At least in the domestic equity world you've got a pretty stable base that you were looking at ten years ago.
至少对于国内股市来说,当你回顾10年前的收益率,会得到一个非常稳定的基准数字
it's looking first to see am I in the base case, which I'm done. If I'm not I'm just going to reduce this to a smaller computation.
注意这个计算是干什么的,它先判断我是否属于基础事件,这个我已经做过了。
That they agree to some kind of base that's why I said that things maybe murkier in the end than we want.
然后他们就打成某种协议,这也就是为什么我说最终事情会变得更加复杂,虽然我们并不希望这样。
They also found some stockpiles of the virus from the 1950s that they still had on an Army base in Maryland,I think.
政府也在马里兰军队驻地发现了,从十九世纪五十年代储存到现在的病毒
In this case, to optimize for the best of the whole community and the whole user base and over the long term and that's important too, your long over short term.
在这个前提下,去寻求整个社会,以及所有用户的长远利益的最大化,这十分重要,我们寻求长期利益,而非眼前利益。
But all of you in this room probably remember what we technically call the base 10 system or decimal system because back in grade school or the like, you learned to count and add and subtract numbers by way of columns.
但是,在座的每一位可能都记得,这在小学的时候学的,以10为进制的系统或者十进制系统,通过数列方式学习数数和加减法。
What's happened actually if we base it in the last 25 years since the early '80s We've just had two recessions and they've been very mild by historical standards and...two--now three long expansions in between.
实际上是什么情况呢,80年代初期以来,这25年当中,我们只经历过两次经济衰退,而且在历史上算是相对轻微的,其间则是两,三次长时间的经济增长。
And as long as that smaller computation reduces to another smaller computation, eventually I ought to get to the place where I'm down in that base case.
如果我不属于基础事件,那么我需要把它简化为更简单的计算,随着计算的不断简化,最终我能分解成基础事件。
Need to get the base in. Second thing I want to do, I need to get the height, so I'm going to input a value for the height, also as a float, a floating point.
也就是输入底的值,第二件我想要做的,事情就是得到三角形的高,因此我会输入一个值作为三角形的高,同样也是一个浮点数。
And the code over here says, OK gee, if I'm in the base case do something.
如果我属于基础事件就进行一些操作,而我不是,所以往下看这儿。
It's oriented in the oppose direction and it has the complementary base pairs at each position.
它们方向相反,并且所有的碱基都是互补的
They face in the opposite direction and you could predict the properties of one from base pairing rules of the other but they're not the same.
它们是反向的,尽管你能够通过一条链上的碱基序列,预测另一条链的序列,但这两条链是不同的
At that point we're in the base case and we can unwrap this computation.
在这一步我们就是属于基础事件了,也就是说我们可以打开这个计算了。
It says, if I am in the base case, if b is equal to 1, the answer is just a.
首先解决基本的,如果b等于1的话,那么答案就是a了。
It has to do with the nature of this complementary binding between double stranded DNA and the fidelity of this base pair matching in forming stable DNA molecules.
这些特性能从根本上解释,为何DNA双链的碱基能互补配对,以及在形成稳定的DNA分子结构时,碱基互补配对为何具有一致性
That's because you have to satisfy this base pair matching in order to have hydrogen bonding in each of the struts of the ladder in order to form a stable structure.
NA双链要满足互补配对原则,以使碱基对之间,形成氢键,从而形成稳定的双链结构
