查询词典 topographic

The first is how to adequately define topographicst ructure morphol- ogically or hydrologically, and the second is how to design algorithms for the defined topographic structure. From the improving the approachs of the filling depressions and making gradient of plain in DEM, the extraction efficiency and result accuracy are better than existing methods and better fit to deal with the mass data of DEM.

通过对DEM中的洼地和平原区域处理算法的改进，使效率和结果准确性等方面都有了明显的改进，从而更加适合于对大范围流域的DEM数据进行处理与信息提取。

Topographic map of the pelvis expresses the depth of all parts of the pelvis, the projection of important blood vessels and nerves in the pelvis imaginarily and directly. To understand deeply the topography map of the pelvis may prevent vital blood vessel and nerve from accidental injury during the operation of internal fixation of pelvic fracture and acetabular fracture.

As revealed by the voltage topographic maps and the tomographic mapping, the source location of the distinct N1 is in the occipitotemporal areas.

并且，与单纯形状知觉任务相比，图形形状和空间位置知觉任务表现枕颞区N2波幅的显著减弱，P3潜伏期的王著缩短，额区的P2波幅的显著减弱；(3)脑电地形图与高分辨率断层成象显示，两种任务的特征波N1成分均来源于双侧的枕颞皮层，表明两种任务均涉及到与物体形状识别相关的视皮层腹侧通路，而差别波dN2成分来源于左侧枕颞区，暗示特征加工的差异主要发生在左侧枕颞区。

The orthograph map is a new map which integrated by the remotely sensed image and the simplified topographic map, in the digital regional geological survey, the orthograph may be regarded the important information resources of geo-survey, the handy geo-maps of geo-workers outside and the geo-carriers of geological features.

正射遥感影像地图是遥感影像与简化地形图复合而成的一种新图，在数字区调中，正射遥感影像地图可以作为地质填图的数据采集的重要信息源、区调地质测量的野外工作手图以及区域地质等要素的载体。

It is now a first-rate national center for ophthalmology. Some of the projects rank high internationally, for example, the success of treating 30,000 cases of myopia with LASIK. For the success of the operations, the center introduced sophisticated medical equipment, e.g. the first personalized LASIK. For optimal results, the center used the most sophisticated cornea topographic map, cornea pachymeter, automatic plate shaper and eye ground confocal laser scanning system, making the operations a more sophisticated project. Moreover, as all the doctors have rich clinical experience and expertise, and with painstaking efforts, they acquired great skills and familiarity with the medical equipment, resulting in what is "the man-machine unity".

一些项目已达到国际先进水平，如以该中心成功完成30000例准分子激光治疗近视为例，为了做好准分子激光治疗近视手术，该中心不仅引进了先进的治疗设备，如在我国率先引进了第一台个性化准分子激光治疗近视系统，而且为了严格把关，选择最佳治疗效果，又启用了最先进的角膜地形图、角膜测厚仪、微型自动角膜板层成型刀和眼底共焦激光扫描系统等，使准分子激光治疗近视手术成为更完善的系统工程，加之该中心医生大都从事眼科临床多年，有丰富经验和深厚知识底蕴，通过刻苦努力，很快做到&人机合一&，娴熟地掌握了最先进的眼科诊疗武器。

So far, the development of digital photogrammetry, both in theory and in practice, mainly around the use of air photogrammetric mapping topographic maps, and for digital close-range photogrammetry little studied.

Combining digital photogrammetry with traditional planimetric method, the working process is described of using digital planimetric photogrammetry to maintain topographic maps in plain area.

通过结合数字摄影测量与传统综合法，从生产实践的角度选择平坦地区地形图的修测方法，对平坦地区的修测方法数字综合法的作业流程进行详细地阐述。

Four sets of actual aerial photos are used to test;which are at different scale and in different terrain.The empirical results verify that image elements of exterior orientation obtained by a POS can satisfy the accuracy requirements of topographic mapping,no matter which scale and terrain the empirical block is classified to.However,to satisfy the accuracy requirements of object point in elevation,the accuracy requirements of exterior orientation elements are at least one time higher than that in planimetric mapping.
