- Results show that with increasing applied voltage and O2 concentration, the HO2 production all increases initially and then decreases. 实验结果表明：随着放电电压和体系中氧气含量的增加而增加的HO2自由基数密度分别出现极大值。
- For 300 MWe electrical load, the optimal O2 concentration is 3.4% at outlet of economizer, and for 225 MWe electrical load, the optimal O2 concentration is 4.6%. 当机组负荷为300 MW时;省煤器出口的最佳氧量为3.;4%25左右; 当机组负荷为225 MW时;省煤器出口的最佳氧量为4
- Because the resulting O2 concentration of 7 Vol% is to close to the required concentration of O2 we have to do this twice times to get an Oxygen level in the range of 2 to 3 %. 因为氧气的体积浓度为7%25，接近燃烧所需要的氧气浓度值，所以必须进行两次这样的操作，使用氧气浓度范围为2-3%25。

- The results showed that both burning rates and burn-off rates of chars in O2/CO2 environment were lower than those in O2/N2 environment with equivalent O2 concentration and same operating conditions. 结果表明，在相同的操作条件下，相同O2浓度的O2/CO2气氛下煤焦的燃烧速率较慢、燃尽率较低，各试样的孔比表面积和比孔容积均较小。
- Rhizospheric CO2 and O2 concentration 根际CO2与O2浓度
- Although subsurface regions in a pristine state often have O2 concentrations approaching saturation, the penetration of small amounts of organic matter into these structures can quickly lead to O2 depletion. 虽然地下区域原来状态时O浓度达到饱和,但少量有机物质的渗透就会导致O2迅速消耗。
