1.R9、R10是反馈取样电阻，图中标示的是对的!

2.4001仅最大1.5安，电流是偏小!可换成800系列!

3.C1、C2、C7、C8越大越好!有利于滤波及电流!

4.IC2一般是337，但该图为317反用!

5.C3、C4应为0.1微法!它们是滤高频尖波及防自激用的!

6.R7、R11是负载电阻!可以如图，也可在22-96K间选用!

7.LM337如图时无法搭配!因741为正电集成而337为负电输出!

8.其实，741部分可以省略!而IC2换成337系列即可。

先用副边双绕组降压变压器输出两路27V交流,分别整流、滤波,接LM117稳压块,稳压块调整为25V输出,然后,将两路串联输出,即可得到50V稳压电源.也可采用中间凑头变压器,采用LM117和LM317分别输出+25V和-25V,+25V和-25V两端输出就是50V稳压直流电源.

3. lm317可调稳压直流电源电路图

LM317是三端可调正电压直流稳压器，输出电压范围1.25~37V，最大输出电流1.5A。

4. lm317可调稳压电源电路工作原理

317工作电压（输入、输出压差）至少需要2V，即在4.2V输入条件下，只能在2V以下输出电压时才具有稳压功能。解决方法：

1、提高输入电压，保证比输出电压大2V以上（最好3V以上）；

2、不能用317，重新寻觅“低压差”稳压块（电路）。目前最优设计大概能做到0.3V压降，因为稳压器不是导线，总是要有压降的，0.7V压差不值得惊讶。

5. lm317可调直流稳压电源电路原理图

LM317是一款输出可调的正电压线性稳压器，它的工作原理实际就是对输出电压进行实时采样，并以采样电压进行负反馈，来调节输出管的动态电阻和压降而使输出电压保持稳定。

比如，由于输入电压下降或负载电流增大而使输出电压产生下跌，这时候LM317就会通过上述的一系列动作（采样、负反馈、调整）使输出管的电阻减小，这样就使管压降也减小从而在很大程度上抵消了使输出电压下降的那些因素的影响，使输出电压保持基本稳定。

6. lm317可调稳压电源电路图课程设计报告

答：lm317可调直流稳压电路：输入电压或负载变化时，控制电路进行取样、比较、放大，然后驱动伺服电机转动，使调压器碳刷的位置改变，通过自动调整线圈匝数比，从而保持输出电压的稳定。

⒈稳压电源在通电启动时，请勿随意拆开稳压电源或拨拉稳压电源输入输出连线，以防触电或其它电气安全事故。

⒉稳压电源输入输出连线一定要布置合理，防止踩踏磨破，造成漏电事故。

正常情况下输出电压都是可调的，会不会是匹配电阻不对？或者线路有问题

尤克里里中文名称准确的叫法是“夏威夷小吉他”，而音译名称则叫做“尤克里里”，在夏威夷语中，又称之为“到来的礼物”，是一种四弦、拨弦乐器，同时也归属于吉他乐器一族。

分类

21寸

标准型，长度大约53cm，喜欢弹唱的可以选择21寸，21寸也是尤克里里的经典尺寸；

23寸

长度大约59cm，23的指弹和弹唱兼顾，箱体略大些，声音更浑厚些，觉得21小的，可以选择23尺寸，音域也更广。孩子的第一把琴推荐选择23寸的。

26寸

26相对适合指弹，特别是弹过吉他的琴友，普遍觉得21和23的小，26的箱体更大共鸣更好，对于吉他手或者演出的朋友推荐选择26寸的！

组成部分

琴头

这个部分是用来固定琴弦和安装琴弦的，主要由弦轴和弦钮两个部分组成。

弦轴是用于连接齿轮和弦钮的部位，可以固定琴弦。 弦钮是用来松弛和拉紧琴弦，可以降低或者升高琴弦的音高。尤克里里的弦钮一共有4个，左边2个，右边2个，每个弦钮分别对应一根琴弦。

琴颈

琴头与琴体的连接部分，表面镶有品丝，深色部分叫指板，指板背面为弧形。

琴枕

一般是由硬塑料或牛骨制成，它能把琴弦的振动限制在它到琴桥之间。琴枕上面有让琴弦通过的四个弦槽,琴弦由此连接到琴头的弦轴上。

琴肩

连接琴体与琴颈的部位，起到固定的作用。

品丝&品格

品丝是与琴弦垂直的金属条，能改变琴弦振动的长度而产生不同的音高。

每个品格都代表不同的音高位置，弹琴时手指一般都是按在品格上。

品格标记点

品格标记点可以让你很快地找到某一品的位置，尤克里里的品格标记点一般都是小圆点，但一些很高端的琴装饰会有华丽的图案。

琴体

琴体是固定琴颈和琴桥的箱体。弦振动时,琴体可产生共鸣，所以琴体也叫共鸣箱，正面有一个音孔。

音孔

音孔又称声孔，是指琴体上的开口，声音由此发出。

琴码

琴码是贴在面板上的木块，用睐固定琴桥和琴弦的末端。

琴桥

一般琴桥是由硬塑料或牛骨制成，来固定和限制琴弦的振动。

琴弦

尤克里里的琴弦从左到右依次为4弦、3弦、2弦、 1弦。

选购

作为初学而且是自学的人，需要的更多是自己的学习的动力及坚持。所以对于初学乐器一般选择中下价位的即可，建议以100~300价位为初学配置为宜。目前尤克里里主要有21、23、26三种尺寸，初学者选择23的较多。

木材有桃花木、沙比利、云杉木等。不同大小或者木材的其音色都会不同，初学者选择23寸的桃花木制即可。 选定了基本信息，网购的朋友注意看评价以及信誉，尽量挑选保障较为多且较为专业的卖家，注意图片是否实拍。到手前也可以去看看尤克里里的教学视频，看看自己能不能理解。现在网上视频入门是比较简单的，重要的是能不能坚持练。建议买一套基础教程， 一般购买尤克里里的时候店家也会赠送一套。 入手之后就要着手调音，最好在店家那里让他们帮你调好，当然你也得学会。

组装

1、买来后，首先检查配件是否齐全，确定齐全后再开始组装，如果有配件缺失，要联系商家补发。

2、开始组装时，先將木肖插入琴头的孔中，在周围滴加胶水加以固定。

3、将琴头扭转进入琴身上面的孔中，在指板和琴头上面滴加胶水，并冷却1 ~ 2分钟，效果更佳。

4、安装指板,安装的时候要注意,指板最后一根丝线在琴头与琴身的相交处。

5、将琴弦插入下码孔中，在末尾处打上死结，最好是同个位置上打上两个死结。使用两根长螺丝固定下码并且安装下琴枕。

6、从左到右安装琴弦，第一根琴弦最细，第四根琴弦最粗。

7、安装调弦钮，都以螺丝帽在下的方式安装，找到相应的位置，使用八个小螺丝固定。

8、以底垫向上的方式安装，滴加一点胶水安装上琴枕。

9、使琴弦安装在螺弦钮中，中间两根琴弦分别在上面的调弦钮孔中，左右两边琴弦分别在下面的调弦钮孔中。

10、穿入一部分琴弦，稍微松懈，一只手按压,外一只手旋转螺弦钮，也可以适当绕几圈。调整好琴弦修正好音后, 上下多余的弦头都可以剪掉。

调音

1、最常见的两种尤克里里（标准型和高音型）的四根弦对应的音名分别是低音G（低于中音C的G音 ）、中音C、E、A。

2、为了准确说明每个调弦旋钮对应哪根弦，拧转旋钮可以调整琴弦的音高，调弦时具体的旋转方向因琴而异。同一侧的调弦旋钮的拧转方向是一致的。调紧琴弦音调升高；调松琴弦音调降低。琴弦调得过紧，不仅可能弄坏琴，琴弦也会绷断。左侧下面的旋钮调G弦，上面的调C弦，右侧上面的旋钮调E弦，下面的调A弦。

3、按琴弦与你之间的距离按从远到近编号，如果右手弹琴，第一弦是A弦，第二弦是E弦，第三弦是C弦，第四弦是G弦。

4、品格按从调弦钮到音孔的方向依次编号，离调弦钮最近那一格的为第1品。按住某一弦至某一格，弹响，弦音升高。

5、最简单的方法是将琴弦的音高调到与另一乐器的音高一致，供参照调音的工具有很多种，如钢琴、在线调音器、电子校音器、调音管。你可以先定其中某一根弦的音，再根据定好的弦调整其他的几根弦；也可以用调音设备逐一定每根弦的音。

6、琴弦对准钢琴相应的琴键，一边弹琴一边调整，拧转旋钮直到琴弦与琴键音高一致。

7、可选用圆形的半音阶调音器、尤克里里专用的调音笛（很像小排笛）。一边吹笛一边弹相应的弦，拧转调弦钮，直到琴弦音高与调音笛一致。

8、敲击音叉依次调整每根弦的音高，直到与音叉的音高相符。先用这个音叉定其中的一条弦，然后再以此弦为基准来定其他的弦。

9、电子校音器有两种，一种发出标准音高，需要你调整琴弦直至与这个音相符；另一种能分析琴弦的音高，是太高还是太低。

10、定G弦：定准G弦（与你的距离最近的弦）。

11、弹A音：按G弦第二格，弹响就是A音，与最远的那根弦（A弦）空弦的音高是一样的。

12、定A弦：将A弦空弦的音高调成与G弦上找到的A音一致，即定准A弦。

13、用E弦弹G音：按E弦第三格，弹响就是G音，应与G弦空弦音高一致。如果不一致，那很有可能是E弦不准。

14、定E弦：调整E弦直至按E弦第三格弹出与G弦空弦一致的音高。

15、用C弦弹E音：按C弦第四格，弹响，应为E音。16、定C弦：调C弦直到用C弦第四格弹出的音高与E弦空弦音高一致。

16、定C弦：调C弦直到用C弦第四格弹出的音高与E弦空弦音高一致。

乐理

空弦

尤克里里从上边数第一根简谱是6，唱名是A。第二根简谱是3，唱名是E。第三根简谱是1，唱名是C，它也是最粗的一根。第四根简谱是5，唱名是G。从右到左也就是从第一根到第四根依次为6、3、1、5。

技巧

和弦技巧

手指尽量跟指板是垂直的状态，就是让你的手指站起来，不会让你的手指按到或是碰触到隔壁的弦或是其他的弦导致声音没有弹出来或是被闷掉。

和弦的第一格使用食指，第二格用中指，第三格使用无名指，如果一个和弦使用到了三个格数就会尽量在第一格使用食指，第二格使用中指，第三格使用无名指。

按好和弦后先别着急着弹刷出节奏，先一弦一弦拨拨看是否都可以有干净的声音，否则练习久了可能还是没办法弹出好听的声音。

转换和弦

如果有不需要换指按的和弦位置就不需要换，如Am和弦跟F和弦，手指在第四弦的第二格斗是使用中指，所以这两个和弦转换就不需要浪费时间再去改变中指的位置。

转换和弦时接近的指型保持原本按好的指型

如Em和弦和G7和弦也可以看到食指和中指的指型并没有改变，只是移动到不同位置，这时就可以保持一样的指型去按，习惯之后就可以省下不必浪费的动作了。

基本指法

换和弦之前记得放手手指，如果手指过于紧张或是之前用力过猛，当然就会不灵活了，所以换和弦前记得要先放松手指，且和弦用力按久了也会手指变僵硬。

左手用力要适当，左手在按和弦时自己要掌握好恰当的力度，既要让和弦能被弹响，又不能过于用力。不然可能会对长时间的演奏或者练习的耐力不利，而且也可能对演奏时整个乐曲流畅度有一定的影响。

初学者朋友一开始对左手力道的掌握肯定比较难，这就需要在以后的练习中有意识的去注意这个问题。

练习方法

对于新手来说，可以通过练习爬格子提高手指的灵活度，增加手指的力度，提升手指的跨度。

可以从第一根琴弦第一格开始，一个手指一格地爬行，一弦弹完就换到二弦，二弦弹完再换到三弦，以此类推。

注意大拇指的位置，和食指相对些；左手手指指尖摁琴弦，摁的位置靠近品格下方的品丝。

练习爬格子时要保证每一个弹出来的音是清晰，结实的，尽量避免弹出杂音、哑音。

拨弦技巧

右手拨弦

第一种也是最简单的方式是拇指拨弦，四根琴弦都只使用拇指下拨。这种方式上手容易音色统一，拇指向下拨很适合弹奏琶音，但是无法演奏快速的拨弦曲子。

第二种方法是重点推荐的尤克里里传统演奏使用的二指法，就是使用拇指和食指。拇指关节保持伸直，与琴弦大约呈45度角。为了保持拇指的角度，需要将手腕向外拱起。食指第一、第二关节弯曲起来，用指尖正面轻轻勾住1弦下方。中指和无名指伸直支撑在面板上。手腕处于4弦上方，不可放松下沉。 其中拇指负责3、4弦的拨弦：活动拇指的第二指关节，斜下向外拨晌琴弦。食指负责1、2弦的拨弦：活动食指的第二指关节，用指尖勾晌琴弦。拨弦时保持剩下的手指支撑固定在琴面上，用最小的动作拨晌琴弦即可。

三指法就是用三根手指（食指、中指、无名指）轮流弹奏，听起来很舒服，也很抒情，有些歌曲弹奏起来就像是在述说着故事一般。

三指法弹奏方法：左手的大拇指与指板相互垂直，其余的手指随意放在指板上，右手的大拇指则要用来拨弦。

其中大拇指向下波动第3、4弦，食指向上波动第2弦，中指也是向上波动，但中指波动第1弦。

大拇指和食指一起匀速地从第4弦向下扫过四根琴弦，当然也可以向上扫弦，注意扫弦的时候不要太用力，否则会把琴弦弄断。

练习流程

由简到繁

不要选一些没必要的高难度练习来折磨自己，那些超越你能力范围的技巧只会让你感到沮丧和无助，最好的办法就是从那些你喜欢并且熟悉的简单歌曲开始练习，选一些和弦变化尽可能少的，节奏型也要尽量简单，同时你可以轻松记住那些歌词的曲子，比如就像生日歌那样的歌曲。

熟记指法

如果在你唱歌的同时你才回想B7和弦该怎么按,那么你想表演好一首歌是几乎不可能的。 你必须达到熟练基本和弦的水平，能在不同的和弦之间不费力地自由转换，甚至不用思考下一步该怎么走， 你的手指已经自动放在了正确的位置。这样的话你就能将注意力全部集中在演唱上了。

跟着练习

如果你想对时值和节奏有更好的把握，那么你一定要跟着节拍器一起练习。 当然起初的时候这样可能会让你感觉很受限制，但是节拍器能帮助你成为一名更稳定的乐手。每天只要花十分钟的时间伴着节拍器练习一个简单的节奏型，几周之后你就能感觉到你的时值和节奏有了明显的进步。

弹唱结合

就像那些钢琴手用两只手同时弹奏不同的节奏，或者像鼓铜时独立活动四肢一样,你需要将你的弹奏和

演唱节奏融合起来，这样能让它们听上去很和谐，弹和唱是不可分割的两件事。

其他技巧

扫弦

手指与琴弦接触面积，不能太厚！拨弦时候同学们尚且知道手指指尖轻轻拨动琴弦，那么扫弦无非就是手指快速接触琴弦，自然也要像蜻蜓点水一般。初学扫弦，手指与琴弦接触面积小一些，声音清脆悦耳。扫弦用指甲尖，扫时与弦成一定的角度，不要完全垂直。想象指甲就像拨片，练的时候注意去感觉舒服的角度，角度对了的时候一定是很顺畅的，快、干脆，但不要用蛮力。

（1）拇指琶音多用于舒缓，富有情感的歌曲伴奏；

（2）用拇指下扫食指上扫，大部分流行歌曲都能用此手法进行扫弦伴奏；

（3）食指扫弦，下扫回扫都用食指进行操作，方便衍生出例如切音这样的节奏变化形式。

手臂带动手腕，手腕带动手指！大家想象一下自己熟悉的两个动作，洗手之后把水从手上甩下来的动作、甩体温计的动作。如果你扫弦时手臂手腕僵硬，那自然是不会好听的。一开始练习，动作尽量夸张一些。尽量习惯用手腕的转动去带动扫弦动作，而不是凭手肘的力量，是一种将手轻松甩来甩去的感觉，这样后面提升扫弦速度的时候才会轻松。

传统尤克里里也可以只用一只手指，食指或拇指，来单独完成一次上下交替。这个看自己的喜好，出来的音色有所区别，随意选择就行，自己喜欢都可以用，换着用。可以自己选一首歌配上不同的节奏试试感觉如何。

和弦分散法

不是指和弦的分解，而是强调用不同的手指弹奏乐曲或不重复地弹出其余的和弦音。这种演奏方式，一般是尤克里里学到较为熟练的程度,且所弹旋律具备流畅抒情特点时，而被广泛采用。

食指敲击法

是用指甲敲弹琴弦,动作不宜过大，一般以腕关节为轴，松弛而自然地敲击。 需要强调食指敲击法应与琴弦垂直，同时可按上下两个方向敲弹。向上是用的指甲内侧，向下则是用的指甲背。

姿势

琴头朝向身体的左侧，微微向上倾斜。琴体置于胸煎正煎方，有手用除了拇指以处的四根手指指尖从琴体煎段的下册托住琴体。前臂夹住琴体正面尾部，左手使用手掌的侧边托住琴头，拇指从琴颈.上方轻轻握住琴颈，使虎口贴住琴颈背面，手腕保持伸直状态。

坐势

立势

演奏姿势

手腕微微凸起，手指呈半握拳状，各个关节向外凸起，拇指在前，其余手指在后，拇指指尖侧面朝下外方拨弦，发力点在手指根部。其余手指指尖正面向上方勾弦，发力点也在手指根部。

保养

尤克里里是一种乐器，平时使用过程中要注意爱护，并做好尤克里里的保养工作。许多人不知道怎么爱护自己的尤克里里，不知道怎么保养，导致乐器使用寿命大大缩短，下面为大家介绍尤克里里的保养方法。

存放时

不用的时候最好把尤克里里放进琴箱里面，然后水平放置，且琴箱上不可放置重物。湿度要保持在40%到60%，温度在24°C左右是对尤克里里较为舒适安全的环境。如果长期不弹就要松下琴弦，尽量平放,不要靠墙，放在不容易摔的地方。

使用后

弹完琴可以用擦琴布护理下尤克里里的指板及琴身，有灰尘不能用湿纸巾去擦，要用细腻柔软的布，否则琴弦容易生锈。

护理时

需要用到指板油也叫柠檬油，均均的在指板上可以防止指板开裂，按着更舒适，还有淡淡的柠檬清香。可用擦琴布轻柔擦干净琴弦上残留的油脂，可以用酒精等其它对琴身有损坏的清洁剂。天气潮湿的时候，可以将干燥剂适量地放在琴箱里，使琴身保持在适当干燥的环境里。

尤克里里保养注意事项

1、多弹，让尤克里里各部分充分震动,弹琴是对琴最好的保护，不要让尤克里里在角落里吃灰。

2、平时不弹琴的时候，要把琴放包包里，不要放在地面或者靠墙,放置时需平整放置，避免重物压着尤克里里。

3、中低档尤克里里要买加厚棉的琴包，高档尤克里里则要配备琴盒，这样便于尤克里里的安全存放。

4、温度、湿度的突然变化会对尤克里里造成伤害。平时要避免尤克里里在阳光下照射(夏天在外面弹琴时，尽可能选择阴凉处)，不要靠近暖气。如果空气过分潮湿可在琴盒内放一些纤燥剂。

5、不要让琴沾到水，不要一洗手， 手还没干就碰琴，手上有汗也要擦干。

6、对于高档尤克里里，千不要放在桌面或者地板上，注意弹奏使用时避免和拉链、纽扣之间碰撞造成损伤。
