A Chinese ship involved in the hunt for the missing Malaysian plane is said to have detected a "pulse signal" in the southern Indian Ocean. The Australian coordinators of the search said the frequency of the signal, as reported by Chinese state media, was consistent with that of a flight recorder. But they stressed they couldn't say whether there was any connection to Flight MH370, which vanished a month ago. More details from Nick Childs. ________________________________________________ The most intriguing element is the apparent frequency of the signal picked up-37.5 kilohertz. That is consistent with the beacon on the black box. But the contact was, it seemed, only fleeting. The search area is also still vast at 84,000 square miles. 一艘参与搜寻马航失踪客机的中国船舶称在南印度洋探测到了脉冲信号.协同搜寻的澳大利亚方面称,据中国媒体报道,该信号发出的频率与飞行纪录仪信号吻合.但他们强调,目前尚不能确定该信号是由一个月前失联的MH370客机所发出.尼克`蔡尔兹带来更多细节报道. _______________________________________该报道中最值得关注的是这个发射波频率,37.5千赫兹,这与飞机上的黑匣子所发射的频率是一致的.但这个信号过于短暂,而搜索区域仍然阔达8万4千平方英里.
