　　三、測試原理：

　　利用物質對不同波長的光呈現選擇性吸收現象來進行物質的定性和定量分析。如果被測溶液是透明的，當一束定向入射光I經過溶液時，能檢測到定向透射光IC的光強度；若溶液存在不同程度的渾濁，當定向入射光I經過溶液時，必定會產生光的擴散，從而定向透射光IC的光強減小，因此只要準確測量出定向透射光IC的光強大小，**能定量反映出溶液的透明度。

　　Third,the test principle:

　　The qualitative and quantitative analysis of substances is performed by the selective absorption of substances with different wavelengths of light.If the measured solution is completely transparent,when a beam of directional incident light I passes through the solution,the light intensity of the directional transmitted light IC can be detected;if the solution is turbid to varying degrees,when the directional incident light I passes through the solution,it must be Due to the diffusion of light,the light intensity of the directional transmitted light IC decreases.Therefore,as long as the light intensity of the directional transmitted light IC is accurately measured,the transparency of the solution can be quantitatively reflected.
