In this study, sulfate radical concentration from 4 drip water points (PL1, PL2, SH, JG) in the Shihua cave have been monitored for three years, and those from the drip water point was monitored for two years. Drip discharges show three types of response to surface precipitation variations: rapid response, response with associated time-lag and stable. The results show that:(1) SO(superscript 2- subscript 4) concentration in rapid response drip water increases sharply during rain period and has a exponential relationship with drip rate;(2) in the drip water of lag response, SO(superscript 2- subscript 4) concentration has no significant incrcase during rainfall, but they show a increasing trend during a long-term monitoring;(3) SO(superscript 2- subscript 4) concentration at the stable drip site is low and has no obvious change during wet weason.

Dealcoholization temperature markedly influences the surface area and porosity of the resultant MAO-supports. When the support was pretreated at lower or higher temperature, the corresponding MAO-support shows very low surface area;2.XRD and IR analyses indicate that MAO has reacted with the residual ethanol in the supports, which is an important manner to get MAO fixed on the carrier.
