      shape coefficient
    The otolith shape was described by seven harmonics from elliptic Fourier descriptors and by five indices of shape (coefficient of form, roundness, circularity, rectangularity, and ellipticity).
          
    We observed diurnal fluctuations of the circumnutation parameters with the phase of the highest trajectory length, the shortest period, and the highest shape coefficient (the most circular form) during the dark period.
          
    These seven factors include (1) length of creek, (2) average slope, (3) effective watershed area, (4) shape coefficient, (5) median size of soil grain, (6) effective cumulative rainfall, and (7) effective rainfall intensity.
          
    The morphometry of the neuronal body displayed significant alterations concerning area, shape coefficient, and contour index that were statistically increased for the CY-infected group.
          
    A modified bootstrapping procedure is described by means of which standard errors and confidence limits may be determined for the Penrose shape coefficient.

    Local erosion in riverbed around bridge piers has been the focus of research in China and foreign countries. Due to its complexity, studies on it have been conducted in a semi empirical and semi theoretical way. The scour formulae developed by China Academy of Railway Sciences in the sixties used the same method.

    Local erosion in riverbed around bridge piers has been the focus of research in China and foreign countries. Due to its complexity, studies on it have been conducted in a semi empirical and semi theoretical way. The scour formulae developed by China Academy of Railway Sciences in the sixties used the same method. The empirical coefficients including the coefficient of pier type were obtained through analysis of a large amount of experimental data from the lab and fieldwork. The formulae have played a great role in the survey and design of railway and highway bridges. But new and larger bridge piers have been built in the past few years. Hence we should study the new local scour coefficients of bridge piers. The lab study on the pier type coefficients of the original formulae have been expanded, employing the same pier type coefficient for the test method and the same water and sand lab conditions. Therefore the new pie type coefficients are comparable with the original ones and of the same system.

    由桥墩引起的局部河床冲刷一直是国内外学者关注的研究课题 ,因其因素复杂 ,研究大都采用了半理论半经验的方法 ,六十年代由铁道部科学研究院研究的桥墩局部冲刷公式就是采用了这种方法 ,公式中的经验系数包括墩型系数是借助大量的实验室实验资料和天然资料的分析得到的 ,该公式多年来对我国铁路与公路桥渡勘测设计起着重要作用。但近年来出现了新的大尺度墩形 ,需要研究其墩形局部冲刷系数。通过实验室实验对原公式中的墩形系数进行了扩充研究 ,填补了近年来跨江、跨海大跨度桥梁设计中发展的两种新型桥墩局部冲刷墩形系数。采用与原有墩形系数相同的实验方法和水沙实验条件 ,使新墩形系数与原有墩形系数具有可比性和系统性

    Turbulent horse-shoe vortex occurs when flow in alluvial river meets obstructions, such as bridge piers and their foundations. Local sediments in bed suspend and move with flow due to effects of the turbulent shear stress. Sand bed is eroded around bridge piers. The location of the piers and their foundations into the flow affects the local scour depth. In this paper laboratory experiments have been conducted for studying the scour maximum depth in the case of construction of bridge foundations. The variations...

    Turbulent horse-shoe vortex occurs when flow in alluvial river meets obstructions, such as bridge piers and their foundations. Local sediments in bed suspend and move with flow due to effects of the turbulent shear stress. Sand bed is eroded around bridge piers. The location of the piers and their foundations into the flow affects the local scour depth. In this paper laboratory experiments have been conducted for studying the scour maximum depth in the case of construction of bridge foundations. The variations of scour depth with the location of the foundation have been investigated and a technique of pier shape coefficient for calculating scour depth has been forwarded. The results of this paper have significant values in construction of bridges with large-scale foundations.

     天然河流中水流受到建筑物的阻碍时,产生紊动涡旋,局部河床泥沙在水流紊动剪应力作用下起动,并被涡旋流带向下游,建筑物局部河床因此受到侵蚀而下降,形成局部冲刷坑。跨河大桥桥墩的局部冲刷就是如此。桥墩及其基础与水深或河床的相对位置影响着局部冲刷深度的发展。本文通过室内试验研究了桥墩下部钢围堰基础施工的相对高程对河床局部冲刷最大深度的影响,探讨了工后钢围堰顶部处于相对水深的不同高度时局部冲刷发展的规律,并将这些影响因素用墩形系数法计入局部冲刷深度计算中,给出了计算公式。本文的研究对目前跨江及跨海大尺度桥墩基础工程施工具有指导意义。
