摘 要：<正> A method which is especially suitable for microcomputer calculation of the true orientation distribution function（ODF） according to the maximum-entropy estimate is proposed for hexagonal system polycrystalline materialswith physical symmetry.The resultant computational software system has been also designed and first carried outin a microcomputer PANAFACOM-U1200 being on line with the X-ray diffractometer D/max-3A.The simu-lated calculation shows that the method is concisely pragmatic and easily popularized,while the results obtainedare trust worthy.
