场(厂)内机动车辆属于特种设备，国家对其实施强制性监督检验，而无损检测技术在确保其安全运行中扮演了重要的角色。综述了在其检验过程中分别采用的各种无损检测技术，包括目视检测、超声波检测、表面检测以及噪声测试、速度测试、转向测试和液压系统测试等，并阐述了采用这些检测技术的目的。

The automobile in factories is one kind of special equipments. Based on national requirements, the automobile in factories is forced to perform supervision inspection. Most of the inspection items are nondestructive examination. The nondestructive testing(NDT) technique plays one of the most important roles for insuring manufacturing quality and transportation safety for the automobiles in factories. Several kinds of NDT technique for the automobiles in factories are introduced. At same time, their purposes are expressed. These NDT technique includes visual inspection, ultrasonic testing, surface testing, noise testing, velocity testing, redirector parameters testing, fluid drive system testing and so on.
