对整车模型进行发动机激励下的单位位移谐响应分析，根据谐响应计算结果，对发动机激励下的整车结构动态性能进行了分析和了解；

Also, harmonic analysis of the whole structure of the bus under excitation of engine was carried out, and through the results the dynamic performance of the bus excited by engine vibration was known.

好了，那就是连接在末端的向量2中的其中一个向量， 但是我想要连接向量2的两倍，因此第二个向量将同样也相左一个单位位移，向上2个单位。

Ok, that's 1 of column 2 tagged on the end, but I want it tag on 2 of column 2, so the second one will go up left 1 and up 2 also.
