At constant viscosity, by increasing the liquid flow rate, the liquid film's velocity is increased; at the same experiment condition, the frequency of the liquid film is same at the same radial direction; the air current has minimum effect on liquid film bottom flow velocity, while it has an obvious effect on liquid film surface flow velocity. The longer the distance between liquid film and the inlet, the lower the pulsatory frequency and longer the wavelength.

Results EROD activities in liver of wild crucian from Zhangtan, Jiangjunyan, Fuyang and Wenyan (23.51±4.17, 16.79±7.39, 18.74±5.16, 18.65±8.86 nmol/) were significantly higher than that of Jiekou (7.84±2.42 nmol/g promin), and no difference was observed between the other sites and Jiekou. Three dose groups (0.25, 0.50, 1.00L/dish water sample extracts) were used in Ames test. Reversional mutation rate of TA98 colony exposed to extracts from Zhangtan was 2.21, 3.39, 6.95 without S9, and 2.70, 4.07, 6.23 with S9, respectively. The revesional mutation of TA100 colony was 2.55, 2.81, 5.36 without S9, and 1.73, 2.86, 4.14 with S9, respectively. Reversional mutation rate of TA98 colony exposed to 1.00L/dish extracts from Jiangjunyan with S9 was 2.22, and there was a dose-response relationship in reversional colony count. Ames tests of the other extracts were negative.
