When I call this class definition, it calls init, init and I give it an x and a y value.
我说过,当我们,调用这个类的定义的时候,它会去调用。
Because if we recognize that there are things in the world which have intrinsic value and importance and what we call beauty.
因为如果我们承认世界上有这么,我们称为“美“的东西,其本质上就无价且珍贵。
And this is given the value the notation Avogadro's number we call it.
那个值的符号为,我们把它叫做阿伏加德罗氏数。
What is the present value of that? Well, the first-- each payment we'll call a coupon-- so it pays one pound one year from now.
那么它的现值又是多少呢,首先,每一次支付的数额称为一个券息,从现在开始每一年都要支付一英镑
And then I'll create this function, d1 this distribution d 1, which will, whenever I call it, give me a random, a uniformly selected value between minus and plus volatility.
然后我会创建这个函数,这个概率分布,每次我调用这个函数的时候,他会给我返回一个随机的,按照均匀分布,从正负浮动值之间选择的值。
Aristotle takes his stand from within politics and the regime of which he is a part. Of course we all know contemporary political scientists are not neutral. They frequently insert their views values we call them value judgments we call them.
亚里士多德的立场却是置身于,政治与政体之内,让自己成为其中的一部份,当然,我们都知道当今的政治科学,并非如此中立,他们常硬加入,他们自身的观点与价值,他们的价值判断。
At any point on the graph you can take the derivative, which will be tangent to the curve at each point, and its numerical value will be what you can call the instantaneous velocity of that point and you can take the derivative over the derivative and call it the acceleration.
在图上的任意一点,你可以进行求导,得到曲线上每一点的切线斜率,所得到的数值,即为该点处的瞬时速度,然后你再求一次导,得出它的加速度
We call that a node, r and a node, more specifically, is any value of either r, the radius, or the two angles for 0 which the wave function, and that also means the wave function 0 squared or the probability density, is going to be equal to zero.
节点就是指对,于任何半径,或者,两个角度,波函数等于,这也意味着波函数的平方或者概率密度,等于,我们可以看到在1s轨道里。
- So now if Christiana doesn't actually -- if either programmer or who's programming these little puzzle pieces, don't actually do anything with this return value, and I call, get int, she wants to hand this piece of paper -- to me, but if I don't actually assign -- no, no, I just messed up the demo.
现在如果Christiana没有-,如果程序员或谁在编写这段代码,不要对这个返回值做任何事情,我调用GetInt,她把这张纸给我,但是如果我没有赋值-,不,不,我刚才把这个演示搞乱了。
And again, a related problem that people run into is side-effects. You call a function and it returns a value, but maybe it, on purpose or on accident, modifies one of the actual parameters.
另外,一个人们常碰到的相关问题,就是副作用,你调用一个函数它返回一个值,但是故意或者无意的,它可能会修改一个实参的值。
