Community structure of soil macro-fauna at different restoration stages of an opencast coalmine;

The precautions for athletes\' sports injuries should be provided throughout the athletes\' training stage,competition stage and restoration stage.

The species composition and diversity of moths were studied in the coniferous and broad-leaved mixed forests with Pinus koraiensis at different recovery stages in the Changbai Mountains, Jilin, China, and the associations between the composition of families of moths and forest stands were also analyzed.

Series resonance fault current limiter for recovery voltage after short circuiting of high-voltage circuit breakers at the outlet

In view of the difference between the simulation test circuit consisting of lumped parameters and the distributed parameters in actual system,numerical simulation of the peak values and rising rates of recovery voltage under single-phase earth fault is performed,and the equivalency between simulation test circuit .

The power frequency over-voltage,the secondary arc current,and the recovery voltage of the lines with different tower types and various phase order arrangement are studied under different system operational modes.
