摘要

本文介绍了在400kV高压倍加器上，利用

F（р，

αγ

）

O瞬发核反应测量国内150余种茶叶样品含氟量的原理及实验装置，给出了一批典型的测量结果。结果表明：同一品种的茶叶，茶的品级数越大，含氟量越高；茶叶的品种越好，含氟量越低。

Abstract

Experiments of

F (

αγ

)

O prompt nuclear reaction analyses of tea F contents were performed on a Cockroft-Walton accelerator. The principle and apparatus are described. More than 150 varieties tea samples were examined. Results show that for the same variety of tea samples

the higher the grade of the tea

the higher the F concentration it contains

and for different varieties

the better the tea

the lower the F concentration of the tea.
