摘　　要：针对小张角双锥厚针孔等效直径和视场直径的检测需求,利用60Co γ辐射源设计了厚针孔关键参数测量实验,获得了与计算较为一致的结果。本文所建立的实验方法为厚针孔设计的可靠性与部分加工参数的准确性提供了高精度的验证途径。In order to measure the effective diameter and the field‐of‐view diameter for a thick pinhole with a little‐angle and double cones ,experiments were designed and car‐ried out on a 60 Co gamma source ,and the experimental result agrees well with the calcu‐lated result .The experimental method presented in the paper can supply a high preci‐sion approach to validating the reliability of design and the precision of manufacture .
