摘要MHD Alfven wave oscillation for the interpretation of the twin kilohertz Quasi Periodic Oscillations (kHz QPOs) of X-ray spectra of Low Mass X-Ray Binaries (LMXBs) is proposed, and the upper kHz QPO frequency coincides with the Keplerian frequency. The model concludes that the kHz QPO frequencies inversely depend on the disk radius, and the theoretical relation between the upper frequency (nu(2)) and the lower frequency (nu(1)) is nu(1) similar to nu(2)(2), which is similar to the measured empirical relation. The separation between the twin frequencies decreases (increases) with increasing the kHz QPO frequency if the lower kHz frequency is more (less) than similar to 400 Hz.
