off-ratio firing 偏离比例的燃烧
The laws of the flame position and the temperature in the HPM changing with the equivalence ratio or the firing rate have been gained.
得出了火焰面位置及燃烧温度随当量比和燃烧强度的变化而在多孔介质中移动的规律；
After experimenting for eight days, he discovered that firing powdered graphite with clay would work, and the hardness of the pencil lead could be varied by varying the ratio of graphite to clay.
他做了八天实验，发觉把石墨粉末和黏土一起烧，就可奏效。笔芯的硬度还会依石墨和黏土的比例而改变。
Concentration ratio of fire side to back side is adjustable within the wide range of 1 ~ 4 so as to ensure the realization of optimum rich-lean ratio firing under variable load conditions.
向火侧与背火侧浓度比在1 ~ 4的大范围内可调节，保证了锅炉在变负荷工况下实现最佳浓淡比燃烧。
