Onwards-continued-fraction-algorithm
- 提出了一种新的Mie散射算法。针对Mie散射系数计算中直接递推所存在的数据溢出问题, 对散射系数的递推公式进行改进, 以连分式形式进行计算,将两个关键函数分别向前递推, 避免了直接计算时贝塞尔函数值超出计算机最大数据限而造成的数据溢出问题。利用Matlab编程,分别计算了不同粒径参数和不同折射率情况下的散射光强分布,并对两种算法的模拟结果进行了分析比较。结果表明,在两种算法都有效的范围内这两种算法的计算结果完全相 符, 而改进的向前递推连分式算法用一个变量循环叠代就能完成连分式的计算, 展宽

- 提出一种新的计算 MIE 散射系数的算法。该算法使用了改进的后向递推公式，可对 MIE 系数中的消光系数 Kext 和散射系数 K sca 进行精确计算。由于新算法能显著地减少计算循环次数， 因此明显缩短了计算时间。对广泛运用的递推法和连分式法进行了比较详细的讨论。并且把新算 法的计算结果和已有的成果进行了比较。结果表明：(1)计算的循环次数与粒子的复折射率基本没 有关系；(2)连分式得到的结果通常最准确；(3)新算法在尺度系数较大时(>1000)，计算时间仅为 连分式
