手风琴漏气是左手经常出现的一个普遍的毛病,它不但影响手风琴的音色、音量,而且伴有杂音,因此常常令演奏者大伤脑筋。解决手风琴漏气时,首先应该清楚哪些地方可能漏气,然后细心检查,准确判定后用相应的办法处理。

造成手风琴漏气的原因是多种多样的,找到“病因”然后才可对症下药。

1。 琴箱开缝: 琴箱开缝有两个原因,一是制作琴箱的木材没有干燥好,当气候条件发生变化时,琴箱便会出现缝隙而漏气。二是在生产中不细心留下缝隙。先来判断缝隙在什么地方,拆下手风琴右侧的装饰盖和左侧的贝司机,用力推拉凤箱同时将脸贴近这两侧并上下来回移动,以确定漏气的部位,然后用稍稠的白胶将该处缝隙堵上,待胶干后试验一下是否漏气即可安装好使用了。

2。 风箱故障: 用同样的办法判断风箱四周什么地方漏气,然后拆下风箱观察该处垫的皮圈是否卷曲、有杂物,如有,清理干净弄平皮垫把风箱装好。但有时也许是皮囵老化破损,这就需要更换新皮臼,如果手头没有可临时用合适的吹塑纸代替。年久的手风琴,把风箱迎光照一照,看看风箱上的羊皮折角是否损坏漏气,如果有孔则需更换羊皮或用白胶布粘上凑合一时。

3。 附件松动: 手风琴背带和风箱扣带的固定螺丝是穿过外壳从里用螺母拧紧的,这些螺丝松动也会造成手风琴漏气。先用上面的办法判断是哪个部位漏气,然后把这个螺丝拆下,往穿孔里塞一些蜡原样装好即可。如果螺丝穿孔太松,可用木材把穿孔粘死重新钻孔。同样的做法可以解决风箱销钉松动漏气。

4。 音簧盖板: 取下手风琴装饰盖和贝司机,可以看到许多粘有羊皮的长方形的金属板,这就是音簧盖板。它不正、不平或附有杂物都会造成漏气,调整音簧盖板一定要细心,一边前后左右仔细观察,一边用尖嘴钳子一点点的校正。排气孔盖也会出现同样的问题,解决的办法是一样的。有时盖板上的拉簧会脱落或无力,这就需要重新装好或调换弹簧。

5。 簧盒、簧片: 卸下风箱后,能看到许多粘有簧片的簧盒。如果簧盒变形漏气,可将簧盒拆下来,在下面合适位置垫块呢子,再把簧盒装上去拧紧。使用过久的手风琴音簧上的皮子可能会卷曲、脱落,失去挡风作用而造成漏气,应该换上好的音皮子。另外把每个簧片座的四周用蜡封死,防止漏气。

另外,左手贝司按键反应迟钝这一现象也非常普遍。而且往往在按键时还会伴有机械摩擦声。这个问题一般是贝司按钮连杆变形所致。导致这个问题的发生有两个原因。第一,制造方面的原因。在制造过程中调整好按钮后经过一段时间按钮连杆金属回弹变形。第二,在我们拉琴时左手往往有比较困难的地方如大跳、手小的人拉大于十度的双音或和弦。遇到这些地方我们有些演奏者在练习大跳时往往不注意在大跳前先将手掌位置调整到接近将要大跳至那个键钮的位置附近,然后再去按那个键钮。而是先用手指勾住那个键钮将手掌带到位后再按键。因为贝司键的金属连杆比较细,这样反复练习多次容易造成机件变形的加速从而导致按键反应迟钝。希望有这种演奏习惯的'演奏者能改变一下,也希望进行教学的老师们能注意一下自己的学生是否有这样的问题。一旦出现这种机械故障只能请专业人员进行修理,因为调整按钮连杆是需要使用专用工具来进行的,甚至需要拆下一部分按钮来修整,否则可能会是修好了这个坏了那个。

Directions:

Restrictions on the use of plastic bags have not been so successful in some regions. “White Pollution” is still going on. Write a letter to the editor(s of your local newspaper to

1 give your opinions briefly, and

2 make two or three suggestions.

Dear Editor,

I have been reading your newspaper for many years with a great enthusiasm and interest. It is my honor to write you this letter to give my views on the issue of “White Pollution”. It is my view that the limitation of the use of disposable plastic bags is of utmost significance.

I would like to make the following suggestions to put an effective stop to the wide spread of “White Pollution”. Firstly, we should ban the free use of the plastic bags. Secondly, the price of plastic bags should be further raised. Thirdly, media like your newspaper should do more to encourage the public to use paper or clothing bags to replace the plastic bags.

I hope my suggestions would be of help and thank you for your attention.

Yours sincerely,

Li Ming

To Whom It May Concern,

I am a student in this university who regularly comes to the library to spend my spare time. Generally speaking, the services you offer here is quite good; however, I have some suggestions for you to adopt.

To begin with, will you please prolong the time for reading? In the daytime, most of the students are having class, so they can’t come to the library. Moreover, some of the books on shelves are out of date. If you are so kind as to provide us some books such as the latest magazines, we will be greatly honored.

I really wish to have a more comfortable library. I would like to extend my greatest appreciation if you are so kind to take my suggestions into consideration. /Thank you for your time and consideration.

Sincerely yours,

Li Ming

在手风琴的使用过程中,右手出现问题最多的是按键或键钮反应不灵敏。而左手则容易出现漏气、贝斯按键反应迟钝等问题。

先来看看右手的情况。不管是键盘式手风琴还是键钮式手风琴,进口琴大多是采用穿通条式琴键固定法。因此,不能将其中某一个键或键钮单独拿下来。只能从低音区开始一个键一个键地往下拆。也就是说如果琴的最高音键出了问题就必须将所有的琴键或键钮全部拆下来才能解决问题,在这里请大家注意,一旦出现类似情况,一定要谨慎处理尽量不要自行拆卸,否则可能造成更大的问题。因为现在与进口琴相配的配件很少,(进口琴牌号、型号太多规格不统一)元件被损坏将很难配到合适的。当按键或键钮反应不灵敏时有两种可能一是键子木头受潮变形所致,遇到这种情况应将琴放到干燥的环境中,过一段时间会自然好转的。如还不见好转最好能找专业人员解决。二是传动部件润滑不好。可打开前后面板在润滑不好的地方点上极少量的缝纫机油,一点点就够,千万不可过多。
