The velocity of ultrasonic propagation, calcium content, and femur size of rats exposed to actual and simulated weightlessness were investigated. The exposure slowed down the ultrasonic velocity in bones. The effect of the calcium content on the ultrasonic velocity in various bone sites was different: as a rule, there was a positive correlation in diaphyses and a negative correlation in epiphyses. These specific features should be taken into consideration when new methods of bone ultrasonic diagnostics will be developed.
研究了暴露于实际失重和模拟失重环境下大鼠的超声传播速度、钙含量和股骨尺寸。这种暴露使骨骼中的超声速度减慢。钙含量对不同骨部位超声速度的影响不同：通常，骨干中存在正相关，骨骺中存在负相关。在开发新的骨超声诊断方法时应考虑这些特定特征。
