摘　　要：安全苛刻系统的可信性需求迫切,支持可信性评估的数据主要来自于测试.为了保证测试数据的可靠性和正确性,特别是对安全苛刻系统这类复杂系统,手工测试实际不可行.研发测试语言是实现自动化测试的有效途径,也是安全苛刻系统自动化测试发展的必然趋势.针对安全苛刻系统通用测试语言应独立于具体设备包括被测安全苛刻系统、测试设备的应用需求,对安全苛刻系统测试中的测试设备协同语句展开研究.针对安全苛刻系统测试中测试设备协同任务中的高阶性、实时性等特点,通过给出测试语言中测试设备协同相关类型、设备协同表达式,定义测试设备协同语句,并通过设备协同表达式求值定义设备协同语句的操作语义规则.最后,对语句的正确性给出相关证明,从而支持安全苛刻系统测试过程中测试设备协同过程的动态性和开放性,支持安全苛刻系统测试语言的通用性.The trustworthiness of safety-critical systems（SCS） is very important. Assessing the trustworthiness mainly depends on data from test. In order to ensure the reliability and validity of test data, especially for such complex systems, manual testing is infeasible in practice. Development of test languages as effective way to implement automatic testing is inevitable trend for automatic testing of SCS. As in general test language for SCS, testing should be independent of specific equipment, including SCS（SCS under test） and test equipment. In the paper, the issues of equipment collaboration are discussed. Aiming at high order and real time characteristics of equipment collaboration during testing, types and expressions of equipment collaboration involved in test of SCS are proposed, and the syntax of statements of equipment collaboration is defined. Then by defining the evaluating rules of these equipment collaboration expressions, semantic rules of statements of equipment collaboration are specified, and related properties are proved to show the soundness of these semantic rules. This work demonstrates that the equipment collaboration is dynamic and open, and the test languages of SCS can be general.
