今年,世界计量日将结合由联合国大会宣布确定、联合国教科文组织实施的“光和光基技术国际年”开展活动。2015年的世界计量日活动将庆祝光在生活中的核心作用,不论其是作为一种能量源,还是光子技术的基础,抑或是人类惊喜和兴奋的一个源泉。计量在实现光基技术的应用方面发挥着核心作用,例如:新型节能照明的发明,需要新的测量来量化其照明效率和对物体外貌的影响;太阳能光伏技术的投资决策,需要参考有关其能效和寿命的准确数据;用卫星遥感直接测量太阳,对于我们更好地认识太阳辐照度及其对气候变化的影响至关重要。
This year, the World Metrology Day will be conducted in conjunction with the “International Year of Light and Photonics Technology” announced by the UN General Assembly to be established and implemented by UNESCO. The 2015 World Metrology Day event will celebrate the central role of light in our lives, whether as a source of energy, as a basis for photonics technology, or as a source of human surprise and excitement. Measurement plays a central role in the application of light-based technologies. For example, the invention of new energy-efficient lighting requires new measures to quantify the lighting efficiency and the impact on the appearance of the object. The investment decision of solar photovoltaic technology requires reference to its energy efficiency And accurate data on life expectancy; measuring the sun directly with satellite remote sensing is critical to our better understanding of solar irradiance and its impact on climate change.
