In experiment study , the author designed two models - small scale model and large scale model according to difference of experiment pool and analyzed the feasibility of the two models 在试验研究部分中，根据试验水池的不同，设计了两种模型? ?小比尺模型和大比尺模型，并分别对其可行性进行了分析。
The plane scale of model was 500 , vertical scale was 60 and varied ratio was 8 : 33 . the contrast trial . . utilizing trial of long series and typical flood test have been conducted 东庄水利枢纽渭河下游河道动床物理模型选定平面比尺为500 ，垂直比尺为60 ，变率为8 . 33 ，在此模型上进行了水库运用对比试验、长系列运用试验以及典型洪水试验。
The scale effects due to unsimilar bed risistance is discussed in detail , and the correct way of scour depth is supposed . at last , a new transport rate formulas of uniform or nonuniform bed load is given 本文还对由于阻力不相似而引起的比尺效应进行了较详细的讨论，从理论上给出了冲刷深度比尺效应的修正方法及新的均匀、非均匀推移质输沙率的计算公式。
This paper introduces the methods for performing full - scale laboratory tests on the interface shear resistance in the thermally insulated ocean pipelines for a certain project , and the test results are also presented for the designers to refer to 以某依托工程采用的单重保温管为例，介绍了各层之间抗剪能力的室内全比尺试验方法，给出的试验结果可供设计参考。
This paper has researched the regularity of crack similitude to the models of different scales , different amounts of reinforcing bar and different surface forms of steel reinforcement , through serial tests of six groups eighteen reinforced concrete simple beams models 摘要通过6组18根不同比尺的钢筋混凝土简支梁的模型试验，对不同比尺、不同钢筋根数及不同钢筋形式的模型之间的裂缝相似规律进行了探讨。
Furthermore , a plan of designing the small model having a step bottom is provided in the experiment of restricting model . and a plan of jetting from foreside and middle part of the large scale model is adopted in experiment , all these are our innovative points 此外，在小比尺模型试验中，还提供了一种断阶喷气试验设计方案，在大比尺模型试验中，采用了首中部同时喷气的方法，这些都是本文试验的创新之处。
The approach of physical model will take longer time and charge more money although it will give us some direct impression . because of the restriction by mode scale , velocity measuring is quite difficult . especially the flow feature is difficult to describe accurately 尽管物理模型实验给人较为直观的印象，但投资较大、周期较长，由于受模型比尺的限制，流速测量十分困难，尤其是水下流态难以得到准确描述。
Abstract : through study on energy dissipation of goupitang project on the wu - jiang river , the velocity field in the water cushion pool downstream ski - jump or drop was measured by hot - film anemometers on a fine model with scale 1 380 文摘:结合乌江构皮滩水利枢纽工程消能问题研究,用热膜流速仪在比尺为1 380的精细模型上量测了拱坝挑跌流在水垫塘内的流速场,并由试验成果分析了淹没射流在水垫塘内的消能过程,计算了消能率。
