几何均数是用于反映一组经对数转换后呈对称分布的变量值在数量上的平均水平，在医学研究中常适用于免疫学的指标。
发现酸水解HVP产品氯丙醇污染严重，氯丙醇的典型代表3-氯-1，2-丙二醇（3-MCPD）的几何均数达到6。
Results showed that levels of 3-monochloropropane-1,2-diol (3-MCPD) of HVP products are relatively high with a geometrical mean of 6.
在医学统计中，经常会遇到多个几何均数的显著性检验。然而，在现行有关文献中未曾见报道。为此本文通过具体的医学实例对多个几何均数的显著性检验进行了论述。
In medical statistics, significant test for many geometric means is often used. so, in this article, significant tests for many geometric means are expounded through specific medical examples.
本文以年龄别死亡率几何均数作为年龄别死亡率的一个概括指标，优点是直观简单、易计算、不需要标准人口、不同人口可直接比较，并可反映年龄别死亡率的指数类型。
This paper recommends the use of the geometric mean of the age-specific mortality rates as a summary index of mortality. This index is intuitively simple, easy to calculate, and it ne...
