烟煤样品胶质层指数值的稳定性研究

Study on the stability of plastic layer index of bituminous coal samples

通过煤样的选取和制备、包装和保存方式等方面对烟煤样品稳定性进行试验,研究了煤样自身稳定性、保存时间和保存方式对不同量值胶质层指数样品稳定性的影响,确定了烟煤胶质层指数样品的最佳保存时间和保存方式,为标准物质的研制提供依据。

The stability of bituminous coal samples was tested from aspects such as selection,preparation,packaging and preservation of coal samples.How the coal sample stability,preservation time and preserving types affected coal samples stability with different plastic layer index values was researched,the best preservation time and preserving method of bituminous coal plastic layer index samplcs were determined.The basis for certified reference material development could be provided as well.
