  1. About the large deformation description, a multi - floating coordinate system is adopted. it can effectively reduce the error of discretization. this paper deals with the design of restrained variable structure control in the way of phase plane analyse, which is concise and avoids complex mathematical descriptions. a new method is promoted for flexible spacecraft control by describing flexible spacecraft dynamics equations as t - s fuzzy model and designing a pdc fuzzy controller

    將撓性航天器姿態動力學方程描述為t - s模糊模型為撓性航天器控制提供了新思路;模擬結果表明，基於t - s模型的pdc模糊控制器能滿足撓性航天器大角度姿態機動的精度要求，並能有效抑制帆板振動，具有一定的智能性。
  2. However, for small span - to - depth ratio coupling beams are counter flexural deep beams restrained at their two ends and points of contraflexure at the center of the span, the rules of their carrying forces and deformation are not like common deep beams

    但是，小跨高比連梁屬于兩端被約束，反彎點在跨中的反對稱彎曲深梁，其受力和變形規律不同於一般深梁。
  3. The result showed that plastic deformation during pre - strain played an restrained role on the growth of martensite ( especially in the direction of lath width ) and increase the nucleation rate indirectly ; the elastic energy induced by plastic deformation restrain the transformation of primary martensite but accelerate the transformation of after martensite

    實驗結果表明：預應變過程中造成的塑性變形對馬氏體生長（尤其是寬度方向）有約束作用，起間接提高馬氏體形核率的作用，所儲備的彈性應變能對初生馬氏體的轉變有抑制作用，但對繼生馬氏體的轉變卻有促進作用。
  4. For all long, however, they have been divided up in routine design that is taken at large by engineers, i. e., the rigidity relation and deformation correspond thereof are not considered so that the deformation and displacement from foundation are neglected, which will result in errors neglecting the restrained function to the warp of foundation due to the rigidity of the upper structure and the secondary stress of the upper structure because of different settlement from the foundation

    而長期以來，工程界普遍採用的方法是將上部結構、基礎以及土體分割開來，不考慮各部分之間的剛度聯系和變形協調，忽略了基礎的變形和位移，從而忽略了上部結構剛度對基礎翹曲的限製作用，以及基礎的差異沉降對上部結構引起的次生應力，因而在安全性和經濟性方面都存在缺陷。
  5. Early age cracking of concrete has re - emerged as an important issue all over the world in recent years. the stress, due to restrained volume change related to thermal deformation and shrinkage in the early age concrete, is the main driving force for the deleterious cracking in the construction stage. during the development of the stress, creep, a very important property of concrete, is always developing. creep contributes to 40 ? - 50 ? reduction of the elastically induced stress in the restrained specimen. ring test, a qualitative test, can provide information to assess the potential for cracking of different concrete. an overview of ring test developed in recent years and mechanism of uniaxial tensile creep test is described in this paper at first. then, an innovative test equipment based on ring test is outlined

    近年來混凝土早期裂縫問題再次引起全球工程界的廣泛關注.早期混凝土由於體積變形受到約束而產生的應力是導致混凝土開裂的主要因素.在混凝土應力發展的同時，混凝土徐變也在同時發生著變化.有研究表明，徐變能減少40 ? - 50 ?的早期應力.圓環試驗是用於定性評價混凝土材料抗裂性能的試驗方法之一.本文首先分析了圓環試驗和單軸拉伸徐變試驗的原理，創造性地將圓環試驗用於測量早期混凝土的干縮徐變，並設計了試驗方案
