透光带

颗石球是深海的微藻，典型地繁生于开阔海滨外的透光带内。

Coccophores are pelagic microscopic algae and typically thrive in the offshore photic zone of the open sea .

结果：X线发现术后1,2,4周，FS+MB组与单纯植入MB相比，植骨区周围出现较大的低密度透光带。

RESULTS : On the 1st , 2nd and 4th week , compared with the MB group , a great number of euphotic zones with low density around the bone transplanted zone were found .

生产力的变化对于理解环境变迁有重要的作用，浮游有孔虫和钙质超微生物是海洋中最重要的初级生产者之一，主要生长在上部透光带，是表层海水生产力的主要贡献者。

Variation of growing ability is vital to comprehension of environmental transition . Planktonic foraminifera and calcareous nanofossil are two of the most primary producers , which grow mainly in upper euphotic zones and are main contributors of surface water growing abilities .
