摘　　要：建立了准单能6—7 MeVγ射线参考辐射场并介绍了有关特性;重点描述在E_γ=6.13 MeV能点对NaI(Tl)γ探测器的探测效率的绝对刻度方法;给出了实验结果并对实验误差进行了讨论。The reference radiation field of guasi-monoenergetic 6—7 MeV Υ-rays and relevant characteristics were described, concentrating on the absolute calibration method for NaI(T1) Υ-detector efficiency at E_Υ=6.13 MeV. The experimental results were given and their errors were discussed.
