| Abstract: | A set of experimental apparatus on reverse circulation bit are developed, in order to lucubrate the mechanism of the new type reverse circulation bits, and the structure of the bits influencing the ability of taking core and carrying powder. Both the major structure of the equipment and the procession of experiment are described. |
