Slepian函数为联合时频定位优化问题提供了一种解决方案。在这里，通过使用一个广义优化准则来扩展这个概念，该准则有利于能量集中在一个区间，而不利于能量集中在另一个区间，导致了“增广的”Slepian函数。为了说明这些广义Slepian函数所显示的最有趣的性质，我们给出了数学基础和实例。本文还讨论了这种新的能量集中判据的相关性以及它的一些应用。

英文摘要：
Slepian functions provide a solution to the optimization problem of joint time-frequency localization. Here, this concept is extended by using a generalized optimization criterion that favors energy concentration in one interval while penalizing energy in another interval, leading to the "augmented" Slepian functions. Mathematical foundations together with examples are presented in order to illustrate the most interesting properties that these generalized Slepian functions show. Also the relevance of this novel energy-concentration criterion is discussed along with some of its applications.
