柳杉

Various measures have been taken to prevent the spread of the tumor disease of Cryptomeria fortunei on Mount Tianmu, and transfusion of nutrient solution is one of them.

为了防止柳杉瘿瘤病的蔓延对天目山柳杉Cryptomeria fortunei健康的影响，采取了多种防治措施，其中之一就是输营养液。

In the present paper,the floristic characteristics,community structure,population structure,spatial distribution and regeneration pattern of Cryptomeria fortunei were analyzed and discussed at 1 100 m on Mt.

运用系统的群落学调查方法对天目山分布于海拔1100m处的柳杉Cryptomeriafortunei群落进行调查，分析其种类组成和群落结构特征，并对柳杉的种群结构和分布格局进行了探讨。

Besides, the experiment also proves that Cryptomeria japonica essential oil is quite safe for the mice that take high-dose essential oil do not show obvious toxic reaction.

此外，也在实验中发现，小鼠即使服用极高的柳杉精油，也无毒性反应的产生，证实使用柳杉精油有极高的安全性。

Part of the findings shows the composition of pythoncidere is similar to that of the steam-distilled Cryptomeria japonica essential oil, based upon which an experiment about the Cryptomeria japonica essential oil's effect on animals is conducted. This leads to a further finding that the major element of terpene "limonene"is quite effective to central nervous system, and it can be hypnotic, anxiolytic and analgesic.

该研究还发现芬多精的组成与利用水蒸气蒸馏的柳杉精油的成分相类似，於是进一步以柳杉精油进行动物试验，发现了柳杉中的芬多精及其主要的萜类成分－「柠檬烯」，对动物中枢神经系统有相当大的影响，而且具有安眠、抗焦虑及镇痛的功效。

15 Nests were found in the study and about 86. 7% of them were located in the Cryptomeria woodland, 80% of the nesting trees were C. fortunei.

工作期间共发现黄腹角雉巢15个，其中86.7％位于人工柳杉林中，营巢树以柳杉为主，占80％。

The above ground biomassof black locust and cryptomeria stands takes a greater percentage of the totalbiomass than that of water fir and chinese fir stands.

在落叶期，水杉的林冠截留率明显较柳杉林小，而和刺槐林相近，但在盛叶期却明显较刺槐林高，而与柳杉林相近。

According to the data of the analyses,revealed the population of Cryptomeria fortunei exhibited clump distribution pattern,single-dominant community type,sporadic type population structure and is able to natural regenerate...

柳杉种群呈典型的集群分布，并随个体的增大，由集群分布向随机分布发展的趋势，为间歇型的种群结构。通过对天目山柳杉的起源及其更新类型的探讨表明：天目山柳杉林属天然林与人工林共存状态，并可通过幼苗库进行天然更新，但具有机会性和波动性，需林窗和林内倒木等条件。图3表2参25

Based on the results from this study, the essential oils from C. japonica provide a great potential for developing an environmental-friendly chemicals to prevent silverfish to damage living environment.

由本论文之研究结果得知，柳杉精油确具有开发成符合环保要求的居家防虫产品之潜力，未来将可进行剂型的开发以及安全性评估，如此应可赋予柳杉造林木新的利用价值。

The result indicated that both woods of feedstock size of 2×2×10 cm^3 had the highest yields of wood charcoals and vinegars. At the same pyrolytic conditions, the C. japonica had higher heating value of charcoal, yield and soluble tar content of wood vinegar than A. confusa. While, the yield of charcoal, pH value, specific gravity, and organic acid content of wood vinegar of A.

试验结果发现，柳杉及相思树均以2×2×10立方公分者有最高之木炭及木醋液收率；在相同条件下，柳杉之木炭热值、木醋液之收率及溶解焦油含量均高於相思树者，而木炭之收率、木醋液之酸碱值、比重及有机酸含量则均以相思树高於柳杉者。

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。
