6) twisted tape
螺旋扭带
1.
The key lies in producing enough great driving force of natural circulation at reasonable heating temperature difference to make twisted tape self-rotate reliably in heat transfer tubes.
自然循环自动清洗式蒸发器是解决蒸发器结垢问题的理想方案,其关键是能否在合理的加热温差下产生足够大的自然循环推动力,足以带动自动清洗螺旋扭带可靠地自转。
补充资料：脐带扭转
脐带扭转
较少见。脐带顺其纵轴扭转9～11周，可使脐血管嵌闭，胎死宫内。过分扭转的脐带多在近胎儿脐轮部变细坏死。脐带扭转在胎儿出生前很难诊断。
