The robotic submarine searching for the wreckage from the missing Malaysian airliner was once again forced to cut short its mission on Wednesday. The Australian agency coordinating the search says an unspecified technical problem forced the Bluefin-21 autonomous underwater vehicle to resurface. It is using sonar to create a three-dimensional image of the floor on the southern Indian Ocean where the Boeing 777 is believed to have crashed. ______________________ 周三,搜寻失联马航飞机残骸的水下机器人不得不再次中断搜寻任务.澳大利亚搜寻协调中心表示,由于不明技术故障,自主式水下航行器蓝鳍金枪鱼-21被迫浮出水面.蓝鳍金枪鱼─21利用声呐系统对疑似波音777坠毁的南印度洋海域进行三维成像.________________________
