Electric Power Systems 电力系统 The modern society depends on the electricity supply more heavily than ever before. 现代社会的电力供应依赖于更多地比以往任何时候。
It can not be imagined what the world should be if the electricity supply were interrupted all over the world. 它无法想象的世界应该是什么，如果电力供应中断了世界各地。 Electric power systems (or electric energy systems), providing electricity to the modern society, have become indispensable components of the industrial world. 电力系统（或电力能源系统），提供电力到现代社会，已成为不可缺少的组成部分产业界的。
The first complete electric power system (comprising a generator, cable, fuse, meter, and loads) was built by Thomas Edison – the historic Pearl Street Station in New York City which began operation in September 1882. 第一个完整的电力系统（包括发电机，电缆，熔断器，计量，并加载）的托马斯爱迪生所建-站纽约市珍珠街的历史始于1882年9月运作。 This was a DC system consisting of a steam-engine-driven DC generator supplying power to 59 customers within an area roughly 1.5 km in radius. The load, which consisted entirely of incandescent lamps, was supplied at 110 V through an underground cable system. 这是一个半径直流系统组成的一个蒸汽发动机驱动的直流发电机面积约1.5公里至59供电范围内的客户。
负载，其中包括完全的白炽灯，为V提供110通过地下电缆系统。 Within a few years similar systems were in operation in most large cities throughout the world. With the development of motors by Frank Sprague in 1884, motor loads were added to such systems. This was the beginning of what would develop into one of the largest industries in the world. In spite of the initial widespread use of DC systems, they were almost completely superseded by AC systems. By 1886, the limitations of DC systems were becoming increasingly apparent. They could deliver power only a short distance from generators. 在一个类似的系统在大多数大城市在世界各地运行数年。
随着马达的弗兰克斯普拉格发展在1884年，电机负载被添加到这些系统。这是什么开始发展成为世界上最大的产业之一。
在最初的直流系统广泛使用尽管如此，他们几乎完全被空调系统所取代。到1886年，直流系统的局限性也日益明显。
他们可以提供功率只有很短的距离从发电机。To keep transmission power losses ( I 2 R ) and voltage drops to acceptable levels, voltage levels had to be high for long-distance power transmission. Such high voltages were not acceptable for generation and consumption of power; therefore, a convenient means for voltage transformation became a necessity. 为了保持发射功率损失（我2 R）和电压下降到可接受的水平，电压等级，必须长途输电高。
如此高的电压不发电和电力消耗可以接受的，因此，电压转换成为一个方便的手段的必要性。 The development of the transformer and AC transmission by L. Gaulard and JD Gibbs of Paris, France, led to AC electric power systems. 在发展的变压器，法国和交流输电由L.巴黎戈拉尔和JD吉布斯导致交流电力系统。
In 1889, the first AC transmission line in North America was put into operation in Oregon between Willamette Falls and Portland. 1889年，第一次在北美交流传输线将在俄勒冈州波特兰之间威拉梅特大瀑布和实施。It was a single-phase line transmitting power at 4,000 V over a distance of 21 km. With the development of polyphase systems by Nikola Tesla, the AC system became even more attractive. By 1888, Tesla held several patents on AC motors, generators, transformers, and transmission systems. Westinghouse bought the patents to these early inventions, and they formed the basis of the present-day AC systems.这是一个单相线路传输功率为4,000公里，超过21 V系统的距离。
随着交流的发展多相系统由尼古拉特斯拉，成为更具吸引力的。通过1888年，特斯拉举行交流多项专利电动机，发电机，变压器和输电系统。
西屋公司购买了这些早期的发明专利，并形成了系统的基础，现在的交流。 In the 1890s, there was considerable controversy over whether the electric utility industry should be standardized on DC or AC. By the turn of the century, the AC system had won out over the DC system for the following reasons： 在19世纪90年代，有很大的争议或交流电力行业是否应该统一于直流。
到了世纪之交的，在交流系统赢得了原因出在下面的直流系统为： （1）Voltage levels can be easily transformed in AC systems, thus providing the flexibility for use of different voltages for generation, transmission, and consumption. (1)电压水平可以很容易地改变了空调系统，从而提供了传输的灵活性，发电用不同的电压和消费。 （2）AC generators are much simpler than DC generators. (2)交流发电。
6.WDT的WatchDog Timer看门狗
WDT是英语Watchdog Timer的缩写字母。
Watchdog Timer 中文名看门狗。是一个定时器电路，一般有一个输入，叫喂狗，一个输出到MCU的RST端，MCU正常工作的时候，每隔一段时间输出一个信号到喂狗端，给 WDT 清零，如果超过规定的时间不喂狗，（一般在程序跑飞时），WDT 定时超过，就会给出一个复位信号到MCU，使MCU复位. 防止MCU死机. 看门狗的作用就是防止程序发生死循环，或者说程序跑飞。
工作原理：在系统运行以后也就启动了看门狗的计数器，看门狗就开始自动计数，如果到了一定的时间还不去清看门狗，那么看门狗计数器就会溢出从而引起看门狗中断，造成系统复位。所以在使用有看门狗的芯片时要注意清看门狗。
硬件看门狗是利用了一个定时器，来监控主程序的运行，也就是说在主程序的运行过程中，我们要在定时时间到之前对定时器进行复位如果出现死循环，或者说PC指针不能回来。那么定时时间到后就会使单片机复位。
常用的WDT芯片如MAX813,5045,IMP 813等，价格4~10元不等.软件看门狗技术的原理和这差不多，只不过是用软件的方法实现，我们还是以51系列来讲，我们知道在51单片机中有两个定时器，我们就可以用这两个定时器来对主程序的运行进行监控。我们可以对T0设定一定的定时时间，当产生定时中断的时候对一个变量进行赋值，而这个变量在主程序运行的开始已经有了一个初值，在这里我们要设定的定时值要小于主程序的运行时间，这样在主程序的尾部对变量的值进行判断，如果值发生了预期的变化，就说明T0中断正常，如果没有发生变化则使程序复位。
对于T1我们用来监控主程序的运行，我们给T1设定一定的定时时间，在主程序中对其进行复位，如果不能在一定的时间里对其进行复位，T1 的定时中断就会使单片机复位。在这里T1的定时时间要设的大于主程序的运行时间，给主程序留有一定的的裕量。
而T1的中断正常与否我们再由T0定时中断子程序来监视。这样就够成了一个循环，T0监视T1,T1监视主程序，主程序又来监视T0，从而保证系统的稳定运行。
51 系列有专门的看门狗定时器，对系统频率进行分频计数，定时器溢出时，将引起复位.看门狗可设定溢出率，也可单独用来作为定时器使用.看门狗使用注意：大多数51 系列单片机都有看门狗，当看门狗没有被定时清零时，将引起复位。这可防止程序跑飞。
设计者必须清楚看门狗的溢出时间以决定在合适的时候，清看门狗。清看门狗也不能太过频繁否则会造成资源浪费。
程序正常运行时，软件每隔一定的时间（小于定时器的溢出周期）给定时器置数，即可预防溢出中断而引起的误复位。看门狗运用：看门狗是恢复系统的正常运行及有效的监视管理器（具有锁定光驱，锁定任何指定程序的作用，可用在家庭中防止小孩无节制地玩游戏、上网、看录像）等具有很好的应用价值.系统软件看门狗的设计思路：⒈看门狗定时器T0的设置。
在初始化程序块中设置T0的工作方式，并开启中断和计数功能。系统Fosc=12 MHz,T0为16位计数器，最大计数值为（2的16次方）-1=65 535,T0输入计数频率是.Fosc/12，溢出周期为（65 535+1）/1=65 536（μs）。
⒉计算主控程序循环一次的耗时。考虑系统各功能模块及其循环次数，本系统主控制程序的运行时间约为16.6 ms。
系统设置看门狗定时器T0定时30 ms(T0的初值为65 536-30 000=35 536)。主控程序的每次循环都将刷新T0的初值。
如程序进入死循环而T0的初值在30 ms内未被刷新，这时看门狗定时器T0将溢出并申请中断。⒊设计T0溢出所对应的中断服务程序。
此子程序只须一条指令，即在T0对应的中断向量地址（000BH）写入无条件转移命令，把计算机拖回整个程序的第一行，对单片机重新进行初始化并获得正确的执行顺序。WDT例句及翻译⒈When&how to use watchdog(WDT)&constant ramp time for RAMP command？看门狗（WDT）、RAMP指令对固定斜率时间，何时以及如何使用？⒉In order to improve the reliability and ability of fault-tolerance of CX- 1micro-satellite,hardware fault-tolerance technology such as WDT,EDAC,multi-computer system etc根据小卫星硬件冗余结构的特点，采用了以多版本编程、恢复块技术、前向恢复和后向恢复技术等软件容错技术来提高现代小卫星系统的容错能力。
⒊At the same time the clock chip PCF8563 and serial EEPROM chip CSI24C01 with Reset and WDT circuit of I2C bus are used hi the system. They have not only provided the non- volatility data storage area,the supervision ability of power supply and MCU and the RTC,and its I2C bus structure has been simplified the circuit design.同时在系统中还使用了护C总线结构的时钟芯片PcF8563和内置Reset、wDT电路的串行EEPROM芯片CSI24COI，它们不仅提供了电源和微控制器的监控功能、不挥发性的数据存储区、实时时钟，而且其护C总线结构简化了电路设计。

Tissue Engineering With Electric Fields: Immobilization of Mammalian Cells in Multilayer Aggregates Using Dielectrophoresis ABSTRACT: Positive dielectrophoresis can be used to create aggregates of animal cells with 3D architectures. It is shown that the cells, when pulled together into an aggregate by positive dielectrophoresis in a low-conductivity iso-osmotic solution, adhere to each other. The adherence of the cells to each other is non-specific and increases in time, and after 10–15 min becomes strong enough to immobilize the cells in the aggregate, enabling the ac electric field to be released, and the iso-osmotic buffer to be replaced by growth or other media. Cell viability is maintained. The new method of immobilization significantly simplifies the construction of aggregates of animal cells by dielectrophoresis, and increases the utility of dielectrophoresis in tissue engineering and related areas.
