柳杉

Blending resins possess the capability of room temperature curing, and had the gel time significantly shorter than that of epoxy resin. Adjusting the pH value of liquefied Japanese cedar could prolong the gel time and increase the weight retention of the cured resin after dissolve testing.

掺合树脂具备常温胶化性，其胶化时间较环氧树脂大幅缩短，调整液化柳杉之pH値可延长其胶化时间，亦可增加其硬化树脂溶出试验之重量保留率。

The results showed that Japanese cedar, Ma bamboo and Makino bamboo all had a good liquefaction efficiency as liquefied in polyethylene glycol/glycerol co-solvent with H2SO4 as a catalyst. The properties of PU foams made from liquefied woody material were influenced by the formulas of PU resins. Wherein, the PU foams made with a higher ratio of isocyanate would had a more complete crosslinking structure, a better mechanical properties and solvent resistance, and a lower water adsorption.

由试验结果得知，以PEG-400/glycerol为液化药剂，H2SO4为催化剂对柳杉、麻竹及桂竹均有良好之液化效果；液化木质材料所制造PU发泡体之性质受各成分调配比例所影响，其中异氰酸酯比例较高者，其PU树脂中液化木质材料之架桥反应较完全，发泡体机械性能及耐溶剂性较高，吸水性较低。

The 51-yr-old Japanese cedar Cryptomeria japonica (L. f. D. Don plantation forest in Taiping mountain area was selected as the monitoring site for forest thinning experiment.

本研究以太平山区51年生柳杉人工林作为疏伐试验监测样区，探讨不同疏伐度(分为对照组0%、25%、28%、30%、33%、37%、38%及53%疏伐度)对枯落物分解及土壤养分释放的影响。

The result exhibit add flutter better than no flutter, especially MDF on 1k~1.25 kHz and Japanese cedar on 1.6 kHz could get the best scattering coefficients S＝1, even on 5kHz still have the scattering effect.

本研究进一步探讨有、无翼板对扩散板散射效果之影响，分别以三组不同木质材料进行比较，结果显示，有翼板之散射效果比无翼板佳，其中又以MDF 於1k~1.25kHz与柳杉於1.6kHz时有最佳之散射效果S=1，且於最高频5kHz时仍有散射效果产生。

In this study, Japanese cedar, Ma bamboo and Makino bamboo were liquefied in polyethylene glycol/glycerol co-solvent with H2SO4 or HCl as catalyst. The liquefied woody materials were blended with PMDI (4,4'-Diphenylmethane diisocyanate;MDI) to prepare the PU foams. The effects of preparation conditions of PU resin on the properties of PU foams were investigated.

中文摘要本研究将柳杉(Cryptomeria japonica； Japanese cedar)、麻竹(Dendrocalamus latiflorus； Ma bamboo)及桂竹(Phyllostachys makinoi； Makino bamboo)等木质材料以聚乙二醇及丙三醇之混合液为溶剂，H2SO4及HCl为催化剂进行液化处理，并将其液化木质材料与4，4'-二苯甲烷二异氰酸酯反应制造聚胺基甲酸酯发泡体，探讨PU树脂调配条件对PU发泡体性质之影响。

After standard fire exposure test, the bending properties of glulam decreased with the fire exposure time increasing. The values of MOE and MOR decreased respectively from 4.1 GPa to 2.5-3.8 GPa and 48.2 MPa to 27.1-36.6 MPa for China fir glulam, from 5.3 GPa to 3.7-4.6 GPa and 54.8 MPa to 23.0-39.4 MPa for Japanese cedar glulam, from 5.3 GPa to 3.4-4.7 GPa and 51.4 MPa to 21.8-38.6 MPa for Taiwania glulam, from 7.7 GPa to 6.6- 6.9 GPa and 62.7 MPa to 33.2-40.8 MPa for Douglas-fir glulam, from 6.0 GPa to 4.4-5.3 GPa and 58.9 MPa to 26.4-42.1 MPa for Southern pine glulam.

经燃烧试验后，集成材之力学性质上，集成材之抗弯强度会随燃烧时间之增加而降低，其中，杉木集成材之MOE值由4.1 GPa降至2.5 - 3.8 GPa，MOR值由48.2 MPa降至27.1 - 36.6 MPa；柳杉集成材之MOE值由5.3 GPa降至3.7 - 4.6 GPa，MOR值由54.8 MPa降至23.0 - 39.4 MPa；台湾杉集成材之MOE值由5.3 GPa降至3.4 - 4.7 GPa，MOR值由51.4 MPa降至21.8 - 38.6 MPa；花旗松集成材之MOE值由7.7 GPa降至6.6 - 6.9 GPa，MOR值由62.7 MPa降至33.2 - 40.8 MPa；南方松集成材之MOE值由6.0 GPa降至4.4 - 5.3 GPa，MOR值由58.9 MPa降至26.4 - 42.1 MPa。
