对试车中遇到的干气密封频繁损坏、轴振动、泵输出量逐渐下降等原因进行了系统分析。

A systematic analysis is made of the causes for the frequent damage of dry-gas seals, axle vibration and gradual decrease in pump delivery encountered during the test run.

心输出量增加，心脏收缩加强能泵更多的血液，心搏量增加，左心室壁变厚(更多肌肉)，心脏对氧气的需要减少。

Increases Cardiac Output, stronger heart contractions pump more blood, increased stroke volume, thickens left ventricle wall (more muscular), decreases hearts' oxygen requirements.

波振幅的改变与心输出量及心脏的泵血功能，尤其是肺动脉楔压之间无明显关系。

The variation of R wave amplitude has little relation with cardiac output, heart pumping function, especially with pulmonary wedge pressure.
