【摘要】：目的:探讨四种脉象与体质类型存在着的某种规律及小波变换对脉象图分析的可行性。方法:1.选择200名健康研究生,调查方式是根据体质类型的分类标准,包括总体特征、形体特征、常见表现、心理特征、发病倾向及对外界环境适应能力六个方面进行询问;在整个过程中仔细观察体会脉象并做好记录。2.通过查阅文献,找出沉脉、迟脉、促脉、细脉四种较典型的脉象图;借助MatLab工具,采用默认阈值法,对原始脉象图进行消除噪声处理,并采用db4正交小波函数对脉象信号进行四个不同尺度的小波分解。结果:1.男性和女性在各种体质类型中的构成是有差异的(P0.05);2.四种脉象下各个类型体质的分布情况是有差异的(P0.05);3.沉脉多见于阳虚质和气虚质;迟脉常见于阳虚质和湿热质;促脉多见于瘀血质和湿热质;细脉多见于阴虚质、气虚质以及痰湿质。结论:脉象与体质之间存在着某种规律,辨别体质的类型需要四诊合参,掌握总体特征、形体特征、常见表现、心理特征、发病倾向及对外界环境适应能力等进行综合判断;小波变换是处理脉象图的有效方法。
[Abstract]:Objective: to explore the regularity of four pulse patterns and physical types and the feasibility of wavelet transform in pulse image analysis. Methods: 1. According to the classification criteria of physique types, 200 healthy graduate students were investigated in terms of general characteristics, physical characteristics, common manifestations, psychological characteristics, morbidity tendency and adaptability to the outside environment. During the whole process, observe the pulse carefully and make a good record. 2. By consulting the literature, we find out four more typical pulse patterns: Shen pulse, late vein, promoting vein and veinlet. With the help of MatLab tool, the original pulse image is eliminated by using the default threshold method, and the db4 orthogonal wavelet function is used to decompose the pulse signal with four different scales. Results: 1. The composition of male and female in various types of constitution is different (P0.05); 2. Under the four pulse conditions, the distribution of each type of constitution is different (P0.05); 3. Blood vessels were more common in yang deficiency and qi deficiency; late pulse in yang deficiency and dampness heat; blood stasis, qi deficiency and phlegm and dampness were common in blood stasis and dampness heat; blood vessels were more common in yin deficiency, qi deficiency and phlegm and dampness. Conclusion: there is a certain rule between pulse and physique. To distinguish the type of physique, it is necessary to comprehensively judge the general characteristics, physical characteristics, common manifestations, psychological characteristics, tendency to attack and ability to adapt to the external environment. Wavelet transform is an effective method to deal with pulse image.
