| 摘 要： | 通过分析激光粒度仪的系数矩阵的计算公式．指出不同焦距下的各个系数矩阵之间存在着简单的比例关系，即可由一个焦距对应的系数矩阵推得另一个焦距的系数矩阵，从而可减少仪器测量所需的系数矩阵数目。这一关系式已由数值计算及对标准颗粒的实测得到证实。

| Abstract: | Through analysis of the coefficient matrix formula in the laser particle sizer, a simple relational expression between coefficient matrixs,which relate to the focus of the Fourier lens,is derived,so that an arbitrary matrix can be derived from another one.By using this relational expression the number of the coefficient matrix can be obviously reduced. The expression is verified through the numerical caculations and experimental measurements for the standard latex spheres. |
