We note that the structure is symmetrical and that sways represent antisymmetrical loading. 注意结构是对称的,而节点线位移表示反对称荷载。
By using Rayleigh-Ritz method, he solves approximately the optimized form of critical load and section of two-hinged circular arch in antisymmetrical buckling and symmetrical buckling state under the action of hydrostatic pressure. 利用瑞利里兹法,近似求解在静水压力作用下,两铰圆拱呈反对称屈曲和正对称屈曲状态的临界荷载和截面的优化形式。
Results show that: ( 1) the vertical dynamic stress histories are easily taken with the antisymmetrical distribution in the two sides of the symmetrical foundation; 研究结果表明:(1)模型对称基底的竖向动应力易呈反对称形式分布;
Solution of Crack Problem of an Elastic Plane under Antisymmetrical Load with Fourier Integral Transformation Method 平面弹性中反对称载荷时裂纹问题的Fourier积分变换解法
Zero-Antisymmetrical Dyadic Wavelet-Based Oil Spill Detection Method in SAR Images 基于反对称二进小波的SAR图像海洋表面油膜检测方法
For both axisymmetrical and antisymmetrical disturbances, the increase in sheet cone half-angle reduces the wave growth rate and the range of instability, and shifts the dominant wave of the disturbances to a longer wavelength. 对于对称扰动波,液膜半锥角的增大使得液膜的不稳定范围和波增长率缩小,并且将扰动波的主波向长波的方向移动。
Analysis shows that the lowest antisymmetrical mode of lamb waves A0 plays an important role in laminates, which is just the research object of the acoustic emission detection. 分析可知最低价反对称模式的信号A0在薄板中占有重要的地位,这正是声发射检测中(特别是模态声发射理论下声源定位)所主要研究的对象。
