其它杂质则在离心力的作用下被甩出谱片，基本消除了杂质颗粒沉积到谱片上的现象，大大减轻了其对定性铁谱观察和定量铁谱分析的干扰。
Other impurities are thrown out by centrifugal force, which basically eliminates the phenomenon of impurity particles deposited on the spectrum, and greatly reduces the interference of qualitative ferrography observation and quantitative ferrography analysis.
采用双联和磁头快速更换设计，极大的提高了制谱效率和对各种污染油样的耐受力，因此，微电脑双联旋转式铁谱仪特别适用于被严重污染了油液的定性、定量铁谱分析。
With the rapid replacement design of double-link and magnetic head, the spectral efficiency and the tolerance to various contaminated oil samples are greatly improved. Therefore, the micro-computer double-link rotary ferrography instrument is especially suitable for qualitative and quantitative ferrography analysis of seriously contaminated oil.
形成谱片，再利用铁谱显微镜对谱片上的磨屑进行大小、形状、色泽、表面纹理等的观察、磨损类型的识别，磨粒数量的统计，从而得出设备磨损工况的技术。
The size, shape, color, surface texture of the wear debris on the spectrum are observed, the wear type is identified, and the number of wear debris is counted by the ferrographic microscope, so as to obtain the technology of wear condition of the equipment.
