We can quickly see that some of the mode shape information is strongly controlled by the exterior of the structure.
我们很快可以发现，某些模态振型信息是由结构外部极大地支配的。
When the springs supporting the beam are very soft, then the mode shape for the beam looks very much like a rigid body.
当支撑梁的弹簧非常软时，梁的模态振型看起来非常像刚体。
Finally, many complex mode shape derivatives of high accuracy can be obtained by decomposing system matrices only once.
