1.此资料中内容是六爻占卜术的最基础的知识;
2.我能整理此资料,并不代表我的技术高,这只是个人机缘的关系。
3.资料中的内容、观点与论坛无关。
整理此资料的目的
1.为了让不懂六爻占卜的朋友对其有所了解;
2.给想学习六爻占卜的易友一个入门的基础资料;
3.为了大家相互交流与个人卦技的提高。
资料内容简述如下:
第一部分 为占卜术基础内容,此中内容为所有占卜方法都使用的基础知识;
第二部分 为六爻占卜术的基础内容,其为六爻占卜方法专用的基础知识。
第三部分 为六爻占卜中一些常见的基础问题的个人浅见。
学习方法:
学习占卜不是一天两天的事儿,我们以六爻为例,你学会了起卦的方法,这并不代
表你就会解卦了,有的人学习了十几年,几十年也没有看到门,可是有的人学了几个月
甚至几天就可以分析简单的卦了,有的人不服气,有的人不明白,其实这其中除了个人
的机缘与命运不同以外,还有个学习方法的问题。(以下内容为一家之言,仅供参考)
1、学习六爻占卜术,首先要有一个稳定的心态,因为时下派系繁多,又都有各自
的一套技法,而我们这些新人也没有办法去分析那一家对那一家错,所以我建议... 阅读全帖 |

首先,institutionalized allocation of authorities在中国不存在,不是因为中国的
宪法规定了中国是一个unitary system. Unitary
system本身也可以是一种institutionalization,也是一种中央与地方权力的分配方式。
更进一步说,unitary 也不一定必然和federalism 相抵触,类似一个mutil-D的分析,中
国可以并行政治的unitary system和经济的federalism。其它的例子譬如爱尔兰。
中国之所以没有instiutionalzed allocation of authorities是因为中国缺乏一个
framework of constitutional order in which the central government can collect
taxes, allocate transfers, and enforce regulations autonomously.

l*b 发帖数: 4369 | 7 这个问题可以用基本的量子光学来证明
我们假设存在这个“叠加器”,用算符O表示
O有两路(两束电磁波)输入。方便起见,可以假设O有两路输出。
那么O可以用2x2幺正矩阵(unitary matrix)来表示,当然具体形式我们不知道。
你可以算一下,对于任意输入(|E1*a, E2*b>),输出的总能量必然等于输入的总能量
,每一路的输出能量必然不大于总输入能量,除非O不是幺正的。
但量子力学的基本假设是,除测量外的一切操作都是幺正的。
即使是测量,也可以通过引入更高纬度的希尔伯特空间来使得总的变换矩阵是幺正的。
扩展一下,可以假设O是一个2xn的幺正矩阵,我相信这也是可以证明的。
计算比较麻烦,咱就偷个懒吧,呵呵。
ps. 如果你能找到一个unitary matrix可以实现输出能量高于输入能量,那就厉害了。
一般unitary matrix在实际世界中总是有对应东东的。
其实我以前也从实验的角度考虑过这个问题。两个电磁波的叠加在波导里比自由空间里
更容易实现,因为不用考虑角度什么的问题。那比如说,搞个Y-Junction,然后两束光

group is unitary or not by a particular representation. Say, in the spinor
representation, the generator is {\Sigma}^{u v}=i/2

you can see as u,v=i,j (spatial component) the generators are hermitian which
means the corresponding subgroup is unitary. But as u,v=0,i, t |

r****y 发帖数: 1437 | 19 For a real matrix A, its condition number is cond(A) = x, suppose
x is a very large number.
Do SVD, let A = U*S*V'. If A is (m, n) matrix, U is (m, m) unitary
matrix, V is (n, n) unitary matrix, and S(m, n) diagonal matrix and
s11 >= s22 >= s33 ...
Truncated SVD means now let A1 = U(m, k) * S(k, k) * V(n, k)', where

But does it always true that cond(A') <= cond(A)?
Thanks in advance.

A is a 3x3 matrix.
U.A.U(-1) converts A to another matrix. U(-1) is the inverse of U.
Here I need to treat A as a vector of 9-dimensional space, e.g., the basis
vectors can be matrices with only one nonzero element. An operator Q can be
defined that converts A to another vector just as U.A.U(-1) does. Apparently
Q is a 9x9 matrix.
Is there any simple way of showing Q is a unitary matrix? It seems so by my

过去一年中,大中东无疑是全球最动荡不安的地区。主要的原因是,这一地区不仅聚集

近年来大中东的社会走势
首先需要简略归纳一下大中东的近代史。除了西亚的伊朗,这一地区原来大部分是奥斯
曼帝国的领地和行省。奥斯曼帝国在第一次世界大战中解体后,英法两大列强按照各自

读经:路1:46-47,帖前5:23,来4:12 .
不信耶稣的人也说“灵魂”,不过他们所说的灵魂,是指人的“精神”。基督徒信有灵

二、二元论
二元论Dichotomy , 把人分为两部分:灵魂和身体。他们说:“灵和魂不是两件,而是
一件。圣经只有两处把灵和魂分开来说(帖前5:23,来... 阅读全帖 |
