According to the test results given, choosing bilinear symmetry circulation restorable force model and using equivalent linearization method, this paper analyzes the dynamic responses of a single frame with foundation isolators made of flexible beam dampers and rubber bearings. 本文依据已有的试验结果,采用双线性对称循环恢复力模型,用等效线性化方法分析了具有基础隔震装置的门式框架的动力反应。
Symmetry operations are geometrically defined ways of exchanging equivalent parts of a molecule. 对称操作几何上定义为交换分子中等价部分的方式。
The problem of phase retrieval for non-axial symmetry wave-front is translated into general spherical wave-front retrieval based on equivalent diffraction model. 通过建立等效衍射模型,将非轴对称衍射光场的相位恢复问题转化成一般球面波相位恢复问题。
Another form of the symmetry, T-duality, holds that small and large extra dimensions are equivalent. 另一个对称形式为「二象性」让小的和大的额外维度等价。
So the groups should also be bilateral symmetry. According to this principle, 8 possible grouping types are proposed for the designer to choose, and the equivalent models of different grouping types are modeled. 3. 分区应遵循左右对称的原则,依照该种原则,本文提出了8种可能的分区型式,以供设计者选型。
