The mutation, contrast and heterogeneity of ecological interface between oasis and desert ecosystem increased. rare natural or non - regional mosaic of patch show obvious sensitivity to spatial scale, the change ratios of theirs area and perimeter are greater than large patch
同時通過測度敏感性檢驗，表明在尺度變換中，稀少的自然或隱域性斑塊鑲嵌體對空間尺度敏感性大，面積、周長等變化率大於大斑塊，隨尺度中度干擾則合併成較大的斑塊，隨尺度強烈干擾或隔離加強后最先消失。 -
In order to study the thermal performance and residual stress of microelectronic subassembly, in this paper, a newly optical interferometry method for 3 - d displacement measurement is developed based on wavefront interference theory. in which the moire interferometry provide the in - plane displacement, but the system is different from the conventional interferometry, the system applies the double diffraction of the specimen grating, the in - plane displacement sensitivity is a factor of 2 higher than that of the conventional moire interferometer. twyman / green interferometry method for out - of - plane displacement measurement is adapted, the advantages of the optical set - up are structure novelty, and the fringe patterns of the displacement fields shown high contrast and spatial resolution
為了詳細研究試件的熱變形特徵以及殘余應力的影響作用，本文在波前干涉理論的基礎上，設計了一新型三維光學測試系統，該系統的平面位移測試基於雲紋干涉方法，但採用與普通雲紋干涉不同的光路系統，利用試件光柵和平面反射鏡組形成的兩次衍射，使平面位移干涉條紋倍增，測量靈敏度是普通雲紋干涉的2倍，系統的離面位移場測試採用泰曼格林干涉光路。
