4月22日,随着外推法天线测量标准装置实验室在中国计量科学研究院(以下简称中国计量院)正式启用,我国成为世界上继美国、英国、俄罗斯、韩国之后,第5个拥有高精度天线外推法测量系统的国家,这也使我国微波天线计量水平一跃成为世界一流。由中国计量院与英国国家计量院合作完成的外推法天线测量标准装置,完善和 On April 22, as the Laboratory of Extrapolation Antenna Metering Standard Device officially opened in China Institute of Metrology (hereinafter referred to as China Metrology Institute), China became the world’s fifth after the United States, Britain, Russia and South Korea High-precision antenna extrapolation measurement system of the country, which also makes China’s microwave antenna metrology level became a world-class. By the Chinese Institute of Metrology and the British National Metrology Institute completed the extrapolation antenna measurement standard device, perfect and
