It is of significance to the researches and application of pits in foundation-pit retaining.

Research on the Process of Micro-pits on the Cylinder Surface by CNC Machine Tool;

The Principle of Impacting to Manufacture Micro-Pits and Fixing on Parameter of the Micro-Pits Structure;

Fabrication method of micro-pits is proposed in this paper by using micro-ECM with multiple cylindrical micro-electrodes.

Review of heat transfer enhancement for dimpled surface;

The application shows that the optimization can greatly reduce the dimple magnitude and improve the punching quality.

Structural Feafure and Coal-controlling Effects in Zhangping Xukeng Coal Mine of Fujian;

The corrosion failure of Ni-P alloy plating was mainly caused by pitting and the process can be divided into initial stage of corrosion,propagation stage and penetration stage of pitting.

The result indicates that electrochemical corrosion,pitting,turbulence and erosion corrosion and their interaction are the main causes of the perforating and leaking of the tubes.

Effect of pitting corrosion on flexural performance of RC beams;

Also,the influences of the capillary structure to chloride ion permeability and reinforcement localized corrosion(namely pitting corrosion) are pointed out.

Based on the results of other researchers on the corrosion rate of tensile reinforcement steel, moment resistance deterioration models of reinforced concrete girder bridges due to steel corrosion induced by chloride attack or concrete carbonation are developed with pitting corrosion being considered for chloride attack and average corrosion being considered for concrete carbonation.
