摘要
归纳了模型变态的三种主要方式,重点对垂直比尺与水平比尺不同(λ_h≠λ_l=λ_B)的方式进行了介绍,分析模型变态对水流运动相似的影响,推导建立了其变态模型比尺关系,并重点推导出了矩形、梯形断面河渠的糙率比尺关系式。
Three modes of the distorted model are summarized herein with the emphases on the mode of the difference between the vertical scale and horizontal scale（ λh≠λl= λ B ）, and then the influence of distorted model on the flow kinematic similitude is analyzed with the deduction of the scale relation of the model, lastly, the scale relationship between the roughness of both the rectangle and the trapezoidal channels is emphatically deduced as well.
