Applying the information extracted from numerous hydrographic data of field trials collected by h / hcs - 017, the first set of multi - beam swath bathymeter developed in china, a series of mosaic techniques have been carefully studied in this thesis, including digital terrain model building, statistical error analyzing, hydrographic data mosaicking as well as tides correction and projection of the earth coordinates. finally, standard digital sea - charts and three dimensional seafloor images are successfully developed that are consistent with hydrographic surveying principles
本文利用我國第一臺h hcs ? 017型條帶測深儀的測量數據進行拼圖技術的研究，主要研究的內容有：利用分帶原理對深度數據進行潮汐修正，得到瞬時海面的深度數據；對測深數據進行誤差分析處理，去除野值；將多波束數據進行坐標變換及投影轉換后構建數字地理模型，進而根據海道測量規范繪制標準海圖。 -
By surveying the sample plot, the relations between the stabil ity of the mountai n slope of soil preparation for planting by using explosion and other factors s uch as precipitation, terrain ， were studied. by using the method of quantitative t heory i, the interrelation between the damaged degrees of soil preparation progra ms by using explosion in low mountain area with abundant precipitation and terrain factors was systematically analysed, and the mathematical models relate d were developed. the results show that the precipitation in early days and the m aximum precipitation per day are the primary factors causing the soil prepara tion program damaged. the main terrain factors of the mountain slope that affect the program stability are according to their importance, slope, position and dir ection. the suitable mountain slope for soil preparation by using explosion is th e slope of less than 25
通過典型標準樣地調查資料，探討了造林爆破整地工程的坡地穩定性與降水、地形等因子的相互關系，應用數量化理論，對在有充分降水條件下的低山丘陵區的爆破整地工程損失程度與地形因子之間的關系進行了系統分析，並建立了相應的數學模型，研究指出，充分的前期降水和日最大降雨量是引起爆破整地工程損失的激發因素；影響爆破整地工程穩定性的主要地形因子是地面坡度，其次為坡位、坡向，實施爆破整地工程的地面坡度以不超過25為宜。 -
Real time seafloor tracking technique is the critical technique to ensure smooth seafloor surveying with full coverage and high efficiency. after detailed investigation on stochastic features of seabed reverberation produced by mbss systems, the author presented an algorithm and a set of relevant key coefficients for real time seafloor tracking, taking into account of characteristics of signal processing and timing sequence of the real system and introducing theorems of terrain surveying. as an achievement, a mathematical model was established based on the technique of centered filtering
海底地形實時跟蹤技術是保證多波束測深系統實現高效率全覆蓋水下地形測量的核心技術，作者通過對多波束測深系統海底回波信號統計特性的研究，依據地形測量理論，並結合實際系統信號處理的技術特點和處理時序，提出了實現海底跟蹤控制的關鍵參數及計算方法，建立了基於中值濾波技術的海底地形實時跟蹤數學模型，並開發出實時地形跟蹤專家系統，該系統經多次海上實驗驗證表明：理論正確、方案可行，取得良好效果。 -
