Since the MASS vector functions are much faster (by a factor of up to about 30) than a repeated call to a standard library function, the resulting performance improvement can be substantial.
因为MASS向量函数要比对一个标准库函数的重复访问快很多(倍数接近30倍),所以最后得到的性能改善效果将会是惊人的。
Catholic Churches, they usually call it the Mass, but they're all referring basically to the same thing, the sharing of the bread and the wine.
天主教会,通常称之为弥撒,但其实他们指的都是同一件事,也就是分吃面包和葡萄酒。
I already introduced, as you see there length, time and mass and we call these the three fundamental quantities in physics.
我已经讲过,长度、时间、质量,它们被称为,三个基本物理量。
Likewise for mass, we will take a chunk of some material and we will call it a kilogram.
质量也是这样,我们找来一大块材料,然后称它为 1 千克
But he also realized that when they did hit something what they hit what unbelievably massive but also that that mass was concentrated So eventually, this is what we have come to call the nucleus of an atom.
碰到的一定是十分重的东西,而且那些质量,要聚集在非常非常小的空间内,这个就是我们称作,原子核的东西。
