The specific refractive index increment of Chitosan 壳聚糖折光指数增量的研究
The relationships between the refractive index increment, SEC response area and weight fraction of the monodisperse species of oligomers are analyzed mathematically. 对齐聚物中各半分散组分的折光指数增量、尺寸排除色谱响应面积与重量分数之间的相互关系作了数学分析。
This paper describes the measurement of Second Virial coefficients ( A2) and spe-cific refractive index increment ( dn/ dc) of low molecular weight heparines by low angle laser light scattering photometer ( LALLS) and laser differential refractometer. 用激光小角光散射仪(LALLS)和激光示差折射仪(KMX-16),分别测定了低分子肝素的第二维利系数(A2)和折光指数浓度增量(dn/dc)。
Ion exchange process results in a refractive index increment at the surface thus forming waveguide on crystal. The ion implantation is an effective method to fabricate optical waveguide. 离子交换可以使样品表面的折射率升高从而形成波导结构。
