active potassium dating method的用法和样例：
- Fluoroaniline is synthesized in two steps from p-nitrochlorobenzene and active potassium fluoride.
- The second dating method was palaeo-magnetic analysis, or magnetic polarity stratigraphy.
- The 14C age dating method was applied to study the deposited age of the Jiangbei conglomerate in Youxi profile,Jiangjin. The geochemical characteristics of oxides such as MgO,CaO,Fe2O3,FeO,Fe2O3/FeO were analyzed.
- The longer tratspornation distance of the fluvial deposits facilitates the bleaching and increases the reliability of the luminescence dating method, especially for the young material.
