水晶与岩石摩擦发光的实验研究

采用直线滑动和圆周转动两种实验方法研究水晶与岩石摩擦发光规律.得到的结果是:岩石表面发光度与岩石破裂所需功率密度之和,正比于摩擦机械功率密度.摩擦机械功率密度等于滑动摩擦系数、压强和速度的乘积.当摩擦系数和速度不变时,表面发光度最大值与压强成正比;当摩擦系数和压强不变时,表面发光度与速度成正比。通过实验探讨地震发光与摩擦发光之联系。

Some Experimental Study on the Light Emission From Abrasion of a Quartz Crystal and Rocks

Introduces two experimental methods- rectilinear slide/circular motion, for the study of light emission when a quartz crystal and a rock are abraded against each other. It has been found that the sum of the surface luminosity and the mechanical power density, is directly proportional to the frictional mechanical power density (coefficient of friction multiplied by pressure and velocity). When the values of the coefficient of friction and velocity are kept constant, the surface luminosity is proportional to the pressure, and when the values of the coefficient of friction and pressure are kept constant, the surface luminosity is proportional to the velocity. These results give some clues for the exploration of the phenomena of triboluminescence on occasions of earthquakes.
