一、气流作用于笛塞的压力分布关于气流作用于笛塞(竹笛)的压力的性质和分布是通过实验测得的。现将实验及实验的结果总结如下:实验用的竹笛是一支内孔直径约等于15mm 的 F 调普通竹笛。首先在笛塞中心正下方3.5mm 处钻一个直径等于1.5mm 的小孔 B_2(见图一),在竹笛顶端贴上试验用“笛 First, the pressure distribution of the air flow on the flute The nature and distribution of the pressure on the air flow acting on the flute (bamboo flute) is experimentally measured. The experimental and experimental results are summarized as follows: experimental bamboo flute is a hole diameter equal to about 15mm F tone ordinary bamboo flute. First of all, a hole B_2 equal to 1.5mm in diameter is drilled 3.5mm just below the center of the fluke (see Figure 1). The flute
