光伏英文介绍

The basic principle of photovoltaic power generation

1. The composition of a solar photovoltaic system

Solar photovoltaic power generation systems are mainly composed of solar photovoltaic cells, photovoltaic system battery controllers, batteries and AC and DC inverters. The core components are photovoltaic cells and controllers. The role of each component in the system is:

Photovoltaic cells: photoelectric conversion.

Controller: Process control that acts on the entire system. There are many types of controllers used in photovoltaic power generation systems, such as 2-point controllers, multi-channel sequence controllers, intelligent controllers, high-power tracking charge controllers, etc. Most of the controllers currently used in China are simple controllers, intelligent. The controller is only used in communication systems and larger photovoltaic power plants.

Battery: A battery is a key component in a photovoltaic system that stores the power converted from a photovoltaic cell. At present, there is no dedicated battery for photovoltaic systems in China, but a conventional lead-acid battery is used.

AC-DC inverter: Since its function is AC-DC conversion, the most important indicators of this component are reliability and conversion efficiency. The grid-connected inverter adopts the maximum power tracking technology to maximize the power converted by the photovoltaic cells into the grid.

Solar photovoltaic panels:

Solar cells mainly use single crystal silicon as a material. A single crystal silicon is used to make a P-N junction similar to that in a diode. The principle of operation is similar to that of a diode. Only in the diode, it is the external electric field that pushes the holes and electrons of the P-N junction, and the solar photon and the radiant heat (*) that push and influence the hole and electron motion of the P-N junction in the solar cell. This is also known as the principle of photovoltaic effect. At present, the efficiency of photoelectric conversion, that is, the efficiency of photovoltaic cells is about 13%-15% of monocrystalline silicon and 11%-13% of polycrystalline silicon. The latest technology also includes photovoltaic thin film batteries.

3. Classification of solar photovoltaic systems:

At present, solar photovoltaic power generation systems can be roughly divided into three categories, off-grid photovoltaic power storage systems, photovoltaic grid-connected power generation systems, and the first two hybrid systems.

A) Off-grid photovoltaic storage system. This is a common way of solar energy application. It has been used in domestic and foreign countries for several years. The system is relatively simple and adaptable. The range of use is limited only because of the large volume and maintenance difficulties of a series of types of batteries.

B) Photovoltaic grid-connected power generation system, when the power load is large, the solar power is insufficient to purchase electricity from the city power. When the load is small, or when the power is not used, the excess power can be sold to the utility. Under the premise of backing up the grid, the system eliminates the

battery, thereby expanding the scope and flexibility of use and reducing the cost.

C) A, B mixed system, which is the system between the two parties. The program has strong adaptability, for example, it can adjust its own power generation strategy according to the peak and valley electricity price of the grid. However, its cost and operating costs are higher than the above two options.

名家资料英文介绍：奥斯卡·王尔德 Oscar Wilde

Oscar Wilde (1854-1900), Irish poet and dramatist whose reputation rests on his comic masterpieces Lady Windermere's Fan温夫人的扇子(1892) and The Importance of Being Earnest认真的重要性(1895). Among Wilde's other best-known works are his only novel The Picture of Dorian Gray多利安?格雷的画像(1891) and his fairy tales especially "The Happy Prince." Wilde was born on October 16, 1854 in Dublin to unconventional parents - his mother Lady Jane Francesca Wilde (1820-96), was a poet and journalist. His father was Sir William Wilde, an Irish antiquarian古物研究者,收集古物者（antiques）, gifted writer, and specialist in diseases of the eye and ear. Wilde studied at Portora Royal School, Enniskillen, County Fermanagh (1864-71), Trinity College, Dublin (1871-74) and Magdalen College, Oxford (1874-78). In 1878 Wilde received his B.A. and in the same year he moved to London. His lifestyle and humorous wit soon made him the spokesman for

魔方简介

魔方玩魔方的好处：玩魔方是一种高雅的健身活动，它可以锻炼人的手脑并用能力，对培养人的动作技能都十分有效；可增强人的记忆力，丰富空间想象力；可培养人的耐力和毅力。魔方的起源：最早的魔方是匈牙利的一位叫Rubik的教授于1974年发明的，但是这位教授发明它并不是为了投入生产魔方之父Rubik和娱乐。因为他是建筑学和雕塑学教授，所以他自己动手做出了第一个魔方的雏形来帮助学生们认识空间立方体的组成和结构以及锻炼学生的空间思维能力和记忆力。在他完成第一个作品以后，转动了几下，发现原本齐整的魔方竟然很难恢复，于是他意识到这个新的发明会很不简单。但是他想不到的是，这个边长不到6厘米的玩具竟然会在未来风靡全球，甚至出现了以魔方为道具的运动。魔方简介魔方的构造：我们常见的魔方是3x3x3的三阶魔方，是一个正6 面体，有6种颜色，由26块组成，（魔方有8个角色块，12个棱色块，6个中心块，中心块相对位置永远不变，一定是红橙相对，蓝绿相对，黄白相对，也就是相近的颜色相对。中心块是什么颜色，这一面最后就会是什么颜色。大家注意黄白中心块永远是相对的，我们第一步就要用到这个。 3、魔方常见公式符号说明顺时针９０度逆时针９０度顺时针１８０度逆时针１８０度前层 F（front）后层 B（back）右层 R（right）

上层 U（up）不加'代表顺时针旋转90度，公式符号后加'表示逆时针旋转90度，顺逆时针的判断是从所在面的方向来判断的。例如：R'代表右层逆时针旋转90度，是从右边来看的视角逆时针旋转90度，如果从左边来看就会理解反了。再例如B代表顺时针旋转90度，B'代表逆时针旋转90度，这是从B的方向也就是后面来看的视角逆时针旋转90度，B'如果从前面来看，就是顺时针旋转90度，国际规则就是这样定的，这需要我们开始学习的时候就尽快掌握，不能按照自己自以为的理解去看公式，那样就会造成误以为是教程错误的情况或者很多魔友老是没有正确完成步骤的主要原因。插一个小问题，180度旋转为何要分顺逆时针？是否是多余？想一下，是否有想到答案？（正确答案：竞速玩法追求的是速度，为了更快的完成复原，就有更专业的讲究，那就是手法，除了用更短的公式，还要考虑上一步下一步来回还手的顺畅程度，证书基于手法的要求，180度也才有了顺逆的要求，在以后学习高级玩法的过程中，就会慢慢体会到手怎么拿怎么放都是很重要的。）下图是本教程介绍的三阶魔方入门的玩法（层先法）复原的基本步骤示意图：第一步：底棱归位（又称底部架十字，底层四个棱块正确复原的过程）注：（本教程以白色为底面，为了方便交流与学习，请统一把白色作为底面）。魔方底层架十字可以无师自通，只是我们这一步要复原的四个棱块的相对位置顺序要注意，由于我们以白色中心块做底层，按照我们现在的主流魔方的贴纸的帖法（上黄下白，前蓝后緑，左橙右红），如果我们先复原了白蓝这个棱块，那我们在保持白色中心块在底部的情况下，白红的棱块就一点要放在白蓝棱块的右边，白橙棱块放在白蓝棱块的左边，白緑棱块放在白蓝棱块的对面，由于魔方的中心块不会发生变化，所以在复原的过程中，我们是以中心块为参照物的，第一步我们在复原白蓝、白红、白绿、白橙这四个棱块的时候，我们可以先把白色面旋转到顶层，和黄色中心块同一个平面，然后再把他对应的另一个颜色（蓝或红或緑或橙）经过旋转最上层，使之和对应的中心块的颜色同色，这样我们再旋转180度，对应的棱块就正确复原到底部了。注意：图101的情况是没有正确归位的情况，需要调整白蓝和白红两个棱块的位置，才是正确的完成了底棱归位第二步：底角归位（复原魔方第一层四个角块）魔方的四个底角正确归位以后一定会出现倒T字型，如图2所示，如果不是这样肯定是底面角块没有正确归位（位置错了，重新来过）。底角归位也可无师自通，有兴致的朋友可以自己琢磨一些技巧和完成这一步。有难度的朋友可参考我下面介绍的一种技巧来完成，我们先看图2-1和图2-2，首先我们先确定目标块的位置是在他要正确归位的正上面的位置，然后我们再看白色的面朝向何方，就很快的能快速判断出来是下图几种情况中的哪一种了。复原基本思想：先将目标角块调至顶层侧面，再转动能与之相连形成顺色整体的面，使目标角与底棱连成一个(1×1×2)的归位整体，再转至正确的位置。因此，下列的五个实例并没有必要当成公式来死记。

著名景区英文介绍黄山

黄山，位于安徽省南部，地处皖南歙县、黟县和休宁县的边境。面积约1200平方公里，其中精粹风景区约154平方公里。这里，千峰竞秀，有奇峰72座，其中天都峰、莲花峰、光明顶都在海拔1800米以上，拔地极天，气势磅礴，雄姿灵秀。黄山，中国十大风景名胜之一，90年被联合国教科文组织列入“世界文化与自然遣产”名录，蜚声中外，令世人神往。黄山集名山之长，泰山之雄伟，华山之险峻，衡山之烟云，庐山之瀑，雁荡之巧石，峨嵋之秀丽，黄山无不兼而有之。明代旅行家、地理学家徐霞客两游黄山，赞叹说：“登黄山在下无山，观止矣！”又留下“五岳归来不看山，黄山归来不看岳”的美誉。 Of all the notable mountains in China, Mount Huangshan, to be found in the south of Anhui province, is probably the most famous. Originally known as Mt. Yishan it was renamed Mt. Huangshan in 747 AD in recognition of the legendary Huang Di, who was the reputed ancestor of the Chinese people and who made magic pills for immortality here. Wu yue is the collective name given to China's most important mountains, namely Mt. Taishan in Shandong Province, Mt. Huashan in Shaanxi Province, Mt. Hengshan in Shanxi Province, Mt. Songshan in Henan Province and Mt. Hengshan in Hunan Province. It is said that you won't want to visit any other mountains after seeing wu yue but you won't wish to see even Wu Yue after returning from Mt. Huangshan. This saying may give you some idea of the beauty and uniqueness of Mt. Huangshan. Together with the Yellow River, the Yangtze River and the Great Wall, Mt. Huangshan has become one of the great symbols of China. Mt. Huangshan can boast not only of its magnificence but also its abundant resources and great variety of zoological species, for which it has been listed as a World Natural and Cultural Heritage Site. 更多英语学习：企业英语培训https://www.wendangku.net/doc/b412704583.html,/
