at earliest to 20ma at latest. this time is equivalent to the origination time of two important tectonic events, i. e., lanping movement and the turning point when ailaoshan - red river fault turned from sinisteral into dextral
獲得了蓮花山巖體周圍接觸帶蝕變巖中伊利石k - ar年齡38 . 6ma ，參考玉龍銅礦帶和哀牢山金礦帶的主要成礦期（分別為30ma左右及26ma ） ，釐定本礦集區成礦年齡下限為38 . 6ma ，上限為20ma ，與兩次重要的構造事件?蘭坪運動的起始時間及哀牢山?紅河斷裂由左旋轉為右旋的時間相當。We ca n ' t divide the multiple streams time series into singleness times series simply in the research of multiple streams time series, we ' ll dissever the relation between the events of the multiple streams. although the msdd can find the dependency relationship of multiple streams, but it have n ' t the initialization of the events, the express of the time relationship between events is not frank, the cost of the algorithm is expensive ( o ( n5 ) ), i ca n ' t find much more knowledge in multiple time series, it find the dependency patterns only of the multiple time series, so there need a new more effective, frank, complete algorithm to find the knowledge
研究多流時序不能簡單地將它割裂為單流時序，因為這樣就割裂了數據流事件之間的關系。雖然msdd能夠發現多流時間序列中的依賴模式，但是由於其缺少對數據的初始化、事件之間時間關系的表示不直觀、演算法執行的時間空間開銷很大（ o （ n ~ 5 ） ） 、不能夠充分發現多流時間序列包含的知識，它只發現依賴關系，因此研究新的，高效，全面的發現多流時間序列事件之間關系的演算法成為必要。本文分析了單一和多流時間序列中的知識發現，把多流時間序列事件內部存在的關系表示為：關聯模式、依賴模式、突變模式。This in turn introduces chinese literary theory into the global context by which chinese literary theory has shaken off the trammels of the meta - narrative of historical totality but unfortunately entered three dilemmas : the disjunction between modern anxiety and self - identification, the displacement between ontological and strategic links, and the condensation of source documents and the expansion of the applied programs
現代性西學東漸使中國文論進入全球化語境，在這一語境中，漢語批評擺脫了總體性歷史元敘事的控制，但又遭遇到三方面的兩難處境：現代性焦慮與自我認同的裂變、本體論介面與策略性介面的錯位、源文件的壓縮與應用程序的擴張。The experiment was carried out at the lawrence berkeley national laboratory ( u. s. a ). a 252cf was placed at the center of the gammasphere detector array which, for this experiment, consisted of 102 compton - suppressed ge detectors. by measuring prompt - ray of spontaneous fission from 252cf, a total of 5. 7 1011 triple - and higher - fold coincidence events were collected
實驗工作是在美國洛侖茲伯克利國家實驗室（ lbnl ）的gammasphere探測裝置上完成的， 252cf自發裂變源放置在一個由102個反康ge探測器組成的gammasphere探測器陣列的中心，測量自發裂變產生的瞬發譜，記錄三重以上的符合事件。Crucible 416r should be forged at 2050 to 2150 f ( 1121 to 1177 c ) and finished above 1400 f ( 760 c ). crucible 416r is not adaptable to severe upset forging operations
在小弟我以前做事的鑄造工廠，只要是碰到3字頭與4字頭鑄件變形，都需要熱處理后才能整形.要不然內部會產生應力導致鑄件破裂If some way can monitor the inside state of the project structure ( mainly stress, strain and crackle ) real - time online, we can make the assessment to the security state of the engineering component real - time and reduce the loss of the accident remarkably
如果能夠實時在線地監測工程結構的內部狀態（主要是應力、應變和裂紋） ，就能夠實時地對工程構件的安全狀態做出評估，可以把事故的損失減到最小。Before rock failure, it is found that ae distributed densely, and the coming fracture will occur in the density center of high magnitude events, and ae ratio of frequency grows greatly. these precursors can be presented by the change of b value, a t value and the contour of v value. prefab crack systems in the specimen will affect the fractures hi rocks
關于巖石破裂過程中一些物理量的變化，發現在巖石破裂前，主破裂發生的區域先出現大能級聲發射的密集分佈；在巖石加載的臨界狀態，大能級的聲發射數量大量增加；在接近臨界時，大能級聲發射事件在失穩前頻度突然加快。分享友人
