在笛子的制造过程中,确定孔位是一道非常关键的工序。各孔位置可以用计算画孔法或尺板画孔法来确定。前者繁琐复杂,不易掌握;而后者简单方便,工作效率很高,较为普遍采用。但是后种方法却存在着难以克服的缺点。因此,研究与讨论此画法中的一些问题,无疑对提高产品质量有其现实意义。大家知道,制作笛子的用料是天然生长的竹材,其各部尺寸及形状很不规格,我们不可能用无数个不同规格的尺板来对付千变万化的竹料。一些笛子制作者在生产实践中发现内径与基音管长存在着一定的调整关系:在一定范围内,内径大,基音管长应缩短;内径小,基音管长应放长;两者的调整关系约为1∶4。因此,一些有经验的师傅常常根据竹料内径粗细情况采用移动孔位的
In the flute manufacturing process, determining the hole is a critical process. The location of each hole can be calculated using the hole method or draw-hole method to determine. The former complicated, not easy to grasp; the latter is simple and convenient, high efficiency, more commonly used. However, the latter method has its own drawbacks that can not be overcome. Therefore, researching and discussing some problems in this painting method undoubtedly has its practical significance for improving product quality. As we all know, the materials used to make the flutes are naturally grown bamboo. The size and shape of each part of the flute are very irregular. We can not deal with the ever-changing bamboo material with numerous plates of different sizes. Some producers of flutes found that there is a certain adjustment relationship between the inner diameter and the pitch tube length in production practice: in a certain range, the inner diameter is large, the pitch tube length should be shortened, the inner diameter is small, the pitch tube length should be lengthened, and the adjustment relationship between the two About 1: 4. Therefore, some experienced masters often according to the thickness of the bamboo material used to move the hole size
