Mark J. Roe A strong theory has emerged in recent years that the quality of corporate lane primaritly determines whether securities markets arise, whetl from control, and whether the modern corporation can prosper. nwehy we see weak corporate structures in to explain why concentrated ownershippe

前面说过,组合逻辑电路的输出只与 输入有关,时序逻辑电路的输出既与当前 的输入有关,又与以前的历史状态有关。 那么以前的状态在哪里保存? 存在触发器里面,触发器是逻辑电路的基 本记忆单元。 本章学习有关触发器的知识,主要是 基本触发器、D、R-S和J-K触发器

1.角动量合成的一般规则 我们在很多情况下会遇到角动量合成(即相加)的问题。在本节,我们只注意角动量合成的一般规 律,而不注意那些角动量的具体物理背景,所以我们将采用 Dirac符号。 设j和2是两个互相独立的角动量,这意思是,它们的分量分别满足角动量的对易关系,而它们 互相之间是对易的:

1.两个电子自旋的合成 设S1和S2代表两个电子的自旋,它们的总自旋是S=S1+S2,对照角动量合成的一般规则,现在 =j2=1/2,所以总自旋的大小可以取值 S=1.0. 形象地说,当两个电子的自旋互相平行的时候S=1,而当两个电子的自旋反平行的时候S=0 我们还要解决总自旋的本征态如何用各电子的态矢量来表达的问题,换句话说,也就是要计算这个 时候的CG系数

Basic antenna operation Receiving and transmitting antennas are identical: Time just flows in opposite directions. Antenna problems are solved knowing the current distribution J(x') in the antenna and using a vector potential
