1·As the buoy lifted with the surge, a 40-watt light bulb on top of it, powered by wave energy, lighted up.

当浮标被海浪抬起来后，它顶上一盏40瓦的灯泡，被波浪能量的供电点亮了。

2·The floatage state and Load rule of the buoy is analyzed. The causes are found of the buoy submersing in seawater, the alarm light signal ghosting and the buoy cable breaking off.

分析了浮标在风、流、浪作用下的漂浮状态和受力规律，查明了浮标使用过程中存在被海水淹没、信号灯发出的灯光信号难于被发现、浮标缆断缆等问题的成因。
