扫描

In topographic map, especially for city area, most of features are central symmetry and axial symmetry. By means of extracting features with symmetric figure first and then vectoring them according to their geometric characteristic, accuracy and efficiency can be increased and data sizes can be reduced.

在地形图中，轴对称和中心对称的要素占据着相当大的比例，特别是城市地形图中，房屋建筑等具有对称形状的要素占据了地形图中要素的绝大部分，在扫描图中首先对这些要素进行提取，进而根据特定要素的几何特征矢量化，可显著地提高矢量化精度和效率，减少数据的储存量。

Glass-ceramics of CaO-Al2O3-SiO2 system doped with ceria were prepared by sintering method and were characterized by differential thermal analysis, X-ray diffractometry, scanning electron microscopy and property measurements.

采用烧结法制备添加氧化铈的CaO-Al2O3-SiO2系微晶玻璃材料，并对其进行差热分析、X射线衍射分析、扫描电镜观察和性能测试。

In the present study, 22 certified milk samples without melamine were collected, then 50 adulterated milk samples with added different content of melamine (0.1-1 500 mg·kg-1) were prepared. The near-infrared spectra of these milk samples were measured. The possibility of using NIR spectra to detect melamine in milk was studied.

采集了22个合格液态牛奶样品，并制备了50个掺入不同含量三聚氰胺(0.1～1 500 mg·kg-1)的牛奶样品，应用近红外光谱仪扫描其透射光谱，研究利用近红外光谱快速检测牛奶中三聚氰胺的可行性。

In this project, the microstructures of a kind of green chafer cuticle are observed with a scanning electron microscope and other microscopic instruments. The results of the observations show that the basic microstructural characteristic of the cuticle is similar to man-made fiber-reinforced composite, the laminated chitin fibers embedded in protein matrix provide the strength and toughness of the cuticle.

本项目利用扫描电镜等细观仪器设备对绿金龟子外甲壳进行细观观察，发现其基本结构特征类似于人工合成纤维增强复合材料，其几丁质纤维以层状的形式埋设在蛋白质基体中起增强的作用。

Using optical microscope, manual artificial heavy concentrate, electron microprobe and scanning electron microscopy, we tested major gold- bearing minerals in Zhaishang deposit. Pyrite and scheelite are the most important gold-bearing minerals. Quartz, limonite, and chalcocite are the secondary gold-bearing minerals. Calcite, siderite, barite and other minerals do not contain any gold.
