现在,当务之急是进行理论创新及实践,而非打着治理雾霾的旗号,用不经济和非理性的手段开发所谓的“页岩气”。谈到爱迪生发明,人们会脱口而出“电灯”。但早在1821年,英国科学家戴维和法拉第就发明了电灯,只因不具商业价值而终居实验室。可电灯巨大的社会和经济价值却吸引着爱迪生走进电灯发明的乐趣中,成功发明了直流电照明系统,使直流电成为美国国家标准,并因此迅速做大市场,也使爱迪生的发明家地位不断被神话,甚至不容挑战。由于当时直流电不能升降压而无
Now, it is imperative to carry out theoretical innovations and practices rather than the name of controlling haze, and to develop so-called “shale gas” by uneconomical and irrational means. When it comes to Edison invention, people will blurt out “light ”. But as early as 1821, British scientists David and Faraday invented the electric light, only because of the commercial value of not living in the laboratory. The enormous social and economic value of electric lamps, which attracted Edison’s delight into the invention of electric lights, led to the successful invention of a direct current lighting system that made direct current (DC) the national standard of the United States and thereby rapidly expanding the market and making Edison’s inventor status continuously Myths, do not even challenge. Because at that time the DC can not boost pressure without
