The 0.200g of lead-zinc sample is weighed then followed by addition of diluent of silica dioxide powder for lowering the content of sulfur in the sample .

称约 0.200g铅锌矿矿样，添加稀释剂二氧化硅粉降低 样品中的硫含量。

In this paper the measuring method of these vibrations and1 / 3 octave weighed analysing results of vibration for the sample machine are presented .

本文阐述了对该振动的测试方法并给出了所 测 样机振动信号的1／3倍频程 加权分析结果。
