So if now I hang on it a mass of one kilogram, I can calculate the period of one oscillation, and one over the period F is the frequency F, and I believe that is something like 38 hertz.
如果在上面,悬挂1公斤物质，我能够计算出,振荡的周期，1除以周期,等于频率，我相信,等于大概38赫兹。
Such as kilogram of mass unit , Kelvin of thermodynamic temperature , Joule of energy unit , Ampere of electric current intensity and Newton of force unit and so on?
比如，质量单位千克，热力学温度开尔文，能量单位焦耳，电流强度单位安培，力单位牛顿等。
The human brain is a 3-pound (1.4-kilogram) mass of jelly-like fats and tissues-yet it's the most complex of all known living structures.
人脑是一堆大约重达3磅(1.4公斤)的啫喱状物质，就像脂肪和其他组织一样，目前它还是已知的身体结构中最复杂的。
