从理论和谱分析实验研究了钢琴的击弦点及击弦力度对钢琴幅度谱的影响。

Finally, the effect of striking force and striking point at string on the amplitude spectrum are discussed.

我们在后面会谈到真正的击弦运动的结构并在那时候谈及手指运动的描述。

We will talk later about the mechanics of an actual stroke and refer back to this description of finger motion at that time.

在击弦时它可以有轻微的运动，因为弦对手指的压力，但是我们不要尽力来控制这个关节。

It can move slightly during a stroke because of the pressure against the finger from the string, but we will not try to control this joint at this stage of playing the guitar.
