用流体静力学称量法测定黄金饰品中金的含量

To Determine the Gold Content of Gold Ornament by Using Fluid Statics Weight Method

本文研究了用流体静力学称量法,通过测定密度、计算金饰品中金的含量.该法简单实用,设备投资少,能满足用户日常检定的需要.该法克服了“试金石”法检定黄金的粗糙性,又解决了电子探针在测试过程中,可能对材料成份偏析所造成的误差.它是电子探针高级测试手段的必要补充.

This paper proposes the fluid statics weight method. It can calculate the gold content of gold ornament by determining the specific gravity. This method is simple and practical, and has less investment in equipment. It can serve the needs of the daily examination and determination. It eliminates the roughness of determining gold by touchstone, and can also avoid the error owing to segregation of material content by using electron probe in the course of determination. It is a necessary supplement to the electron probe.
