汽车顶上鲨鱼的作用是什么？——What is the purpose of shark fins on top of a car

 

汽车顶上的鲨鱼罐的作用是提高汽车的信号和避免静电。

汽车的鲨鱼就是汽汽车上的天线，倘若汽车上安装收音机或车载电话等无线发射设备，在山区路段驾驶时汽汽车上的信号那么就会变得很差，倘若安装鲨鱼罐，车里面的信号接收那么就会提高。

汽车的鲨鱼睛还有静电释放的作用，一旦到冬天或是干燥的秋天，车辆那么就会经常沾上静电，倘若这样的静电不被释放的话，有可能给大家带来麻烦，更会给加油站带来巨大的危险。

The role of the shark tank on top of the car is to improve the signal of the car and avoid static electricity.

The shark is the antenna on the car, if the car is installed with radio or car phone and other wireless transmitting equipment, when driving in mountainous areas, the signal on the car will become very poor, if the shark tank is installed, the signal reception inside the car will be improved.

The shark's eye of the car also has the role of static electricity discharge, once to winter or dry autumn, the vehicle will then often be covered with static electricity, if such static electricity is not released, it may bring trouble to everyone, but also to the gas station will bring great danger.
