摘要：本文提出一种用于水污染生物检测的恒流稀释装置,介绍装置的运转原理、结构及其评价。本装置的浓度变异系数在3.05—11.76%之间,与国外同类产品接近,由于结构简单,运转可靠,不需电力,本装置可广泛用于水生生物毒性试验,特别适于长期的亚致死和慢性毒性试验。

Abstract：A constant-flow dilution apparatus for single or mixed pollutants has been developed. The variation coefficients of concentration ranged from 3.5% to 11.76% which were comparable with other similiar apparatus. Because of the simplicity of construction, reliability of opperation, no need of electricity and a wide variety of uses, the apparatus is applicable to toxicity testing, especially long-term sublethal or chronic testing with aquatic organisms.
