求翻译：结果显示，空速增大，N2O分解温度升高；O2和N2O浓度在低范围变化，对N2O分解无显著影响；催化活性随着SO2浓度的增加而呈递减趋势，当SO2浓度增大到一定程度后，对催化剂的影响减弱。是什么意思？

The results show that the airspeed increases n2o decomposition temperature; o2 and n2o concentration changes in the low range, no significant effect on N2O decomposition; so2 increase in the concentration of the catalytic activity showed a decreasing trend when so2 concentration was increased to a c

Results show that an empty speed increases, N O 2 decomposition temperature rise; O N 2 and 2 in the low range O concentration changes of N O exploded 2 have no significant effect of catalytic active as SO 2 and presented an increase in the concentration of the trend, when SO2 concentration increase

The result showed that, the airspeed increases, N2O decomposition temperature ascension; O2 and the N2O density in the low scope change, decomposes to N2O not obviously affects; The catalytic activity assumes the degression tendency along with the SO2 density increase, after the SO2 density increase

Results show that airspeed increases, increase in N2O decomposition temperature, O2 and N2O concentration changes in low range, no significant effects on decomposition of N2O; catalytic activity as SO2 concentrations are increasing and a decreasing trend, when the SO2 concentration increases to a ce
