Unit1Exercises(1)Translate the following sentences into Chinese.1.As with series resonance, the greater the resistance in the circuit the lower the Q and,accordingly, the flatter and broader the resonance curve of either line current or circuit impedance.对于串联谐振，电路中的电阻愈大Q值就愈低，相应地线路电流或电路阻抗的谐振曲线也就愈平、愈宽。
2. A wire carrying a current looks exactly the same and weighs exactly the same as it does when itis not carrying a current.一根带电的导线其外表与重量都与不带电导线完全一样。
3.Click mouse on the waveform and drag it to change the pulse repetition rate, or directly enter anew value of the period in the provided dialogue box, while keeping the pulse width unchanged.在波形上点击鼠标并拖动来改变脉冲重复频率，或者在提供的对话框中直接输入新的周期值，而保持脉冲宽度不变。
4.Electronics is the science and the technology of the passage of charged particles in a gas, in avacuum, or in a semiconductor. Please note that particle motion confined within a metal only is not considered electronics.电子学是一门有关带电粒子在气体、真空或半导体中运动的科学技术。

Text Diode
A diode is a nonlinear electrical device allowing current to move through it in one direction with far greater ease than in the other and usually acting as a one-way valve for current. The most common kind of diode in modern circuit design is the semiconductor diode, although other diode technologies exist. Semiconductor diodes are symbolized in schematic diagrams such as Fig. 2-1.
Oddly enough, the direction of the diode symbol's “arrowhead”points against the direction of electron flow. This is because the diode symbol was invented by engineers, who predominantly use conventional flow notation in their schematics, showing current as a flow of charge from the positive (+) side of the voltage source to the negative (-). This convention holds true for all semiconductor symbols possessing “arrowheads”. The arrow points in the permitted direction of conventional flow, and against the permitted direction of electron flow.

• Late 1950s: Key IC discoveries. • 1958: First silicon integrated circuit is built by Texas Instrument's Jack Kilby. • 1959: Planar process to distribute transistors on silicon, with passive oxide layers to protect junctions, is developed by Fairchild Semiconductor's Noyce and Moore. A modern version of this process is used today. • 1960's: Small Scale Integration (SSI), up to 20 gates per chip.

1 The transistor is what started the evolution of the modern computer industry in motion.晶体管开启了现代电脑工业的革命2 The storage cell only requires one capacitor and one transistor, whereas a flip-flop connected in an array requires 6 transistors.存储单元仅需要一个电容和晶体管，并而不像触发器整列那样需要6个晶体管3 There has been a never ending series of new op amps released each year since then, and their performance and reliability has improved to the point where present day op amps can be used for analog applications by anybody.从此以后每年都有新系列的运放发布，他们的性能和可靠性得到了提升，如今任何人都能用运放来设计模拟电路。
4 This is capable of very high speed conversion and thus can accommodate high sampling rates, but in its basic form is very power hungry.它具有高速转换能力，从而能适应高速采样速率，但它的基本形式非常耗电。
5 During the “on” period , energy is being stored within the core material of the inductor in the form of flux.在”on”阶段，能量以涌浪形式存储在电感的核芯材料里面6 The design goal of frequency synthesizers is to replace multiple oscillators in a system, and hence reduce board space and cost.频率合成器的设计目标是取代系统中多个振荡器，从而减小板卡面积和成本。
