The conclusion is that the "ω" shape suction champer has excellent hydraulic characteristic in different inlet flow conditions. Its hydraulic loss is small and velocity-averaged streamline angles on special cross sections are approximately 90°.

试验和数值分析结果表明：采用&ω&形后壁吸水室钟形进水流道在不同进水条件下均具有良好的水力性能，水力损失小，流道出口断面速度加权平均入流角接近90？

One type of blade airfoil with high efficiency of a general axial flow fan is adopted as original airfoil, and it is shortened according to different length scale, and then joined to the exportation circular arc of the original airfoil in the opposite direction. Assuring the streamline on the surface of the blade profile after smooth operation, a new kind of double-head anti-unsymmetrical S model airfoils has been structured to be researched in this paper.

采用一种效率比较高的普通风机叶片翼型作为原始翼型，按不同长度比例缩小原始翼型，反向搭接在原始翼型的出口圆弧处，经过光滑处理，保证叶型表面的流线形后，构成本文所研究的新型双头双机翼反向S型不对称翼型。

The part I of the experiment will be used a digital particle image velocimetry system to measure instantaneous and non-invasive ensemble-averaged flow fields inside the glass curtain of the ACC. Particularly for the reduced scale test section of ACC that are used in incinerator, we are used to observe the streamline distributions at the middle plane inside the glass curtain in various inlet velocity of the blowers for the one-row, two-row, three-row ACC and the glass curtain with and without holes.

本研究初期将藉由数位质点显像测速仪定量且非侵入式的量测技术，针对焚化炉用空气冷凝器的缩小维度测试件，在不同入口风速、冷凝管排数、玻璃帷幕有无开口方式下，观测其玻璃帷幕内之流体全域速度场。

The velocity, pressure and streamline distribution of the internal flow field of front guide impeller are analysed.

分析了前置导轮内部流场的压力、速度和流线分布情况。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
