  1. At first, double random phase encoding techniques are looked back and its improved methods are introduced in detail. in connection with characteristics of spherical wave gene and function of phase mask, one random phase encoding techniques are proposed with spherical wave based on 4f system

    本文首先對雙隨機加密技術進行了回顧,並對它的一些改進方案的特點作了詳細介紹,並在此基礎上,根據的特點和掩模在加解密中作用,提出了一種利用波照射4f系統的單隨機編碼加密的新方法。
  2. 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」衛星載波干涉測量原理實現地靜止雙星定向的關技術,主要研究成果包括以下幾方:首先,建立了利用兩顆地靜止軌道衛星進行短基線定向的數學模型,分析了載波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素的基礎上,提出了雙星定向精度衰減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。
  3. Many studies had attempted to characterize chemical weathering process by focusing on geochemisty of river particulate and sediment. the sediment geochemistry may reflect and compare with the carbonates and silicates weathering degree by introducing the chemical index of alteration ( cia ) and new sediment index of variation ( siv ) and elemental molar abundance ratio of the sediment. the one main objective of this study would provide and compare the relative weathering intensities of silicates and carbonates with the different basins

    2沉積物地化學與化學風化進程和機械剝蝕率化學風化指數與化學風化率屬于表徵化學風化作用意義不同的函數,前者為對概念反映流域巖石在原巖基礎上己發生淋溶作用的深度,主要受到了氣候的深刻影響(中國流域沉積物化學風化指數由北到南呈有規則的遞增序列,氣候對風化進程的影響掩蓋了巖性的巨大差異) ,而化學風化率含義是指單流域積巖石風化淋溶產生的離絕對總量。
