摘要：
The kinetic theory is used to study the evolution of the self-gravitating disk of randomly colliding planetesimals. It is shown that as a result of an almost aperiodic Jeans-type instability of small-amplitude gravity disturbances, the disk is subdivided into numerous dense fragments. These can eventually condense into the planetary sequence with mathematical regularity in the spacing formulated empirically by Titius and Bode.
