摘要：
We studied for duplicity the 167 F7-G8 IV or V primaries within 25 pc of the Sun according to their Hipparcos parallaxes and between declinations of -30 degrees and +75 degrees. We obtained an average of 13 coude radial velocities with an accuracy of +/- 0.10 km s(-1). Combining these measures with published data, we obtained 39 single-lined and 12 double-lined binaries with orbital elements. This material will be combined in a later paper with the known visual binaries to derive the secondary mass frequencies.
