摘要

作为高级的运动形态——生命运动，也普遍地包藏着无机界的低级的物理运动形态。研究这种运动形态的学科——生物物理学的某些领域（例如生物力学、生物电学、生物声学等）和生物光学的部分领域（如光合作用、视觉过程）已为人们所熟知。然而生物体普遍存在的微弱和超弱发光的现象，由于弱信号测量技术的限制，研究工作近一、二十年才开展。据报导，生物体内发光大致上可分为三大类

[1]

：机能性的发光、暗发光及诱发发光。机能性的发光如萤火虫发光、细菌发光、水母发光等，有专门的发光器官，这种光用肉眼可见。暗发光（自发的生物发光）和理化因子诱发的生物体发光，属于低水平的生物发光，或称超弱生物发光，不能为肉眼所觉察，只能籍助于具有高灵敏度的光电倍增管的仪器——光子计数器才能识别。

Abstract

There are three types of BL: functional

dark and inductive BL. Three types of BL were measured by LSC operating in-coincidence summation mode. The results indicate that LSC can be employed to measure all BL — not only weak luminescence but also ultra weak luminescence. LSC for measuring BL has some characters

namely high sensitivety

good reproducity and quickness. At present

as commercial photocounter is not available

LSC is a useful tool for measuring BL. In this study

we also make some suggestions on improving LSC for measuring BL.
