Embodiment Construction
[0033] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.
[0034] Here, it needs to be explained that, in order to avoid obscuring the present invention due to unnecessary details, only the processing steps closely related to the solution according to t...

Abstract
The invention provides a model establishing method and a light scattering ingredient detection method. The model establishing method comprises the steps that a fluid medium sample with predetermined concentration and uniform in particulate matter particle size distribution is selected, impurities in the sample is removed, and ultrasonic homogenizing is conducted on the sample under the condition that the particulate matter particle size is greater than a predetermined threshold value to reach micron grade; the sample is put under an optical microscope, and the sample is moved to cut out multiple groups of view images; color adjustment and grayscale adjustment are conducted on the multiple groups of obtained view images; the particulate matter particle size distribution of the sample is obtained by utilizing the multiple groups of obtained view images undergoing the color adjustment and grayscale adjustment; a multi-particle-size distribution particulate matter light scattering property model is established according to the particulate matter particle size distribution of the sample. The model establishing method can fully give consideration to the influence of the multi-particle-size distribution on light scattering of particulate matter in a fluid medium, and a more accurate light scattering detection result can be obtained.
Description
technical field [0001] The invention relates to light scattering detection technology, in particular to a model building method and a light scattering component detection method. Background technique [0002] Particulate matter is dispersed in a gaseous medium or a liquid medium to form two-phase or multi-phase substances, and is a tiny solid, liquid or gas in a divided state. In nature, many substances exist in the state of particles, which constitute one aspect of the colorful tangible world. When light interacts with particles in a fluid medium, optical phenomena such as transmission, scattering, and reflection occur. The inherent properties of the particles, such as the shape and particle size distribution, will affect the propagation of light in the medium. Because the relationship between the particle size distribution of the particles and the scattering of light by the particles is very close, when optical technology is used to detect When the concentration of the s...
