　　Samsung has urged owners of the Galaxy Note 7 to turn off the smartphone while it investigates new reports of the device catching fire.

　　The South Korean firm also said it would stop all sales of the phone.

　　But there are now reports that even those phones that had been replaced were catching fire.

　　电池爆炸 exploding batteries

　　最近几年，智能手机市场竞争激烈。各个制造商都在手机电池方面进行“军备竞赛”(arms race)，追求更小的电池，更长时间的续航能力，以及更短的充电时间。

　　据分析人士称，三星这款手机之所以会发生爆炸，就是因为电池的正负极接触导致短路(negative and positive electrodes coming together have caused short circuits)，手机过热，从而引发手机起火和爆炸。

　　召回 recall

　　三星Note7手机起火爆炸事件之后，公司在全球召回了250万台。其中有75%更换了新的Note7手机或者其他机型( replaced with either a Note 7 or another Samsung handset)。

　　停售 stopping all sales

　　召回并更换后的Note7手机仍然发生了多起起火爆炸事故，三星公司发布声明，全面停售该款手机，并要求用户在调查起火原因期间关闭手机(turn off the smartphone while it investigates new reports of the device catching fire)。

　　Samsung's second recall of its Galaxy Note 7 handsets is an unprecedented disaster for the company and the wider mobile phone sector.

　　There have been huge battery-related recalls before - Nokia had to ask consumers to send back 46 million batteries in 2007 because of overheating fears, but because they were removable it did not mean a well-reviewed flagship had to be scrapped.

　　"Stop using your device, back up your data and switch it off," the Samsung told Note 7 owners the day after it confirmed it had shut down its assembly lines following a spate of fires.
