假设混合气体爆炸下限气体为1.2%，分子量为100g/mol，风量为100000NCMH，标态浓度计算：1.2%*100000/22.4*100/100000=53.4mg/m3，这个数据明显不符合实际，一般RTO系统中，浓度可以做到10g/m3，仍处于安全范围内。

NCMH是什么单位？一般风量不是标方Nm3/h吗？ 10g/m3折算成体积百分比是0.224%，这个浓度还没有到达爆炸下限范围，另外安全的范围并不是说爆炸极限范围内就出安全事故，安全事故的三要素同时满足才可会出问题。一般我们认为爆炸下限的25%是安全的

你的单位错了，计算出来的结果应该是53.4g/m3

他计算式是什么意思？还给加5财富？
