本文提出了用量子（群子）统计力学参数（R1,R2）界定中药阴阳性的两种方法:根据生命动力元素重度进行统计和根据生命动力元素含水离子亲电强度进行统计。结果显示第二种方法更适于描述中药的性味和阴阳性:群子参数R1较小且亲电强度分布低的中药属于阳性,且大多数以甘、辛、淡、温为主;群子参数R1较大且亲电强度分布高的中药属于阴性,此时大多数以苦、酸、涩、寒、凉为主。同时还发现以具有最高磁矩的铁离子为中心磁矩,向两侧越来越变小,当以Ti、V、Cr、Mn、Mo、Zn等低磁矩元素分布为主时,该中药药性属阳,而以Fe、Co、Ni、Cu等低磁矩元素分布为主的中药则药性属阴。本文的主要贡献在于用量子（群子）统计力学的方法来定量地研究中药的药性阴阳,这是一种能够使西方医学界可接收和理解的阴阳属性。

In this article are put forward two methods for bounding the yin and yang attributes of Chinese medicines by the parameters (R1 and R2) of quantum (Sub - cluster) statistic mechanics, i. e., statistics based on the multiplicity of vital power elements and on the electrophilic strength of aquo ions of vital power elements respectively. The result shows that the later is more suitable to describe the property and yin - yang attribute of Chinese medicines: Chinese medicines with lower parameter R1 of sub - clusters and weak distribution of electrophilic strength are of yang, which mostly taste sweet, pungent, light and mild and those with higher parameter R2 of sub - clusters and strong distribution of electrophilic strength are of yin, whose taste are mainly bitter, sour, puckery, cold and cool. It appears that the strongest magnetic moment of Fe ions, if taken as the centre, becomes more and more weak towards the two sides of the centre. The Chinese medicines, which are mainly composed of elements with weak magnetic moment, such as Ti, V, Cr, Mn, Mo and Zn, are of yang while those which principally consist of such elements with weak magnetic moment as Fe, Co, Ni and Cu are of yin. The primary contribution of this article is that the yin and yang attributes of Chinese medicines are quantitatively studied by the way of quantum (sub - cluster) statistic mechanics, such yin and yang attributes that can be accepted and understood by the Western medical circles.
