在生物学的研究和教学方面,不少时候需要使用油浸镜头来观察标本,特别是在细胞学,组织学和微生物学等方面,这种技术操作几乎是不能缺少的。普通一般放在油浸接物镜和切片之间的折光率与玻璃相近似的是香柏油(当然也有用其他油的)。这种香柏油比较昂贵,比较容易挥发,时间过久即不便使用,因而盛放香柏油的容器需要用双层瓶。同时,油浸 In biological research and teaching, it is often necessary to observe the specimens with immersion lenses, especially in terms of cytology, histology and microbiology. This technique is almost indispensable. Commonly placed on the oil immersion objective lens and the refractive index of the glass is similar to the cedar oil (of course, also useful for other oils). This cedar oil is relatively expensive, more volatile, over time is inconvenient to use, so containers containing cedar oil requires double-layer bottles. At the same time, oil immersion
