depth contours meaning in Chinese
层面的等高线，描述相同的深度或时间值。
等深线
Examples
- All three basins are enclosed by the 1900m depth contour .
三个海盆都被1900米的等深线所圈闭。 - Within the 10 meter depth contour there are 69 , 600 hectares of shallow mud flat fit for sea culturing . the major cash aquatic products are of 214 species , 120 families and 21 kinds . the area of salt field is 1677 . 6 hectares
3万公顷，主要经济水产品有14类107科173种，淡水主要经济水产品有7类13科41种；且为粤东著名产盐基地，现有盐田面积167770公亩；全市有林面积20 - The waterway depth contour can be adjusted artificially in certain field . so the across of depth contours can be avoided effectively . in addition , the precision of depth contours is high and the speed of drawing is fast
在航道等深线的绘制方面，本文提出了一种新的航道等深线圆滑方法，可以在一定范围内人为调整等深线的张驰，有效地避免了等深线之间的交叉，并且等深线的绘制精度较高，绘制速度也特别快。 - This paper researches and develops the digital simulation software of 3d terrain in accelerating the producing speed of plane triangle - net , the smoothing of waterway depth contour , the construct of waterway curve plane function , the drawing of 3d graphics and the waterway simulation
本课题主要研究开发三维地形数字仿真软件，在提高航道平面三角网的生成速度、航道等深线的圆滑处理、航道曲面模型的建立、航道立体图的绘制及航道仿真等方面进行了一些研究和开发工作。
