1·There is a heavy attenuation property and there exist sensitive relationships of increase function between attenuation constant and frequency, porosity, osmotic coefficient;
具有强衰减性，衰减系数与频率、孔隙度和渗透系数间存在敏感的增函数关系；
2·Static light scattering can measure the osmotic second virial coefficient of protein solution.
利用静态光散射可以测定蛋白质溶液渗透的第二维里系数；
