简介：在数字调查和WSGM优化的结果上的灰色的气体的加权的和的系数(欧洲电脑生产厂商)当模特儿的插值多项式(WSGM)的重要数字(NSF)的数字的效果被调查。调查在一个研磨开火煤的炉子内用这些过程的数字模拟被进行。煤气的阶段的放射的性质用简单灰色的气体被决定模型(SG)，二术语的WSGM(W2)，和三术语的WSGM(W3)。有一样的NSF的欧洲电脑生产厂商的十个集合在W2和W3为每个weighting系数被形成。火焰温度，墙温度，和墙的平均、最大的相对差别价值加热流动被决定。除非它超过了某些价值，调查证明数字调查的结果被NSF影响。NSF的增加必然没导致WSGM优化。NSF(CNSF)的联合是为WSGM优化的必要要求。
