The stable isotopic research is established by studying the discrepancy in isotope ratio , which was caused by isotope fractionation , and the isotopic ratio difference can be determined by mass spectrometer 稳定同位素的研究主要是建立在此同位素分化作用所造成的同位素比值差异，而此同位素比值差异可被质谱仪测知。
Inspection is to make an objectives observation of the patient ' s mental state , facial expression , complexion , physical condition , picture of the tongue and abnormal changes of excretions and secretions so as to predict the pathological changes of the internal organs and to understand the disease 老师：望诊，是对病人的神、色、形、态、舌象以及分泌物、排泄物色质的异常变化，进行有目的的观察，以测知内脏病变，了解疾病情况的一种诊断方法。
