双语版 TED-Ed 演讲精选 Satellite data revealed the vast extent of these losses and chemical tests confirmed that the cause was unquestionably CFCs. 卫星数据揭露了这些损失的具体程度,而化学测试证实,无疑是 CFC 导致的。 BBC世界头条 CFC 11 was supposed to have been phased out by 2010. CFC 11本应在2010年前就被逐步淘汰。 Vox 观点 Soon after, the world's largest CFC producer began to phase them out. 不久之后,这家全球最大的 CFC 生产商开始逐步淘汰氟氯化碳。 牛津上海版高中英语高二下册 They have switched to other less harmful chemicals, and labelled their cans 'ozone-friendly' or 'no CFCs'. 他们改用其他毒性较小的化学品,并在罐子上贴上了这样的标签:“不破坏臭氧层”或“不含氯氟烃”。 牛津上海版高中英语高二下册 To help save the ozone layer, many manufacturers have stopped producing aerosol cans that use CFCs. 为了挽救臭氧层,很多制造商已停止生产使用氯氟烃的喷雾罐。 VOA Special 2018年5月合集 It is the second most common kind of CFC, short for chlorofluorocarbon. 它是第二种最常见的 CFC,是氯氟烃的简称。 SciShow 合集 But, by their estimates, it’ll still take at least 3 or 4 decades to get back to pre-CFC levels. 但是,根据他们的估计,至少还需要3或40年才能恢复到CFC之前的水平。 TED演讲(音频版) 2019年1月合集 And see, it turns out these CFCs were a problem because they were destroying the ozone layer. 看, 事实证明这些氟氯化碳是一个问题,因为它们正在破坏臭氧层。 TED最新演讲系列-2023 The US and UK, along with Canada, norway, sweden and Finland, lead calls for an international band from cfcs. 美国和英国 以及加拿大 挪威 瑞典和芬兰 带头呼吁建立一个禁止氟氯化碳的国际组织。 科学60秒 听力 2014年8月合集 And even then, the planet would have to orbit a special kind of star, a white dwarf, for the CFCs to show up. 即使如此, 环绕白矮星运行类地行星上的含氯氟烃指数成了科学家们研究的对象。 TED演讲(音频版) 2019年1月合集 It led, ultimately, to the banning of CFC usage in aerosol spray cans in the US and a few other countries in 1978. 它最终导致美国和其他一些国家在 1978 年禁止在气溶胶喷雾罐中使用 CFC。 双语版 TED-Ed 演讲精选 While the ban was a win for the climate, as CFCs are potent greenhouse gases, the alternatives that replaced them — hydrofluorocarbons, or HFCs — are too. 这个禁令对气候十分有利;CFC 是强效温室气体,而取代它们的替代品,氢氟碳化物(HFC)也是。 TED最新演讲系列-2023 Unlike existing alternatives, such as ammonia or methelchloride, cfcs were nonflammable and non toxic, meaning they wouldn't burst into flames or cause deadly gas leaks. 与现有的替代品(如氨或氯甲烷)不同 氯氟烃不易燃 无毒 这意味着它们不会起火或导致致命的气体泄漏。 双语版 TED-Ed 演讲精选 In 1987, representatives signed the Montreal Protocol, requiring the rapid phasing out of CFCs and creating a fund to assist Global South countries in obtaining affordable, non-ozone depleting alternatives. 1987 年,代表们签署了《蒙特利尔议定书》,要求迅速淘汰 CFC,并建立一项基金来援助全球南方国家获得负担得起的、不消耗臭氧的替代品。 经济学人(汇总) That means stopping CFC production, which was in the range of millions of tonnes a year, delivered a climate benefit equivalent to cutting carbon-dioxide emissions by billions of tonnes. 这也就是意味着每年停止产生数百万吨的氟氯化碳给缓解气候变化带来的好处,相当于减排数十亿吨二氧化碳。 TED最新演讲系列-2023 In 1987, representative signed the Montreal Protocol, requiring the rapid phasing out of cfcs and creating a fund to assist global South countries in obtaining affordable, non ozone depleting alternatives. 1987年 美国代表签署了 蒙特利尔议定书 要求迅速淘汰氯氟烃 并设立一个基金 帮助全球南方国家获得负担得起的 不消耗臭氧的替代品。 TED最新演讲系列-2023 In the lower atmosphere, cfcs don't break down or react with other molecules, but Millina and Roland showed than in the stratosphere, they're broken apart by UV light, releasing chlorine atoms. 在低层大气中 氯氟烃不会分解或与其他分子发生反应 但米利纳和罗兰发现 在平流层中 氯氟烃会被紫外线分解 释放出氯原子。 万物简史 A single CFC molecule is about ten thousand times more efficient at exacerbating greenhouse effects than a molecule of carbon dioxide, and carbon dioxide is of course no slouch itself as a greenhouse gas. 一个含氯氟烃分子增加温室效应的本事,要比一个二氧化碳分子强1万倍左右,当然,二氧化碳本身也是加剧温室效应的能手。 长喜英语_大学英语六级考试_读美文记单词 There are other important greenhouse gases too and they cannot be ignored—CFCs for example, may account for 25 percent of global warming in the next century if their production is not scaled back. 还有另外一些重要的温室气体也不能忽略——比如说氟利昂,如果不减少其排放量,在未来的一个世纪全球变暖25%的因素是由其引起的。 |
