1.牡羊座男女…容易突然改变：恋爱幸福指数50％。
牡羊座的男女有一见锺情的倾向，牡羊座对於既定的印象是很刻板的，当他觉得一个人
讨厌，以後一定就讨厌，一开始喜欢对方，以後就会很喜欢很执著，通常牡羊座受不了
对方还是会忍，但是两个牡羊座凑在一起的时候两个都不能忍的机会就很高了，双方的
幸福指数要看双方够不够成熟。
2.金牛座男女…都保守且认：恋爱幸福指数100％。
金牛座很挑剔，但是他对於自己认定的对象就很认命，通常金牛座喜欢一样东西的时候
，他会希望对方是安定的，因此两个保守认命的金牛座，对於成家立业、买房子、存款
等等想法都是一致的，即使爱情不再，但是对於物质生活、婚姻生活以及家庭小孩…等
等都会非常尽心尽力，所以在别人的眼中看来是非常幸福的。
3.双子座男女…自我都很强：恋爱幸福指数30％。

不太理解的是－－为什么要反转MASK.
我复制了一个LAYER以后（LAYER 1 COPY)，点CURVE，点出CURVE ADJUSTMENT LAYER.然
后在CURVE ADJUSTMENT LAYER里面，可以调节相片亮度－－把中心点往上拉。 －－ 我
的理解是：这个相当于增强的SCREEN MODE。
按照你的方法，这个时候应该反转MASK.可是我按了INVERT钮（在MASK菜单下面），图
片直接就变成原始的了（ORIGINAL).不是那种象底片一样的图。
可是我如果这个时候点LAYER 1 COPY,我是可以用直接笔刷的。这样的话，相当与前面
做的都没有用。＝＝＝ 我肯定是什么地方还是没有做对。
要是搞清楚原理，会更容易理解一些。
用CURVE ADJUSTMENT LAYER是让用笔刷的时候更好的选择需要处理的地方？
用MASK是为了将笔刷处理过的地方作用到原始的图片上去？－－要是直接在LAYER 1
COPY上用笔刷，将来两个图（这个图和原始图）整合不到一块去？
不好意思，太笨了。 |

D7000 ADC很强悍啊，基本没有引入noise
Jagged curves, like the D3S show evidence of a separate amplifier for
intermediate ISO.
Straight curves, like the D7000, show evidence of being dominated by
photosite read noise.
Curved curves, like the D90, show evidence of being dominated by ADC read

生活习惯、待人接物和人品这些容易造成分手理由的除外
婚姻市场男女都有curve，随着心理成熟、工作稳定上升，到了peak之后随着衰老下降（恋爱市场另外的curve，对成熟性
和工作这些要求不如婚姻市场高，所以20岁的女孩在恋爱市场上坐标很高，但在婚姻还要等几年才到peak）
这个curve对女生残酷
男人的peak比女人晚5年
但对学业事业，多数行业对女生不会更照顾，压力太大
纯理论上，不谈感情，如果不想找比自己大很多的男人，女生找在curve上比自己稍微低一点儿的男生，一段时间以后重
合，比较利于婚姻稳定。 |

Let A be (0, 0) and B be (0, 1) on the X-Y plane. If we trace the curve
joining A and B
at a uniform speed, the curve can be represented as a vector-valued time
function
(x(t), y(t)). Without loss of generality, assume point (x(0), y(0)) be A, and
point (x(1), y(1)) be B. That is, it takes one second to trace the curve from
point A to B.

Let us not give up, since we have alreadly made considerable effort. With
exchange of ideas, we should be able to solve the problem, if it is only
high-school level. It perhaps only takes a clever trick to prove it.
I found this problem indeed interesting and amazing. Notice that a curve has a
parallel segment of length x is
equivalent to that upon shifting the curve to the right (or left) by x, the
new curve and orginal curve must intersect.

Y是luminescence， X是浓度。curve的方程是log10(Y)=a+b*log10(X)
Y是机器直接读的，所以我可以直接算出log10(Y)。但是curve做的不好，所以a和b的值不可靠。
但是
目前我只想知道样品间的浓度是否有差异，而具体的浓度数值不重要。
1）如果我用t或者ANOVO之类确定log10(Y)间有差异，是不是可以说log10(X)也有差异？因为是

2）Log10(X)有差异，那X之间有差异么？这是我比较不确定的地方。

if you draw two curves to represent the border of the universe over time, the distance between
the curves to represent the size of the universe, an accelerating univserse generates

试想，在score 50% percentile的时候 对应 一个response%， 也就是roc里面的TPR
假设这个值是 t50, 那么这个点在你的curve上是 （0.5，t50)
下面让我们来看看，这个点换成ROC会在哪里。
假设你的score比较好，response都push到前面，所以导致FPR在你这个score 50%的时
候小于0.5 （因为TP过多挤在前面）。
所以这点就变成 (<0.5, t50)
看，这点到左边了，所以整条ROC应该是会包住你的这个curve，所以ROC的AUC一定大于
