说明：  压缩感知，也被称为压缩采样或稀疏采样，是一种寻找欠定线性系统的稀疏解的技术。压缩感知被应用于电子工程尤其是信号处理中，用于获取和重构稀疏或可压缩的信号。
(Compressed sensing, also known as compressed sampling or sparse sampling, is a technique for finding sparse solutions of underdetermined linear systems. Compressed sensing is used in electronic engineering, especially in signal processing, to obtain and reconstruct sparse or compressible signals.)
