算法基本思想是：先对矩形网格4个顶点值按照其大小和相互位置关系分类，然后把矩形网格划分为若干个三角形网格，最后在三角形网格内完成等值线的追踪和填充。

The layout of airfield is designed and adjusted rationally by means of founding a noise prediction model, protracting noise isobars diagrams and using space analysis function of GIS, which is validated by the combination with structure instance.

机场内部营区噪声污染严重，因此，在营区规划初期对营区范围内噪声进行合理预测和规划就显得尤为重要，通过建立噪声预测模型，绘制噪声等值线图，利用GIS的空间分析功能，对营区布局进行合理规划和调整，并结合实例进行可行性验证。

Most strong earthquakes occurred on the large areomagnetic variation belts. The lateral heterogeneity of basement, which inferred by large areomagnetic variation, vailed stress concentration, earthquakes preparation and occurrence. We also get distribution of crustal thickness and continental deformation features in SYR from gravity data.

康定—绵阳一带刚性基底的阻挡造成了青藏高原下地壳物质向东的塑性流动被迫转向南东—南南东方向，进而造成了川滇菱形块体内广泛的地壳增厚，布格重力异常等值线呈向南东伸出的舌状是其地壳增厚作用的直观反映。

This text introduces the work principle of the method of controlled source audio-frequency magnetotellurics, analies the effect of this method in detecting buried fault in coal mine, And the means of field exploration in a coal mine in Shanxi solves the problems in design and production of coal mines and, proves that the advance forecast of such method in detecting buried fault in coal mine is reliable.

本文介绍了可控源音频大地电磁测深法的工作原理，并对隐伏断层的电性特征进行了正演计算。通过在山西某煤矿的实地探测分析可知，隐伏正断层的异常表现一般为横向电阻率等值线发生错断、并伴有同向扭曲现象，有比较明显的密集梯度带。

The results indicate that the 3D-QSAR model is significant and has good predictability, providing useful information for designing new good activity AHAS inhibitors prior to their synthesis.

根据CoMSIA模型的立体场、静电场、氢键给体场三维等值线图不仅直观地解释了结构与活性的关系，并且与用FlexX预测的结合模式相一致，证明了我们预测的结合模式是可靠的，为进一步设计高活性的标题化合物提供较好的理论指导。

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。

In this paper, the basic knowledge of GPS, CORS have been introduced briefly, and the theory and methods of refining the local geoid based upon GPS or CORS have been discussed in detail.

本文首先介绍了GPS、CORS的基本知识，详细阐述了基于GPS技术的昆明市大地水准面精化理论和方法，并利用多年基础测绘资料，确定了昆明市1000平方公里范围内数字高程异常等值线。

Combined with in-situ cases, the seepage flow patterns of air leakage in goafs with complicated shapes are described, and an accurate graph distribution solution of flow pattern is given.

结合现场实例，从宏观上描绘了复杂几何形状采空区的漏风流态(风压分布等值线和流函数线)，给出更准确的流态图形分布解。

But because isoclines are 2D, they cant form an intuitive, clear concept.

但是由于等值线是二维的，不能形成一个直观的、清晰的概念。
