计量是测量及其应用的科学,是国家质量基础的核心要素,也是国家治理的技术手段。科学的决策,往往以测量结果为基础。正如世界著名科学家开尔文爵士所说:“测量出真知。(To measure is to konw)”因此,测量结果的准确性、一致性非常重要。而计量作为确保单位制统一和量值准确可靠的活动,是实现测量结果准确性、全球一致的前提。有人形象地说,测量如人类认识和改造世界的一盏明灯,灯的亮度决定着人 Measurement is the science of measurement and its application. It is the core element of the national quality foundation and also the technical means of state governance. Scientific decision-making is often based on measurement results. As the world famous scientist Kelvin said: “To measure is to konw.” Therefore, the accuracy of measurement results, consistency is very important. Measurement as a unitary system to ensure unity and accuracy of the value of the activities, is to achieve the accuracy of measurement results, the global premise. Someone vividly said that measuring the brightness of a lamp as a light that human beings know and transform the world determines
