It illuminates the approach in detail,gives the communication protocols and presents a novel simple and effective method to perform broken-point continuingly-transferring.

Analyses the principle and realization method of multithread and broken-point continuingly-transferring in client/server.

This paper analyses the principle and implement method of multi-thread downloading and broken-point continuingly-transferring based on HTTP on Internet.

Application of DTx Technology to Coal Mine Communication;

By auto-regulating opening and closing of transmitter during speech or silence periods, discontinuous transmission (DTx) can reduce the interference,in return increases speech quality and saves power wasting, especially this technology is comported with large noise underground coal mine.

What s more, it tells about how interrupt transferring is used in the data collecting system.
