脉搏波系统的力学模型及反演兼对若干中医学问题的讨论

MECHANICS MODELING AND INVERSE ANALYSES OF PULSEWAVES SYSTEM WITH DISCUSSIONS ON SOME CONCEPTS IN THE TRADITIONAL CHINESE MEDICINE

  • 摘要: 对脉搏波进行客观化定量研究,是我们面临的跨中医与西医、跨医学与数理学科的新挑战,是中国传统医学现代化发展的重点研究课题之一.本文遵循中医整体观点的传统思路,把脉搏波系统理解为生命能量以波的形式在血液中传播的整个系统,从连续介质力学的波动理论出发,为脉搏波系统建立一个等价的力学模型,并把力学反演方法推广发展到脉搏波.指出脉搏波是压力波PX,t),质点速度波vX,t)、比容波VX,t)和内能波EX,t)这些不同形式波动的总成.脉搏现象包含着血液的流动和在血液中以远快于血液流速之波速传播的携带能量的脉搏波.前者是人眼易见的实体血液的“物质流”,而后者是人眼不易见、以波的形式传播的“能量流”,可分别理解为中医的“血”和“气”.脉搏波的传播特性由反映生命体整体系统的本构方程决定,就其重要性和地位而言,系统本构方程与中医的体质相当,应探索其内在联系.初步讨论了脉搏波系统本构关系非线性效应和黏性效应对脉搏波特性的影响.

     

    Abstract: The objectification and quantification of pulse diagnosis is one of the important research subjects of traditional Chinese medicine (TCM) modernization. Following the holism concept of TCM, the pulse wave system is considered as an entire system of life energy propagating within the blood in the form of wave, and a corresponding mechanics model is then established. The method of inverse analysis in the wave propagation theory in mechanics is generalized to deal with the pulse wave signals. Once the form of pulse wave, e.g. the pressure wave, is measured, the constitutive equation of the system as well as other forms of pulse wave such as the particle velocity wave, the specific volume wave and the internal energy wave can be deduced. It is indicated that a pulse phenomenon includes both the blood flow and the energy wave propagating within the blood. The former is a visible mass-flow with lower velocity, while the latter is an invisible energy-flow with much higher velocity, regarded respectively to the "blood" and the "Qi" in TCM. The propagating characters of pulse wave are mainly determined by the constitutive equation of the system which may correspond to the "body constitution" in TCM. Some intrinsic relationships may exist between them, and should be further investigated. Moreover, the effects of the non-linearity and the viscosity of the constitutive equation on the pulse wave characters are preliminarily discussed.
