<h2>1. 奔驰gla的空调怎么冷热切换</h2>1、上车后，启动发动机，然后热车30秒。2、然后慢行5分钟，一方面是为了充分热车，另一方面5分钟也足够通过外循环把车内的空气置换一新了，另外还可以等待水温上升到正常状态。3、然后开启内循环，把空调调整为暖风模式，把温度设置到自己的舒适区域，比如22-24℃的样子。4、由于暖风是通过水温加热空气行成的，空调压缩机是不参与工作的，所以开不开A/C都行，不开可能稍微节省点燃油吧。不过如果前档起雾，还是需要开启A/C来除雾，另外开启A/C吹出来的风会比较舒适，所以看个人取舍了，开不开都行。5、最后调节风量大小，出风口方向就好了。<h2>2. 奔驰gla空调怎么开冷风</h2>奔驰gla使用汽车空调的制冷功能，首先要按下ac按钮，然后将温度调低，最后选择合适的风量就可以了。如果不按下ac按钮，那汽车空调是不会制冷的，ac按钮是汽车空调的制冷开关。汽车空调ac是压缩机的开关，简单来说，就是我们所说的：送冷风。汽车空调不仅仅只有压缩机，还有冷凝器、蒸发器、膨胀阀等。不过，压缩机是制冷系统最主要部件之一，起着压缩和输送制冷剂蒸汽的作用。既然这样，汽车开冷风肯定需要开ac开关，要不然空调系统只是鼓风机在工作，输送的只是正常温度空气。在炎热的夏天，当打开ac键时，需要把温度调节调到蓝色位置，自动空调可以设置一个温度，然后按下auto键，自动空调会自动调整车内温度。<h2>3. 奔驰gla的空调怎么冷热切换啊</h2>1、首先发动车子。2、等待水温升高，因为暖风空调是靠汽车发动机热量制热的。3、水温上升后，按下空调开关，不要按A/C键。4、然后向红色方向扭动开关，调整暖风温度大小。扩展资料：冬季空调使用：AC键是空调压缩机的开关，夏天用空调，一定要开AC键，即打开冷风；而暖风只是利用汽车内部的热循环，根本不需要启动空调压缩机，所以，开暖风只需要调节空调按钮，不用打开AC开关。在寒冷的季节，我们需要快速提升车内温度。当汽车启动时发动机开始预热，等发动机温度指针指到中间位置后，先打开暖风空调，同时把空气循环设置为外循环，让车内的冷空气排出车外，等待2至3分钟后，再将空气循环设置为内循环即可。如遇雨雪天气，车内外温度相差比较大时，前挡风玻璃很容易出现雾气，这个时候我们只需要将暖风的出风方向调整到吹前挡风玻璃的档位，几分钟就可以去除雾气。<h2>4. 奔驰gla200空调怎么调</h2>找到空调面板上的AUTO键，按一下空调就关闭了，如果AUTO按钮的灯光亮着的，表示空调处于工作状态，如果AUTO按钮灯光没亮，代表空调处于关闭状态。汽车ac开关是汽车空调的压缩机开关，这个开关主要作用是制冷，在夏季空调制冷就要打开A/C开关。<h2>5. 奔驰gla的空调怎么冷热切换视频</h2>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。如果还不太懂的朋友，可以看看古筝简谱入门课程，介绍的非常详细：https://www.bilibili.com/video/BV1xE411x7Wh/?spm_id_from=333.337.search-card.all.click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。下图是古筝指法符号对照表，在看古筝简谱的时候可以用到。古筝的指法教程视频：初学古筝的指法口诀：https://www.bilibili.com/video/BV1Et411v7pq/?spm_id_from=333.337.search-card.all.click勾、托、抹、托指法：https://www.bilibili.com/video/BV1JT4y1N7nx/?spm_id_from=333.337.search-card.all.click古筝指法抹、打：https://www.bilibili.com/video/BV1Di4y1174c/?spm_id_from=333.337.search-card.all.click古筝指法大撮：https://www.bilibili.com/video/BV1Mi4y127Tt/?spm_id_from=333.337.search-card.all.click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。
