本文用珠壳模型计算了圆柱形（棒状和盘状）颗粒在稀溶液中的流体力学性质。以前关于长径比p>2的杆的结果[Tirado和Garcia de la Torre，J.Chem.Phys.71，2581（1979）; 73，1993（1980）]现在推广到短圆柱体和圆盘，直到p=0.1。的特性粘度得到的棒和磁盘，并提出了一个圆柱形颗粒的三个旋转弛豫时间的结果。流体动力学性质的形式表示，有一个弱的变化与p，因此是有用的实验值的分析。我们目前的例子，DNA寡核苷酸和烟草花叶病毒的圆柱形颗粒的长度和直径的测定。(C)2003年，美国物理学会。
The hydrodynamic properties of cylindrical (rodlike and discoidal) particles in dilute solution have been computed using the bead-shell model treatment. Previous results [Tirado and Garcia de la Torre, J. Chem. Phys. 71, 2581 (1979); 73, 1993 (1980)] for rods with length-to-diameter ratio p>2 are now extended to short cylinders and disks down to p=0.1. The intrinsic viscosity is obtained for rods and disks, and results are presented for the three rotational relaxation times of a cylindrical particle. The hydrodynamic properties are expressed in forms that have a weak variation with p, and are therefore useful for the analysis of experimental values. We present examples of the determination of the length and diameter of the cylindrical particles, for DNA oligonucleotides and tobacco mosaic virus. (C) 2003 American Institute of Physics.
