本文介绍并应用了一种全新的光电检测法——透光率脉动检测技术.它利用悬浮液中颗粒组成的随机脉动变化特性,分析和检测出悬浮液中颗粒的聚集状态及其变化情况.该检测技术可进行流过式连续在线检测,可记录颗粒聚集状态变化过程的每个细节,得到一个连续和完整的检测结果,从而提供了一种非常有用的研究方法;特别是其有效的检测输出值为脉动信号与透射光强度的比值,它不受仪器透光壁面的粘污和电子元器件老化漂移的影响,仪器不需要进行清洗和标定,极大地简化了使用程序.成为该技术的一个突出优点.该技术的光透射式的特点,即检测仪器与被测定液体不发生直接接触,使得多种复杂水质的颗粒聚集状态变化过程的检测成为可能.这些特点是 In this paper, we introduce and apply a new photodetection method, the transmissivity pulsation detection technique, which uses the random fluctuation characteristics of the particle composition in the suspension to analyze and detect the particle aggregation state and its variation in the suspension. This detection technique provides continuous, in-line flow-through detection, recording every detail of particle aggregation state changes and obtaining a continuous and complete test result, providing a useful method of study; in particular, its effective detection The output value is the ratio of the pulsation signal to the intensity of the transmitted light, which is not affected by the smearing of the light transmitting wall of the instrument and the aging drift of the electronic components, and the instrument does not need to be cleaned and calibrated, which greatly simplifies the use of the program. A prominent advantage of the technology’s light-transmission characteristics, that is, the test equipment and the measured liquid do not make direct contact, making a variety of complex water particle aggregation state changes in the detection process possible. These features are
