| 1. | In this thesis , a novel and powerful horizontal afm system was first designed and built for surface observation in nano - technology 利用上述新方法,在国内外率先研制建立了新型卧式原子力显微镜系统,主要性能指标达到国内外先进水平。 |
| 2. | Surface observations of various meteorological elements are made by trained observers at the hong kong observatory headquarters , airport meteorological office and king s park meteorological station :训练有素的观测员在天文台总部机场气象所及京士柏气象站进行各种气象要素的地面观测。 |

| 6. | The wind fields and temperature fields data provided by " d files " from 14 surface observation stations around beijing area are used to produce the mean wind fields and the mean temperature fields over beijing area in summer and winter 用北京及市郊地区共14个地面气象观测站的全月数据顺序文件“ d文件”提供的风场及温度资料,采用逐时月平均的方法对北京及周边地区的冬夏两季的风场,温度场特征进行了研究。 |
| 7. | This information , together with surface observations of sunshine duration , global solar radiation , soil and grass minimum temperatures , evaporation and potential evapotranspiration , are essential for many fields of studies including climatology , hydrology , agriculture and civil engineering design 此等资料与及其他地面观测,例如日照时间太阳总辐射土壤温度最低草温蒸发量及可能蒸散量等,对于很多研究领域,包括气候学水文学农业及土木工程设计等,都是不可缺少的。 |
