目前有几项常规的方法被用于制造金微粒，但多数都会涉及在液态下使用到溶解的氯金酸（又称金盐）及添加化学品以沉降金原子。
There are several ways to produce gold particles, but most involve dissolving chloroauric acid, also called gold salts, in liquid and adding chemicals to precipitate gold atoms.
所以需要利用离心机产生强大的离心力，才能迫使这些微粒克服扩散产生沉降运动。
Therefore, it is necessary to use the centrifuge to produce a strong centrifugal force, in order to force these particles to overcome the proliferation of the settlement movement.
胶体微粒可很容易地放入悬浮体中，但从悬浮体中沉降的速度慢于粘土颗粒大小的物质。
Colloids are easily put in suspension but settle out of suspension slower than clay-sized material.
