Influence of HgCl_2 on nutrient exchange rates in sediment——water interface in fish cage area of Dapengao;

The study of phosphate exchange rates at the sediment-water interface in fish cage area of Dapengao;

Intact sediment cores which were sampled at 10 sites were incubated on board,and exchange rates were calculated in the function method.

Comments added to the small signal analysis of rate equations of semiconductro lasers;

Taking into account the energy transfer from Yb~(3+) to Er~(3+), the rate equations are given for Er~(3+) ions.

Deriving from the rate equationsmodel of fiberlasers,wegetthe explicitexpressions of outputpowers,slope-efficienciesand thresholdsof fiberlasers.

Attempt to analysis coherently combined fiber lasers by an optical coupler using rate equations;

Study on MacPherson-Srolovitz's grain growth rate equation with Monte Carlo simulation

Numerical analysis is performed for 1319nm and 946nm dual-wave operation condition at the pump-power 10W by using the rate-equation theory and laser putout characteristics curve.

By using both Bessel and Fourier expansion of carrier density,the 2D spatially independent rate-equations for transverse mode are formulated from the spatial-associated rate-equation to spatial-irrelevant one.
