作業(yè)一：將下列段落翻譯成中文

Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply. It now covers a range of subtopics including power, electronics, control systems, signal processing and telecommunications.

電氣工程是工程的一個領域，一般處理的研究和應用電力，電子和電磁學。本場第一次成為一個可識別的職業(yè)，在十九世紀晚期電報和電力供應的商品化之后。現(xiàn)在它涵蓋的范圍包括副主題電力，電子，控制系統(tǒng)，信號處理和電信。

Electrical engineering may include electronic engineering. Where a distinction is made, usually outside of the United States, electrical engineering is considered to deal with the problems associated with large-scale electrical systems such as power transmission and motor control, whereas electronic engineering deals with the study of small-scale electronic systems including computers and integrated circuits. Alternatively, electrical engineers are usually concerned with using electricity to transmit energy, while electronic engineers are concerned with using electricity to transmit information. More recently, the distinction has become blurred by the growth of power electronics.

電氣工程包括電子工程。其中區(qū)別制成，通常在美國以外，電氣工程被認為是處理與大規(guī)模電力系統(tǒng)如電力傳輸和電機控制有關的問題，而電子工程涉及小型的電子系統(tǒng)的研究包括計算機和集成電路。此外，電氣工程師通常關心的用電來傳輸能量，而電子工程師所關注的用電量來傳遞信息。最近，這種區(qū)分已經(jīng)變得模糊了電力電子技術的發(fā)展。

Power engineering deals with the generation, transmission and distribution of electricity as well as the design of a range of related devices. These include transformers, electric generators, electric motors, high voltage engineering and power electronics. In many regions of the world, governments maintain an electrical network called a power grid that connects a variety of generators together with users of their energy. Users purchase electrical energy from the grid, avoiding the costly exercise of having to generate their own. Power engineers may work on the design and maintenance of the power grid as well as the power systems that connect to it. Such systems are called on-grid power systems and may supply the grid with additional power, draw power from the grid or do both. Power engineers may also work on systems that do not connect to the grid, called off-grid power systems, which in some cases are preferable to on-grid systems. The future includes Satellite controlled power systems, with feedback in real time to prevent power surges and prevent blackouts.

電力工程涉及電力的發(fā)電，輸電和配電以及一系列相關設備的設計。這些包括變壓器，發(fā)電機，電動機，高電壓工程和電力電子。在世界上的許多地區(qū)，政府維護的電氣網(wǎng)絡稱為電力網(wǎng)，與它們的能量的用戶連接在一起的各種發(fā)電機。用戶購買來自電網(wǎng)的電能，避免其產(chǎn)生自己的昂貴的運動。電力工程師可能工作于電力網(wǎng)的設計和維護，以及連接到它的電源系統(tǒng)。這樣的系統(tǒng)被稱為網(wǎng)格上的電力系統(tǒng)，并且可以提供電網(wǎng)與附加功率，從電網(wǎng)汲取的功率或兩者都做。電源工程師也可以工作在不連接到電網(wǎng)系統(tǒng)，被稱為離網(wǎng)發(fā)電系統(tǒng)，在某些情況下是最好的電網(wǎng)系統(tǒng)。未來包括衛(wèi)星控制電源系統(tǒng)，具有實時，以防止電涌和防止停電反饋。
