摘　　要：介绍了基于熔点法、辐射法、电阻法、声波法以及摄影法等测试技术的原理和进展,从嵌入式和非嵌入式两类测试方案展开分析了烧蚀后退测试技术发展的特点和不足。当前,烧蚀后退在线测试仍然以嵌入式为主;综合来看,电阻法是实现在线后退测试的最佳方案;非嵌入式方案虽然离飞行测试还有一段距离,但是其在地面试验中作为验证技术已逐渐成熟。更加频繁的星际进入任务必将全方位提升在线后退测试技术。The principle and progress of measurement technology based on melting point method,radiation method,resistance method,acoustic wave method and photography are introduced,the characteristics and shortcomings of the development of ablation recession measurement technology are analyzed from the embedded and non-embedded test schemes.At present,the online test of ablation recession is still mainly embedded solutions.To sum up,the resistance method is the best scheme to realize online recession testing.The non-embedded solutions are still some way from flight test,but they are gradually matured as a verification technology in ground test.More frequent interstellar entry missions will promote online recession test technology to achieve all-round improvement.
