| 摘 要： | 将引力理论视为宏观衍生理论，根据固体物理中的Debye模型，引入零点能修正能量均分定理。进而利用Verlinde熵力的方法去得到修正的Friedmann方程，并将修正项解释为与时间相关的真空能量密度。

| Abstract: | Regarding gravity as an emergent phenomenon,we modify the equipartition energy theorem based on zero-point energy in Debye model of solid physcis. Then the modified Friedmann equation can be obtained with the use of Verlinde＇s scenario and the correction is interpreted as the time-dependent vacuum energy density. |
