中心线

The line representing the centerline feature should be located in the center of the real-world centerline.

代表中心线的线应设在现实世界的中心线的中心。

The first conductivity base board comprises: a base material, a first projection, a second projection and a light spacer; the first projection and the second projection are installed on the base material with central line symmetry, the second projection is the image structure of the first projection relative to the central line.

第一导电基板包括一底材、一第一凸块、一第二凸块及一光间隔物，第一凸块及第二凸块以对称于一中心线的方式设置于底材之上，第二凸块为第一凸块对应于此中心线的镜射结构。

Two problems were solved in numerical calculation, one was that a term of 1/r in Maxwell was divergence in cylindrical center where r=0, another was that the value of optical field at cylindrical center was difficult to decided when the cylindrical center set as a boundary condition in Maxwell equation, So the values of optical field need just calculate from cylindrical center to cylindrical boundary, comparing from cylindrical boundary to cylindrical boundary, near upon half CPU time and RAM saved.

计算中解决了在圆柱中心线上Maxwell方程存在发散项1/r以及用圆柱中心线作为边界条件时，中心线上光场值难确定的问题，因而光场只需从圆柱中心计算到圆柱边界，和以圆柱的两条边做为边界条件比较，节省了将近一半的计算时间和计算机存储空间。

He unbuttoned successively in reversed direction waistcoat, trousers, shirt and vest along the medial line of irregular incrispated black hairs extending in triangular convergence from the pelvic basin over the circumference of the abdomen and umbilicular fossicle along the medial line of nodes to the intersection of the sixth pectoral vertebrae, thence produced both ways at right angles and terminating in circles described about two equidistant points, right and left, on the summits of the mammary prominences.

他那双手的轨迹从参差不齐、卷缩起皱的黑色体毛的中心线——也就是自骨盆底到下腹部肚脐眼周围那一簇簇体毛，又沿着节结的中心线进而延伸到第六胸脊椎的交叉点，从这里又向两侧丛生，构成直角形，在左右等距离的两个点，即环绕乳头顶端形成的三角形收敛图形的中心线——穿行。

This approach uses the geometric features and radiation features of the road, according to the small amount seed points given by the user, each point in the road centerline can be gotten. Then an adaptive gray template is used to adjust each point in the road centerline. Finally, least square method and Newton iteration method are adapted to each point in the road centerline to fit a polygonal line.

该方法利用道路地物的几何特征和辐射特征，根据用户提供的少量道路种子点，利用自适应灰度模板对道路中心线上的每个点进行调整，最后采用最小二乘算法和牛顿迭代法对调整后的道路中心线上的每个点进行拟合，以此获得趋近于道路中心线的最佳折线。
