With determining and comparing the result of the output of chlorine dioxide, the purity of chlorine dioxide, the rate of chlorine dioxide, the capacity of active chlorine and the output of chlorine generated by positive pressure type chlorine dioxide generator under different pressure, this paper draws the conclusion that the effect of pressure to aerogenesis efficiency of chlorine dioxide generator is indistinctive when the pressure is in the range of 0～0.6M Pa.

从化学平衡角度分析，压力增加会抑制正向反应的进行。为了验证实际效果是否如此，本文通过在不同压力下对正压式反应器 ClO2产量、纯度、得率及总有效氯产量等指标进行测定与比较得出，在 0～0.6M Pa的常用压力下，压力的变化对二氧化氯发生器的产气效率无显著影响。

Huangqiao carbon dioxide gas field in North Jiangsu Basin have the following characteristics: deep gas fields are associated with shallow ones, marine gas fields are coupled with continental ones, and several gas reservoirs are combined. Carbon dioxide in Huangqiao area mainly comes from deep mantle, mixed with a little thermal metamorphism and a little organic carbon dioxide in shallow formation, and helium and nitrogen gas mainly come from mantle. There is a good time\|space matching relationship between carbon dioxide gas reservoirs and great rifts, magma and volcano activity, which forms the special carbon dioxide gas reservoir mode for Huangqiao. This mode has good sealing, trapping and preserving conditions, but its gas source differs from traditional hydrocarbon gas reservoirs.
