摘要：

We present a detailed and systematic investigation of correlated spectral and timing properties of the Z source GX 349+2, using extensive data (similar to221 ks) obtained from the Proportional-Counter-Array on-board RXTE satellite, during January 1998 and September-October 1998. For the first time a detailed comparison between the normal-branch-properties and the flaring-branch-properties of GX 349+2 has been possible, since this study showed the presence of a rare, extended normal branch. Peaked noise properties have been analyzed as functions of position along the Z-track and have been compared to those of Cyg X-2.
