The research result demonstrates that along with the increment of reynolds number , the root mean square value of outer fluctuating magnitude of the external diameter in fall frequency band increases , the root mean square value of fluctuating magnitude of the external diameter in high frequency band decreses , demonstrating that the fluctuation of flexible pipe wall changes fluctuation don field of original rigid pipe , large - size eddy motion increases and small - size eddy motion decreases , this reduces energy loss and increases friction reduction effectiveness
研究结果表明：随着雷诺数的增加，全频带的外径脉动的均方根值加大，但高频带外径脉动的均方根值减小，说明柔性管管壁脉动确实改变了原刚性管的脉动流场，大尺度涡的运动加剧，低尺度涡运动减弱，从而使得能量损失减少，减阻效果增大。
Another reason is a patient tired , lack of power , carry momentum decreases , the mobile level of each systems all lowers human body , flowing flesh is in bowel flabby condition , colonic motion is abate , send excrement and urine to pass in the retention period inside bowel long , moisture is absorbed excessive , defecate eduction is difficult
另一原因是病人倦怠，乏力，运动量减少，人体各个系统的活动水平均降低，肠平滑肌处于松弛状态，结肠运动减弱，致粪便在肠内停留时间过久，水分被吸收过度，大便排出困难。
