Menthol and menthyl acetate are both high boiling point matter, A gas chromatographic Model 9790 was used, equippedwith stainless steel column(2m×2mmΦ) packed with SE- 30(5%)and 101 white support.

薄荷醇与乙酸薄荷醇酯都是高沸点化合物。选用9790-气相色谱仪，以5％SE-30/101白色担体作为固定相的不锈钢填充柱为分离柱。

This NS-MCM-41-Pd proves to be an efficient heterogeneous catalyst to catalyze aryl bromides with organozinc reagents for Negishi reaction. In the third suject, fluorescent surfactants with different conjugated aromatic moieties and changeable and gradually extended hydrophobic lengths were successfully synthesized by multiple synthesized manipulations.

It is desirable that a man be clad so simply that he can lay his hands on himself in the dark, and that he live in all respects so compactly and preparedly that, if an enemy take the town, he can, like the old philosopher, walk out the gate empty-handed without anxiety.

一个人若能穿得这样简单，以至在黑暗中都能摸到自己，而且他在各方面都能生活得周密，有备而无恐，那未，即使敌人占领了城市，他也能像古代哲学家一样，空手徒步出城，不用担什么心思。

一个人若能穿得这样简单，以至在黑暗中都能摸到自己，而且他在各方面都能生活得周密，有备而无恐，那末，即使敌人占领了城市，他也能像古代哲学家一样，空手徒步出城，不用担什么心思。

The best catalytic activity and selectivity could be found in the prepared catalyst system with the optimum combination of the ionic liquid, nano-Pd, and support. The stabilizer is also used to prevent the aggregation of nano-Pd particles. One of the advantages of this approach is that the prereduction of catalyst is not required.

其中离子液体、奈米钯金属及担体皆有其功能，三者之组合才能达到良好之效果，同时，在合成奈米钯过程中，必须使用稳定剂以避免奈米钯金属之聚集此触媒系统之另一优点为不需先加氢还原处理，耐水性强且可重覆使用，是一种颇具潜力之选择性氢化触媒。
