摘　　要：牛乳脂肪颗粒均匀度因牛个体而异，根据Ｍｉｅ理论中粒子大小对先散射的影响，得出用光散射方法测试的牛乳脂肪必需均质，推导了粒子均匀度与散透比及牛奶脂肪舍量之间的函数关系．并以原奶和均质奶进行对比测试，得出了删试牛乳脂肪的散透比法．Different cows cause the difference of milk fat particle 's uniformity, according to Mie theory of particle size effect on light scattering, we know that the milk must be homogenized, the functional relationships of particle's uniformity to the ratio of scattered intensity to transmitted intensity, the content of fat in milk are derived. From the test of raw milk and homogenized milk, we got a method of the ratio of scattered intensity to transmitted intensity of the test of contenet of fat in milk.
