摘　　要：多学科合作开发的数字化自动煤岩分析技术,采用高精度和可改变曝光时间数码摄像头,扩展了灰度级, 提高了反射率测定精度。利用所获高分辩率显微图像,采用图像识别技术,实现煤岩组分的自动识别分类。结合自动扫描、自动聚焦,实现了煤岩特性的自动快速分析。克服了显微光度计速度慢和图像分析仪精度低的不足,继承了显微光度计精度高和图像分析仪的测定速度快的优点,使得测定结果准确、可靠。实现了煤岩特性测定的数字化和自动化,速度快、劳动强度低,操作人员不要经过专业培训。The development of digital automatical analysis technique for the maceral specification is cooperation with the multi - study. The measurement precision of the maceral reflectance is increased due to extended the gray grads with the high precision and the alterable exposure - time digital camera. The maceral recognition was automatically carried out with the high distinguish micro - image and the image recognition technique. The quickly automatically analysis technique for the maceral specification was implemented with the auto - scan and the auto - focus. The techniques, in which the disadvantage for the microscope photometer and the image analysis apparatus was overcame and the advantage for the microscope photometer and the image analysis apparatus was inherited, make the measurement results more credibility and nicety. The analysis techniques that are digital, automation, quick and low labour force for the maceral specification, in which the operator didn＇ t need the specialty training, were implemented.
