一、引言实验动物是科学研究的重要手段,其品质高低直接影响科研成果的成败。为保证实验动物的饲育品质,发展了各种屏障设施。目前,生物洁净室、塑料薄膜隔离器、超净空气层流架都是国际上常用的实验动物屏障设施。由于生物洁净室造价昂贵,我国经 I. INTRODUCTION Experimental animals are an important means of scientific research. Their quality directly affects the success or failure of scientific research. Various barrier facilities have been developed to ensure the quality of experimental animals. At present, biological clean rooms, plastic film separators, and ultra-clean air laminar flow shelves are commonly used international experimental animal barrier facilities. Due to the high cost of biological clean rooms, our country
