Comparison the in vivo activity of 90％EtOH fraction and compound 21 with estradiol, indicated the 90％EtOH fraction behaved the stronger activity on total mineral content, total density, trabecular mineral content, trabecular density and the anti-twist strength of the proximal tibia in OVX rat than estradiol, but compound 21 displayed the weaker activity on total mineral content, total mineral density, trabecular mineral density, cortical mineral content, cortical mineral density, cortical thickness and the anti-twist strength of the proximal tibia than estradiol.

通过90％乙醇部位及化合物21都与阳性对照药雌二醇的纵向比较后，在大鼠OVX模型中，90％乙醇部位高剂量组在提高全骨的骨矿含量和骨密度、松质骨的骨矿含量和骨密度及骨的抗扭力方面，作用强于阳性对照组雌激素类化合物，化合物21在小鼠OVX模型中，抑制了全骨的骨矿含量、骨密度和全骨断面面积的降低，松质骨骨密度的降低，皮质骨的外膜周长的增长，皮质骨骨矿含量量、皮质骨厚度和皮质骨密度的下降及抗扭力的减弱。

By means of GC, GC-MS, GC-IR, IR, H1-NMR,the reaction products were investigated and the results showed that there are camphene, limoneneN terpinolene, Me a -fenchyl ether, Me -terpinyl ether, Me bornyl ether and Me isobornyl ether containing in the products,and the content of the main product Me a -terpinyl ether is up to 42.5%,the selectivity is 44.7%.

采用GC、GC-IR、GC-MS、IR、H~1-NMR等对反应产物进行定量和定性分析，结果表明：微波辐射下α-蒎烯与甲醇的反应产物含有莰烯、柠檬烯、α-小茴香甲醚、异松油烯、异菠基甲醚、菠基甲醚、α-松油基甲醚等，在较好的工艺条件下，主产物α-松油基甲醚的得率为42.5％，选择性为44.7％。

The method is realized by that polyether ether ketone is added into concentrated sulfuric acid to carry out sulfonation reaction, thereby obtaining sulfonated polyether ether ketone, then the sulfonated polyether ether ketone is dissolved in organic solvent, N, N (1)-Carbonyldiimidazole is added to stir for one to three hours, coupling agent is mixed for stirring the reaction for 1.5 to 4 hours, then inorganic crosslinking agent is mixed to react under the temperature of 50 to 80 DEG C. Proton conductors are mixed to continue getting the mixed solution of the sulfonated polyether ether ketone or the inorganic crosslinking agent or proton conductors under the temperature. Finally the proton exchange membrane for a direct methanol fuel cell is obtained by that the mixed solution of the sulfonated polyether ether ketone or the inorganic crosslinking agent or proton conductors is/are processed through membrane forming, drying and exuviation.

该方法首先将聚醚醚酮加入浓硫酸中进行磺化反应得到磺化聚醚醚酮；然后将磺化聚醚醚酮溶于有机溶剂中，加入N，N′-羰基二咪唑搅拌1～3小时后加入偶联剂搅拌反应1.5～4小时，再加入无机交联剂在50～80℃下反应，然后加入质子导体继续在此温度下反应得到磺化聚醚醚酮/无机交联剂/质子导体的混合溶液；最后将磺化聚醚醚酮/无机交联剂/质子导体的混合物溶液成膜，干燥，脱膜即得到所述的直接甲醇燃料电池用质子交换膜。
