Since 1960 s, the study of deep-water tractive current deposits has become a new research field in sedimentology.

History,status and prospect of study on deep-water traction current deposits;

Low - density turbidity current is a transition flow evolved from gravity flow to drag flow,whose supporting mechanism and transporting way of the sedimentary grains have different characteristics in the different stages of sedimentary evolution process, so the mineral components, grain sizes, sorting characteristic, depositional textures,etc.

di/dt and ΔI protection of DC traction supply system for metro vehicles;

The application of LOGO! in the DC traction SCADA of urban rail transit

The calculation of short-circuit current in DC traction network offers an important basis for the selection of electrical equipment,the design of protective-relay device and the decision for operation mode of traction substation.

Calculation and simulation analysis of AC traction for metro EMUs;

Load-feedback scheme comparison in bench test of AC traction drive system and traction motor;

AC drive has become the main way in the domain of electric traction,the test rig of AC drive for electric traction is key test equipment to the research,development,validation for converter of the AC drive system,AC traction motor and control system of converter.
