Let me show you one more class, though about-- sorry, let me show you two more classes of algorithms. Let's look at the next one g- and there's a bug in your handout, it should be g of n and m, I apologize for that, I changed it partway through and didn't catch it.
请大家看,额,在你们的课堂材料中有个错误,应该是g,很抱歉-,我改了一部分这个错误但是没看到这里的,好,这儿的增长率,有人想猜猜么?
It's called the G-protein coupled receptor because it's a receptor, like the one shown here, that's coupled to a special molecule called a G-protein.
之所以叫这个名字是因为这种受体,就像这里展示的一样,是与一种叫做G蛋白的特殊分子偶联的
I know this is the right answer, because if I now find the acceleration, I find it's mg divided by m and I get -g as the answer for all bodies.
我知道这个等式是正确的,因为现在如果我要求物体的加速度,用 mg 除以 m,我就得到 -g,这个结果对所有物体都成立
So here in the G Minor Symphony we feel as--oh, it's so full of tension, angst,anxiety, perhaps passion, it's driving somewhere, and one of the things that's driving it is its accelerating rate of harmonic change.
在G小调交响曲里我们能感觉到,哦,音乐中充满了紧张,揪心,焦虑,甚至激情,这些感情正在向某个方向涌去,吸引它们的力量之一就是不断加速的和声变化率。
g has to be less than r for this to make sense because if g--if it's growing faster than the rate of interest, then this infinite series will not converge and the value would be infinite.
必须小于r才行得通,因为如果g比利率涨的还快,那么这个无穷序列就不会收敛,价值就是无穷了
For example, suppose you use vertical motion and you use y instead of x; and a would be g or -g; that's a particle falling down under the affect of gravity.
例如,假设在竖直运动中,你用 y 来代替 x,那么 a 就是 g 或者 -g,这就是一个受重力作用下落的质点
