Based on mechanism of removal of nitrogen and phosphorus, main affecting factors including concentration of dissolved oxygen, organic loading, sludge age, NO2--N and NO3--N, fluidity mode and circulation rate on simultaneous removal of nitrogen and phosphorus were discussed from the standpoint of reaction kinetics and process kinetics.

A study was made on the dynamic process of the formation of calcium carbonate scale in circulating cooling water system as well as the effects of scale inhibiters on it, with the scale-inhibiting performance of several organic phosphonate scale inhibitors evaluated.

In this paper, the advances in the research on nutrient dynamic process in the estuarine area are summarized.

The dynamic process of a Q switched double pulse ruby laser with μs time separation is presented.

Study on Dynamics Process of Interaction between Oscillatory Drum and Hot Asphalt Mixtures;

This paper simply introduced the basic characteristics of soil erosion on hillslopes, and summarized the three basic dynamics processes of soil erosion, including the process of runoff generation caused by rainfall, the process of sediment yield on hillslope by overland flow, and the process of runoff concentration and sediment transport on watersheds.

The kinetic process of reactive magnetron sputtering has been studied.

The electrode kinetic process of LiFePO_4 in the charge and discharge process was investigated by EIS method.
