摘要
在显微镜光度计的基础上,研制了用微机控制的煤自动扫描显微镜光度计,具有快速、省时,反射率和显微组分含量准确的特点。测定了8种煤样的平均随机反射率,并与手动旋转载物台测定的平均最大反射率比较,误差在2%以内。
Based on microscope photometer, a computerized reflectance microscope photometer was prepared. It works rapidly and objectively. The average arbitrary reflectance were measured for eight coal samples, the error is within 2% as compared with the results from manual rotation of the microscope stage.
