运算很简单，但前提是记下代码，否则无法完整地在头脑中使用这种方法。
The math is pretty easy, but unless you memorize the codes, you won't be able to perform the entire technique in your head.
尽管这听起来很简单，但这是一种经过验证的方法，IBMCloud环境就支持这种方法。
As simple as this sounds, this is a proven method and one which the IBM Cloud environment supports.
很显然，这种方法很糟糕，但是解决方法也很简单：永远不要将可变对象类型用作hashmap中的键。
Clearly, this approach is a pain but the solution is easy: Never use a mutable object type as a key in a HashMap.
与电系统稍有不同的是，这种方法需将机械系统结构图作适当的改形。改形也很简单，只要将串联形式的质量元件改为并联即可。
Differing from electrical system, the structural diagrams of mechanical system need the change of series combinations of mass elements into parallel combinations, which is very simple.
