With the different loading ratio of parallel to axis and normal to axis direction, damage defects will occur bulking problem. by varying the degree of material anisotropy relative to the loading axis such as poisson ' s ratio and shear modulus, crack growth bulking strain value parallel to or normal to the loading axis is different. the parameters controlling the growth or arrest of the delamination damage are identified as the geometry and the depth of defects and radius of cylindrical etc. at last, it was investigated that the delamination damage is often induced by the tip of matrix damage under higher stress
研究結果表明:殼體筒段受軸向拉伸和內壓載荷作用時，軸向和環向載荷的比率不同，母層和子層可能發生拉伸屈曲，也可能發生收縮屈曲，或者同時發生拉伸和壓縮屈曲;母層與子層各向異性存在差異，即泊松比與剪切模量不匹配時，將使子層板的邊界上承受壓縮和剪切作用，當分層達到臨界狀態則發生屈曲，當母層與子層的各向異性差異越大，則發生分層屈曲的可能性越大;分層損傷的屈曲應變值與子層自身的彈性模量、分層子層的形狀、厚度以及圓柱半徑等因素有關。 -
Chapter 2 : using a so - called variance matrix, we studied the propagation and the focusing characteristics of the paraxial light beams. the quantities characterizing the gross features for a paraxial optical beam, such as the beam width, the divergence, the curvature radius of the wavefront, the complex beam parameter q. and the beam quality factor, are related by using variance matrix
第二章：闡述了常數折射率介質中光束的傳輸和聚焦，建立了表徵傍軸光束總的特徵的量，如：束寬、衍射發散角、波前曲率半徑、復光束參數q與變換矩陣的關系，得到了光束質量因子和變換矩陣行列式的定量關系。 -
In this paper, we consider the optimal parameter vector a of the modified incomplete gauss _ seidel method ( migs ). we prove that the spectral radius function of the iterative matrix t of migs with parameter vector is strictly monotonic decreasing with respect to a satisfying 0 e if the classical gauss _ seidel method converges for a z _ matrix. some properties of the left and right eigenvectors corresponding to the largest eigenvalue in modulus are given, too. these results are useful to find an optimal parameter for migs
目前主要的方法有兩類：一是充分利用所給矩陣a的特點，採用適當的主元素選取策略，使分解出的因子盡可能地保持稀疏性；二是迭代法。對于第二種方法，迭代矩陣的選取具有決定作用。只有選取的迭代矩陣的譜半徑小於1才能保證迭代法收斂。
