解题思路：声呐是利用水中声波对水下目标进行探测、定位和通信的电子设备，是水声学中应用最广泛、最重要的一种装置．

现代轮船利用声呐系统发现冰山，其工作原理是：用它发出超声波，然后用仪器接收障碍物反射回来声波信号，测量出发出信号和接收信号之间时间，根据在水中的声速可以计算出到障碍物距离，从而避免危险．
故答案为：声呐系统．

点评：
本题考点： 声音的综合利用．

考点点评： 本题考查了学生对超声应用--声呐的了解与掌握，属于基础题目，比较简单．

根据公式,F=pgv (p是液体密度,v是排水体积）
F=mg=15000000kg*10N/kg=1.5*10^8N
m/p=15000000/1030=14563.1 m^3
因为从海水进入淡水,密度减小,所以油轮应该沉下
