In experimental modal analysis, it is necessary to measure the response data in directions of all degrees of freedom to obtain the complete mode shape information.
试验模态分析中，要获得完整的模态振型，需要在所有自由度方向都进行测量。
所有的那些自由度。
All these low energy degrees of freedom.
所有这些低能量的自由度。
You have to keep track of how many degrees of freedom there are. But that's all you have to do.
你必须掌握有多少自由度，但那就是你所要做的。
Based on the above research work, an all-position welding robot with 5 degrees of freedom is developed to improve the automatic welding efficiency and quality of spherical tanks.
在此基础上，研制成了一种5自由度的全位置焊接机器人，能对球罐内外纵缝、横缝及仰缝进行无导轨全自动焊接，达到了高效率、高质量、无人实时操作和低劳动强度。
Wealth and poverty, health and disease, culture and ignorance, Labour and leisure, repletion and hunger, virtue and vice, are all only terms for greater or less degrees of freedom.
富裕和贫寒、光荣和默默无闻、权力和屈服、强壮和软弱、健康和疾并教养和无知、工作和闲暇、饱食和饥饿、道德和罪恶，都不过是较高或较低程度的自由罢了。
