| 摘 要： | 当前的金矿物统计工作大多局限于颗粒数百分比计算，而且常常把粒比简单地等同于重量比，这在理论上的实践上均是错误的。金矿物配分的本质是重量上的配分。根据物质的三维尺度特性，在光片中可以用面积比代替重量比；而在重砂分析中应尽量直接测定金矿物的质量，否则只能用体积比代重量比。

| Abstract: | The current statistics of gold minerals is confined to the calculation of percent of grains, which is a mistake in theory and practice. The distribution of gold minerals is the one of weight in nature. According to the matter's three dimension features, the ratio of weight, instead of ratio of area, is used in the polished section identification. The weight of gold minerals is directly measured as much as possible in panning. Otherwise, only the ratio of volume can be used. |

| Keywords: | statistics of gold minerals ration of weight ratio of area ratio of diameter ratio of grains |
