Deviations of the fundamental intervals in equidistant microtonal systems

In contrast to just intonation, not all intervals can be reproduced with sufficient purity using equidistant subdivisions of the octave. Even in the 16th-note system (with 96 notes per octave) the natural seventh is clearly too large. The same applies to the xenharmonic subdivisions of the octave into 17, 19, 31, 43 or 53 tone steps proposed by Ivor Darreg.与纯律（just intonation）不同，通过对八度进行等距细分，无法以足够高的纯净度还原所有音程。 即便在每八度包含96个音的十六分音符系统中，自然七度音程（natural seventh）的音高也明显偏大。 这一结论同样适用于艾弗·达雷格（Ivor Darreg）提出的将八度细分为17、19、31、43或53个音级的异律细分（xenharmonic subdivisions）方案。
