The study of comparison of corneal diopter measured by corneal keratometer and corneal topographer 角膜曲率计与角膜地形图仪测量角膜屈光度的对比研究
2.
Analysis of measuring corneal refractive power by corneal topographer compared with by keratometer 角膜地形图仪和角膜曲率计测量角膜屈光力的差异分析
3.
The terrain affect spatial distribution of precipitation by way of macroeconomics topographer and parcel height above sea level . the results show that the relativity of precipitation and macroeconomics topographer is good in time scale 研究发现，在时间尺度上，降水与宏观地形因素有良好的相关性；在空间尺度上，降水与海拔高度有较好的相关性。
