To improve the pollutant removal efficiency by non‐thermal plasma(NTP),the effect of H2O vapor and O_(2)on removal efficiency of NO and SO_(2)as well as the reduction of CO was investigated in H_(2)O/O_(2)/SO_(2)/NO/C_(3)H_(6)/CO_(2)/N_(2)*** analyse the reaction mechanism,the effects of H2O vapor and O2 on the emission intensity of Oð3p^(5)P→3s^(5)S0_(2)Þand OHðA^(2)Σþ→X^(2)ΠÞwere *** experimental results show that the increase of H_(2)O vapour(0%-9.8%)promotes the generation of OH radicals,increases the removal efficiency of NO from 18.9%to 57.3%,decreases the energy per NO removed from 449.0 to 148.1 eV/NO,increases SO_(2)removal efficiency from 4.8%to 35.3%,decreases the energy per SO_(2)removed decreases from 2784.0 to 582.9 eV/SO_(2),and reduces the generation of CO from 460 to 229 *** the range of 0%-15%,the increase of O_(2)content promotes the formation of O radicals,increases the removal efficiency of NO from 8.5%to 54.2%,and decreases the energy per NO removed from 994.3 to 156.4 eV/*** the range of 0%-5%,increasing O_(2)content promotes SO_(2)removal efficiency from 8.7%to 24.8%,and decreases the energy per SO_(2)removed from 2485.7 to 876.6 eV/SO_(2).However,CO generation increases from 200 to 350 ppm with the increase of O_(2)in 0%-5%due to the incomplete oxidation of C_(3)H_(6).In the range of 5%-15%,the increase of O2 produces more O radicals,decreases the removal efficiency of SO_(2)from 24.8%to 23.5%and the generates of CO from 350 to 311 *** study is helpful for improving the efficiency of NTP for desulfurization and denitrification,while reducing the by‐product CO.

挡墙后铺设柔性垫层或回填轻量土,对其优化设计和降低成本有着重要的工程意义。通过开展不同级别荷载下的挡土墙物理模型试验,分析墙后铺设EPS柔性垫层、回填泡沫轻量土及二者同时施加时的墙后土压力大小及分布特征,并探讨相应的减载效应。结果表明:挡土墙铺设柔性垫层、回填轻量土或二者同时施加时,墙后土压力均随埋深呈先增大后减小的“鼓肚”状非线性特征,土压力最大值多出现在1/2墙高处;同等荷载作用下,仅回填轻量土的减载效果相对较弱,减载率为10%~25%,而铺设柔性垫层的最大减载率较之提高了1.5倍,当二者同时施加时,减载效果最佳,最大减载率相应提高了近3倍;柔性垫层减载效果随着厚度的增加逐渐降低,但泡沫掺量对墙后回填轻量土的减载率影响更为敏感。工程中可考虑采用中等厚度的垫层,若墙后填土附加荷载较大,可适当提高回填泡沫轻量土的掺量。
