The 312 particles are held together in a nucleus by a force that involves the continuous exchange of meson-like particles called memo-ons.
12个粒子汇合与一个原子核里,连续不断的,叫做memo-ons的介子的交换给它作用力。
We have instead what's called a probability density when we have continuous random variables.
所以我们用概率密度的概念来描述,连续型随机变量的情况
Typically up till now, we've looked at things that can be done in sublinear time. Or, at worst, polynomial time. We'll now look at a problem that does not fall into that. And we'll start with what's called the continuous knapsack problem.
至今为止我们已经处理过,亚线性问题,最多也就是多项式问题,我们现在要看的问题则是不能用这些解决的,我们将要开始讲连续背包问题。
This is called the normal distribution or the Gaussian distribution-- it's a continuous distribution.
这就是正态分布,也叫做高斯分布,这是一个连续分布
