The matrix =( xi, xjp having the e-th power of the greatest common P-divisorp of xi and xj as its-entry is called the e-th power GCD matrix on S. The matrix = having the e-th power of the least common P-multiple p of xi and xj as its-entry is called the e-th power LCM matrix on 5. We obtained the following results:(1) is nonsingular for any set S;(2) If S is an FC set, then the determined of has formula Det =Jpe(x1)...Jpe, where the function Jpe is the generalized Jordan totient function;(3) A formula of the inverse of is given when S is an FC set;(4) If S is an FC set, then |.

以_P的e次方为第i行j列元素的矩阵称为定义在S上的e次幂GCD矩阵，记为；以_P的e次方为第i行j列元素的矩阵称为S上的e次幂LCM矩阵，记为，我们得到了如下结果：①定义在集合S上的e次幂GCD矩阵是非奇异的；②若S是R上的FC集，则S上的e次幂GCD矩阵的行列式Det=J_p~e(x_1)J_P~e(x_2)…，J_p~e，其中J_p~e为R上的Jordan函数；③当S为FC集时，得到了的逆矩阵~-1的表达式；④证明了当S是FC集时，整除，即等于与R上另一个矩阵的乘积。

There are those who seem to think that by force of will they can coerce this law; that they can sow seed of one kind and by "Will Power" make it bear fruit of another, but the fundamental principle of creative power is in the Universal, and therefore the idea of forcing a compliance with our wishes by the power of the individual will is an inverted conception which may appear to succeed for a while but is eventually doomed to failure - because it antagonizes the very power which it is seeking to use.

有些人可能以为通过意志的强制性作用可以迫使这个法则进行改变。通过&意志力&，他们能够&种瓜得豆&。然而，创造力的基本原理是普遍存在的。因此，想要通过个人意志的力量使宇宙力量依从我们的愿望是一种歪曲的理念，这种理念可能会获得一时的成功，但终究会落得个铩羽而归的下场──因为这种想法与它所寻求的宇宙力量存在著冲突。
