standard contours meaning in Chinese
首曲线
Examples
- Simulation results show that the quick contour following algorithms can reduce the execution time of the standard contour following algorithm nearly 40 %
仿真结果表明，大多情况下，快速算法能够将轮廓跟踪的执行时间减少40 %以上。 - When catchment area , average channel gradient and catchment shape factor of designed culvert or bridge are known , a user can be convenient to get local parameters c , e and b from standard contour charts and easy to calculate flood flow just by a calculator . design period of flood flow is enormously shortened as well as a high precision . estimated flood flow through culvert or small bridge by new calculation model is generally less than by traditional methods , so that much cost is cut down a s reducing the span of culvert or small bridge
以75000km ~ 2的川中丘陵地区为试点研究区，绘制了该地区新模型的参数等值线图，率定了不同设计频率的改正系数，使设计者只需在地形图上获取集水面积，河道平均坡降和流域形状系数，在参数等值线图上查得桥涵所在地的相应参数，使用计算器即可迅速计算出设计流量，大大缩短了设计周期，且精度较高，设计的洪水流量一般低于传统方法，从而可减小桥涵跨径，节省投资。 - The principle of this approach is : during the second alphabetically pixel scanning of the labeling algorithm , the first pixel of each connected components is found , and a start - point table used for contour following is set up based on certain principles , thus the operation of search start points of the contour in the image is avoided , the execution of the standard contour following algorithm is accelerated
算法的基本原理是：利用标记过程寻找连通区域中第一个像素出现的位置，在此基础上根据一定原则确定轮廓起点，省略了在图像中逐像素搜索轮廓起点的过程，达到加速算法执行的目的。
