摘要: We compare the results of unified Monte Carlo chemical model with new modified-rate equation (MRE) method under a wide range interstellar conditions, using full gas-grain network. In most explored parameter space, MRE reproduces very well exact approach. Small disagreements between methods may be remedied by use more complete surface chemistry network, appropriate to temperatures employed here.
