The fluorescence specific properties of alga chlorophyll-a in the sea are analyzed. Therefore theoretical basis is established for the reasonable selection of excitation light source , optical fiber and optical detector.

本文的主要研究内容包括： (1)论述荧光测量法的基本原理及特点，对海藻叶绿素a的荧光特性进行分析，为激发光源、滤光片、光探测器的合理选择及使用奠定理论基础。

The blue-green algae from the source water (Nostoc punctiforme, Phormidium tenue, and an undetermined alga) producing toxin or not was uncertain. It needs further study.

从水源水中分离出的蓝藻(点形念珠藻,小席藻和未定种),对其是否产生毒素还有待进一步研究;从自来水中分离的藻类,没有发现有产生毒素的报道。
