从密度泛函的观点讨论了非均匀电子系统的线性密度响应。我们推导出一个局域密度近似的频率依赖的交换关联势，这是比较在以前的工作中使用的“绝热”的表达式。
The linear density response of inhomogeneous electronic systems is discussed from a density-functional point of view. We derive a local density approximation for the frequency-dependent exchange-correlation potential which is compared with the ‘‘adiabatic’’expression used in former work.
