摘要
介绍了提高煤中挥发分测定的准确度和精确度的主要措施 :使用大型的高温炉以便有较大面积的恒温区 ,使用重量基本相近的坩埚以便使试样受热速度一致 ,使用冷却的坩埚架使每次测定的加热速度保持一致 ,水分和挥发分同步测定消除因水分变化而导致挥发分结果的偏差。
The main measurement to promote accuracy and precision of volatile matter in coal:a big constant temperature area can be achieved by using a large oven;samples can be headed at the same speed by using the similar weight of crucible and cool crucible support,the synchro-determination of moisture and volatile matter can eliminate the deviation of volatile matter caused by moisture.
