论文摘要
基于Glauber方法中变形CSH $ _2 $ _4 $ CRYSTAL的假蛋白模型，获得了伪源性的时间相关平均值的方程式，而在与平衡状态的小偏差的情况下可以解决。使用方程的溶液，我们找到了纵向动态介电常数和松弛时间的表达式。基于理论的提议参数，计算和研究了动态介电常数的温度和频率依赖性和弛豫时间的温度依赖性。对获得的结果进行了详细的数值分析。研究了静水压力对CSH $ _2 $ po $ _4 $的动态特性的影响。
Based on the pseudospin model of the deformed CsH$_2$PO$_4$ crystal within the Glauber method, the equation for the time-dependent mean value of the pseudospin is obtained, which is solved in the case of small deviations from the equilibrium state. Using the solution of the equation, we find expressions for the longitudinal dynamic dielectric constant and relaxation time. Based on the proposed parameters of the theory, the temperature and frequency dependences of the dynamic dielectric constant and the temperature dependence of the relaxation time are calculated and investigated. A detailed numerical analysis of the obtained results was performed. The influence of hydrostatic pressure on the dynamic characteristics of CsH$_2$PO$_4$ is studied.
