Third, most magnesium alcoholates are prepared by alcoholysis.The process is based on the exchange of alkoxide groups of a metal alcoholate in the presence of an alcohol other than the alcohol corresponding to the original alkoxide,i.e.on the alcoholysis of a metal alkoxide with a different alcohol. Primary alcoholates can be prepared by this process,such as magnesium di-n-propanolate,magnesium di-n-butanolate,magnesium di-isobutanolate.

该方法适用于较高沸点的伯醇的醇镁化合物，例如正丙醇镁、正丁醇镁、异丁醇镁等，但是用醇解法制备出的叔丁醇镁，其纯度只有80％，这是由于叔丁醇具有较大的空间位阻效应，阻碍了醇交换的进一步进行，并且叔丁醇沸点与甲醇相差不大，使得甲醇难以快速蒸出，只能得到一种混合醇盐产物。

In Taiwan area often have typhoon attracting during summer times. Typhoon brings abundant rainfall and the rainfall concentrates to the river, naturally washes out the main channel and the river high alluvion. When flood retreat, the exposed high alluvion can be widely used. Agriculture, plant and wetland, these places can increase zoology. On the other hand ,they baffle current of water flow. So this research focuses on different arrangement of flexible vegetation.

中文摘要因为台湾地区因气候关系常有台风侵袭，台风来临时带来的充沛雨量集中到河川，自然冲刷出主河道和高滩地，当洪水退去时，裸露的高滩地即可以广泛地被利用，有许多的人为开垦、种植，但是这些植生有增加动植物栖地的益处，另一方面也会产生阻碍水流的害处，所以本篇对於不同布置方式的柔性植生做流场的研究。
