The so made silica gel glass has quasi - inkbottle shape and median pore size distribution of 5 - 8nm which is suitable for the doping and protection of mpc molecules . mpc molecules in matrix always have a strong tendency to dimerization that can badly affect the linear absorption spectrum , causing quench of dye fluorescence and change the yield of photochemical processes . it is a vital problem that worth more attention 鉴于酞普的二聚化是影响其非线性性能和光限幅效应的重要因素，应用紫外一可见吸收光谱( uv / vis )测试技术，跟踪研究了复合体系在溶胶一凝胶转变过程中酞蓄二聚化的产生机理、主要影响因素和变化规律，提出了可能有效抑制二聚的技术途径。
By the geometry parameters analysis , it was pointed that the distance between the outside annular and the most outside annular should be required to ensure the structure ' s stiffness ; with the increase of height h between the inside annular and outside curve equation , the stiffness would be enhanced ; when the h became very big , the structure presented the linear character , so the structure was n ' t easy to yield ; the sizes of long axis and short axis had the important influence to the structure ' s nonlinear performances and with the increase of span ; the structure presented the strong nonlinear character , contrarily the structure presented the linear character 对结构几何参数分析表明，外圈与最外圈距离r的尺度应有一定要求，以保证结构的刚度；随着内圈与外圈曲线方程高差h的增大，刚度会得到提高；当内外高差较大时，结构呈现出线性特性，因此结构不易发生屈曲现象；外椭圆长短轴的尺度对结构非线性性能的影响十分敏感，随着跨度的增加，结构表现出强非线性特征，反之结构呈现线性特征。
The concept of the longitudinal strength of ship hulls has changed and advanced greatly as the study on the failure mechanism of the hull is getting deep . by taking account the failure modes of yielding , buckling and their combination , as well as the non - linear interactions between structural members , the ultimate longitudinal bending moment is defined by the moment corresponding to the point with zero slope on the moment - curvature curve of the ship hull 但随着对船舶破坏机理的认识和研究发现，在研究船体的总纵极限强度时，必须考虑构件的屈曲、屈服等各种可能的破坏模式，要考虑受压构件屈曲后及崩溃后的非线性性能的影响，要考虑组成船体的各个构件发生破坏的渐进性质和相互作用等。
