• Author introduced following three premises.1. Each vascular bundle and wood parenchyma, which apear on the same cross section of bamboo stem, same properties.2. Number of vascular bundle in same bamboo stem are constant.3. Each spieces of bamboo have constant number and size of vascular bundle respectively.Two theoretical formula were introduced from beforementioned premises and two empirical formula were got from experiments, and then induced mutual formula for physical properties -specific gravity(S) and Shrinkage in volume(λv) 〜 and structural factores 〜 thickness of bamboo stem(H), density of vascular bundl(D) and phloem ratio(B) 〜 were induced.Auther asertained that three premises were right or not, by compare induced formula with empirical formula, and can affirmed that preceding three premises in the right, as table 1.
