The results were as follows:Afterthe NH_4Y zeolite was dealuminated with Oxalic acid,the conversion of pinenespeeded up markedly, but the selectivity of camphene also dropped downmarkedly.After the NH_4Y zeolite was infused in solution of Mg(NO_3)_2,Zn(NO_3)_2 or Al(NO_3)_3 to remove corresponding oxide,the conversion rate of pinenedropped down,and the selectivity of camphene had little increase.

结果表明：NH_4Y型沸石分子筛经草酸脱铝后，蒎烯转化显著加快，但莰烯的选择性也显著下降；而NH_4Y型沸石分子筛经硝酸镁、硝酸(来源：caAB3aC论文网www.abclunwen.com)锌、硝酸铝溶液浸渍来负载相应的氧化物后，蒎烯转化率有所下降，莰烯选择性稍有增加。

采用GC、GC-IR、GC-MS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-蒎烯与甲酸的反应产物含有三环烯、莰烯、对-伞花烃、α-松油烯、γ-松油烯、柠檬烯、异松油烯、甲酸葑醇酯、甲酸异龙脑酯、甲酸龙脑酯、甲酸芳樟酯、甲酸松油酯。

Camphorate, in which the corn powder was best, while the yam powder and lactic acid were comparatively poorer. The utilization of nitrogen sources by A. camphorate was diverse. The organic nitrogen sources were better than inorganic ones. The best result was achieved when (NH4)2SO4 and wheat bran was co-added, but (NH4)2CO3 could be hardly used when added solely.

樟芝对碳源利用较广，其中以玉米粉效果最好，而对山芋粉和乳糖的利用较差；樟芝对氮源的利用具有差异性，其中对有机氮源的利用较无机氮源好，以硫酸铵＋麸皮复合培养效果最佳，而对碳酸铵几乎不利用。

Seeds were sprouted at 25 ℃.The root-tip with 0.5~1.0 cm length were cut and treated in 4 ℃ refrigerator for 24 hours, fixed for 1~1.5 hours with Carnoy's fixative, differentiated for 10-15 min with hydrochloric acid and Ethanol 95 %(1:1), pressed to section in carmine for staining. Them were observed under microscope, then the samples that differentiated well chosen, covered on frozen station with mountin Canada balsam, for micro-photographing, counting and measuring.
