同位素示踪法是利用放射性同位素作为示踪剂对研究对象进行标记的微量分析方法。打个比方:就是把示踪原子派出去当“侦察兵”,或者说让它去跟踪。示踪原子可以让许多人们以前无法观察到的事情和物质“原形毕露”。使用“示踪原子”可以发现母鸡下的蛋不是由它们刚吃下肚的食物? Isotope tracer method is a microanalysis method that uses radioisotope as a tracer to mark the research object. An analogy, for example, is to send a tracer atom to a “scout” or let it track. Tracer atoms can make many things and materials that people could not observe before. Using the “Tracer Atom” you can see that the eggs under the hens are not the ones they just ate?
