Therefore,the rotors of all interconnected machines must be in synchronism.In a generator,the electromagnetic torque opposes rotation of the rotor,so that mechanical torque must be applied by the prime mover to sustain rotation. 译文： 当两个或多个同步机互相联系,定子电压和电流的所有的机器必须有相同的频率和转子机械速度同步都是这个频率。因此,转子相互联系的机器必须在同步在一般的发电机里,电磁转矩转子旋转反对,使机械扭矩必须采用原动机来维持旋转。 The effect of increasing the mechanical torque input is to advance the rotor to a new position relative to the revolving magnetic field of the stator. Conversely, a reduction of mechanical torque or power input will retard the rotor position.In a synchronous motor, the roles of electrical and mechanical torques are reversed compared to those in a generator. 译文： 对提高的机械转矩输入是为了增进转子到一个新的位置相对于旋转磁场的定子。相反,减少了机械扭矩或输入功率转子位置会妨碍在同步电动机的角色、电气、机械反扭矩相比,那些在发电机。 For satisfactory operation of a power system, the frequency should remain nearly constant.Relatively close control of frequency ensures constancy of speed of induction and synchronous motors. Constancy of speed of motor drives is particularly important for satisfactory performance of all the auxiliary drives associated with the fuel, the feed-water and the combustion air supply systems . In a network,considerable drop in frequency could result in high magnetizing currents in induction motors and transformers. 译文： 获得满意的电力系统的运行、频率应该保持接近恒. 比较近的频率控制确保恒久的引申和同步电动机速度。电动机驱动的速度恒久的满意的效果尤为重要,各项配套驱动有关的燃料、给水及燃烧送风系统。在网络中,相当大的下降可能导致高频率异步电动机电流磁化和变压器。3、 短文翻译 可再生能源简介 为产生能源在矿物燃料在燃烧是气候发生变化的主要原因。煤、油和气体的燃烧产生的二氧化碳引起全球变暖的主要导致温室效应的气体之一。 为了解决气候改变、找到一种将来使用的绿色能源，我们迫切需要采取更有效的技术降低能源使用，从可再生物质中产生能量，释放更少或不释放二氧化碳进入大气层。 可再生能源技术（诸如风、海浪、潮汐、水力发电和生物能栽培和燃烧家作物而发能）可提供“清洁的”无碳能源，作为矿物燃料（气、油、煤）的替代物，它通常用于加热和发电。（生物能除外，尽管它的确释放二氧化碳，但它只是把植物一生中通过光合作用吸收的二氧化碳释放到空气中）。 与此相反，燃烧矿物燃料将二氧化碳排放到大气层中，位于地球表面的大气层已存在数亿年。矿物燃料的来源是有限的，因此它们的持续使用是不可能的。可再生技术是一种可持续的产生能源地方法，因为风、海浪、太阳能等等是不可能耗尽的。可再生能源如下：太阳能 太阳给有的生物提供一种基本的能量。太阳能是免费和用这不竭的。将阳光转换为人类消费的形式产生成本。数千年来阳光被人类用来晒干农作物、加热水和建筑。二十世纪采用的是光电技术，即将阳光直接转换为电。 风能 空气的运动可被用来作为能源，从远古时代即是如此。今天先进的空气动力学研究已研究出风力涡轮机，它可以非常经济地发电。风力涡轮机通常成组地置于农场，位于沿海或山顶地乡村开阔地带，那里全年都有盛行风。 地热能 在地球硬壳下面的岩石含有像铀、钾等一直在衰减的放射性材料，这些材料持续不断地提供热能。在地球表面10000米深范围内的热量比世界上所有的油和气源所包含的能量的50000倍还要多。 地热能传导地壳下面的加热水。热虽被用来驱动电涡轮机和加热建筑。具有最高温度的区域于活跃的或新形成的火山地区周围。 生物能 生物是我们用来描述产生能量的植物材料和动物废弃物地术语。植物形成了地球上所有生物赖以生存的食物链的基础。但以生产能量的观点，“生物”指的是利用树、农作物、森林、农业和城市的废弃物。它是人类最早知道的可再生能源。生物是一种可再生能源，因为它含有来自太阳的能量。通过光合作用，植物上的叶绿素通过将空气中的二氧化碳和土壤中的水转成碳水化合物捕捉到了太阳能。译文：Renewable energy profileTo produce energy in fossil fuels in combustion is the main cause of climate change. Coal, oil and gas carbon dioxide from the burning of global warming caused by the main one of heat-trapping greenhouse gases.In order to tackle climate change, find a future use of green energy, so we need to take more effective technology to reduce energy use, from renewable material produces energy, release less or not release carbon dioxide into the atmosphere.Renewable energy technologies (such as wind, tides, waves, hydroelectric and bio-energy cultivation and burning house plants and hair can) can provide clean no carbon energy, as fossil fuels (gas, oil, coal) substitute, its usually used for heating and power generation. (except unaltered, although it does carbon dioxide, but it just put the plant life through photosynthesis absorb carbon dioxide into the air).By contrast, burning fossil fuels would carbon dioxide into the atmosphere, located on the surface of the earths atmosphere already exist millions and billions of years. Fossil fuel source is limited, and therefore their continuous use is impossible. Renewable technology is a kind of sustainable energy production to methods, because the wind, the sea, the solar energy, etc, are impossible exhausted.Renewable energy is as follows:Solar sun to some biological provides a basic energy. Solar energy is free and use this inexhaustible. Sunlight converted to human consumption forms produce cost. For thousands of years by humans to sunshine dry crops, heating water and buildings. The twentieth century USES is photoelectric technology, forthcoming sunlight directly convert electricity.Wind air movement can be used as the energy from ancient times namely is so. Todays advanced aerodynamic studies had developed the wind turbines, it can be very economic power. Wind turbines usually group exactly where the farm, in the coastal or mountain to rural open areas, where the prevailing winds throughout the year.Geothermal energy in earths mantle below rocks contain, such as uranium, potassium, etc have been attenuation of radioactive materials, these materials continuously provide heat. The surface of the earth 10,000 meters deep within the scope of the heat than all of the world oil and air contains energy 50000 times higher than.Geothermal energy condu
