With the help of infrared spectroscopy, it is known that the linkage between dodecylamine and sodium oleate and diaspore, kaolinite, illite and pyrophyllite is fundamentally electrostatic forces, which contributes to physical adsorption. The adsorption is related with surface electric property of minerals. The effect of chemical composition of diaspores on their electrokinetics was investigated.

The first one and the eleventh one are concentrate to the tensibility of finger, the second one is famous of it"s fingering technique which is the typical fingering of Chopin, the third and six one are experience the layer of mufti voice parts, the fourth one is keenness which carries on by its speed and music the alone difficulty , the fifth one is the"black keyetude , harmonic innovate are visibly reflected at the seventh, the tenth and the eleventh one, humorousness is performance in the bass field in the eighth one, the ninth and the twelfth one are training stretching and running technique of left hand.

第一首与第十一首是针对手指的伸张技术；第二首是赋予了肖邦典型技术特征的指法；第三首与第六首是多声部织体的演奏；第四首是以其速度和音乐进行的尖锐性而独具难度；第五首是"黑键"练习曲；和声的创新手法在第七、第十以及第十一首里都有明显地体现；第八首最大的特点在于它用左手在低音区表现出谐谑式的旋律；第九首与第十二首在单纯手指技术上是分别训练左手的伸张及快速均匀的跑动。

This article will research into the performance style, ways of touching keys and the acoustics of it. Through the comparison of the Intermezzo in three periods, I will also make an intensive study of his Intermezzo, especially the late period one. I hope that this research can provide valuable reference.

Op.117这一作品是其"间奏曲"中最为著名的一部，同时也是钢琴独奏音乐会中使用较多的一首，本文将对其演奏风格、触键方法及应该表现的音响效果方面进行研究，并通过三个时期间奏曲的对比对其间奏曲，尤其是晚期间奏曲进行比较系统的研究，希望这一研究可以为这一方面提供有价值的参考。
