本文阐明了电磁兼容认证的重要性。为了规范电子电气产品的电磁兼容性,发达国家和部分发展中国家都制定了电磁兼容标准。我国在加入了WTO的新形势下,企业面临着新的竞争压力。提高产品质量,认真对待电磁兼容技术要求和强制进行电子电气产品的电磁兼容认证,是国内设计生产电子电气产品企业和国家相关组织机构的当务之急。 相似文献

Automotive Shredder Residue (ASR) generation in EU is approximately 2–2.5 million t/y, constituting 10% of total hazardous waste in the EU. Currently, about 75% of ELVs total weight is recycled while the remaining 25% (ASR). Not surprisingly, Europe is the world’s largest vehicle producer as about 30% of the 50 million cars produced globally are manufactured in the EU. Worldwide, ASR is considered an increasingly problematic waste, consisting of a large number of different materials that basically remains unprocessed and directed to landfills. The aim of this study is to provide an overview of the ASR problem and the options for processing this waste in order to minimize the waste directed to landfills. 相似文献

In this paper, printing technologies have been employed to print the resonant circuit and detection circuit for an amplitude modulation system (AM radio), which consists of a printed inductor, capacitor, resistor and diode on plastic foils for using as an AM radio circuit. To test the printed inductor, capacitor, resistor and diode as components of AM radio, we selected 640 KHz, the strongest AM frequency in Sunchon City, Korea and monitored the audio signal by replacing each component by a corresponding printed one. As a result the 640 KHz AM radio signals were detected. 相似文献
