The paper reviews the development in the analytical theory of mechanical behavior of composites, pointing out the problems existed, presenting creatively the concept of yarn state, solving the descriptive problem of perform structure of any woven composites and laying the foundation for predetermining the elastic behavior of 3-d woven composites with computer. On the basis of yarn state, the relative cross section deformation theory is introduced, the yarn cross section deformation is studied, and the experiential formula is described in the paper on the basis of experiment. The crimping state of yarn is studied, the classical "straight warp view"is modified, and the crimp height value of crimped yarn is studied. At the same time, with shrinkage rate sine method, the paper proposes the idea which imitate the shape of crimped yarn. With the third power template curve, the paper describes the microgeometry structure of fabric, finding a brief and precise approach for the calculation of mechanical behavior of composites.
本文回顾了复合材料力学性能分析理论的发展,指出了存在的问题,创造性地提出了纱态概念,解决了任意结构机织复合材料预制件结构表征问题,进而为用计算机预报三维机织复合材料的弹性性能打下了基础;基于纱态概念,提出了相对截面变形理论,研究了纱线截面变形情况,在实验的基础上给出了纱线截变经验公式;研究了纱线屈曲状态,修正了传统的&地经纱直线论&,提出了以纱线缩率研究屈曲峰谷值的思想,同时以三次样条曲线拟合了纱线的卷曲形状,较好地描述了织物的细观几何结构,为复合材料力学性能的计算找到了一条既比较简便又比较精确的途径。

In the second study, interpersonal and social rhythm therapy was 1 of 3 intense psychotherapies that resulted in better outcomes than collaborative care, in a 1-year randomized study that was part of the Systematic Treatment Enhancement Program for Bipolar Disorder trial (Miklowitz DJ et al. Arch Gen Psychiatry 2007;64:419-426). A total of 293 outpatients with bipolar I or II disorder and depression treated with protocol pharmacotherapy were randomized to up to 30 sessions of intensive psychotherapy with 1 of 3 methods — interpersonal and social rhythm therapy, family-focused therapy, or cognitive behavior therapy — or to 3 sessions of collaborative care treatment. Compared with patients treated with brief collaborative care, patients receiving intensive psychotherapy attained remission of depression within a shorter time.

In this project, the selection criteria of matrix and reinforcement for obtaining composites with high strength and toughness are determined. The as-cast and aged microstructures of composites reinforced with particles of different strength are observed, and their metallurgical conditions and stabilization mechanisms are analyzed. The aging precipitation behaviors and mechanisms are studied. Some characteristics of nano-materials (micro-distortion areas) are found in 150nm- Al2O3p/Al composites and their formation mechanisms are expatiated. The "flexible" restriction to the deformation of the matrix by low strength AlN particle is observed by in-situ TEM and SEM techniques, and the mechanisms of its resist on cracks propagation and its contribution to composite strength are revealed. The high temperature deformation behaviors of Al2O3p/Al composites are studied. A rare-earth coating is established on sub-micron Al2O3 particles, leading to an improvement in wettability between coated Al2O3 and liquid aluminum and a decrease in infiltration pressure. The strength and ductility of coated particles reinforced composite are also increased. The interfacial characteristics, bonding structures and their formation mechanisms are studied, and the crystal orientation relationships between reinforcement particles and aluminum matrix are investigated. Finally a lighter composite with better balance of strength and damping properties is reinforced with hollow ceramic microballoons of ultra-lower strength.
