本文以重心平面安装隔振系统为例，介绍了抑制共振与减小耦联振动的设计理论与方法。
By giving an example of heart-plane-install Vibration-isolation system. This article introduces the design theory and method.
从另一个角度看，一个平面物体的重心就是,如果在重心处拿起物体，它就能完全地保持平衡。
The other way to think about it, if I had a flat object then the center of mass would basically be the point where I would need to hold it so it is perfectly balanced.
利用这种解析关系，可以在平尾相对面积和飞机重心位置的参数平面上，绘制出各种限制边界，形成所谓“剪刀图”。
Using the analytical relationship, many boundaries namely scissors sketed, could be drawn on the parameter plane of horizontal tail area and aeroplane center of gravity.
