结果表明,闸墩河海大学博士论文的存在抬高了水面线的位置,其中在闸墩头部尤其明显;墩型对流量系数和坝面压力影响较大,3A型闸墩相对于2型闸墩具有更大的流量系数和更小的坝面压力:不同的墩厚闸宽比t/b对泄流能力也将产生显著的影响,随着墩厚闸宽比的增加,坝面压力降低,而当t/b二0.2时溢流坝具有更大的流量系数。7本文建立的三维自由面湍流场模型能够比较准确地模拟带闸墩溢流坝三维过坝水流湍流场,可以针对不同的坝型、墩型、坝面布置形式以及不同的坝顶水头完成系列水力计算,为泄水工程建筑物的设计提供可靠的分析依据

Also, by using a novel offset architecture, as opposed to completely overlapped architecture, for the differential transmission pair, a 33% reduction of thickness is achieved in the design of a miniaturized common-mode filter with multi-layer LTCC technology. In view of increasing need of high-speed clock and data circuits to control their skew problems, a design of LTCC delay line is then conducted. To improve the waveform distortion associated with the microstrip/stripline-type meander delay line, a miniaturized high-frequency 3-D delay line with grounded guard traces is introduced. By means of 3-D structure, the 233 ps delay time, which requires extra board space amounting to a factor of 2.34 by stripline type meander delay line, can be shrunk into an EIA 1206 form factor.
