查询词典 changing-over

Spring, she quietly and not changing in hundred-leaf,; summer, she falls to shade, ensue, the sound of Tsing Fung, make people comfortable in her front walk, leisure, brought fresh for a happy time; autumn, when falling leaves in hundred-Dr John tried, over the ground, she spit autumn Frost, a flowering of the core, the subtle delicate fragrance sent to thousands of households, brought the sweet smell of your heart.

春天，她悄悄地换叶，不与百花争春；夏天，她为住房遮荫，招来阵阵清风，让人们在她身前舒适地漫步、休闲，带给人们清爽的欢乐时光；秋天，当百花谢尽，落叶满地的时候，她迎着秋霜，吐蕊扬花，把淡淡清香送进千家万户，带给人们沁人心脾的芬芳。

The degree of hydrogenation of methyl benzoate might be controled by adding the promoters and changing the nano-size of ZnO. For hydrogenation of methyl benzoate to benzaldehyde, the active-structure of a catalyst should be modified to decrease the absorption of benzaldehyde on the surface of it, because benzaldehyde absorbed is hydrogenated easily. Using 30-40％ZnO/γ-Al〓O〓 or Li-30％ZnO/γ-Al〓O〓, a higher selectivity to benzaldehyde is obtained. Hydrogenolysis of methyl benzoate to toluene or benzene is carried out effectively using a catalyst modified. For instance, 45.3％ selectivity to benzene and 100％ conversion of methyl benzoate at 420℃ was obtained over 10％ZnO/MCM-41 with the nano-size particles of ZnO (2.4nm).

也可以通过助催化剂的添加和活性组分的纳米化，并根据苯甲酸甲酯多步加氢反应的特点实行加氢深度的调控：苯甲酸甲酯选择性加氢制苯甲醛中，由于苯甲醛容易进一步加氢，需要对活性结构进行调变，以减弱苯甲醛的吸附，使用30-40％ZnO/γ-Al〓O〓催化剂或Li调变的Li-30％ZnO/γ-Al〓O〓催化剂，可获得较高的苯甲酸甲酯加氢制苯甲醛的活性；采用同样的方式，苯甲酸甲酯选择性氢解为甲苯或苯也获得了较好的结果，如使用ZnO纳米化的10％ZnO/MCM-41催化剂，在420℃，可获得45.3％的苯选择性，苯甲酸甲酯完全转化。
