摘　　要：介绍了5种测量时延的先进方法。通过对这些方法的深入分析和大量实验，得出了这些方法的最佳测量不确定度。同时还提出了“时延传递标准”的新方案，该方案的测量不确定度可达0．01—0．02ns。Five advanced time delay measuring methods are introduced. Through deep analysis and a lot of experiments, optimum uncertainty of measurement for these methods is obtained. In addition, a new concept of Delay Delivery Standard is presented, in which uncertainty of measurement can be up to 0.01 -0. 02 nanosecond.
