说明: Mie散射系数也叫米散射的Matlab计算程序。
当球形粒子的尺度与波长可比拟时,发生的散射为米散射。此时必须考虑散射粒子体内电荷的三维分布。此散射情况下,散射粒子应考虑为由许多聚集在一起的复杂分子构成,它们在入射电磁场的作用下,形成振荡的多极子,多极子辐射的电磁波相叠加,就构成散射波。又因为粒子尺度可与波长相比拟,所以入射波的相位在粒子上是不均匀的,造成了各子波在空间和时间上的相位差。在子波组合产生散射波的地方,将出现相位差造成的干涉。这些干涉取决于入射光的波长、粒子的大小、折射率及散射角。当粒子增大时,造成散射强度变化的干涉也增大。因此,散射光强与这些参数的关系,不象瑞利散射那样简单,而用复杂的级数表达,该级数的收□相当缓慢。这个关系首先由德国科学家G.米得出,故称这类散射为米散射。

PLS_DA
PLS-DA法是将定量偏最小二乘法用于判别分析的一种策略,其基本思想是将已知类别样本的浓度阵分别设为0、1(对两类用PLS1方法而言),或-1、0、1(对三类用PLS1方法而言),或01、10(对两类用PLS2方法而言),或001、010、100(对三类用PLS2方法而言),多类问题依次类推,再通过定量PLS方法建立模型。(PLS- DA method is to use quantitative partial least squares discriminant analysis of a kind of strategy, the basic idea is to known categories the concentration of the sample matrix is set to 0, 1 (for two types of PLS1 method), or 1, 0, 1 (for three types of PLS1 method), or 01, 10 (for two types of PLS2 method), or 001, 010, 100 (for three PLS2 method), many questions so on, through quantitative PLS method to establish model.)
