为什么手机来电瞬间,附近的车载收音机会出现杂音?为什么在飞机的起飞和降落阶段,空乘会要求旅客关闭所有随身携带的电子设备?要说清这些问题,必须要从一个一般人比较陌生的领域——电磁兼容性谈起。20世纪初,人们通过电台广播信号中的杂音发现了电磁干扰现象。科技发展至今,随着电子电气设备的广泛应用,电磁兼容性已经作为一个研究解决电磁污染的新学科,引起专业领域研究人员和普通民众的关注。
Why is there any noise in the car radio near the cell phone instantaneously? Why is the flight attendant asking the passengers to turn off all the portable electronic devices during the take-off and landing phases of the aircraft? To clarify these issues, we must start from a field unfamiliar to ordinary people - - Electromagnetic compatibility talk about. At the beginning of the 20th century, people found the phenomenon of electromagnetic interference through the noise in radio signals of radio stations. With the development of science and technology, with the widespread application of electronic and electrical equipment, electromagnetic compatibility has been a new subject that studies and solves the problem of electromagnetic pollution, attracting the attention of researchers and ordinary people in the field of specialization.
