The initial state of the consolidated specimens can be classified into dilative and contractive in the light of the soil state relative to the critical state line . the failure mechanisms of both dilative and contractive soils under the penetration of rainfall are analyzed 根据斜坡土体状态在临界状态线的相对位置将土体分为剪胀和剪缩两种类型，并对这两种土体在暴雨条件下的破坏机理和破坏过程进行了分析。

With the improvement of the living standard in our country , the incidence of arterous stenostic and dilative diseases are increasing steadily . in the recently forty years , with the research and development of vascular prostheses , the replacement and bypass of arteries with textile vascular prostheses has proved very successful in clinic operation 在我国，随着人民生活水平的提高，动脉狭窄性疾病和扩张性病变的发病率也不断上升，近四十多年来，由于人造血管的出现和发展，用外科手术治疗血管疾患，已成为一种常规临床手术。

The following is the main achievement in this paper : first , to binary image , we proof there are some relation between morphological erosion , dilation and perception model , and generalize the original binary erosive and dilative operation . as a result , we present the concept of degree morphological operation and establish the binary morphological model based perceptional structure 针对二值图像，证明了数学形态学腐蚀、膨胀运算与感知器模型的关系，并进一步对传统的二值腐蚀、膨胀运算做了推广，提出了程度化形态运算的概念，建立了基于感知器结构的二值形态运算模型； 2
