摘　　要：利用三阶WKB近似方法,计算了Horave引力理论中Park黑洞的有质量标量场扰动下的似正规模频率.当其它参数确定时,随着标量场质量的增加,似正规模频率的实部也增加,而虚部的绝对值则减小.虚部和实部是随着标量场的质量做线性变化的.这些结论将有助于我们加深理解Horave引力理论.Using the third-order WKB approximation.We evaluate the quasinormal frequencies of massive scalar field perturbation around Park black in Horava gravity.We find that as the scalar field mass increase when the other parameters are fixed,so do the real parts and the magnitudes of the imaginary parts of the quasinormals frequencies decrease.The imaginary parts are almost linearly related to the real parts.These information will help us understand more about the Horava gravity.
