Rod cells were the most common types of photoreceptor found in all 17 shark species, which means the predators should be able to see within a wide range of light levels.
在17种鲨鱼的视网膜中，最常见的感光体是视杆细胞，这意味着鲨鱼在不同的亮度环境下都可以看得到外界。
Retinas use two main types of light-sensitive cells to allow animals to see: Rod cells help measure brightness, while various types of cone cells help distinguish colors.
动物主要借助网膜中的两类光感细胞获得视觉：视杆细胞帮助感知亮度，而种类众多的视锥细胞则帮助辨别颜色。
In all 17 species, the commonest kind of light receptors were "rod" cells, which are highly sensitive to light and allow night vision but cannot tell colors apart, they found.
在所有17种鲨鱼中，最常见的感光细胞是“杆状”细胞，这种细胞对光线非常敏感，可以使鲨鱼具有夜视能力，但这种细胞无法分辨颜色。
Using the same method, Nathan Scott Hart at the University of Western Australia and colleagues scanned shark retinas for pigments linked with rod and cone cells.
运用相同的方法，西澳大学的纳森·斯科特·哈特和他的同事扫描了鲨鱼的视网膜，以寻找与视杆细胞和视锥细胞相关的色素。
The team took electrical readings from single isolated retinal horizontal cells. They found that light caused a change in electrical current in cone horizontal cells but not in rod horizontal cells.
研究小组对单个视网膜水平细胞进行了电子扫描，发现光引起了锥状细胞中电流的变化，而在柱状细胞中则无此反应。
After two months, the rod was removed and the insulin-producing piglet cells replaced it.
两个月后，将塑料棒取出，代之以能产生胰岛素的小猪细胞。
The long-standing argument centers around outer hair cells, which are rod-shaped cells that respond to sound waves.
这一长期存在的争论的中心是外毛细胞，它是一种响应声波振动的柱状细胞。
Vicia sativa root nodule is usually rod-shaped, it is mainly composed of many cortex cells and a very large central zone which contains meristem, infected tissue and senescent tissue.
箭舌豌豆根瘤为杆形，主要由皮层细胞和一个体积很大，含有分生组织、侵染组织，有时还有衰老组织的中心区域所组成。
A heterotrophic nitrifier, named strain HN, was isolated from the greenhouse soil. The cells of isolates were Gram positive, rod or coccus.
从大棚土壤中分离到一株异养型硝化细菌，命名为菌株HN ，分离菌株为革兰氏染色阳性，球状或杆状。
