電力和電路的來源
One of them is the electric cell, or battery, which generates electricity by chemical action. The other device called generator makes use of light, heat, and mechanical motion to produce electric energy. Now, more than 95 percent of the world's electric energy is produced by generators其中之壹是由化學作用產生電力的電池的電的單元格。調用生成器使其他設備使用的光、 熱和機械的運動來產生電能。現在,世界電力能源的 95%以上是由發電機產生的
An electric current is a constant flow of electrons through a conductor. The reason why an electric current flows through conductors is much like reason why water flows through mains. 源源不斷地通過導體電子的電流。為什麽電流流經導線的原因很多像為什麽水流通過水管的原因。
智能機器人
An entirely new phase in robotic applications has been opened with the development of “intelligent robots”. An intelligent robot is basically one that must be capable of sensing its surroundings and possess intelligence enough to respond to a changing environment in much the same way as we do. Such an ability requires the direct application of sensory perception and artificial intelligence. Much of research in robotics has been and is still concerned with how to equip robots with visual sensors-eyes and tactile sensors-the “fingers”. Artificial intelligence will enable the robot to respond to and adapt to changes in its tasks and in its environment, and to reason and make decisions in reaction to those changes.壹個全新的階段,在機器人的應用程序中已打開的"智能機器人"發展。壹個智能機器人基本上是壹種必須能夠感知周圍的環境並擁有足夠的智能響應不斷變化的環境壹樣,我們做的。這種能力需要感官知覺與人工智能技術直接的應用。多機器人的研究壹直,仍然關註如何使機器人視覺傳感器眼睛和觸覺傳感器在"手指"。人工智能技術將使機器人響應和適應其任務和它的環境變化的原因和反應對這些變化做出的決定。
Integrated circuit
集成電路
The invention of IC is a great revolution in the electronic industry. Sharp size, weight reductions are possible with these techniques; and more importantly, high reliability, excellent functional performance, now cost and low power dissipation can be achieved. ICs are widely used in electronic industry.集成電路的發明是大革命在電子工業中。鋒利的大小重量減少有可能與這些技術 ;和更重要的是現在成本的優良性能的高可靠性和可以實現低功耗。集成電路 廣泛應用於電子行業。
The electrically interconnected components that make up an IC are called integrated elements. If an integrated circuit includes only one type of components, such as only diodes or resistors, it is said to be an assembly or set of components.芯片組成的電互連的組件稱為集成的元素。如果壹個集成電路包含壹種類型如僅二極管或電阻的組件的據說是壹個程序集或壹組組件。
Digital integrated circuit can contain anything form a few thousand to millions of logic gates, flip-flops, multiplexers, and other circuits in a few square millimeters. These digital ICs, typically microprocessors, digital signal processing, and micro controllers work using binary mathematics to process “one” and “zero” signals.數字集成電路可以包含任何內容形成數千數以百萬計的邏輯門、 觸發器、 多路復用器和其他線路的幾個平方毫米。這些數字集成電路、 通常微處理器、 數字信號處理和微控制器工作使用二進制的數學處理"1"和"零"的信號。

要使用您的 GSM 服務在美國嗎?
攜帶此小件行李。
如果您正在前往美國,壹定要帶上您的 SIM 卡。因為您的 GSM 服務可以像工作在美國它劑量在家裏。
妳要做的是租住在美國使用合適的頻率手機。(如果您不具有您的 SIM 卡,放松。我們會提供壹個手機 SIM 卡包括。)
在其他的國家壹樣,妳會發現使用 GSM 在美國通常是少比電話卡、 電話和酒店電話。的課程,更方便
妳要享受 GSM 方便做的只是調用下面列出的數字之壹。我們會提供租 24 小時,或在壹些的城市非常同壹天手機。

Computer Control Technology
A computer is a fast and accurate symbol manipulating system that is organized to accept, store ,and process data and produce output results under the direction of stored program of instructions. This section explains why a computer is a system and how a computer system is organized. Key elements in a computer system include input, processing, and output devices. Let's examine each computer of the more detail.
計算機是壹種快速而又準確的操縱系統,為了接受、 存儲,和處理的數據並產生輸出結果存儲程序的指導下的指令的快速、 準確的符號。此部分說明為什麽壹臺計算機是壹個系統和計算機系統的組織方式。計算機系統中的關鍵元素包括輸入、 處理,和輸出設備。讓我們看壹下每臺計算機的更多詳細信息。
Central Processing Unit the heart of any computer system is the central processing unit (CPU). There is three main sections found in the CPU of a typical personal computer system: the primary storage section, the arithmetic-logic section, and the control section. Bit these three sections aren’t unique to personal computers. They are found in CPUs of all sizes.
中央處理器是任何計算機系統的核心是中央處理單元 (CPU)。有三個主要部分,在典型的個人計算機系統的 CPU 中找到: 主存儲部分、 算術邏輯部分和控制部分。位這三個部分不是唯壹的個人計算機。他們有各種規模的CPU。
Output Devices Like input units, output devices are instruments of interpretation and communication between humans and computer systems of all sizes. These devices take output results from the CPU in machine-coded form and convert them into a form that can be used (a) by people (e.g., a printed and/or displayed report) or (b) as machine input in another processing cycle.
輸出設備 如同輸入設備,輸出設備是文書的解釋和人與各種規模的計算機系統之間的 通信 。這些設備從CPU的輸出結果以機編碼的窗體,並將它們轉換為壹個窗體,可以在另壹個處理周期中使用(a)的(例如,印刷和/或顯示報告),或(b作為輸入機。
In personal computer systems, display screen and desktop printers are popular output devices. Larger and faster printers, many online workstations, and magnetic tape drives are commonly found in larger systems.
在個人計算機顯示屏幕和桌面打印機是受歡迎的輸出設備。更大、 更快的打印機、 很多的在線工作站和磁帶驅動器通常有較大的系統。
The operating system must ensure correct operation of the computer system. To prevent user programs from interfering with the proper operation of the system, the hardware was modified to create two modes: user mode and monitor mode. Various instructions (such as I/O instructions and halt instructions) are privileged and can only be execute in monitor mode. The memory in which the monitor resides must also be protected from modification by the user. A timer prevents infinite loops. Once these changes (dual mode, privileged instructions, memory protection, timer interrupt) have been made to the basic computer architecture, it is possible to write a correct operating system.
操作系統必須確保計算機系統的正確操作。防止在幹擾系統的正確操作用戶程序修改硬件創建兩種模式: 用戶模式和顯示器模式。(例如,I/O 指令和停止指令) 的各項說明享有特權,並且只能在顯示器模式下執行。顯示器所駐留的內存也必須由用戶修改保護。計時器可防止無限循環。壹旦到基本的計算機體系結構做了這些更改 (雙模式、 特權的指令、 內存保護、 計時器中斷),就可以編寫正確的操作系統。
Completes with the digital signal to the digital quantity carries on the arithmetic operation and the logic operation circuit is called the digital circuit, or number system. Because it has the logic operation and the logical processing function, therefore calls the numeral logic circuit.
完成與數字信號,數字的數量進行算術運算和邏輯操作電路被稱為數字電路或數字系統。因為它有邏輯操作和邏輯處理功能,因此呼籲數字邏輯電路。
Karnaugh Map consists of one square for each possible minterm in a function. The method to write the Karnaugh Map: When we plot a function, we put a 1 in each square corresponding to a minterm that is included in the function, and put a 0 in or leave blank those squares not included in the function.
卡諾圖包含每個可能的最小項函數中的壹方。寫入卡諾圖的方法:當我們繪制壹個函數時,我們放在壹個最小項的函數中包含的每個平方米對應的 1 和放壹個0或保留為空函數中不包括這些方塊。
