摘要
应用直条衍射理论 ,通过对人的发丝线径分布及横截面形状进行实验研究 ,得到发丝线径分布均匀、且发丝横截面具有规则几何形状这一符合实际的结论 .这是用衍射原理测量微小量的一种简单、有效的方法 .
After the experimental research in the diameter distribution of human hair and the shape of the cross section by using the diffraction method, it comes to the conclusion that the diameter of human hair is distributed evenly, and its cross section has regular geometric shape. It is an easy and effective way to measure tiny object by using the method of diffraction.\;
