The urban expressway overpass entrance is an important node of the urban road system. Traffic jams often happen at entrance. The characteristics of urban expressway entrance and the advantages of the microscopic traffic simulation were combined to analyze capacity of entrance. VISSIM simulation software was used and the validity of the simulation model was verified. The influence of the main road traffic flow and the desired speed of entrance to flow and speed of the urban expressway entrance were analyzed through simulation experiment. On the whole, traffic capacity of urban expressway entrance reduces with the increase of traffic flow on the main road. The higher the desired speed is, the faster traffic capacity reduces. The increase of speed and control of main road traffic flow is of great significance for improving the capacity and service level of expressway.

The petroleum ether, acetic ester, methanol and water extracts of laoying tea were prepared and their antioxidant properties were studied. At 160 µg/mL, the methanol extract showed a high reducing power of 1.206. With regard to the scavenging ability on 1,1-diphenyl-2-picrylhydrazyl radicals, extracts were effective in the order: methanol > acetic ester > water > petroleum ether extracts. EC50 values for chelating ability on ferrous ions for petroleum ether, acetic ester, methanol and water extracts were 11.76, 14.32, 6.05 and 1.02 mg/mL, respectively. Based on EC50 values, the various extracts from laoying tea were effective antioxidants.

The influences of extract from Lactarius vellereus fermentation liquid on antioxidant enzymes activity of Alternaria alternata K. were evaluated. Results showed that, in treatment group, the activities of SOD, CAT and POD in mycelia of A. alternata increased at prophase, and SOD activity increased to maximum (31.562 U·g-1) at 5h, while both CAT and POD activity increased to maximum (0.041U·g-1·s-1 and 5.531U·g-1·min-1, respectively) after being administered with 10h. The activities of these three enzymes treated with extract decreased rapidly at anaphase and down to the minimum (0.828 U·g-1, 0.012 U·g-1·s-1, and 0 U·g-1·min-1, respectively) at 40h. While, in control group, SOD, CAT and POD activity always increased with treatment time prolonged.
