The spectrum of vertical rectangularcylinder put up periodic zero counters which mark off quadrate areas, the values of counter in each areas alternately change between the plus and the minus, and with the increasing of wave number, the values of counter present attenuation character alike e exponent.

分析了点质量和直立矩形柱体重力异常余弦变换谱的基本特征：点质量二维余弦变换谱等值线呈1/4同心圆形状，等值线随着波数的增大而变稀；直立矩形柱体谱出现了周期性变化的零等值线，该等值线将非零等值线划分为a×b个矩形区域，而且等值线值在各矩形型区域中正负交替变化，随着波数的增大，不同的矩型域中等值线值呈e指数衰减特征。

As a first step to industrialize this focusing coal liquefaction technology, it is essential to study the multiphase transport characteristics of this new type reactor. In this paper, mass transfer and mixing characteristics of a three-phase continuous loop reactor with a concentric draft tube were measured by the dynamic dissolved oxygen and saturated KCl solution pulse trace methods,with glass beads as solid phase, air as gas phase and tap water as liquid phase, respectively.

本文在同心内置Φ 0.14×1.5m导流筒的Φ 0.2×2.5m有机玻璃环流反应器中，以空气和水为气、液相，玻璃珠为固相，分别利用动态溶氧法与饱和KCl脉冲示踪法测量了液相体积传质系数和轴向分散系数，考察了表观气速、进料浆速、固含率、固相颗粒直径、液相表面张力以及操作方式对上述两个传递参数的影响规律，并将实验结果关联为量纲为1关联式；同时，根据环流反应器的结构特点，建立了传质系数分区模型和轴向分散系数分区模型且分别获得了解析解，对床层传质和混合的不均匀性做了理论分析。

As the contour of a wheel rim is easier to detect than the contour of a wheel, and the contour of a wheel rim and the contour of a wheel are approximately concentric circles on the same plane, we first detect the contour of the wheel rim, the center of the wheel rim and the contacting point between the wheel and the ground, then we detect the contour of the wheel via the invariance of cross ratio under projective transformation.

由于提取钢圈轮廓比提取车轮橡胶轮廓容易，而且钢圈轮廓和车轮轮廓可以近似看作同一平面上的两个同心圆，所以在本文中，我们首先提取钢圈轮廓、钢圈圆心和车轮与地面接触点在图像上的投影，然后利用射影变换保持交比不变的性质求出车轮轮廓。
