An energy source(a primary or secondary cell, a generator, and the like)convertschemical mechanical,thermal or some other form of energy into electric energy.An energy

converter, also called load(such as a lamp, heating appliance, or electric motor), converts electric energy into light，heat mechanical work，and so on.電源（如原生電池、再生電池和發(fā)電機等）將化學(xué)能、熱能或其他形式的能量轉(zhuǎn)換城電能。能量轉(zhuǎn)換器（也稱作負(fù)載，比如燈泡、取暖器及發(fā)電機等）將電能轉(zhuǎn)換成光、熱和機械等能量

AC.circuit analysis involves the addition of harmonic time functions having the same

frequencies but different peak values and epoch angles.Direct addition of such functions.Would call for unwieldy trigonometric transformations.Simpler approaches are provided bythe Argand diagram(graphical solution)and by the method of complex numbers(analytical solution)

交流電路的分析包括對有相同頻率、不同幅值和初相角的諧振時間函數(shù)的加法。這些函數(shù)的直接相加將要求用到復(fù)雜的三角轉(zhuǎn)換。簡單的方法是采用阿爾岡圖法（圖解法）和復(fù)數(shù)方法（解析方法）

The entire system of Boolean algebra can be built up using combinations of only three

basic functions, the logic AND,the logic OR,and the logic NOT(or negation).Any Boolean equation can be realized by some combination of these three basic functions.These three

bsic functions will be discussed in detail below.布爾代數(shù)的整個系統(tǒng)都可以由三個基本函數(shù)邏輯‘與’‘或‘‘非’組合構(gòu)成。任何一個布爾等式可由這三個基本函數(shù)中的一部分組合而成，以下將詳細(xì)討論這三個基本函數(shù)。Many types of automatic control systems have appeared during the twentieth century，based on electronic mechanical, hydraulic and fluidic principles.In each case the design techniques have been similar because each component of the system usually contributes a single well defined function to the system behaviors

在20世紀(jì)，出現(xiàn)了許多種基于電子、機械、液壓和流體原理的自動控制系統(tǒng)。由于系統(tǒng)中的每一元件通常對系統(tǒng)的運轉(zhuǎn)狀態(tài)只起單一 確定的功能，各種類型系統(tǒng)的設(shè)計技術(shù)是相似的 The first advantage has already been mentioned;the large scale integration of

electronic systems has reduced the number of components which are used, leading to an increasein the overall reliabilityof the system and a reduction in assembly costs.The decreasein size which results from largescale integration means that the equipment based onmicrocomputers is usually much smaller, lighter, and more robust than that using older technologies.第一個優(yōu)點已經(jīng)提到過了，就是電子系統(tǒng)的大規(guī)模集成已經(jīng)降低了所用的元件數(shù)量，促使系統(tǒng)的總體可靠性的提高和裝配費用的降低。由于大規(guī)模集成引起的尺寸減小意味著基于微計算機的設(shè)備功能通常要小得多，輕得多，并且比用舊技術(shù)制成的設(shè)備要更為強大Electronic systems are used forihandling information in the most general sense;This

information may be the telephone conversation, the instrument reading or ‘the company’saccounts, but in each case the same main types of operation are involved;the processing, the storage and the transmission of information.In conventional electronic design,Theseoperations are combined at the function level;for example, a counter, Whether electronicor mechanical, stores the current count and increments it by one as required.A systemsuch as an electronic clock which employs counters has its storage and processing capabilities spread throughout the system because each counter is able to store and process numbers.廣義的說，電子系統(tǒng)是用于處理信息的，這種信息可以是電話交談、儀器讀數(shù)或企業(yè)賬戶，但是各種情況下都涉及相同的主要操作：信息處理、儲存和傳送。在常規(guī)的電子設(shè)計中，這些操作都是以功能平臺方式組合起來的，列如計算器，無論是電子還是機械的，都要儲存當(dāng)前值，并按要求將該值增1.諸如采用計數(shù)器的電子鐘之類的任一系統(tǒng)要使其存儲和處理能力遍布整個系統(tǒng)，因為每個計數(shù)器都能存儲和處理一些數(shù)字。

Microcomputers use RAM(Random Access Memory), into which data can be written

and from which data can be read again when needed.This data can be read back from

thememory in any sequence desired, and not necessarily the same order in which it was written, hence the expression ‘ random’ access memory.Another type of memory ROM(Read

Qnty Memory)is used to hold fixed patterns of information which cannot be affected by

the microprocessor;these patterns are not lost when power is removed and are normally

used to hold the program which defines the behavior of a microprocessor based system.ROMs can be read like RAMs, but unlike RAMs they cannot be used to store variable information.Some ROMs have their data patterns put in during manufacture, while othersare programmable by the user by means of special equipment and are called programmableROMs.The widely used programmable ROMs are erasable by means of special ultravioletlamps and are referred to as EPROMs, short for Erasable Programmable Read Only Memories.Other new types of device can be erased electrically without the need for ultravioletlight, which are called Electrically Erasable Programmable Read Only Memories, EEPROMs

計算機常使用RAM（隨機存取存儲器），在RAM中數(shù)據(jù)可被寫入，并且在需要時可再次被讀出。這種數(shù)據(jù)能以任一所希望的次序從存儲器中讀出，不必按寫入時的相同次序，所以有“隨機”存取存儲器。另一類ROM（只讀存儲器）用來保持不受微處理器影響的固定的信息標(biāo)本；這些標(biāo)本在電源切斷后不會丟失，并通常用來保存規(guī)定微處理器化系統(tǒng)運轉(zhuǎn)過程的程序。ROM可像RAM一樣被讀取，但與RAM不一樣的是不能用來存儲可變信息。有些ROM在制造時將其數(shù)據(jù)標(biāo)本放入，而另外的則可通過特殊的設(shè)備由用戶編程，所以稱為可編程ROM。被廣泛使用的可編程ROM可利用特殊紫外線燈擦除，并被稱為EPROM，即可擦除可編程只讀存儲器的縮寫。另有新類型的器件不必用紫外線燈而用電擦除，所以被稱為電可擦除可編程只讀存儲器EEPROM。

To employ feedback control, we must first measure the condition we wish to maintain at the desired standard.The condition(variable)may be temperature, pressure, flow,level ,conductivity , pH, moisture content, or the like.要應(yīng)用反饋控制，我們首先必須測出所要維持的某個期望標(biāo)準(zhǔn)的對應(yīng)狀態(tài)。這狀態(tài)（變量）可是溫度、壓力、流量、物位、電導(dǎo)體、pH值、濕度或類似。

System models can be developed by two distinct methods.Analytical modeling consists of a systematic application of basic physical laws to system components and the interconnection of these components.Experimental modeling, or modeling by synthesis, is the

selection of mathematical relationship which seems to fit observed input-output data.系統(tǒng)的模型可以通過兩類截然不同的方法來建立。解析模型是將物理學(xué)基本定律系統(tǒng)性地應(yīng)用于系統(tǒng)各組成部分及其相互之間的關(guān)聯(lián)關(guān)系進而獲取結(jié)果的方法。經(jīng)驗建模，或叫綜合建模，是一種通過尋找數(shù)學(xué)關(guān)系而建立模型的方法，這種數(shù)學(xué)關(guān)系應(yīng)該能夠與輸入-輸出觀測數(shù)據(jù)相配合。

We consider the problem of automatically recognizing human faces from frontal views with varying expression and illumination, as well as occlusion and disguise.We cast the recognition problem as one of classifying among multiple linear regression models and argue that new theory from sparse signal representation offers the key to addressing this problem.This new framework provides new insights into two crucial issues in face recognition: feature extraction and robustness to occlusion.We conduct extensive experiments on publicly available databases to verify the efficacy of the proposed algorithm.我們考慮的問題從正面視圖自動識別人臉不同表達(dá)和照明,以及阻塞和偽裝。
