From 4 000 to 1 200 a BP the vegetation of the upper mountain zones (between 1 300 ～ 1 600 m) of the Daiyun Mountain Range was a subtropical mixed conifer-hardwood forest dominated by Cryptomeria, Castanopsis, Quercus, and Tsuga.

在距今4 000～1 200年前期间，戴云山脉上部(海拔1 300～1 600 m)的植被为亚热带针阔叶混交类型，优势种属包括Cryptomeria、Castanopsis、Quercus和Tsuga等。

In this study, Cryptomeria japonica was liquefied in phenol with H2SO4 and HCl as a catalyst. The epoxy resin was synthesized from epichlorohydrin and bisphenol A with the molar ratio of 5/1. Blending resins were prepared by mixing the liquefied Japanese cedar and epoxy resin with weight ratios of 30/100, 50/100 and 70/100, and the triethylene tetramine was added as a cross-linking hardener. The effect of mixing ratios of liquefied Japanese cedar to epoxy resin and amount of hardener added on the reactivity of blending resins and the properties of cured resins were investigated. Furthermore, polysiloxane and rice husk were added as foaming agent and filler, respectively, to the epoxy resin and blending resins. The foaming process, the bubbles shape, the mechanical properties, and the thermal stability of the epoxy foams were investigated.

中文摘要本研究将柳杉(Cryptomeria japonica； Japanese cedar)木材以酚为溶剂，H2SO4及HCl为催化剂进行液化处理，另以莫耳比5/1之环氧氯丙烷与双酚A反应合成环氧树脂，并将液化柳杉与环氧树脂以重量比30/100、50/100及70/100混合制备掺合树脂，并以三乙基四胺(Triethylene tetramine； TETA)为架桥硬化剂，探讨液化柳杉与环氧树脂混合比及硬化剂添加量对其掺合树脂之反应性，及其硬化树脂性质之影响；进一步於环氧树脂与掺合树脂中添加聚矽氧烷为发泡剂，稻壳粉为填料制备发泡体，探讨其发泡体之发泡过程、泡体形态、发泡体机械性质与热稳定性。
