航天时动物给水方式是航天动物生活条件保障中最复杂的任务之一。因为在失重条件下水同其他所有液体一样会满舱漂浮,动物无法饮用,所以普通的饮水装置不适宜在航天条件下使用。为此曾建议采用各种吸水体、吮吸管和带网格底的饮水装置。但是,该装置,很难在地面条件下检查它们的性能。而且,为保障每天供给 Space animal water supply is one of the most complex tasks in ensuring the living conditions of space animals. Because under the conditions of weightlessness, water, like all other liquids, flies in a full space and animals can not drink, ordinary drinking water devices are not suitable for use under aerospace conditions. For this reason, various types of water absorbers, sucking tubes and drinking devices with grid bottoms have been proposed. However, it is difficult for the device to check their performance under ground conditions. And, to protect the daily supply
