The steam acts upon the surface of the water in the receiver, which surface only being heated by the steam, it does not condense, but the steam gravitates or presses with an elastic quality like air, and still increasing its elasticity or spring, until it counterpoises, or rather exceeds, the weight of the column of water in the force pipe, which then it will necessarily drive up that pipe; the steam then takes some time to recover its power, but it will at last discharge the water out at the top of the pipe You may see on the outside of the receiver how the water goes out, as well as if it were transparent; for, so far as the steam is contained within the vessel, it is dry without, and so hot as scarcely to endure the least touch of the hand; but so far as the water is inside the vessel, it will be cold and wet on the outside, where any water has fallen on it; which cold and moisture vanish as fast as the steam takes the place of the water in its descent.

&&蒸汽行为后,水面在接收端,而只是表面被加热水蒸汽,它不浓密,但相互依赖蒸汽或印刷机具有弹性质量一样的空气,并仍在增加其弹性,或春天,直到它网,而超过重量栏水警队管道,然后它一定会推到管;蒸汽则需要一段时间来恢复其权力,但它会在最后排放水出顶管,你可以看到外面的接收机如何当然水,以及如果它的透明度;,目前为止由于蒸汽载船,它是未经干燥,所以作为热几乎要忍受至少触摸的手;但到目前为止,由于水内的船只,将寒冷和潮湿对外面,那里没有水落下;其中寒冷和水分消失快蒸汽需地方水在其后裔。

Following, a experiment has been carried out, the incident waves with a frequency band of 200kHz-3 50kHz are used to the experiment, and a series of peak value-time curves are drawn each 10kHz, corresponding time are found through fitting peak value, thus the position of the defect is calculated accurately. The application of awl-shaped sensor head in the heat change water pipe experiment indicates that the ultrasonic guided waves may transmit nearly 50 meters in the pipe, which is not influenced by the elbows and makes it possible to test defects in long distance and large-scale. The water-load pipe experiment indicates that the displace and energy maybe leakage at the near-surface, which is significant for the further research.

A series of erosion-corrosion test has been done to J55 steel under the influence of current of gas-liquid phase by indoor self-made devices, and the corrosion mechanism of current of gas-liquid phase to oil pipe's inner surface has been got. The results show that oil pipe's inner surface will be corroded fleetly by liquid medium and corrosion products will form on it. But at the same time, the corrosion products or protective layer will be removed from the inner surface of steel pipes under the alternate impact of high speed gas and liquid flow, and on this bare steel surface corrosion film will form again and be removed again. Thus, by these ways the corrosion is exacerbated. Surface erosion-corrosion failure comes into being with the circulation of this process going on.

本文主要在气液两相流作用条件下,通过室内自制装置,对管材钢J55做了系列冲刷-腐蚀试验,结果表明,气液两相流对钢管内表面冲刷-腐蚀的机理是钢管内表面会受到液体介质的快速腐蚀,生成腐蚀产物,同时钢管金属表面不断被具有高流速的气液相交替地冲击,不断地从金属表面脱去保护膜或腐蚀产物,裸露的钢表面又会被介质快速腐蚀形成腐蚀膜后,再被两相流冲掉,如此反复,造成管内金属表面膜的连续破坏,使腐蚀加剧,最终导致钢铁表面的冲刷腐蚀失效。

Based on the integration of the results of acoustic andfluid dynamic analysis, this paper points out that synthetical acoustic and fluiddynamic performance of muffler can be obtained by using square expansion chamber,by stringing together several podgy expansion chambers, by applying noise absorbingmaterial on chamber walls, by making chambers and pipers co-axial, by adding filletson the end of intruding pipes, and by making the diameter of outlet pipe a little greaterthan the diameter of the inlet pipe.
