查询词典 friction roller

The results indicate that the temperature at the surface of roller contacted with bar increases rapidly at the beginning of rolling, and it tends to periodically vary along with the rolling process, and this process will cost about 2 h. The temperature of the roller surface reaches the top point which is about 300 ℃ when the roller is circumrotated to position contacted with bar. New assembled milling rolls have excellent result in milling process.

研究结果表明：与轧件接触的轧辊表面的温度在开始轧制时迅速上升，随着轧制过程的进行，温度趋于呈稳定周期性变化，温度达到稳定的时间大约为2 h；当轧辊旋转到与轧件接触处，温度达到最高，最高温度约为 300 ℃，此时辊套轧辊结构稳定，据此生产的组合式轧辊在轧制过程中性能优越。

Up till now, the main pump types used in CPB are roller pump and centrifugal pump, but these two kinds of pump both have their own disadvantages. When roller pump is used, the blood cells will be destroyed severely and when the pipeline is kinked, air will be transported into body or the conduit will be broken. The function of centrifugal pump is better than that of roller pump, but now, this kind of pumps are all designed for adults, and when the flow rate is low, the function of protecting the blood is not significant.

目前，滚轴泵和离心泵是心肺转流中的常用泵型，但是滚轴泵对血液有形成分的破坏较严重，而且有引起泵管的崩脱和大量气体泵入体内的危险性；离心泵虽然在性能上优于滚轴泵，但目前的离心泵大都是为成人设计的，而且在低流量时在血液破坏方面的优点不明显，此外它们还有一个共同的缺点就是预充量均大，因此两者都不适合在幼婴儿体外循环中应用。
