摘    要:针对从散射谱反演颗粒尺寸分布测量中,由于衍射近似要求近前向取值而带来的反演噪声问题,提出了一种改进的方法.在Chin-Shifrin(C-S)积分变换反演中,插入一种调节函数使得噪声基本消失,又不至于影响反演谱的分布峰位置.对理想单分散颗粒群的模拟效果说明了该法的可行性.对以线阵CCD为接受器件的实验测量和反演结果显示...

Abstract:To reduce noise in the inversion for diffraction measurement of particle size distribution from scattering spectrum,an improved method was proposed.A regulate function was induced in the Chin-Shrine integral transform that led to the noise disappearing and didn't affect the peak of inversion spectrum.The improved method was tested using linear CCD detector array.The result showed that the method largely improved previous results because of using the regulate function,and it is feasible and effective.The aut...
