[Objective] To study virtual plant modeling based on mutual feedback of function-structure.[Method] With the analysis of the shortcomings of current virtual plant modeling method,the modeling with the idea of function-structure mutual feedback was put forward,and the steps of this modeling were elaborated,including the determination of morphological structure model,biomass production model,biomass allocation model,organ reconstruction model,and the integration method of function model and morphological structure model.[Results] The breakthrough of function-structure mutual feedback based mechanism from the boundaries of physiological ecology model and morphological structure model can solve the difficulty of data transmission between the two models and build an integrated model from the two,which can effectively reflect the incidence relation between plant morphology and function,and more suitable for the growth mechanisms of plants.This modeling approach has significant advantages in the dynamic simulation of plant growth.[Conclusion] The virtual plant modeling based on function-structure mutual feedback provides basis for the simulation of plant growth status in the next stage,and has important significance for the accurate simulation of the dynamic growth process of plant. 展开更多

Acupoints are particular areas on the surface of the body through which the Qi and blood of the Zang-fu organs and meridians flow.Acupoints can respond to stimuli and reflect syndromes.Research on the essential morphology of acupoints has two key focuses:anatomical structure and physiological function.The structure is the material and anatomical basis for the function,while the function is the manifestation of the structure.The two factors not only have profound significance for our understanding of the essence of acupoints,but also have great value for clinical acupuncture and moxibustion practice.Based on the structural and functional characteristics of meridians under different physiological and pathological conditions,this paper illustrates the essence of acupoints and explores the rules and biological basis of the acupoint functions induced by acupuncture and moxibustion. 展开更多
