Traditional Chinese medicine science and health maintenance theories have indicated a close relationship between meridian and acupuncture point. Experiences accumulated over the years, together with the involvement of western medicine sciences, have made a big breakthrough in this area. The fundamental relationship between these two bodily structures, nonetheless, remains to be proved by empirical investigations. The current paper aims at examining the conditional change in bioenergy as a function of time. I will recruit 154 individuals ages 17 to 60 as the subjects. Using the Detector of Channel and Acupuncture Points as the instrument, I try to decide if meridian circulation is subject to time difference. The theories on Ryodoraku by Yoshio Nakatani is chosen as the theoretical base for study. Also, the current research employs the surface resistance measurement method to assess the subjects’ change in bioenergy. This method will be combined with A/D interface, a microcomputer, and an artifical intelligence technology. Accordingly I will be able to automatically calculate, analyze, and judge the conditional change in bioenergy value, which is a reflection of the meridian phenomena. The result of two-way analysis of variance (ANOVA) will identify the correlation between meridian circulation and time for different genders. The change of value likewise suggests the correlations between meridian circulation and time and their joint influence on health. Implications related to health preservation and traditional Chinese medicine will be drawn.
