标 题: 向亚伯拉罕显现的是圣子，与雅各摔跤的也是圣子
发信站: BBS 未名空间站 (Thu Jul 23 13:31:04 2015, 美东)
【约1:18 关于“从来没有人见过神”
耶证说如果耶稣是神的话，不是有很多的门徒见过耶稣吗？可见耶稣不是神。
解经要看上下文。您不能只看上半句不看下半句吧？原文是“从来没有人看见神。只有
在父怀里的独生子将他表明出来（约1:18）”。
原文的重点其实在后半句。因为神太大了，有限的人不可能看见无限的神。只有神自己
局限自己到有限世界，人才能看见他的“像”。所以说耶稣是“神本体的真像（希1:3
）”。如果耶证这样质疑，我不知道他们怎么看创18章。 亚伯拉罕跟耶和华交谈，他
们的新世界译本也是这样写的。想以此节经文否定耶稣的神性真是该打手板子。解释只

个神是笼统的说，没有加定冠词特指父神。包括耶证的圣经也说是耶和华在跟亚伯拉罕

This is my feeling.
Actually, such a education system is not good in my opinion.
Students are treated unequally by society since their birth
although they have to accept the fact that their birth is not equal,
some born in rich families, some born in poor families.
Students who were treated specially may still think they should enjoy
special rights after they enter society. So it's hard to make the
society relatively equal. They may |

if q is shorter than p, then q will hit '\0' first, in this case the
comparison will lead to "res = 1".
since u already checked res != 0, the case of unequal lengths is already
covered.
actually even in the 1st code, *q++ != '\0' can be replaced with q++. |

还有学统计别一叶障目，光明白一个t test就来大谈假设不假设。parametric
statistic都是基于distribution assumption，没有了这个assumption，还能叫
parametric test？至于后来发现很多test对轻度的non-nomarlity以及unequal
variance有一定程度的容忍，那是test的robustness,跟statstic原本需要符合的应用
条件并不排斥，不能因为test robust就掘弃normality assumption了。

China's disparities surpass those of the United States and Western Europe,

S_i and S_j are independent for any unequal i and j.
M = S'*S
容易知道 M 是个 KxK 对称矩阵，并且主对角线元素M(n,n)都为1。
我用matlab试验发现, K越大，M^(-1)的主对角线元素M^(-1)(n,n)也越大。
比如，M^(-1)(1,1)随着K增大而则增大。K
猜想，M^(-1)(n,n) monotonically increases with K.

The reason for this assumption is that the denominator of the F-ratio is the
within-group mean square, which is the average of group variances taking
group sizes into account. When groups differ widely in variances, this
average is a poor summary measure. Violation of the homogeneity of variances
assumption will increase type I errors in the F test (wrongly rejecting the
null hypothesis). The more unequal the sample sizes in the cell |
