Elasticity in a system or component of a system (I'll use software as an example, since I work with IBM WebSphere eXtreme Scale every day) implies three specific degrees of freedom

系统或系统组件中的弹性（我将以软件为例，因为我每天都与 IBM WebSphere eXtreme Scale 打交道）暗示三种特定的自由程度

Or molecules. E rotational is, now it depends how many rotational degrees of freedom there are. If I've got a linear molecule, there are only two.

转动能E是，它取决于有多少转动自由度,如果我有一个直线形的分子，只有两个转动自由度。

As you study these Chi Square graphs, note that the shape of the probability functions change when you vary the degrees of freedom, or df, in your experiment.

当您研究这些X平方分布图时，请注意，当您在实验中改变自由度(即df)时，概率函数的形状会改变。

Worn over the legs with a harness that reaches up the back and around the shoulders, X1 has 10 degrees of freedom, or joints -- four motorized joints at the hips and the knees, and six passive joints that allow for sidestepping, turning and pointing, and flexing a foot.

That's a lot of fast number-crunching: Microsoft figures there are something like 10 to the 23rd power "degrees of freedom, " or possible positions, for a human body.
