ripple ratio
[电子] ripple factor
ripple coefficient
- ② 波节管、波纹管换热器,传热系数大;
tube, corrugated tube heat exchangers, heat transfer coefficient large; - 结果表明,波纹管换热器的总传热系数比光管高1.5倍以上。
The result shows that heat transfer coefficient of corrugated tube heat exchanger is over1.5 times than that of bare tube. - 用于测定各种织物的悬垂性指标:悬垂系数、活泼率、织物曲面波纹数和美感系数。
to test the overhanging capability of all kinds of fabrics, include overhanging factor, lively rate, corrugated surface of the fabric.
