摘　　要：分形结构法是一种测量蛋白质分子尺寸的新方法,但该方法在实际实践中有许多的不足,如:实验周期过长、计算方法太过复杂、对实验条件和设备要求过高等等;针对这些情况,对分型结构法进行了一些改进,如:简化计算方法、在保证精度的同时简化实验过程、缩短实验周期等等;实验结果表明:改进方法后的实验结果和原来高精度实验方法结果相近,误差较小,达到了预期的目的;这证明改进后的方法能够测量牛奶蛋白质分子尺寸。Fractal structure is a new method for measurement of protein molecular size. However, this method has many deficiencies in actual practice. Such as： experimental period too long, the calculation is too complex, the experimental conditions and equipment requirements are too high, etc. For these conditions, we made some improvements to the fraetal structure method, Such as ： simptifie the calculation method, simplifying the experimental process, shorten the experimental period, etc. Experimental results show that： Improved methods are similar with the original high--precision experimental methods, smaller error, achieve the intended purpose, this conclusion has heenproved that the changed method could measure milk molecule protein size.
