    文摘:以窯街三礦1500混凝土結構副大巷多層急傾斜煤巖層中復雜結構為研究對象,應用三維有限元模型,結合現場礦壓觀測結果和相似材料模擬試驗結果,對該巷道內部應力破壞敏感部位的內力和變形機理進行了系統的研究,得到了非常直觀的可視化計算結果,這對現場支護設計、維護加固和提高巖層的「凝聚力」具有重要的意義
  4. In order to efficiently improve the stability of the apparatus, a dual - optical detection circuit was adopted. to eliminate the multiple scattering effects on transmittance measurements, the range of the transmittance was limited to 70 - 100 % by adjusting the width of the light flow cell and changing the intensity of the incident light through regulating the load voltage of the laser light source. moreover, the data acquisition software was programmed in microsoft visual bas

    通過調節激光光源負載電壓改變光強度及調摘要整檢測池的寬度,消除了多重散射對透光率的影響,將透光率的變化范圍控制在滿足beer1a毗ert定律的范圍內工將溫度、溶液密度和透光率信號經模數轉換,並用microsoftvisualbasic語言編寫的數據採集軟體,實現了實驗過程中各被測量的自動連續採集。
  5. Automatic threshold choice is difficult and important to color images edge detection, first of all, on the base of human visual properties, threshold versus intensity function of human visual system are researched and analyzed, by using method of mathematic modeling and the result of saturation research, function of least color difference that can be perceptible by visual systems in detecting edge is given

    摘要自動閥值選取是彩色圖像邊緣檢測的難點和關鍵問題,首先從人類的視覺特性出發,分析了人類視覺系統的亮度感知門限函數,利用數學建模方法和色度學方面的研究成果,給出人類視覺系統對彩色圖像邊緣所能識別的最小彩色差函數。
  6. We discuss the visual information from texture image and the cause of texture distortion, and then present a simplification algorithm with texture in chapter three. the visual information from different parts of texture image is measured by color variation, and the possibility of texture distortion is measured by the unevenness of texture intensity ( the area of a triangle ' s corresponding texture divided by its area in geometric space )

    該演算法考慮了紋理扭曲的成因和紋理圖像內容對視覺的影響,用邊緣檢測的方法度量紋理圖像上不同區域對視覺影響的大小,用紋理密度(三角形對應紋理區域的大小和它在三維空間中面積的比值)的變化度量紋理扭曲發生的可能性和嚴重程度,並把這些與紋理相關的誤差度量和幾何誤差度量結合。
