酉陽作為西南少數民族自治縣，區內自然條件差、經濟落後、水土流失嚴重，屬典型的水土流失型生態脆弱區，加之該區生產手段落後、經濟結構單一、而人口增長過快，導致人地矛盾尖銳，陡坡耕作、過度開墾，使生態環境加速惡化，因此，酉陽自治縣土地資源可持續利用可以作為西部水土流失型生態脆弱區的一個縮影。Before september 18 ( superscript th ) incident, " life weekly " paid attention to japanese aggression against china with keen insight and deeply analyzed the reasons for japanese invasion of china : many factors such as japan ' s economy, politic and culture, which " life weekly " regarded as internal reasons for japanese aggression, while it held that the weakness of china was an inportant external reason for the invasion of japan

結果表明： 1 ）同頻層神經元之間或者非同頻層之間神經元之間存在相互作用，這種作用既有相互抑制（ 18對，佔81 . 8 ） ，也有相互易化（ 4對，佔18 . 2 ） ，且同頻層神經元之間的相互抑制作用較非同頻層神經元之間的相互抑制作用要強； 2 ）神經元對低刺激強度反應時，所受到的相互抑制作用較強，隨著聲刺激強度加大，抑制作用逐步降低（ p 0 . 001 ， anova ） ； 3 ）對閾上10db放電率抑制百分比進行的分析顯示，配對神經元之間的最佳頻率差越小，相互抑制作用越強（ r = - 0 . 545 ， p = 0 . 0006 ） ； 4 ）配對神經元之間通過相互抑制作用可表kx碩士學位論文waiaster 』 sthesis現出調諧銳化作用，該作用的效率與頻率有關， bf處的銳化作用較低，偏離bf時其銳化作用逐步加強； 5 ）頻率銳化作用的效率與bf差有關，隨著配對神經元之間的bf差擴亢q10 ， q30值的變化逐漸減小，其變化百分比與配對神經元之間的頻率差存在明顯相關； 6 ）配對神經元之間的相互易化作用不僅表現在放電率增加上，也表現在頻率調諧曲線的擴寬，即頻率響應范圍擴大。Firstly, the paper introduces the development and application of computer graphics & image technique, discusses the principle and method of cg and digital image processing, such as matrix of the graphic transformation, homogeneous reference frame, sampling and quantization of the image, file format of the image, template operation, etc. secondly the paper introduces the purpose and method of image enhancement processing, explains the each occasion of those methods such as threshold transformation, smoothing processing, sharpening processing, analyzes and contrasts the processing results of object image. thirdly, the paper introduces the method of mathematics morphologic, edge detection and thinning processing, attains character description of image and character dots of the contour. fourthly, the paper processes the coordinate transformation to character dots and basic splines fitting, imports correlative condition to devise meshing line and meshing track

第二，法律框架的構造過多地依賴于以國內機制來協調跨國公司法律問題上的矛盾，不僅妨礙了統一法制的構築和推進，而且使跨國公司法律問題更加復雜，使得矛盾更加尖銳化。第三，對跨國公司在現代國際經濟生活中的作用存在認識上的分歧，制約了跨國公司的國際法制的統一化發展。總而一言之，只有運用現實主義的觀點，準確把握跨國公司在現代國際經濟生活中的積極、消極作用，才能為其國際法制的合理構築創造理念卜的根據。Abstract : emulsion " s effect mechanism on impregnated diamond bit " s self sharpness is presented through analyses of experience and testing data in drilling with impregnated diamond bits in hard and compact ground
