| 摘 要： | 失重或模拟失重引起下肢顺应性的增加，使立位时有较多的血液潴留在下肢，回流至右心房的血液减少，从而促使心输出量和动脉血压的下降，因而其变化是失重或模拟失重后立位耐力下降的主要机理之一，其研究对于深入理解立位耐力的下降机理和发展对抗方法具有一定意义，本文对失重或模拟失重时下肢顺应性的变化，测量方法，变化机理和防护方法等方面进行了论述。

| Abstract: | weightlessness or simulated weightlessness causes increase of leg compliance. It leads to more blood pooling in the legs and less blood returning to the heart during orthostatic test, which may partly explain the occurrence of orthostatic intolerance induced by weightlessness or simulated weightlessness. This article is a review covering published materials about the methods of measurment, mechanisms and countermeasures of the increase of leg compliance during weightlessness or simulated weightlessness. |
