摘　　要：作者采用含牙列的腭图法，利用计算机和图像处理装置，开发了汉语会牙列的腭图图像分析处理系统，把个人内的数次发音样本进行平均化，并进一步把各个人的样本转换至标准牙列、进行规格化，以求得中国人正常者语音发音（普通话）时牙、腭与舌接触范围的标准模型。In this study the artificial palates made of black vinyl seat covering the palate and occlusal surfaces of maxillary teeth were coated with white alginate powder and inserted into the mouth of the subjects. After pronunciation of the test sounds ,the tongue contact areas on artificial palate were demonstrated by wetting of powder and changing in color from white to black.Thus,photographys of palatograms were taken.After taking 5 palatogram of each sound, the samples were averaged by an imageprocessor,The averaged outline of each subject′s palatogram was converted into a standarized dental arch form, with the gray scale of each image reversed and reduced, and thenadded to every pattern of the same sound produced by all subjects. Thus , palatograms were compiled that showed in different gray levelsbased on the frequency of over lapping. Fromthis compiling, contact areas that were common in more than four out of six subjects wereextracted.
