元素釷
英文
th-
Thorium tungsten electrode is the most commonly used tungsten in america and some other countries and is a good general use tungsten. especially, it performs well when overloaded with extra amperage
釷鎢電極使用很普遍,釷元素雖具有低輻射性,但它相對純鎢來說,已經體現出重要的改進性能。Since the unstable nuclei exist between actinides, including thorium and stable nuclei like lead and bismuth, explosive events such as supernovae are required to produce actinides
自不穩定核之間存在著錒系元素,包括釷和穩定核像灌了鉛,鉍,爆炸性事件,如超需出示錒Their discovery marks the first abundance determination of the actinides element thorium in a star beyond the milky way, and follows the detection of thorium in more than ten stars within the milky way
他們發現,標志著首豐測定的錒系元素釷星以外的銀河系,跟檢測釷十余恆星的銀河系The team ' s measurement of thorium revealed the overall abundance pattern of heavy elements for this object
該隊的測量發現釷的總體格局豐富的重元素,為這個目的A few elements, among them uranium and thorium, spontaneously disintegrate into lighter elements by chances.
少數元素,其中有鈾和釷,通過它們核的變化自然蛻變成較輕的元素。I was struck by the fact that the activity of uranium and thorium compounds appears to be an atomic property of the element uranium and of the element thorium
我突然意識到,鈾化合物和針化合物的這些活性似乎是元素鈾和元素釷的原子屬性。Surprisingly for astronomers and nuclear physicists, the abundance ratios of thorium to other heavy elements are very similar to ratios found for milky way stars
出乎意料的天文學家和核物理學家豐比率釷等重元素非常相似比率發現銀河系恆星The data of natural gamma ray spectrum logging are of well conformity with the contents of thorium, uranium and potassium obtained by surface gamma ray survey, laboratory analysis and aerial gamma ray spectrum survey
對自然伽馬能譜測井儀、地面伽馬能譜、室內分析、航空伽馬能譜測量的同一地點釷、鈾、鉀元素含量進行對比分析得知,各種方法所得結果具有較好的一致性。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
