Results showed that the topsoil (10cm) pH increased with increasing distance from bole. The minimum topsoil pH presented on the region of bole base. Some contour lines of topsoil pH were concentric circles which centered in boles.

结果表明，两树种树干周围表层土壤(10cm)的pH均由树干基部向外围逐渐增加，pH最低值常出现在树干基部附近，有的树干周围土壤pH等值线呈近似同心圆的分布。

METHODS: Designed a simulated acetabular cup with serial concentric circles which pass through the same polars and represent anteveration of 0°, 10°, 20°, 30°, 40°.

自制系列前倾角模拟髋臼假体模型，分别代表0°，10°，20°，30°，40°前倾角。

Basic characteristics of cosine transform spectrum were analyzed, where contour lines of 2D cosine transform of point mass present the shape of a quarter of concentric circles and the number of counter become small along with the increasing of wave numbers. 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 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。

To improve the measuring precision of photoelectronic measurement system for curvature (important status parameter of cannon), a real-time distortion correction method with concentric circles as onsite standard is proposed and a set of measuring apparatus with self-center adaptation is designed.

为了提高光电测量系统对火炮重要静态参数——弯曲度的测量精度，提出了一种基于同心圆现场定标的实时畸变校正方法，并设计了一套自定中测量装置。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
