There are two main types of uses of radioactive isotopes in biochemistry.
在生物化學中,放射性同位素主要有兩方面的應用。Standard test method for isotopic uranium in water by radiochemistry
用放射化學法測量水中同位素鈾的標準試驗方法Isotopes, including both radioactive and stable isotopes, make important contributions to development of society and economy, and progress of science and technology in usa
摘要同位素,包括放射性同位素和穩定同位素,對美國社會和經濟發展、科學技術進步做出了重要貢獻。Scientists already know the ages of the mare flows at the apollo sites from analyzing the radioisotopes in the rock samples, so they can estimate the ages of other flows by comparing their crater densities with those of the landing - site flows
科學家分析巖石樣本中的放射性同位素,已經知道阿波羅登陸點的月海巖流年齡;因此將其他巖流的隕石坑密度與登陸點巖流的隕石坑密度相比,科學家便能估計其他巖流的年代。In addition, researchers have shown that low - cost laser accelerators are suitable for many of the same applications as conventional accelerators, such as producing short - lived radioisotopes used in medical diagnostics and generating neutron and positron beams for studies of materials
此外,研究人員也證明,在許多應用上,廉價的雷射加速器都跟傳統加速器有同樣的功用,例如用來產生醫學診斷用的短生命期放射性同位素,或製造檢測物質用的中子與正子束。Inorganic chemicals ; organic or inorganic compounds of rare - earth metals, of radioactive elements or of isotopes
無機化學品;稀土金屬,放射性元素及其同位素之有機及無機化合物Among them the x - ray diffraction analysis is mainly used to confirm clay mineral assemblages and their crystallinity ; chemical analysis and electronic microscope are used to study the source, the genesis and the evolvement process of clay minerals ; radioactive isotopes analysis can make up the relationship between the time and space which is based on the climate index and the chronology ; hydrogen and oxygen isotopes also provide important evidence for reconstructing paleoclimate
其中, x射線衍射分析主要用來確定黏土礦物組合及其含量以及某些黏土礦物的結晶度化學分析電鏡分析主要用於黏土礦物的來源成因演變過程的研究放射性同位素的研究使氣候指標和年代學建立起時間和空間上的聯系而氫氧同位素分析亦能對古氣候重建提供重要佐證。These effects have been confirmed in highly sensitive experiments, and relativity is now a basic, everyday tool of experimental physics : particle colliders take advantage of the increase in mass and lifetime of fast particles ; experiments with radioactive isotopes depend on the conversion of mass into energy
這些效應已經由高靈敏度的實驗證實,而且相對論現在已成為實驗物理學基本的日常工具:粒子對撞機利用增加快速粒子的質量與生命期來進行實驗;放射性同位素的實驗則依靠質量轉變成能量。分享友人
