用家兔以头低位－２０°方法模拟失重时体液头向分布和运动减退生理效应的模型。用兔耳不开窗微循环观察方法，动态地研究机体在模拟失重时表浅微血管中血液流动状态以及内脏主要脏器微循环功能状态以及调节变化规律；用非常规的血液流变学测量方法，观察血液流变性特点。着重观察脑微循环的功能和结构变化对脏器乃至整个机体状态的影响。实验得出机体各脏器在１５ｄ实验中微循环功能状态的动态特性曲线及适应过程，这一变化特点与航天员飞行过程中对失重适应性反应相一致，并说明了在失重状态下心血管功能调节有明显牺牲次要器官以保护脑、心、肺等主要器官的机制，表明机体在失重条件下调控的整体性。
Rabbit head to head low-20 ° method to simulate the loss of body weight fluid head to the distribution and exercise to reduce the physiological effects of the model. With rabbit ears without microcirculation observation method to dynamically study the body during simulated weightlessness superficial microvascular blood flow state and visceral major organs microcirculation functional status and regulatory changes in the rules of unconventional hemorheology , Observe the characteristics of blood rheology. Focus on the observation of brain microcirculation function and structural changes on the organ and the whole body state. The dynamic curves of the microcirculation functional status and the adaptation process of each organ of the organ in the experiment of 15 days were obtained experimentally. This change characteristic is consistent with the adaptive response to weightlessness during the astronaut flight and illustrates the cardiovascular function Regulate mechanisms that significantly sacrifice secondary organs to protect major organs such as the brain, heart and lungs, indicating the integrity of the body’s regulation under conditions of weightlessness.
