喷雾激光粒度仪中的Cv值的含义，还有浓度值。

1，查说明书，Cv指体积浓度，根据比尔-朗伯定律求得。具体含义还是得问相关研究人员，一般粒度测量不需要。the volume concentration. This is calculated from the Beer-Lambert law and is expressed as a percentage.
比尔朗伯定律物理意义是当一束平行单色光垂直通过某一均匀非散射的吸光物质时,其吸光度A与吸光物质的浓度c及吸收层厚度b成正比.
个人理解若浓度过高，可能结果准确性受到一定影响，多重散射的影响增大了。

2，浓度值指的是遮光度吧，与被测物的粒径，体积有关。a % measure of the amount of laser light obscured by the spray. When no spray is present the obscuration is 0%. The value increases as the spray concentration
increases.
