摘要
对紫外光度法测定水中油类时在标准油品、波长的选择以及氯化钠用量和石油醚纯度等方面存在的问题进行了探讨，提出以工作曲线代替标准曲线，使回收率达到９７％左右。
The expressway landscape and its design and studies,the shift from economic compensation of forestland to landscape compensation during the construction of high grade highway,the measures to conduct ecological environmental protection and the relationship between highway design and living environmental protection are discussed and studied.
