本文对迄今为止国内外对返料立管和非机械阀的研究现状和研究结果进行了详细的综述，归纳总结了实验与锅炉实际运行过程中固体颗粒循环量的测量方法以及气固混合物通过孔口的流动特性。

The experimental results showed that the diameter of orifice had a great effect on the lower limit of the hung-up regime but not on the upper limit. However, the stagnant height in hopper, the angle of hopper, the length and diameter of standpipe had influence on the upper limit but not the lower limit.

这种方法不能反映混凝土和钢筋两种材料的非线性性质以及混凝土开裂后引起的应力重分布，并且不能有效地控制孔口的开裂，按照此方法计算的配筋量往往偏大。

The purpose of opening the orifice was to sluice. The influence of fluctuating pressure upon the dam was another problem which was concerned by engineer. The paper analyzed Shuangkoudu masonry arch dam. The result indicated that the dam natural frequencies which consider the dam and the reservoir water interaction have great different from the preponderant frequencies of fluctuating pressure, the dam's first rank of vibration was far away from the high energy region of the fluctuating flow, so the sympathetic vibration would not take place.

坝身开设孔口主要目的是为了泄洪，泄洪时水流脉动压力对坝体结构动的影响是设计人员关心的另一课题，论文针对双口渡浆砌石拱坝进行了分析，研究结果表明：在考虑坝体一库水相互作用时坝体自振频率和水流脉动压力的优势频率相差较大，坝体的一阶振动远离脉动水流的高能量范围，二者不会发生共振。
