人们越来越感兴趣的是，是否有可能建立地面实验，直接探测银河系暗物质，假设暗物质可能由新型基本粒子组成。在过去的两年里，针对几种类型候选粒子的暗物质探测器的开发工作水平有所提高。现有的低本底探测器对某些类型的暗物质粒子有一定的限制，一些新的实验正在计划中，这些实验将能够改善这些限制。本文讨论了银河系暗物质的主要候选粒子，并总结了各种已提出的探测它们的实验想法，特别是用于轻轴子的电磁探测器和用于重中性粒子的核反冲探测器。对于后者，正在研究各种低温和电离技术。每一个这些的发展进展进行了总结，连同前景和计划，在不久的将来的具体实验。
There is increasing interest in the possibility of setting up terrestrial experiments for the direct detection of galactic dark matter on the hypothesis that this may consist of new types of elementary particle. The past two years have seen an increased level of development work directed towards dark matter detectors for several types of candidate particle. Existing low background detectors have set some limits on certain types of dark matter particle and a number of new experiments are now planned which will be capable of improving these limits.This review discusses the principal particle candidates for the galactic dark matter, and summarizes the various experimental ideas which have been proposed for their detection, in particular electromagnetic detectors for light axions and nuclear recoil detectors for heavy neutral particles. For the latter, a variety of low temperature and ionization techniques are being studied. Progress in the development of each of these is summarized, together with prospects and plans for specific experiments in the near future.
