| 摘 要： | 在实验室条件下研究了花岗岩样品受单轴压缩破裂过程中的光和声发射效应,所得可见光谱轮廓与空气分子的光谱相似,但具有能量高于紫光的成份。除在主破裂时有大的光脉冲和声发射外,在主破裂前也记录到弱的光脉冲,它们与大的声发射率有同步现象。

| Abstract: | The effects of light and acoustic emission during the fracture of a granite subjected to uniaxial compression have been studied under laboratory conditions. The energy spectrum of emitted light was very similar to the spectrum of air atmosphere except there were some components in the ultraviolet ray. Before the major failure, some light pulses were recorded. accompanied with intensive acoustic emission. |
