比例尺

In traditional reservoir capacity calculation, a planimeter is used to obtain a reservoir capacity from topographic maps and large scale topographic maps are needed if high accuracy is required.

传统的库容计算方法是在已有的地形图上采用求积仪法进行，当精度要求较高时，需到现场实测更大比例尺的地形图。

Computer aided compilation with small-scale relief map is a complicated piece of work. The control of the data precise is importance and difficulty. It is not only an important code to judge the map quality,but also important precaution to complete rnapping successfully.

小比例尺地貌图的计算机编制工作是一项复杂的工程，其中数据精度的控制是难点也是重点，它不仅是衡量地图作品质量好坏的一个重要标准，也是制图工作能否顺利进行的重要保障。

The model was designed with 1: 4 scale, strips width of protection tillage and tradition farming are uniform, to analyze the construction characteristics of the wind velocity flows, the wind velocity lowering rate compared with the wind velocity of farmland and aerodynamic roughness along lengthways of strips under the different experiment wind velocity, diverse width of strip, dissimilar residual stubble density and residual stubble height term.

模型比例尺取1：4，保护性耕作带带宽和裸露带带宽相等，分析不同实验风速、不同带宽、不同作物残茬密度及不同作物残茬高度情况下，风速流场特征、沿带纵向对应裸地风速降低率状况和空气动力学粗糙度。

What is the relationship between the scalar and spatial resolution of the map ?

我感觉是这样的：地图的比例尺和图像分辨率是什么关系？

A large number of subjects in the following interview prefer distance cue due to its comprehensibility of proportional scale. The direction should mark toward the north, and sign marking left or right turn has no practical meaning in use. Route cue and touch time have no significant difference, and however, for the visual impairs, positive assistances are found in memorizing route.

在后续的受测者访谈中，多数受测者偏好使用距离标示，因为此标示可以增进比例尺的概念，方向标示应该使用指示北方的方式，左右方向的标示并无使用上的实际意义，路径标示虽然在触摸时间上无显著差异，但是，对於视障者理解并且记忆路径有正面的帮助。

Based on technical processing of high-resolution SPOT images and aerophotos, detailed mapping of offset landforms in combination with field examination and displacement measurement, and dating of offset geomorphic surfaces by using carbon fourteen (14C), cosmogenic nuclides (10Be 26Al) and thermoluminescence methods, the Holocene sinistral slip rates on different segments of the Altyn Tagh Fault are obtained. The slip rates reach 17.5 mm/a on the central and western segments west of Aksay Town, 11 mm/a on the Subei—Shibaocheng segment, 4.8 mm/a on the Sulehe segment and only 2.2 mm/a on the Kuantanshan segment, a easternmost segment of the ATF. The sudden change points for loss of sinistral slip rates are located at the Subei, Shibaocheng and Sulehe triple junctions where NW-trending active thrust faults splay from the ATF and propagate southeastward.

在高分辨率SPOT卫星数字影像和大比例尺航片处理、断错地貌制图、野外核实与位移测量基础上，利用宇宙成因核素（10Be、26Al）、碳十四（14C）和热释光等多种测年手段，厘定了各断错地貌面的形成年龄，得到了阿尔金断裂带不同段落全新世左旋走滑速率：阿克赛以西的中、西段左旋走滑速率可达17.5 mm/a，肃北—石包城段为11 mm/a左右，疏勒河口段减少到4.8mm/a左右，东端宽滩山段仅约2.2 mm/a，左旋走滑速率突变点位于阿尔金断裂带中东段存在分支活动逆断层向南东扩展的肃北、石包城和疏勒河等三联点上。

On the basis of scaleless transform of DEM data, this paper introduces a method of extracting stream network after the generalization, and the fractal transformation of square root model, which is the same with the quantity-fixed generalization model of the stream networks.

本文在DEM数据无级变换的基础上，从DEM中提取出综合前后的河网，并引入分形扩展的方根模型，得到适用于河网的定量综合模型，从而评估出变换后DEM的比例尺。
