作业一：将下列段落翻译成中文
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.
电气工程是工程的一个领域，一般处理的研究和应用电力，电子和电磁学。本场第一次成为一个可识别的职业，在十九世纪晚期电报和电力供应的商品化之后。现在它涵盖的范围包括副主题电力，电子，控制系统，信号处理和电信。 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.
电气工程包括电子工程。其中区别制成，通常在美国以外，电气工程被认为是处理与大规模电力系统如电力传输和电机控制有关的问题，而电子工程涉及小型的电子系统的研究包括计算机和集成电路。此外，电气工程师通常关心的用电来传输能量，而电子工程师所关注的用电量来传递信息。最近，这种区分已经变得模糊了电力电子技术的发展。
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.
电力工程涉及电力的发电，输电和配电以及一系列相关设备的设计。这些包括变压器，发电机，电动机，高电压工程和电力电子。在世界上的许多地区，政府维护的电气网络称为电力网，与它们的能量的用户连接在一起的各种发电机。用户购买来自电网的电能，避免其产生自己的昂贵的运动。电力工程师可能工作于电力网的设计和维护，以及连接到它的电源系统。这样的系统被称为网格上的电力系统，并且可以提供电网与附加功率，从电网汲取的功率或两者都做。电源工程师也可以工作在不连接到电网系统，被称为离网发电系统，在某些情况下是最好的电网系统。未来包括卫星控制电源系统，具有实时，以防止电涌和防止停电反馈。
