1.读英文报道，找出上述表达的英文说法，并尝试翻译
Israeli researchers say they have invented a reusable face mask that can kill the coronavirus with heat by drawing power from a mobile phone charger. The new mask has a USB port that connects to a power source such as a standard cellphone charger that heats an inner layer of carbon fibers to 70 degrees Celsius, high enough to kill viruses. Disposable masks, in high demand globally during the health crisis, were not economically or environmentally friendly, said Professor Yair Ein-Eli, who led the research team at Technion University in Haifa. "You have to make it reusable and friendly, and this is our solution," he said. It will likely sell at a $1 premium over the price of a typical disposable face mask, the researchers say.
2.参考译文
以色列研究人员称，他们已经发明了一种可重复使用的口罩，可以使用手机充电器充电加热来杀死新冠病毒。这种新型口罩有一个USB接口，可以连接到电源，比如标准的手机充电器。充电时口罩的内层碳纤维可加热到70摄氏度，足以杀死病毒。该研究小组组长、位于海法的以色列理工学院的亚伊尔·埃因-埃里教授称，在健康危机期间全球需求旺盛的一次性口罩既不经济也不环保。他说："口罩最好可以重复使用，并且环保，而这款口罩就是我们的解决方案。"研究人员称，这种口罩的售价可能比普通的一次性口罩高出1美元(约合人民币7元)。
