• 中文摘要： 利用透明而堅固之材料研製一小型低壓室，可以耐受相當於78000呎高空之氣壓（即1/33之大氣壓）。此小型低壓室內 可放一小實驗動物（例如：小白鼠，大白鼠，天笠鼠，蛙或蟾蜍），並可將此室放於顯微鏡之鏡台上，藉此觀察實驗動物 之某器官（或細胞）於遭受減壓時之情況，必要時?可利用顯微鏡攝影術加以研察。此種設計，可避免觀察者隨伴實驗動 物進入低壓室。否則，觀察者將與實驗動物同時遭受缺氧及減壓症之威脅。 如將具有窗洞之不?鋼板加於此小室之底部及蓋部，則此小室即可耐受四個大氣壓，故?可藉此進行加壓及高壓氧之 研察。此外，因X射線可透過此小室，故?可以X射線攝影術進行減壓及缺氧或加壓及高壓氧之研究。此種小室之設計， 將有助於航空醫學及環境生理學之研?。

This chamber can accommodate a small laboratory animal. Such a miniature chamber can be placed on the stage of a large working distance zoom-stereo microscope so that the effect of hypoxia and decompression on certain living organs or individual cells can be microscopically observed and photographed. During altitude study it is not necessory for the investigator to accompany the experimental animal into the decompression chamber. The miniature chamber can be pressurized up to 4 atmospheres for hyperbaric research. The effect of simulated high altitude or hyperbaric environment on the experimental animal can also be roentgenologically studied by means of this chamber. It is possible that such a miniature chamber may find increasing use by investigators not only in aerospace medicine, but also in environmental physiology.
