The heat transfer and flow resistance performance of corrugated tube heat exchanger were examined by oil, water, and steam.

采用油、水、水蒸气对波纹管换热器的传热和流动阻力性能进行了试验研究。

Usually a bellows will buckle only under a very small torsion angle, and thus its utilities on torque transmitting are limited.

由于波纹管通常在很小的扭转角度下就会发生失稳，限制了其在传递扭矩方面的用途。

A new anchorage system for girder to obtain pretension stress at section top-edge in middle of span is shown. Based on the research of bi-prestressing beams inside test-room and the test of the prestress bar character, method for calculating the full size gird and choosing section are proposed. A new-style corrugated pipe which is shown in the paper is used, to solve the transformation of compressed thread bar and the contradiction between loss of friction resistance and pumping in pipe.
