The main achievements could be summarized as follows.1. The basic stress-strain characteristics and related physical mechanisms for sands under cyclic rotation of principal stress axes were investigated based on three kinds of drained tests including fixed principal stress axes, cyclic rotation of principal stress axes with magnitudes of principal stresses kept constant, and cyclic changes of principal stresses in both their axes and magnitudes. The main deformation behavior of sands with inherent anisotropy under cyclic rotation of principal stress axes with magnitudes of principal stresses kept constant was obtained in the following.

The plastic deformation induced due to cyclic rotation of principal stress axes alone can be in the same magnitude as that due to shear with fixed principal stress axes. 2 The volumetric strain due to shearing of cyclic rotation of principal stress axes is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. The former is characterized by its reversibility and is independent of past shear history, the latter by its irreversibility increases with the increase of cycle number yet its increase rate decreases with its accumulation. 3 The obvious non-coaxiality between directions of the principal stresses and principal strain increments is found and its degree depends largely on the change of shear stress component. 4 The intermediate principal stress has considerable effects on the deformation behavior of sands in the condition of cyclic rotation of principal stress axes. The accumulation rate of the irreversible dilatancy component increases with the increase of the intermediate principal stress parameter.
具有初始各向异性的砂土在纯应力主轴循环旋转排水条件下的主要变形规律为:①纯应力主轴循环旋转可产生与应力主轴固定单调剪切处于同一数量级的塑性变形;②纯应力主轴循环旋转引起的剪切体变包含可逆性剪切体变分量和不可逆性剪切体变分量两部分,其中可逆性剪切体变分量在一周内可完全恢复,基本与应力历史无关;不可逆性剪切体变分量随循环周数的增加呈单调增加,且增加速率随其自身累积值的增大呈减小趋势;③应变增量主轴与应力主轴之间的非共轴现象显著,且在一周内具有分段性;④中主应力对应力主轴循环旋转条件下砂土的变形特性有重要影响,不可逆性剪切体变分量的累积速率随中主应力系数的增加而增加。

The degree and direction of rotation greatly affect the students' performance ; the passing rate of 90 degree items is better than that of 180 degree items , the passing rate of 180 degree items is better than that of 360 degree items, and the passing rate of right-rotation items is better than that of left-rotation items. Furthermore, handedness also affects the students' performance; the performance of right-handedness is better than that of left-handedness; right-handed students show an significant advantage over left-handed students on the items of left rotation, but no significant advantage on the items of right rotation.
四、空间旋转游戏经验的多寡,与学童的测验表现有著高度的正相关;而二度空间旋转的表现显著优於三度空间旋转;又旋转角度与旋转方向均显著的影响学童的表现,旋转角度愈大,答对率愈低,向右旋转试题优於向左旋转试题;另外,手利亦显著影响学童的表现,右手利优於左手利,右手利学童在向左旋转的测验表现上,显著优於左手利学童;但在向右旋转试题上,则无显著差异。。
