地形图

Four digital elevation models were generated from topographical mapsof the Yellow River delta, which were surveyed in 1956, 1967, 1980 and 1995 in ascale of 1:50 000 respectively. Knowledge on deltaic land subsidence in the deltafrom 1956 to 1995 was obtained through spatial analyses on these DEMs, andspace-time variation rule of land subsidence was obtained through statistical analysestoo.

本文收集了黄河三角洲地区1956年、1967年、1980年和1995年四个时期的1：5万地形图，提取高程信息，应用地理信息系统软件生成数字高程模型并展开了相应的空间分析，得到各个时间段内黄河三角洲的地面沉降速率图，通过对各沉降速率图的统计分析得出了三角洲地区地面沉降的时空变化规律。

The biggest difficulties in gravimetric observations are to get a first class map and the exact location of every measurement

重力测量中最大的困难就是取得高精度的地形图以及确定每一测点的精确位置

Result showed that using digital map and ANUDEM software can generate hydrologically correct DEM of meso-scale in the loess hilly region.

随着科学技术的发展，虽然DEM可以通过遥感数据直接提取，但迄今为止，最为成熟、经济可行的方法是利用数字地形图插值建立DEM。

Result showed that using digital map and ANUDEM software can generate hydrologically correct DEM of mesoscale in the loess hilly region.

结果表明，利用ANUDEM和1：5万地形图插值建立的黄土丘陵区DEM3个主要参数分别为：分辨率10m，迭代次数35，第二糙度系数0.7。

Based on the existing data of the Yangtze delta area, a preparatory simulative experiment have been done by the model on the sea-land change course in Yangtze delta area since l0000aBP, and a good simulative effect are obvious from the hypsometric paleotopographic map and 3D color shaded-relief map which exported from the model. That provides a visual scene to analyze and discuss the Yangtze delta evolution, coastline shifting, even the relationship between the ancient civilizations migration and environments.

利用海面—地面系统的模拟模型，对长江三角洲一万年以来的海面—地面变化过程进行了重构和反演，获得了一套该地区的古地貌和海陆关系演变图，它包括等高线、晕渲图、三维图等三种不同表现形式的地形图，为分析讨论长江三角洲地区地貌发育、岸线变迁乃至古代文明的迁徙和兴衰与环境的关系提供了很直观的场景。

Methods: A total of 366 eyes with keratoconus were subjected to wear proper RGPCL. Keratometer and corneal topography were used to determine the central cornea astigmatism, apex K value, apex decenteation distance, SRI and SAI before, 12 and 18 months after wearing RGPCL.

对圆锥角膜患者选配合适的高透氧RGPCL，分别于配戴前及配戴后12、18个月行角膜曲率计和角膜地形图检查，采集角膜中央散光值、锥顶K值、锥顶偏心距离、SRI、SAI等参数，进行统计学分析。

The Topcon KR-8100 automatic keratometry and the TMS-4 comeal topography can not be considered as interchangeable.

KR-8100自动角膜曲率计与TMS-4角膜地形图两种测量方法在临床上不能替代使用。

Objective To evaluate the agreement of measuring corneal power and astigmatism axis between automatic keratometry and corneal topography on ametropia' children.

目的 比较KR-8100自动角膜曲率计与TMS-4角膜地形图仪测量屈光不正儿童角膜屈光力及散光轴向的差异，并对两种测量方法进行一致性评价。

Keratometry was measured with corneal topography,corneal central thickness and eye axis were measured with type A ultrasonic machine,and the data were statistically analysed with Excel 97 software.

在进行PRK治疗的患者中，根据屈光度将278例(538只眼)患者分成低、中、高和超高度四组，应用角膜地形图仪测定角膜屈光力，A型超声波测定眼轴及角膜中央厚度，数据用Exce 197软件计算处理。

Methods Keratometric reading with Topcon KR-8100 automatic keratometry and comeal topography with the TMS-4 on 53 ametropia' children, 106 eyes were compared. Difference in measurements of steep meridian power magnitude Ks, flat meridian power magnitude Kf, astigmatism magnitude Ks-Kf and location as well between the two methods were assessed using paired t test.Bland-Altmann method was used to evaluate the agreement of the two methods.

采用KR-8100自动角膜曲率计及TMS-4角膜地形图仪对53例（106只眼）屈光不正儿童进行测量，应用配对t检验对两种方法测量的陡峭子午线角膜屈光力、平坦子午线角膜屈光力、角膜散光Ks-Kf大小及轴向进行比较，并应用Bland-Altmann分析对两种测量方法进行一致性评价。
