| The correlation of hydrodynamic conditions (velocity and turbulent dissipation rate)，DTN, DTP, DO, pH to diatom growth were studied by using grey correlation analysis method. The research results showed that hydrodynamic conditions strengthened the correlation between DTN, DTP, pH, DO, and diatom growth. So the hydrodynamic conditions had more indirect effects on diatom growth by changing interaction between the nutrient, dissolved oxygen and pH. In addition, this experiment also obtained the growth models of diatom based on the velocity and turbulence dissipation rate. |
