刻度吸管-
（NH4）2S2O8与KI反应速率常数与活化能测定实验微型化，把量筒量取改为微量刻度吸管，既保证了结果的准确，又节约了大量药品，与常规实验比较，结果满意。
The micromation of determined experiment for reactive rate constant and activation energy of ( NH 4 ) 2S 2O 8 is not only good for the correction of results , but also for saving reagents . Compared with general experiment , the micromation experiment can obtained the satisfactory results .
