音孔

The sound character of Hulusi are grace, amiable, a little bit rhonchus , be good at expressing soft and exquisite emotion, be covered with blear and beautiful feeling.

它由葫芦、主管、簧片、附管组成，主管开有七个音孔，音域为3 5 6 7 1 2 3 5 6，附管持续发一个音。

Catalpa wood is used for the base, and there are two holes, one big and on small (called the "phoenix pool" and "dragon pond", respectively) to emit the sound.

底板用梓木制成，开有两个一大一小的出音孔，称"凤沼"、"龙池"。

The location of sound hole has slight effect on the pitch.

四、音孔位置与对音高亦有些微影响，在相同组合面积的条件下，开放与气窗同侧或相邻的音孔，会产生较低的频率。

Then another secondary sound hole is requested to set for the rear vent of the unidirectional microphone to receive sound.

另需一个副音孔，供单指向麦克风的后气孔收音用

The point is very important for a normal tone , which is that you should keep breath of your sound hole, otherwise, the sound you blow is not exact and it was harsh for audience.

按孔部位 part of press hole 要吹出一个正常的音，有一点是必需做到的，凡要求关闭的音孔是不能漏气的，一丝都不能漏，否则，发出的音则不准确，让人感觉刺耳不实在。

In order to improve the discrepancy of Ocarina, we used air window of whistle, air chamber of syringe together with the sound holes of Ocarina in making a sound adjustable Ocarina. The frequency spectrum was analyzed with computer sound fixing and ranging software and statistical software was employed to analyze the effects on pitch of area of sound hole and cubic of air chamber.

本研究为改良陶笛的缺失，利用哨子的气窗、针筒的气腔与陶笛的配孔式音孔结合，自创一种可调音的陶笛，并以电脑测音软体分析其频谱，利用统计分析其音孔面积与气腔体积对音高的影响。

He went on to explain that after the top is rough thicknessed and the rosette is installed he then "calibrates" it: he selectively removes material from its undersurface, taking cues from its feel, from its translucency to light, and from its resilience.

他继续解释在面板初步的打薄厚度和黏好音孔镶工之后，他才开始作"面板厚度校正"：根据手指的触感，透光度和面板弹性，有选择性的打薄面板背面。

In this study, the author explored the factors that affect the pitch of Ocarina by experiment plan, the air window, air chamber and holes and their effects on pitch, and analyze the difference of hole arrangements of Ocarina in actual and theoretical musical scale.

本研究主要在探讨影响陶笛音高的因素，经由实验计画的进行，来了解气窗、气腔与音孔对音高的影响，以及分析配孔式陶笛在实际与理论音阶上有否差异？

Left ring finger, middle finger, index finger, respectively, by section I of the stomach opening and closing means, fourth, fifth, sixth音孔Hole, thumb at the bottom of the seventh音孔Hole.

左手无名指、中指、食指用第一节指肚分别开闭，第四、第五、第六音孔，拇指开开位于主管前下方的第七音孔。

This transverse bamboo flute has a blowing hole, a stop hole and six finger holes.

吹孔气鸣乐器，笛体上升有吹孔和膜孔各1个，按音孔6个

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
