EMC专业术语
BASIC CONCEPTS  基本概念
Electromagnetic environment: The totality of electromagnetic phenomena existing at a given location.
电磁环境:存在于给定场所的电磁现象的总和。
Radio environment: The electromagnetic environment in the radio frequency range.
The totality of electromagnetic fields created at a given location by operation, of radio transmitters.
无线电环境:无线电频率范围内的电磁环境。在给定场所内处于工作状态的无线电发射机产生的电磁场总和。
Electromagnetic noise: A time—varying electromagnetic phenomenon apparently not conveying information and which may be superimpod or combined with a wanted signal.
电磁噪声:一种明显不传送信息的时变电磁现象,它可能与有用的信号叠加或组合。
Natural (atmospheric) noi: Electromagnetic noi having its source in natural闰年二月
  (atmospheric) phenomena and not generated by man-made devices.
自然(天电)噪声:来源于自然(天电)现象而非人工装置产生的电磁噪声。
Man- made (equipment) noi: Electromagnetic noise having its source in the man-made devices
人为(设备)噪声:来源于人工装置的电磁噪声。
Radio frequency noise: Electromagnetic noise having components in the radio frequency range。
保护生态无线电频率噪声:具有无线电频率分量的电磁噪声。
Electromagnetic radio noi: The total electromagnetic disturbance complex in which an equipment, subststem, or system may be immersed exclusive of its own electromagnetic contribution.
环境无线电噪声:可浸没任一设备、子系统或系统的全部电磁骚扰的合成,其中不包含
Narrowband radio noi: Radio noise having a spectrum exhibiting one or more sharp peaks, narrow in width compared to the nominal bandwidth of, and far enough apart to be resolved by, the measuring instruments (or the communication receiver to be protected). 
窄带无线电噪声:频谱显示有一个或多个尖峰且宽度比标称带宽窄的无线电噪声,其标称带宽离测量仪器(或已防护的通信接收机)可分辨的带宽足够远.
勉为其难是什么意思
Narrowband radio noise: Radio noise having a spectrum broad in width as compared to the nominal bandwidth of the measuring instrument, and who spectral compo。nents are sufficiently clo together and uniform that the measuring instrument cannot resolve them. 
宽带无线电噪声:频谱宽度比测量仪器标称带宽宽的无线电噪声,其谱分量之间相距足够近而且均匀,以致测量仪器不能分辨它们。
Electromagnetic radiation: The phenomenon by which energy in the form of electro。magnetic waves emanates from a source into space. Energy transferred through space in the form of electromagnetic waves。 (By extension, the term radiation sometimes also covers induction phenomena.)
电磁辐射:能量以电磁波的形式由源发射到空间的现象.能量以电磁波形式在空间传播。(电磁辐射一词的含义有时也可引申,将电磁感应现象也包括在内。)
Electromagnetic disturbance: Any electromagnetic phenomenon that may degrade the performance of a device, equipment, or system, or adversely affect living or inert matter。 (An electromagnetic disturbance may be electromagnetic noise, an unwanted signal, or a change in the propagation medium itlf.)
消防口诀
电磁骚扰:任何可能引起装置、设备或系统性能降低或者对有生命或无生命物质产生损坏作用的电磁现象。
Radio frequency disturbance: An electromagnetic disturbance having components in the radio frequency range。
无线电频率骚扰:具有无线电频率分量的电磁骚扰。
Unwanted signal: undesired signal: A signal that may impair the reception of a
wanted signal。
两性氢氧化物对健康的理解无用信号:可能损害有用信号接收的信号。
Interfering signal: A signal that impairs the reception of a wanted signal。 
干扰信号:损害有用信号接收的信号。
Degradation (of performance): An undesired departure in the operational performance of any device, equipment, or system from its intended performance。 (The term degradation can apply to temporary or permanent failure。)
(性能)降低:装置、设备或系统的工作性能与正常性能的非期望偏离。(术语性能降低可用于临时性或永久性失效。)
Electromagnetic interference (EMI): Degradation of the performance of a device, equipment, or system caud by an electromagnetic disturbance。 
电磁干扰(EMI):电磁骚扰引起的设备、传输通道或系统性能的下降。
Radio frequency interference (RFI): 抱枕英文Degradation of the reception of a wanted signal caused by radio frequency disturbance.
无线电频率干扰(RFI):由无线电骚扰引起的有用信号接收性能的下降.
Digital device information technology equipment (ITE) that fails into the class of unintentional radiators, us digital techniques and generators, and uses timing signals or puls at a rate in excess of 9000 puls per second.
数字装置:一种信息技术设备(ITE),属于采用数字技术和发生器一类的非故意辐射器,并采用速率超过每秒9 000个脉冲的时钟信号或脉冲.
Information technology equipment (ITR): Unintentional radiator equipment designed for one or more of the following purpos:
1。 Receiving data from an external source (such as a data input line or a key。board)
2. Performing some processing functions, of the received data (such as computation, data transformation or recording, filing, sorting, storage, transfer of data)
3。 Providing a data output (either to other equipment or by the reproduction of data or
images) .
