为了准确地找出实验条件中影响指标气体产生的主要因素,利用灰色斜率关联模型,分别计算了温庄煤各指标气体生成量与实验的初始温度、温升速率、干空气流量、煤样质量的斜率关联度。计算结果表明,初始温度是影响指标气体产生的关键因素,煤样质量和干空气流量次之,程序升温速率最小。 In order to find out the main factors affecting the index gas production in the experimental conditions accurately, the gray slope correlation model was used to calculate the gas production amount, the initial temperature, the temperature rise rate, the dry air flow rate, the coal sample quality The slope of relevance. The calculation results show that the initial temperature is the key factor to influence the index gas production, the quality of coal sample and the dry air flow rate are the second, and the program heating rate is the lowest.
