可以幫我翻譯這篇電子學簡介?

~INTRODUCTION~

The transistor was invented by a team of three men at Bell Laboratories in 1947. Although this first transistor was not a bipolar junction device , it was the beginning of a technological revolution that is still continuing . All of the complex electronic devices and systems today are an outgrowth of early developments in semiconductor transistors .

Two basic types of transistors are the bipolar junction tarnsistor (BJT), which we will begin to study in this chapter , and the field- effect transistor(FET), which we will cover in later chapters . The BJT is used in two broad areas- as a linear amplifier to boost or amplify an electrical signal and as an electronic switch . Both of these applications are introduced in this chapter .

~INTRODUCTION~簡　介The transistor was invented by a team of three men at Bell Laboratories in 1947. Although this first transistor was not a bipolar junction device, it was the beginning of a technological revolution that is still continuing. All of the complex electronic devices and systems today are an outgrowth of early developments in semiconductor transistors.電晶體是貝爾實驗室的一個三人小組於1947年所發明。雖然第一個電晶體並非雙極性接面裝置，但那是一個技術革命的開端，直到現在還持續進行。目前，所有複雜的電子裝置與系統，都是早期半導體電晶體一路發展的成果。Two basic types of transistors are the bipolar junction tarnsistor (BJT), which we will begin to study in this chapter, and the field-effect transistor (FET), which we will cover in later chapters. The BJT is used in two broad areas - as a linear amplifier to boost or amplify an electrical signal and as an electronic switch. Both of these applications are introduced in this chapter. 電晶體的兩種基本類型，一是雙極接面電晶體(BJT)，我們將在本章中開始學習；另一則為場效電晶體(FET )，我們將在以後章節中論及。雙極接面電晶體用在兩個主要範圍：作為線性放大器(對電的訊號進行增幅或放大)，以及作為電子開關。這兩種應用，在本章中都會介紹。

介紹1947 年晶體管由三個人的隊發明了在響鈴實驗室。雖然這支第一支晶體管不是一個雙極連接點設備, 這是仍然繼續一次技術革命的起點。所有複雜電子設備和系統今天是早期的發展分枝在半導體晶體管裡。二基本的類型晶體管是雙極連接點tarnsistor (BJT), 我們將開始學習在這個章節裡, 並且領域作用transistor(FET), 我們將包括在最新章節。BJT 使用在二個寬廣的區域作為一個線性放大器促進或放大一個電子信號和作為一個電子開關。這兩種應用被介紹在這個章節裡。
