The triboelectrification of two pieces of similar quality ice specimens was investigated with asymmetrically rubbing. In this case, there is an asymmetry of heating in the experiments with crossed rods, the one has the rubbed surface developing a hot spot, the other has the rubber receiving a relatively small rise in temperature. The rubbed surface as like the hot spot was negatively charged against the other rubber as ribbon. Moreover, if the rubbing continued for a long time, the polarity of charge became reversed due to a changed nature at the rubbed surface of one of the specimens caused by the rubbing. The hot spot suffers more strain than the surface of the other rubber and only the hot spot with strain was recrystallized from a single crystal to polycrystalline. In order to make a clear the effect of the strain on the triboelectrification of two kinds of specimens with isomeric properties, the one a strained ice specimen, the other a normal specimen, the experiment was carried out. As a result, the conclusion, namely, the more strained the specimen, the more the specimen got charged positively, was obtained.
