The key lies in producing enough great driving force of natural circulation at reasonable heatingtemperature difference to make masted tape self-rotate reliably in heat transfer tubes.
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。

This approach is not ideal because the offset will change over time due to self-heating and changes in the ambient temperature.
由于自热和环境温度的变化，偏移会随时间而变化，所以这种方法并不理想。

This paper presents an analytical thermal model considering via self-heating for estimating the temperature of metal wires and vias and the critical condition for hot spot formation within the vias.
