任何测量或试验误差的产生,其原因总是多方面的,这主要决定于观测者的感觉器官、仪器的缺陷、试样或试模的差别等。对于一个具体测量或试验所产生的误差,可能某一方面是主导因素。就光面法解离度测定来说,笔者认为,最主要的系统偏差是测定方法内在弊病所造成的。所以,研究测量方法本身导致系统偏差的原因,探求适宜的平差方法,从而提高解离度测定的精确度,对选矿研究和生产都是很重要的。一、偏差产生的原因光面法测定解离度是在亿万个矿粒所制成的光面上进行的。光面包括矿粒所有空间方位的切面。无论用截线法或颗粒数法测 The reason for any measurement or trial error is always multifactorial, depending on the observer’s sensory organs, instrument defects, specimen or test pattern differences, and so on. For a specific measurement or test the error generated, there may be one aspect is the dominant factor. For the smooth method of dissociation measurement, the author believes that the most important system deviation is caused by the inherent drawbacks of the determination method. Therefore, it is very important for research and production of beneficiation to study the reason why the measurement method itself causes the system deviation, and to explore suitable adjustment methods so as to improve the accuracy of the determination of the dissociation. First, the reasons for the deviation Glossy method to determine the dissociation degree is made of hundreds of millions of mineral particles on the smooth. Glossy includes all the spatial orientation of the ore section. No matter using the cross-cut method or particle number method
