摘　　要：作者提出用声学法测试纤维开松度。设计了一个用微弱信号检测法去除干扰噪声的测试系统。通过实验得出在一定的体积、频率下,棉纤维对声波的吸收与纤维的重量成正比。实现了棉纤维开松度的在线测试。In this article, authors put forward that the degree of cotton opening can be tested by an acoustic method, and design a testing system which can remove noise by means of detecting signal from noise. From experiment, authors find out that under different volume and frequency, absorbed quantity of acoustic energy is directly proportional to fibre weight. Therefore, on line testing the degree of cotton opening can be relized.
