学习古筝要先有浓厚的兴趣，兴趣是最好的教师，没有兴趣学什么都提不起精力，只会浪费时间。因而学古筝必定要本人发自内心的喜爱，那样才能学得更好。
了解古筝
古筝又名汉筝、秦筝、瑶筝、鸾筝，是中国汉民族传统乐器中的筝乐器，属于弹拨乐器。它是中国独特的、重要的民族乐器之一。它的音色优美，音域宽广、演奏技巧丰富，具有相当强的表现力，因此它深受广大人民群众的喜爱。
古筝的种类
古筝分低档古筝、中档古筝、高档古筝三种。
一、低档古筝是由普通木板做出框架，做工较粗躁，以花梨酸枝木贴皮，这种古筝声音较闷，弹不出古筝的韵味儿。
二、中档古筝琴是由花梨木酸枝木胡桃木做古筝的琴头琴尾，以及侧板，面板采用泡桐木，这种琴做工规范，弹出了古筝的韵味，但和中高档琴比音色要逊色很多。
中高档古筝是采用黑檀木老红木做古筝的琴头琴尾，以及侧板，面板采用泡桐木，这种材料做出的古筝音色清脆，韵味渐浓。
三、高档古筝做工严谨，选料精细，采用紫檀木血檀（雪檀）木做古筝的琴头琴尾，以及侧板，面板采用优质泡桐木。
近年雪檀已尽绝迹，紫檀也越来越少，这种材料做出的古筝音色纯正，颗粒性强，琴声韵味十足，余音较长，即余音绕梁乃三日不绝。
古筝分南北吗？
因为北方气候干燥，古筝使用中容易开裂，所以就流传出南筝、北筝的说法。
其实古筝是不分南北筝的，有些商家就是抓住了“古筝开裂”这一痛点，推出了南北筝这一概念。
古筝是不分南北的，也就是不分南北用琴。古筝核心面板都是泡桐木，泡桐木产自河南兰考，如果将河南产的面板拿回上海加工就成了南方古筝，拿回西安加工就成了北方古筝，这显然是说不通的。买古筝时最重要的是买适合自己的筝，且注意对其保养就行。
古筝琴弦
古筝是中国古老的民族乐器，距今已有两千五百多年的历史。
标准古筝有21根弦。从最细的弦到最粗的弦，依次编号为1~21。
最初的古筝，只有5根弦。经秦国著名将蒙恬改造后，古筝发展到12弦。在当时的历史条件下，应该说是对古筝成功的改革。12弦古筝延续使用了数百年，直到唐朝后期才出现了13弦古筝。
随着时代的发展，古筝的弦数也越来越多，音域也越来越宽。出现了16弦、18弦、19弦、21弦、23弦、25弦等，直到今天，发展成为通用的21弦。
筝身长1.63米的21弦古筝，被称为标准筝。筝弦，也由过去的丝，动物筋等生物性材料制作，改为现在的钢丝弦和尼龙缠弦。
随着筝弦的增加，筝的体积也在增大。发展到今天，已成为一种古朴典雅的民族乐器。
古筝基础知识
古筝的定义：弹拨弦鸣乐器。
一共有 21 根琴弦，包含 17 根弦和 4 根绿弦
1、琴弦：现多用尼龙缠弦，以不同型号的钢丝外面缠以尼龙丝制成的。
2、琴码（又称：雁柱）：支撑琴弦，琴码的右侧为演奏区域，左侧为左手补韵的装饰音区域。
3、岳山：分为前岳山，后岳山，分别镶嵌在琴面板的首部和尾部。
4、面板：琴面略有弧度的木板。
5、调弦盒：内有弦轴，用于调音；琴盒内可以放指甲，琴扳手等物件。
认识SOL
认识简谱
简谱：简谱中用以表示音的高低及相互关系的基本符号为七个阿拉伯数字，即１、２、３、４、５、６、７，唱作do、re、mi、fa、sol、la、xi，称为唱名。
唱名：do re mi fa sol la xi
音名：C D E F G A B 这个就是用来记固定音高的符号。
在简谱中表达高低音一般会在上下两个方向添加小圆点。
中音是１２３４５６７那么低音表达就是在这些数字现面加一个小圆点，高音就是在数字上面加一点，上面加二个点为倍高音，加三个点为超高音。反之下面亦如此为倍低音、超低音等以此类推。
除了音的高低外，简谱还有一个重要的因素就是音的长短，简谱音的长短有多种表达方式，如基本的加小横线的方式。

五声调音
古筝采用的是五声音节，由这五个音构成的调式是五声调式。所以古筝琴弦上没有4（fa）和7（si）。
琴弦排列分组
筝架和姿势
弹筝的姿势有多种，一般采用坐式，要求坐姿端正，精神饱满、动作自然。古代采用过盘式、跪式。
由于流派的不同，筝的放置位置、筝架、琴凳也不同。
有的用琴桌式筝架，有的用类似人字形的筝架，还有的就放在腿上演奏。
采用琴桌式筝架比较稳因、牢靠，琴桌的面板有助于筝的共鸣。琴桌的大小应适当，恰好放稳筝的四个角；筝与琴桌之间有一定的空隙，以便于出音；琴桌的高低适合放腿为宜。此外，琴桌的造型应美观大方。
如采用类似人字形折叠筝架，应注意筝体能放置平稳，避免演奏中摇晃。
如采用小筝放在腿上演奏，小筝筝头底部应加筝托，以防止上身过前倾，腿部不要挡住出音孔，琴凳不要过高，筝尾支架的高度应与琴凳高度相当或略高。琴凳离筝体要近，尤其弹奏宽大的、弦数多的筝，一般身体前侧距筝体大约有6厘米至10厘米，应坐在靠近前岳山的位置上，坐的高低位置，应以方便演奏，便充分发挥技巧为原则。身体离琴过远，将使右手演奏困难，影响对触弦的控制；离琴过近，左手按弦困难，右手拨弦不方便；坐的位置过高时，上身容易前倾；坐的位置过低时，容易紧张。
弹筝的姿势，一般采用坐式，演奏者坐的姿势应该是：两腿自然分开，上身端正，两臂和双手松弛而自然抬起，精神饱满，态度自然。在演奏时既不要驼背也不要过分挺胸；既不要拘紧，也不要松垮。切忌摇头晃脑、脚打拍子等坏毛病。
正确的演奏姿势是：右脚蹬在固定筝架的踏板上，头部略俯视，双手按乐曲开头的指法自然伸出，做好弹奏准备。
如何选择古筝
古筝的统一规格为：1.63米，21弦。一台古筝的音质取决于面板和琴弦，面板以阳面中段为最佳，阳面是指整株桐木置于水中，露出水面的一面为阳面，去头斩尾为中段，一般以9-12年树龄的桐木为最佳，尤以河南兰考的桐木为最佳，沙土地，木质疏松，利于音质的传导。
初学者在购买古筝的时候一般不知道如何选择，市场上售卖的有练习筝、演奏古筝两种。
练习筝的制作较为简单，一般都是不包边的，而演奏筝的工艺更复杂，也更精美。 同时，会因为木头的品质，和穿弦孔的工艺不同而导致音色和手感的不同。
演出筝对音色的要求更严格，音色要亮，所以价格一般比练习筝的价格贵。
古筝的结构说简单也简单，但是要让这简单的结构发出美妙的音乐就是技术活了。决定音色品质重要的部分是面板的等级，其次筝码、整体做工、制作工艺等，边板材质起到装饰古筝的作用，不建议作为选筝的重点。
古筝作为乐器其音色品质才是其价值的体现，而价值也是决定价格的原因，这也就是为什么古筝的价格会有如此大的差异。
我们选购古筝的时候首先要考虑古筝的音色问题，购买音色较好的古筝，如果是作为古筝学习者，练习筝也不要买太次的，那会影响自己的听力，和审美标准。
学习古筝
学戴义甲
大指：将义甲戴在指肚上，向指尖左上方斜出45度佩戴
食指、中指：将义甲戴在指肚上，顺指甲生长方向直戴
注意：佩戴时义甲不要挡住手指的关节；胶布的一半应覆盖在自己本身的指甲上。
选择指甲
古筝指甲首先要选择合适自身手指的长度，选择的指甲要和自己的手指第一节的长度相匹配，通常都是选择中号。指甲面选择宽点、上方尖点，不需要太厚的指甲面。古筝指甲材质很多，有塑料、树脂、玳瑁的，三种材质对比，玳瑁的比其它两种的好，对琴弦没有多大的磨损，但价格比较贵，塑料和树脂对琴弦的磨损就比较严重。
挑选玳瑁方法
1、强光照射法：把玳瑁放在太阳底下或者电筒光下投射，如果看见花纹、透明血丝状在甲片里，就是真品。伪劣产品呈现的血丝在甲面上是片状的，还有斑纹呆板或者团块状。
2、燃烧法：刮一点点的指甲点燃，或者用加热的针触碰指甲面，真品就会散发出烧焦头发的味道，伪劣产品是散发其它的味道，比如樟脑的味道、塑胶的味道、醋味等。
分辨琴弦
古筝的琴弦有21根弦，共有两种颜色，白色琴弦、绿色（或红色）琴弦。
绿色（或红色）琴弦都唱“5”（sol），共有四根绿色（或红色）琴弦，有粗有细，由细到粗，分别代表
高音5；中音5；低音5；倍低音5
第一根到第五根琴弦为倍低音，表示方法是在1、2、3、5、6下面加两个点;接下来五根弦是低音,在1、2、3、5、6，下面点一个点;在后面五根弦是中音区,1、2、3、5、6。接下来是高音区,五根弦1、2、3、5、6上方加一个点;最后一根为倍高音do,1上面加两个点。
练习古筝步骤
弹古筝,首先要保持正确的姿势。两只手的食指、中指、大指依次配戴好指甲，你可以买两卷医用胶带，一卷放手上保持手背的平直，另一卷用来配戴指甲。
眼睛平视乐谱，身体坐好，接下来开始古筝的练习。
佩戴指甲
弹奏古筝之前先要佩戴好指甲，指甲的大小应和手指第一关节差不多，戴在第一关节往上一点，胶布缠在第一关节中间，不要影响关节活动处，大指缠带方法与其他指不同，假指甲向内与指尖呈45度角，左右相对。
熟悉古筝音阶
音乐的七个基本音阶1(do)2(re)3(mi)4(fa)5(sol)6(la)7(si)，古筝是五声音阶，没有4和7，只有1、2、3、5、6。
练习古筝指法
古筝演奏中常用到指法：勾、托、抹、劈、剔、挑、提、花指、摇指、琶音、泛音、按音、揉音、大撮、小撮、颤音、滑音等。
托-大拇指向外弹弦。
劈-大拇指向里弹弦。
抹-食指向里弹弦。
挑-食指向外弹弦。
勾-中指向里弹弦。
剔-中指向外弹弦。
提-无名指向里弹弦。
连托-大拇指向外连续弹弦。
连抹-食指向外连续弹弦。
大撮-大拇指向外，中指向里同时弹两弦。
小撮-大拇指向外，食指向里同时弹两弦。
双托-大拇指同时向外弹奏邻近的两弦。
双抹-食指同时向外弹奏邻近的两弦。
八度双托-大拇指向外弹奏邻近的两弦，同时中指在低八度另一音，三阴同时奏响。
摇指-大拇指连续托劈。
琶音-左手或右手用三个或四个手指按顺序弹奏不同的音。
泛音-左手食指在发音弦1/2处轻贴弦，右手弹弦发音。
花指-大拇指迅速连托数弦。
向上刮奏-在筝弦上由低音向高音的划奏。
向下刮奏-在筝弦上由高音向低音的划奏。
揉音或颤音-根据音乐的不同风格分类，是揉音类的，揉动较平和；是颤音类的，音波较密，也较有地方风格。
重颤音-用力较重的颤音。
按音-在弦上按出的音。
上滑音-右手弹弦后，左手按弦，使音由低向高滑动。
下滑音-左手先按弦，右手弹奏后逐渐松弦。
回滑音-右手弹弦之后，左手按弦使音由低向高又有高向低滑动数次。
左手点音-左手马子左侧先轻点或轻轻快速下滑。

练习曲子
曲子是一句一句，一段一段地练习的，练得多了自然就记住了，然后可以脱离琴谱练习。
代表曲目
古筝十大代表名曲有《渔舟唱晚》、《高山流水》、《寒鸦戏水》、《汉宫秋月》、《蕉窗夜雨》、《林冲夜奔》、《侗族舞曲》、《东海渔歌》、《香山射鼓》、《战台风》。
《渔舟唱晚》是传统的古筝独奏名曲。一般以为此曲是娄树华在20世纪三十年代中期，根据古曲《归去来辞》的素材改编而成。取自唐朝诗人王勃的名篇《滕玉阁序》中的佳名：“渔舟唱晚，响穷彭蠡之滨”。
《高山流水》，为中国十大古曲之一。此曲最早见于我国现存最早的琴曲集《神奇秘谱》。乐曲取中国古代著名的音乐故事“伯牙摔琴谢知音”为题材，表现一种“巍巍乎若高山，洋洋乎若江海”的境界。
《寒鸦戏水》寒鸦又名鸥鸟，这是一首有名的潮州筝曲，是潮洲弦诗《软套》十大曲中最富诗意的一首。
老师指导
学习古筝需要有一个好老师指导，古筝作为一种并不那么容易学成的乐器，单靠自学是很困难的，因此需要找一个好老师。专业的好老师保证你能学到规范的指法、技巧和乐曲处理，不至于走弯路。
业余爱好者自学时，虽然有入门教材的辅导，但是自学难免会遇到许多不懂的地方，这时候就需要专业的老师进行解答了。其实刚开始的时候可以看视频资源、与许多古筝专业者或爱好者交流，不懂时还可以提出问题，这样总比自己一个人探索有用得多。
古筝是一门入门容易精通难的乐器，尤其是业余爱好者没有人监督，就更容易放弃，所以坚持才能成功。
选择古筝老师需要注意以下几点：
1、口碑；
大家选择古筝老师的时候还是要非常注重口碑的，如果身边有周围的朋友在学习古筝，我们不妨参考一下朋友的意见，老师的口碑如果好了，一般教学质量都挺不错的。
2、要去试听课；
古筝课都是可以提前试听的，我们可以参加基础的试听课程，如果你认为老师讲的可以很轻易的听得懂，而且讲的有非常详细，老师人也比较好，那么就可以考虑选择这个老师。
3、学历；
老师的学历也是比较重要的，我们在选择老师的时候我可以咨询一下老师是哪里毕业的，如果老师是正规的音乐学校毕业的，那么他学习的知识会更加系统，在教我们的时候条理会特别清楚。
4、专业性。
学习古筝还是非常需要老师的专业性的，老师水平比较高，比较专业，那么我们的学习质量也会更加的高。
自学选择教材
1、《古筝基础教程》
这本书分为古筝入门、古筝技法、古筝曲三个部分，是结合理论和实际的基础教材。
2、《古筝入门》
这本书介绍古筝由易到难，循序渐进，介绍的比较详细，里面附带很多筝曲。
3、《从零起步学古筝》
遵循从易及难的原则，从古筝最基本的指法讲起，每种指法配以相应的练习曲和乐曲。
我们学习的时候先学习基础知识，理论知识学会后可以在网上多看些古筝的教程，特别的视频教程，可以在哔哩哔哩上选择适合自己的配合教材学习。
不过刚开始学习还是不建议自学，毕竟我们对古筝琴音没用正确的认知，非常容易走入误区，只有在老师的带领下，感受到老师正确的琴音，才能慢慢培养认知，这个是教材和视频代替不了的。
古筝考级
古筝考级分为1-10级，其中1-4级为初级，5-7级为中级，8-10级为高级，高级需要加考乐理。
按有关规定，古筝考级一般是从一级到十级，由低到高逐级考评，但由于考级工作一般都是每年进行一次，而学古筝的每个人学习情况不同，因此可跳级报考，如果古筝学习的比较好，可以直接报考六级考试。
六级考试属于中等偏上的等级考试，考试相对简单，7级开始考试难度会增加很多。
所以刚开始考级的时候建议选择古筝六级考试，下面给大家介绍一些六级考试曲目。
古筝六级曲目有哪些
古筝考级六级曲目一般包括《高山流水》、《柳青娘》 、《出水莲》、《崖山哀》、《庆丰年》 、《闹元宵》 、《山丹丹开花红艳艳》等，根据考级版本不同可能略有区别，例如有音协考级、中央音乐学院考级、民族管弦学会考级等， 每个版本曲目和练习曲要求都不同。
考级的时候需要演奏两首同一级别的曲目，六级曲目中高山流水、庆丰年 、出水莲为必选曲目。六级考试的要求是加强各种音色变化、控制力的训练，并进行一些特殊定弦乐曲的练习，演奏上必须按照其指法特点，应强调力度与音色的对比、演奏的投入及较好的音乐表现力。
调音器怎么用
古筝和吉他、钢琴等乐器一样都是需要调音的，最简单的方法就是使用调音器进行调音，具体的方法如下：
1、首先把调音器的电池装好，长按中间的开关打开调音器。
2、按开关键把屏幕左下角的字换成“自动”，按“M/T”键把屏幕右下角的字换成“古筝D”。
3、按上三角符号和下三角符号把左上角的数字换成“=440”。
4、把夹子夹到要调的那根弦的附近，这样更能使调音器取到音。
5、用古筝指甲拨要调的那根弦，看调音器屏幕上的数字，如果显示的数字比调的弦大，就说明太松了，如果数字比调的弦小，就说明太紧了，用调音扳手重新调整。
6、当屏幕上的数值是所调的弦的数值，还要看调音器最上端的三个指示灯，如果左边的红灯亮了，就说明有点偏紧了，如果右边的红灯亮了，就说明有点偏松了，如果绿灯亮，就说明这条弦已经调好。
日常保养方法
一般情况下，相对湿度在50%-70%之间的空间内使用古筝对筝的振动和发音都比较有利，湿度低于50%容易引发筝体表面及底板开裂，而湿度高于70%则易使面板吸潮，导致声音发闷、余音减短、音色发暗。
1、古筝在使用时应轻拿轻放，避免碰撞或剧烈震动。
2、若在北方地区使用古筝，在琴下放一盆水，增加空气湿度，防止开裂。冬季时古筝不能靠近散热的暖气片，以免出现曝烈或变形的情况。
3、古筝使用后可用干软布拭去琴弦上的汗渍，以防琴弦生锈，不用时要以筝罩盖好;
4、古筝应经常使用，这有利于琴弦张力的稳定，也鞥促进音色;
5、一旦发现琴音不准时应及时调音;
6、长时间不用古筝，只要防潮、防晒、防灰即可，不可将其放在地上或挂在潮湿的墙上。湿气较重时，将古筝放入盒内，并在盒内放入干燥剂。

5. dt830b数字万用表元器件清单
电脑不仅能帮助我们快速完成重复性的工作，而且提供了一种休闲娱乐的方式。学电脑能够快速入门是每个新手梦寐以求的事情，但是不是每个人都能快速入门的。但是如果定制好合理计划，循序渐进，就会收到非常好的效果。
电脑的组成
一个完整的电脑由软件和硬件组成。硬件主要包括我们常见的鼠标，键盘，显示器，主机和各种储存介质，电脑的硬件如同人的躯干和四肢；而软件如同人的大脑和神经系统，软件在硬件的基础上才能工作。
基础入门
启动电脑
电脑启动就是我们常说的“开机”，也是启动操作系统的过程。开机具有一定的顺序：
1、打开显示器
2、打开主机
3、开机自检
4、启动成功
通过上述步骤启动电脑，叫做冷启动，是常规的开机步骤。此外，在特殊情况下，我们还可以通过下面两种方式启动电脑。
热启动：是指电脑处于开机的状态下，通过【开始】菜单中的【重新启动|】命令对电脑进行重新启动。
复位启动：当电脑在运行过程中出现异常而不能运行，且采用热启动失效时，可以采用复位启动方式重启电脑，方法是按下主机箱上的【复位】按钮即可。
关闭电脑
使用完电脑后，需要将其关闭。电脑的关机顺序与开机顺序正好相反。即先关主机电源，然后逐一关闭外部设备的电源。遵循正确的开关机顺序可延长电脑的使用寿命。
正确的关机方法为：在系统桌面上单击【开始】按钮，在弹出的【开始】菜单中单击【关机】按钮，电脑将停止所有程序并退出操作系统，接着系统将自动断开主机电源，然后再依次关闭显示器、音箱等外接设备即可。
如何使用键盘
键盘是用于操作计算机设备运行的一种指令和数据输入装置，也指经过系统安排操作一台机器或设备的一组功能键（如打字机、电脑键盘）。
电脑键盘由功能键区、主键区、编辑键区，数字键区和小键盘区5个区组成。其中常用操作打字是在主键区完成的。
键盘是最常用也是最主要的输入设备，通过键盘可以将英文字母、汉字、数字、标点符号等输入到计算机中，从而向计算机发出命令、输入数据等。
如何使用鼠标
鼠标，是计算机的一种外接输入设备，也是计算机显示系统纵横坐标定位的指示器，因形似老鼠而得名（港台作滑鼠）。其标准的称呼应该是“鼠标器”，英文名“Mouse”。鼠标的使用是为了使计算机的操作更加简便快捷，来代替键盘那繁琐的指令。
一般的鼠标上有左键，右键和滑轮三个部分。
计算机的储存介质
计算机的储存介质有：硬盘、U盘、光盘和软盘等。
硬盘
电脑硬盘是计算机最主要的存储设备，硬盘一般分为固态硬盘（SSD）和机械硬盘（HDD）两种。固态硬盘读写速度更快，但存储容量较小，机械硬盘存储容量较大但同容量大小，固态硬盘价格也更昂贵。
U盘
U盘是USB(USB flash disk)盘的简称，据谐音也称“优盘”。U盘是闪存的一种，故有时也称作闪盘。U盘与硬盘的最大不同是，它不需物理驱动器，即插即用，且其存储容量远超过软盘，极便于携带。
软件操作
电脑软件（Computer Software）是指计算机系统中的程序及其文档。一般来讲软件被划分为系统软件、应用软件，系统软件为计算机使用提供最基本的功能，可分为操作系统和支撑软件，其中操作系统是最基本的软件，常见的操作系统包括为微软的Windows系统。
软件的基础操作
软件的使用包括软件的下载、安装和卸载：
软件的下载
1、浏览器下载
2、软件官网下载
3、电脑管家或360软件管家等下载软件（下图为360软件管家）
软件安装
第一种就是你下载下来的是.exe文件的应用程序，这种程序一般都是安装包，就是你双击之后，会进入安装界面；第二种就是不需要安装的，你下载下来的是一个压缩文件，你只需要解压就可以使用。
电脑软件安装过程中特别要逐一择安装设置（安装盘位）的选择、流氓软件选项勾选等。
软件的卸载
控制面板—程序和功能—找到要卸载的软件—右击卸载
软件的启动
电脑软件的启动方法一般有双击，右击-打开或从开始菜单单击打开
1、一般安装软件后会在桌面创建快捷方式，直接打开。
2、若桌面没有快捷方式，可以在电脑左下角的“开始”—“程序”里面打开。
3、若“程序”里面也没有，可以打开软件的安装位置打开。
说明：第三种方法是按默认的安装路径找到的软件安装文件夹打开程序的，实际情况可以根据软件的具体安装路径选择打开。
应用软件的操作
文件操作包括如何操作打开，关闭、删除、移动、重命名和编辑文件
文件打开
文件打开方式见“如何启动软件”部分
常见不同后缀、格式文件打开方法：

文件管理基础知识
硬盘分区
电脑中的文件都存放在硬盘中，而新买回来的硬盘相当于一张白纸 ，为了能够更好地使用它，需要在，白纸上划分出若干小块。然后再打上格子。硬盘分区就是这个道理，在安装操作系统之前，需要进行硬盘分区和格式化，然后才能投入使用。对硬盘进行分区后，各个分区独立使用，互不影响。在操作系统中每个分区都用一个盘符表示，如本地磁盘（C）、本地磁盘（D）等。
存储路径
文件的存储路径，就是文件在电脑硬盘中的存储位置，由硬盘分区、文件夹和子文件夹构成。其中硬盘分区的盘符为路径的第一项，是第一级目录，也叫做根目录，后面紧跟冒号和斜线（：/），文件夹和子文件夹中间则以斜线（/）隔开。
如何使用浏览器
主要介绍如何使用浏览器（以及搜索引擎）查找资料（以今日头条为例）。
1、首先在浏览器中搜索引擎输入今日头条，然后点击推送的今日头条进入官方页面：
2、然后就进入搜索引擎所在网页，这样才能进行搜索：
3、之后在搜索栏中输入搜索内容，可以是词语、短语也可以是句子：
4、最后点击搜索框后方的放大镜进行搜索：
5、然后就可以得到想要的信息了：
电脑的日常维护
日常注意事项
电脑的五大要害：静电、灰尘、水、震荡、病毒是电脑的五大要害
1、防静电：防止静电损坏电脑各部分电子原件，处理办法是将电脑机箱外壳接地，尽量使用三脚电源插头。
2、防尘：防止灰尘进入电脑机箱内，使用时保持环境清洁，并定期清理电脑主机内的灰尘。
3、防水：防止液体进入电脑的任何部分，保持室内通风。不要将电脑放在湿度较大的房间使用。
4、防震：在使用的过程要防止对电脑的震荡，应将电脑平稳放置在电脑桌上，以防不小心摔落等
5、防病毒：病毒是电脑的一大要害，在日常使用中要防止病毒的进入，需要给电脑安装防病毒软件，并经常更新病毒库，经常给电脑杀毒。
显示器维护
液晶显示器最大的禁忌在于触摸液晶面板。液晶面板表面有专门的涂层，这层涂层可以防止反光，增加观看效果。而很多用户不知道这点，总是习惯于用手去摸液晶屏幕，殊不知人手上有一定的腐蚀性油脂，会轻微的腐蚀面板的涂层，时间长了会造成面板永久性的损害。这种被损坏的面板在使用中会有斑驳陆离的感觉。另外，有些人喜欢用手去压面板，觉得很有意思。这绝对是个恶劣的习惯，这样做会导致坏点和暗斑，这可是永久性的损害，绝不可修复的！
主机维护
在电脑运行过程中，机器的各种设备不要随便移动，不要插拔各种接口卡，也不要装卸外部设备和主机之间的信号电缆。如果需要作上述改动的话，则必须在关机且断开电源线的情况下进行。
不要频繁地开关机器。关机后立即加电会使电源装置产生突发的大冲击电流，造成电源装置中的器件被损坏，也有可能造成硬盘驱动突然加速，使盘片被磁头划伤。因此，这里我们建议如果要重新启动机器，则应该在关闭机器后等待10秒钟以上。在一般情况下不要擅自打开机箱，如果机器出现异常情况，应该及时上报。
数据存放在不同分区，减少磁头对某一扇区的经常读写，导致这一扇区的损坏。 建议你使用不同的媒介定期对你的重要数据进行备份，并存放在不同的地方。一个文件可以在备份盘上放一份，可以打印一份，可以刻录成光盘。
键盘、鼠标的日常维护
（1）保保持清洁 过多的灰尘会给电路正常工作带来困难，有时造成误操作，杂质落入键位的缝隙中会卡住按键，甚至造成短路。我们在清洁键盘时，可用柔软干净的湿布来擦拭，按键缝隙间的污渍可用棉签清洁，不要用医用消毒酒精，以免对塑料部件产生不良影响。清洁键盘时一定要在关机状态下进行，湿布不宜过湿，以免键盘内部进水产生短路。
(2)不将液体洒到键盘上 一旦液体洒到键盘上，会造成接触不良、腐蚀电路造成短路等故障，损坏键盘。所以我们一般不要边喝茶边坐在电脑前,这样一不小心茶可能就洒在键盘上.
电脑病毒防护
电脑一旦感染了病毒，就会出现很多症状。导致系统性能的下降，影响用户的使用，甚至造成灾难性的后果。电脑在日常的使用过程中要定期进行病毒查杀，防患于未然。常用的电脑杀毒软件有360，金山毒霸和电脑管家等等。以金山毒霸为例介绍电脑杀毒的过程。
1、打开程序主界面
2、选择杀毒方式
3、开始杀毒。程序对磁盘内容自动进行扫描，如果检测到病毒会自动进行清除，并将结果显示在扫描栏中。
4、除此之外还可以对特点的盘进行杀毒。
