無機納米粒子是特徵緯度尺寸在納米數量級的粒子,是一種介於宏觀固體和分子的亞穩中間態物質。Its main contributions include the following several aspects : firstly, the dissertation constructs the mathematic model of short baseline orientation determination using two geostationary satellites and analyses the applicable conditions of carrier phase interferometry. orientation determination precision is analysed in depth through both the conventional linearized method and monte - carlo computer simulation method, and the mathematical simulation results show that the linearized method has the shortcoming of fairly low elevation error analysis precision in high latitude area so as not to be very appropriate there. by analyzing the definite factors influencing orientation precision, the dissertation develops the concept of orientation dilution of precision, which uncovers the internal cause of exotic error behavior of bi - satellite orientation, and has important guiding significance for practical engineering applications
本文系統地研究了基於「北斗一號」衛星載波相位干涉測量原理實現地球靜止雙星定向的相關技術,主要研究成果包括以下幾方面:首先,建立了利用兩顆地球靜止軌道衛星進行短基線定向的數學模型,分析了載波相位干涉測量的適用條件;採用傳統的線性化解析法及蒙特卡洛隨機模擬法兩種途徑對雙星定向的精度進行了詳細分析,數學模擬結果表明在高緯度地區線性化解析法由於俯仰角誤差分析精度略有下降而不太適合;在分析定向精度確定性影響因素的基礎上,提出了雙星定向精度衰減因子odop的概念,揭示了雙星定向誤差特殊表現的內部機理,對實際工程應用具有重要的指導意義。The angular distance north or south of the earth ' s equator, measured in degrees along a meridian, as on a map or globe
緯度地球赤道北或南的角距離,例如在地圖或地球儀上沿著子午線用度數測量Grey correlation analyses show that at the time axis, the factors influencing the diversity of plants strongly are primary productivity, annual precipitation, relative humidity, mean temperature in january, and potential evaporation etc. the spatial distribution pattern of terrestrial vertebrates including mammals, birds, reptilians and amphibians were studied with methods similar to those for plants. 7 d
通過d以排序表明, d以第一軸與多個環境因子均呈顯著相關,其中與經度、年均溫、年均降水量、年均相對濕度、潛在蒸發量、初級生產力呈正相關,與緯度、海拔、年均風速、寒冷指數、年均日照率呈負相關。分享友人
