鈾外殼 的英文怎麼說
中文拼音 [yóuwàiké]
鈾外殼
英文
uranium jacket-
It is important that study gamma - ray spectrometry of field rock and soil in the earth ' s crust. its energies range between 30kev and 3000kev, where there is much information of natural radioactive nuclides, such as uranium, thorium, potassium, and information of artificial radioactive nuclides, such as cesium, americium, cobalt, and information of the results in interaction between gamma - ray and earth ' s crust
研究表明：野外地面射線能譜測量主要研究地殼巖石土壤中產生的能量約為30kev 3000kev的射線，這裡面包含著鈾、釷、鉀等天然放射性核素信息，核工程活動產生的大量人工放射性核素信息以及射線與地殼相互作用產生的相關信息。This paper introduces the latest progress of high level radioactive waste disposal programs in the world, and discusses the key scientific issues as follows ： ( 1 ) the precise prediction of the evolution of a repository site ; ( 2 ) the characteristics of deep geological environment ; ( 3 ) the behaviour of deep rock mass, groundwater and engineering material under coupled conditions ( intermediate to high temperatures, geostress, hydraulic, chemical, biological and radiation process, etc ) ; ( 4 ) the geochemical behaviour of transuranic radionuclides with low concentration and its movement with groundwater : and ( 5 ) the safety assessment of disposal system
在介紹國內外最新研究進展的基礎上，重點討論高放廢物地質處置的若干關鍵科學問題：處置庫場址地質演化的精確預測、深部地質環境特徵、多場耦合條件下（中（高）溫、地殼應力、水力作用、化學作用、生物作用和輻射作用等）深部巖體、地下水和工程材料的行為、低濃度超鈾放射性核素的地球化學行為與隨地下水遷移行為及處置系統的安全評價。Because of the upper limit of the nuclear density, which prevents the core to compress too far, the collapsing inner core will bounce back outwards. this out - going inner core will collide with the in - coming outer core, which is collapsing rapidly. this collision will send off shock waves and create heavy elements, like uranium
由於原子核的天然密度會成為巨大的阻力，防止核心進一步收縮，這時核心會猛烈反彈，以極高速塌縮的核心外殼會和反彈中的核心碰撞，產生強烈的沖擊波，同時產生出像鈾等比鐵更重的元素，並把恆星外殼炸毀，這便是Even without these man made sources of radiation, exposed to natural background radiation. the rocks and soil of the earth s crust contain variable amounts of natural radioactive elements such as uranium and thorium. this varies with geography - for example the hottest places in britain are cornwall and around aberdeen
就算排除人為輻射，人類會在天然環境中接觸到本底輻射，如地球外殼的巖石和泥土含有份量不同的輻射元素如鈾和釷，而份量視乎地理位置，如英國的康瓦爾和阿伯丁郡最為熱點。分享友人
