The reactionextents and kinetic constants are calculated by peak-arearatio method.
利用峰面积比值法，计算了不同时间下的反应程度和动力学常数。

The fingerprints of Shenmai injection was established by HPLC, and the relative retention time and peakarearatio of each common peak was determined.
采用高效液相色谱法建立其指纹图谱，确定各共有峰的相对保留时间和峰面积比值。
