汽车检测设备测试数据的准确、可靠和稳定是保证对汽车性能评价客观,保障行车安全的关键。为此,国家有关部门制定了相应的汽车检测设备的检定规程,对检测设备的制造品质和使用的计量技术性能指标进行有效的技术监督和定期的计量检定(周期一般为1年)。笔者在多年来从事汽车检测设备的检定与使用中发现,目前,大多数汽车检测站都 The accuracy, reliability and stability of the test data of the automobile testing equipment are the keys to guarantee the objective evaluation of the car performance and ensure the traffic safety. To this end, the relevant state departments to develop a corresponding test procedures for automotive testing equipment, testing equipment manufacturing quality and the use of measurement technology performance indicators for effective technical supervision and regular measurement verification (cycle is generally 1 year). I have been engaged in the testing and use of the automobile testing equipment for many years. At present, most of the automobile testing stations
