The physical model and mathematical analysis methods of vapor condensation in the presence of high concentration of noncondensable gas on the surface of the vertical spirally grooved tube based on film theory have been established.

Abstractly, using ANSYS software simulates roll-pressing course of spirally grooved tube by three-dimension numerical simulation and experimental research.

在理论上，应用有限元软件ANSYS对螺旋槽管的滚压过程，进行了三维数值模拟研究及试验研究。

Lastly, experiment on various spirally grooved tube is made to obtain relationship between diverse parameters and performance of heat exchanger.

最后，将滚压成型生产的各种螺旋槽管进行了换热性能的试验研究，得到了不同的结构参数对管材换热性能的影响规律。

Spirally grooved tube is the important one of them.

螺旋槽管（亦称螺纹管）是其中的一个重要分支，它是一种优良的高效异形强化传热管件。

China has a history of relatively benign price increases spiralling quickly into double-digit inflation.

此前，中国有过相对较温和的价格上涨迅速演变为两位数通胀的历史。

Ukraine has sharply raised its benchmark refinancing rate by 10.5 percentage points to 30 per cent, in a desperate move to temper spiralling inflation and halt its sinking currency.

乌克兰将其基准再融资利率急剧提升了10.5个百分点至30%，这一绝望举措是为了抑制加速上升的通货膨胀，并制止汇率的暴跌。

This week he was on the streets again but inspired by more prosaic complaints: rising heating prices, spiralling inflation and a collapsing currency.

本周，他再次走上街头，但动机是更为琐碎的生活抱怨：不断高涨的供暖价格、螺旋式上升的通胀以及汇率暴跌的货币。

B: You can set up the fax machine to print a completion receipt. It will also print an error page if the fax does not go through.

B：你可以设定传真机打印一张完成回执，如果传真发送失败的话，传真机也会打印一张发送失败回执。
