The U.N.Deputy Resident and Humanitarian Coordinator in Juba,South Sudan,Lise Grande, says the number of internal conflicts in the semi-autonomous region has risen from last year's levels.

to the n, every value in the 1 bit vector we looked at last time is either 0 or 1. So it's a binary n number of n bits, 2 to the n.
从2到n,我们上次看到的,位向量的每个值不是0就是,所以它是n,比特的二进制数,从2到。
And we can calculate that with the formula that we used, which was just n minus l minus 1 equals the number of nodes.
这个我们可以用我们以前用过的那个公式来计算,也就是节点数等于n减去l减去1
U.N.Special Representative Radhika Coomaraswamy says during the past year, a significant number of child soldiers were released by the National Liberation Forces in Burundi and more children are to be released in the Central African Republic and the Philippines as a result of active intervention by the United Nations.

So in other words, every time I merge the point that I kept emphasizing verbally there and that I'm only touching each number once, means that we have to account for the amount of time it takes to merge N which is going to be just N. Now, this is again one of these cyclical answers.
换言之,之前在做合并时,我不停地强调,对每个数字我只碰了一次,这就是说,我们要记录合并所花的时间量,也就是这里的,这又是一种循环性的答案。
"These targets are set for 2015 and are to achieve at least 90 percent measles vaccination coverage nationally and 80 percent coverage in every district, reduce measles cases to less than five per million population, reduce measles mortality by U.N.health agencies have made huge strides in reducing the number of children dying from measles.

It could have ended any number of other ways, and just so this story could end a number of ways.
它本可能以N种其它方式结尾,也正是如此这个故事才能以若干方式结尾。
And then the number of pairs at month n is the number of pairs at month n - 1 plus the number of pairs at month n - 2.
我们让第一个月的兔子数是1对,第n个月的兔子对数,是第n-1个月的兔子对数。
Whatever the n number is, with the exception of helium, helium is the oddity because there's only two elements in n equals one shell.
无论n是多少,除了氦之外,氦是个特例,因为只有两个元素,在n为1的这一层。
You have n branches on the tree and you count the number of leaves and sum them up.
一共有n根树枝,你数了叶子的数量然后把他们加起来
With respect to n, the number of moles.
对n的偏导数,这里的n是摩尔数。
psi So we're going to for psi, and before that, we're going to figure out that instead of n just that one quantum number n, we're going to have a few other quantum numbers that fall out of solving the Schrodinger equation for what psi is.
我们要讲到,但在这之前,我们已经知道了,主量子数,现在我们需要知道,其他一些,解psi的薛定谔方程,所需要的量子数。
So this line or these lines of code up here are arguably constant time steps to say if N is less than 2 in return, that it will always take maybe one step, maybe two steps, some number of fixed CPU cycles.
如果N小于2并返回,那么这些行所对应的代码,通常只需要执行一步,或者两步,具体数字与CPU周期有关。
Core electrons are all those electrons held in really tight with the nucleus in the inner shells, whereas the valence electrons are only those electrons that are in the outer-most shell, or at your highest value of n of the principal quantum number.
芯电子是那些,在内壳层被原子核束缚得非常紧的电子,而价电子只包括,最外层的电子,或者说主量子数,n,的值最大的那些电子。
This first number here gives the value of n.
这里的第一个数字是n的值。
And we can generalize to figure out, based on any principle quantum number n, how many orbitals we have of the same energy, n and what we can say is that for any shell n, there are n squared degenerate orbitals.
我们可以总结出来,在,主量子数为n的情况下,同一个能量上,有多少个轨道,我们可以说,对任何壳层,有n平方个简并轨道。
On the other hand, we've seen n that if the size of a is n, that's to say, we have n elements to choose from, then the number of possible subsets is 2 to the n.
另一方面,我们看到,如果a集合的大小是,也就是说我们有n个元素可供选择,而可能的子集的元素,个数就是2的n次方。
You count n leaves--you count the number of leaves.
你数了n片叶子...不对
n So the velocity is given by this product of the quantum number n Planck constant 2 pi mass of the electron time the radius of the orbit, which itself is a function of n.
速度是量子数,普朗克常数2π乘以轨道半径的值,它自身也是n的函数。
The other main difference that we're really going to get to today is that in multi-electron atoms, orbital energies depend not just on the shell, which is what we saw before, not just on the value of n, but also on the angular momentum quantum l number. So they also depend on the sub-shell or l.
我们今天要讨论的,另一个很重要的区别就是,在多电子原子中,轨道能力不仅仅依赖于,我们以前看到的外层,不仅仅依赖于n的值,而是与角动量量子数也有关系,所以它们也依赖于亚外层或者。
