細心的車主朋友都會發現啊，有些汽車的頂部會有一個“鯊魚鰭”模樣的東東，它是干什么的呢？有什么作用呢？今天輪谷就來給朋友們說說這個話題，希望對你有所幫助。
Careful car owners will find that there is a shark fin on the top of some cars. What does it do? What's the effect? Today, Lungu is here to talk about this topic for friends. I hope it can help you.
汽車頂上的“鯊魚鰭”是干啥的？
What's the shark fin on the top of the car for?
車頂的鯊魚鰭，其實就是汽車的天線。
The shark fin on the roof is actually the antenna of the car.
而說到汽車天線，相信你的腦海里出現的是傳統天線，就是那種跟傳統老電視機天線差不多的伸縮式天線，哈哈，此刻你暴露年齡了。
When it comes to the car antenna, I believe what you have in mind is the traditional antenna, that is, the telescopic antenna similar to the traditional old TV antenna. Ha ha, now your age is exposed.
這個鯊魚鰭式天線，其實是來自于一位澳大利亞的飛機維修工程師的發明，他先把飛機上的擾流板移植到汽車上的，還獲得了專權。
This shark fin antenna is actually invented by an Australian aircraft maintenance engineer, who transplanted the spoiler of the aircraft to the car first and obtained the exclusive right.
后來，寶馬公司將其購買，并將接GPS/GSM信號的功能與之相結合，用在了寶馬一系列的車型當中。
Later, BMW bought it and combined it with GPS / GSM signal, which was used in a series of BMW models.
鯊魚鰭天線外觀大方、功能齊全
Shark fin antenna is elegant in appearance and complete in function
結果這鯊魚鰭天線不僅克服了傳統天線的很多缺點，還因為外觀大方、功能齊全并且可以和汽車整體融為一體，讓汽車看上去更時尚、運動。
As a result, the shark fin antenna not only overcomes many shortcomings of the traditional antenna, but also makes the car look more fashionable and sporty because of its elegant appearance and complete functions.
所以深受消費者青睞，因此市場上各種中高 檔汽車紛紛采用了這種鯊魚鰭式天線。
So deeply favored by consumers, so a variety of high-end cars in the market have adopted this shark fin antenna.
有些車頂的鯊魚鰭是后來粘上去的裝飾品
Some of the shark fins on the roof were later glued on decorations
這里我還要特別說明的是，有一些汽車頂上的鯊魚鰭，是后來粘上去的裝飾品。
Here I would like to make a special note that some shark fins on the top of the car were later glued on decorations.
而真 正的鯊魚鰭天線是有接頭的，內置的天線和搭鐵線都是與車身連接的。
The real shark fin antenna has a connector, and the built-in antenna and ground wire are connected with the car body.
鯊魚鰭天線都有哪些作用？
What are the functions of shark fin antenna?
有些朋友可能心里會想：“鯊魚鰭它是天線，可是我現在根本不聽收音機了，那為什么車上還一定要有個鯊魚鰭呢？
Some friends may think: "shark fin is an antenna, but now I don't listen to the radio at all, so why must there be a shark fin in the car?

                         
因為它除了可以接收廣播電臺的信號外，還有一些其它作用的，下面我慢慢說給你。
Because it can receive the signal of radio station, it also has some other functions. I'll tell you later.
1、接收信號
1. Receiving signal
鯊魚鰭天線基本的功能就是天線，它能接收廣播電臺的信號，那我們平時聽收音機的信號就是它接收來的。
The basic function of shark fin antenna is antenna, it can receive the signal of radio station, then we usually listen to the signal of radio is it received.
同時，它也負責接收通訊、網絡的GSM信號，以及定位的GPS信號，為包括導航在內的車載定位、以及各種多媒體功能服務。
At the same time, it is also responsible for receiving GSM signals of communication and network, as well as GPS signals of positioning, providing services for vehicle positioning including navigation and various multimedia functions.
可以說，它集成了包括AM、FM、GPS、GSM等各類信號于一身，能支持普通天線的所有功能，以及其它汽車電子功能。
It can be said that it integrates all kinds of signals including am, FM, GPS, GSM and so on. It can support all functions of ordinary antenna and other automotive electronic functions.
2、釋放靜電
2. Discharge static electricity
鯊魚鰭天線，它其實還是一種對天式靜電放電器。
Shark fin antenna is a kind of electrostatic discharge device.
那根據《山東工業技術》期刊上的論文《汽車鯊魚鰭天線的改良設計》中的說法：
According to the paper "improved design of automobile shark fin antenna" published in the Journal of Shandong Industrial Technology:
鯊魚鰭型汽車天線充分利用電子的特性 , 將靜電電子引導到鯊魚鰭天線的頂端釋放 , 不管鯊魚鰭天線安裝在汽車的什么位置，都可以減少靜電作用。
The shark fin car antenna makes full use of the characteristics of electrons, and guides the electrostatic electrons to the top of the shark fin antenna to release. No matter where the shark fin antenna is installed in the car, the electrostatic effect can be reduced.
具體怎么講呢，就是說在冬季或是非常干燥的秋季時，車身上就容易有靜電，而這些靜電如果不釋放掉，除了輕輕地敲打我們外，還會在加油站帶來非?？膳碌暮蠊?。
Specifically speaking, in winter or very dry autumn, static electricity is easy to appear on the car body. If these static electricity are not released, it will not only knock us gently, but also bring terrible consequences at the gas station.
相信你也看到過，在油罐車的尾部，就有一根鏈條拖在地上，其實它的作用就是釋放靜電，而鯊魚鰭天線就有這個作用。
I believe you have seen that at the end of the tanker, there is a chain dragging on the ground. In fact, its function is to release static electricity, and the shark fin antenna has this function.
把鯊魚鰭天線安裝在汽車的頂部或尾部，可以讓車上的靜電通過它向空中釋放。所以說，鯊魚鰭天線是一種對天式靜電放電器。
The shark fin antenna is installed on the top or tail of the car, so that the static electricity on the car can be released into the air through it. So shark fin antenna is a kind of electrostatic discharge device.
3、擾流作用
3. Disturbing effect
我們都知道的哈，汽車在行駛中會遇到空氣阻力，你開車速度越快，阻力也就越大。
As we all know, a car will encounter air resistance when driving. The faster you drive, the greater the resistance.
如果你汽車上的天線只是單獨存在，而沒有“鯊魚鰭”包裹，就會形成一個小渦流狀的氣流，導致你的風阻加大，噪音也會相應增加。
If the antenna on your car only exists alone and is not wrapped by "shark fin", a small eddy current will be formed, which will increase your wind resistance and noise.
但是，正因為鯊魚鰭有別致的尖 端造型，可以起到切割分流氣流的作用，這樣就免去了渦流氣流的產生，從而降低了風阻，起到省油和降噪的作用。
However, it is precisely because the shark fin has a unique tip shape, which can play the role of cutting and diverting airflow, thus eliminating the generation of eddy current, reducing the wind resistance, and playing the role of fuel saving and noise reduction.
雖然很多汽車會安裝專門的擾流器，但鯊魚鰭也可以起到一定的擾流作用。
Although many cars will be equipped with special spoiler, shark fins can also play a role in disturbing the flow.
4、防追尾作用
4. Anti rear end effect
一些鯊魚鰭上也安裝了LED燈，有些甚至利用了太陽能原理，到了晚上就會交替閃爍，能夠提醒后方車輛的注意。
Some shark fins are also equipped with LED lights, and some even use the principle of solar energy, which will flicker alternately at night to remind the rear vehicles.
特別在遇到極 端天氣，比如霧天或者雨天這樣能見度低的天氣時，能夠起到不錯的效果。
Especially in the face of extreme weather, such as fog or rain, such as low visibility weather, can play a good effect.
總結：鯊魚鰭式天線擁有很具時尚、動感、炫動的外型外。更是集成了FM、GPS、GSM等各種強大汽車電子功能，真 正做到了時尚與功能的完善契合。
Conclusion: shark fin antenna has a very fashionable, dynamic and dazzling appearance. It also integrates various powerful automotive electronic functions such as FM, GPS and GSM, so as to achieve the perfect combination of fashion and function.
