This paper reviewed the establishment of original Weng model and accomplished the derivation of generalized Weng model, based on Gamma (r) distribution in the probability statistics.
回顾了原翁氏模型的建立，并基于概率统计学中的伽马分布，完成了广义翁氏模型新的推导。

The fluence distribution must be known for absolute gamma ray measurements in spherical radiation fields.
注量率分布是球面源伽玛射线强度绝对测量的必需参数。

The results show that change trend of SPV with time follows gammadistribution and SPV has a peak value.
