摘　　要：介绍用激光、负透镜和数显卡尺测量微小孔径的测量原理、测量方法，并用激光和万能工具显微镜对小孔孔径进行了对比测量。文中通过实验确定了用激光和负透镜测量小孔孔径的经验公式并进行了误差分析，实验和计算结果表明，该方法是可靠的，测量精度可达0.2(m。This paper introduces the measurement principle and method of small-hole diameter by laser, minus lens, and digital caliber rule, besides it has carried out the contrastive measurement by laser and universal tool microscope. Through experiments it defines the experience formula of measurement to small-hole diameter by laser and minus lens, and error is analyzed. The experiment and calculation results indicate this method is reliable, the measurement precision attains 0.2(m.
