stable isotope

基本解釋

What is the lightest element on Earth, with no stable isotope?
地球上沒(méi)有穩(wěn)定同位素的最輕的物質(zhì)是什麼？
The highest known magic number for neutrons alone is 126. Lead, with 82 protons and 126 neutrons, is thus “doubly magic” and the heaviest stable isotope in the periodic table.
目前已知的最大中子數(shù)是126，82個(gè)質(zhì)子和126個(gè)中子組成了元素周期表中最重最穩(wěn)定的同位素。
Although the easier ionization of radon leads one to expect the most extensive chemistry for that element, the high instability of even the most stable isotope has severely limited studies of it.
氡容易離子化，這讓人期望，該元素有最廣泛的化學(xué)反應(yīng)，但是，這個(gè)元素最穩(wěn)定的同位素也極不穩(wěn)定，這使氡的研究受到了嚴(yán)重的約束。

The uranium in the cake is almost entirely the stable isotope uranium 238.

穩(wěn)定同位素
DNA stable-isotope probing(DNA-SIP) is a recently developed method with which the incorporation of stable isotope from a labeled substrate is used to identify the function of microorganisms in the environment.
DNA穩(wěn)定同位素探針(DNA-SIP)是一種新興的技術(shù),通過(guò)將同位素穩(wěn)定結(jié)郃到特定的底物來(lái)確定環(huán)境中微生物的作用。
穩(wěn)定碳同位素
穩(wěn)定性同位素

穩(wěn)定同位素
A comprehensive study of oxygen,hydrogen and carbon isotope geochemistry has been carried out for ultrahigh pressure metamorphic rocks in the Dabie orogen. A number of stable isotope anomalies have been discovered for the rocks.
通過(guò)對(duì)大別造山帶超高壓變質(zhì)巖的氫、氧和碳同位素地球化學(xué)研究，發(fā)現(xiàn)了顯著的穩(wěn)定同位素異常。
