The standard method of asbestos sample analysis by phase-contrast microscopy excludes fibers which are below the resolution limits of the light microscope. Electron microscopic studies revealed that fibers in these small size ranges comprise the majority of fibers in asbestos dust. This research was conducted to determine if the development of a mathematical model for predicting concentrations of small fibers (less than 5 microns length) based on phase-contrast concentrations was feasible. The model presented in this paper was evaluated for its practical utility and was determined to be of minimal value; however, it was felt that the development of a reasonably accurate model can be arrived at through continued research.
通过相差显微镜对石棉样本进行分析的标准方法会排除那些低于光学显微镜分辨率极限的纤维。电子显微镜研究表明，这些小尺寸范围内的纤维在石棉粉尘中的纤维占大多数。开展这项研究是为了确定基于相差显微镜浓度建立一个预测小纤维（长度小于5微米）浓度的数学模型是否可行。本文所提出的模型经过了实际效用评估，结果确定其价值极小；然而，人们认为通过持续研究可以得出一个相当准确的模型。
