    The aim of this paper is to discuss the temperature distribution insidethe event horizon by applying the internal properties of the T--S metrics.We obtain the following conclusions: 1. In the case of T--S metric for odd distortion parameter δ, thereexists a gradient of temperature on a surface of x=const inside the eventhorizon. The temperature on the poles is higher than that on the equator andthe temperature difference is proportional to the rotating rate. But thedirection of the gradient of temperature inside the event horizon is justopposite to that of on the surface of a pulsar as we have already pointedout in a preceding paper. 2. We find that the temperature is an imaginary number inside theevent horizon for even δ , It is remarkable that the region inside the eventhorizon is the forbidden region for even δ. So, the imaginary temperatureis corresponding to the forbidden region of motion for the photon. Thisproblem will be investigated later. If all singularities in space--time are hidden behined the non--singularevent horizon in the course of collapse, the space--time may always berepresented by the Kerr metric, i. e., the T--S metric for δ=1, followingthe Israel--Carter theorem. However, the T--S metrics do have ring sing-ularities on the equatorial plane outside the non--singular event horizons.Therefore, the existence of the T--S metrics for δ≥2 dose not contradictthe Israel--Carter theorem because one of the premises of this theorem isnot satisfied in the T--S metrics, that is to say the imaginary temperatureinside the event horizon for even δ is possible of realization.

    在文献〔1〕中,我们用Kerr-Newman度规及VGM理论研究了旋转带电星体表面以及坍缩后星体表面的温度分布,发现在赤道与两极之间存在着一定的温差效应,这种效应引起了许多物理现象的发生。本文将进一步用T—S度规的内部性质,探讨视界内部的温度分布,我们得出结论:对于畸变参数δ为奇数的T—S度规场,在视界内部区域的一定曲面x上,两极温度高于赤道温度,对于较大的转动效应,将存在着较大的温差,而且这种温度梯度方向恰与文献〔1〕中所讨论的脉冲星表面的温度梯度方向相反,前者是赤道温度低于两极温度;后者是赤道温度高于两极温度。当δ为偶数时,视界内部出现虚温度,但是根据T—S度规理论,对于偶数δ视界内部为禁区,于是虚温度对应着光子运动的禁区。

    The derivation of the acoustic wave equation which is valid for piezoelectric semiconductor crystals of any symmetry and for any acoustic propagating direction is presented. Three mechanisms contributing to Brillouin scattering in high resistivity ZnO crystal are analysed. They are the elasto-optic effect, rotational contribution of shear wave and the electro-optic effect induced by the aocompaning potential. Thermal Brillouin scattering in ZnO crystal is performed. All of five independent elastic constants of ZnO crystal in high frequency range at room temperature are measured and the values are smaller than those reported in lower frequency by about 4.5%. Four photoelastio coefficient relations are given and the curve of the reciprocal velocity of quasi-longitudinal acoustic wave in x-z plane 10 depicted.
