a new method for seismic denoising is proposed. Experiment of f ield data shows its
effectiveness.

Abstract On the basis of mass balance, the new accurate s
uction coefficient and its simplified calculation formula of reciprocating compr essors
were derived, and verified by an example. It is revealed that the suction coefficient of
reciprocating compressor is strongly influenced by the heat exch ange during the suction
process when the reciprocating compressor operates at gas critical conditions, while it is
influenced by the clerance ratio when the rec iprocating compressor operates at other
conditions. This conclusion has signific ant importance for the structure design of
reciprocating compressors working on critical conditions.
