摘要 人红细胞是一种非线性光学介质 ,当入射光的频率ν不同时可获得红细胞的 2ν倍频、ν/2分频、ν/3分频、2ν/3分频散射峰。它在 310 nm、 470 nm、 5 6 0 nm、 6 0 0 nm处产生 4个共振散射峰。人红细胞浓度在 0 .0 5 8× 10 6 个/毫升~ 2 35 .5× 10 6 个 /毫升范围内与共振散射光强度 I6 0 0 nm成正比 。 Human red cell in solution is a nonlinear scattering medium.When the excited frequency (ν) was set to be different frequency,a double frequency scattering and fraction frequency scattering peaks exhibit at the frequences of 2ν,ν/2,ν/3 and 2ν/3.There are four resonance scattering peaks at 310 nm,470 nm,560 nm and 600 nm for the red cell and blood.The concentration of red cell in the range of 0 058×10 6cell/ml^235 5×10 6cell/ml is proportional to the intensity of resonance scattering light at 600 nm,and a novel resonance scattering method for red cell assay has been proposed.
