  1. The main purpose of this paper is to study crack growth rate of a class of nonlinear viscoelastic materials under the condition of constant load and small - strain. in this paper : the new test program is raised by referencing the existing test programs and by our trial and error ; in the new test program, facilities involved in the nonlinear viscoelastic crack tests are relatively few, the test process is relatively simple and the data obtained from the experiments are credible. on this basic, the calculation of j integral of nonlinear viscoelastic double cantilever beams specimens and the parameter of fracture work of corresponding nonlinear viscoelasticity are derived

    具體成果包括： 1 、證實了雙懸臂梁試件用於非線性粘彈性裂紋擴展實驗研究的優點：雙懸臂梁試件在實驗中能觀測到的擴展過程持續時間比較長，在計算j積分時，計算方法簡單； 2 、得到了改性聚丙烯材料用於非線性粘彈性裂紋擴展實驗的兩種有效的試件構形和相應的試件尺寸；採用不斷改善夾具的方法使得加載穩定； 3 、經過連續四個多月的時間得到了一組有用的實驗數據； 4 、得到了裂紋長度與時間的關系、裂紋擴展速度與時間的關系、裂紋擴展速度與裂紋長度的關系。

  9. At the same time, according to the excellent capability of ip curves, we study fitting and description of objects, determination of invariants of objects, symmetry detection and recognition of objects based on ip curves. in all, the main contributions in the dissertation are as follows : ( 1 ) a method of determining automatically the scale of the multiscale edge detection is proposed based on the variant distance of the variogram function, and a method of segmenting texture images is also presented. the variograin values are taken as stochastic and structural properties of texture images and variant distance is taken as the size of image window
