What lies behind this meeting is an increasing awareness around the world of the urgency of reducing global warming（全球变暖）.5. Instability is the tendency in certain systems of quantity associated with energy such as current, to increase indefinitely in the absence of excitation（激励）.6. There is no indication in the paper whether the result obtained applies to all cases.7. Microwave（微波）engineering is the branch of electrical engineering that deals with the transmission, control, detection, and generation of radio waves whose wavelength（波长）is short compared to the physical dimensions （尺寸）of the system.8. The creations of a small coterie（组）of malicious（恶意的）hackers who invent toxic（有毒的）software for the sheer deviltry（恶行）of it, viruses（病毒）are short strings of software code that have three properties.9.

In a pure-capacitance（纯电容）circuit the phase (相位) relationship between current and voltage is different from what it is in pure-resistance and pure-inductance（纯电感）circuits. 11. The satellite program will soon send down to the Earth’s surface from orbit every day a quantity of information equal to all the bits of data in the entire Library of Congress.12. I would like to thank the students who passed through my hands, for it was they who, through the years, helped me to refine my initial efforts from which the contents of this volume have been developed.13. Although they follow the same basic pattern described above, television receivers will be dealt with separately.14. All that is necessary is to apply the same force in turn to a standard of mass (质量) and to an unknown mass and then compare their accelerations (加速度), something that can be done anywhere in the universe with the same results.15. Every element exhibits a unique line spectrum（谱）when a sample（样品）of it is suitably excited（激励）, and its presence in a substance of unknown composition（成分）can be ascertained（确定）by the appearance of its characteristic wavelengths（特性波长）in the spectrum of the substance.Part ⅡTranslate the following sentences into English. (45%)1. 本书既讲了实际的设计方法，同时也讲述了理论问题，而重点放在一般概念上。
