摘要
本文介绍在室温下时滞法测定蔗糖转化反应速度常数并与现行物理化学实验教材中数据处理方法处理的结果进行比较，阐述该方法的可靠性和优点。
The article introduces rate constant measurement of hydrolysis reaction of su-crose by time-lag method at room temperature and compares the result of this method withthe result of caculated from the method in textbooks of physical chemistry experiment, ex-pounds the reliability and advantage of the method.
