Then,a new result of quantum mechanics is given:considering an arbitrary manipulation of one EPR particle,which can be modeled in fullgenerality as a unitary interaction of that particle with an outside system or ancilla,ini-tially in a pure state,we shall show that such interactions can be used to prepare all andonly those states of the joint system(two particles in arbitrary entanglement and theancilla)that yield unperturbed marginal statistics for all measurements on the anotherparticle,with which the ancilla did not interact.

首先，我们介绍了量子通讯的概念是如何被引入的；其次，我们给出了一个新的量子力学结果：制备一对EPR粒子，然后把它们分开，如果我们对其中的一个粒子进行操作，那么该操作将不会改变另外一个粒子的单独测量的期望值。

And the lattice distance expands anomalously with decreasing particle size. Using the model of long-range interaction and its cooperative phenomena altered by particle size, the size-induced cubic-tetragonal phase transition, the anomalous lattice expansion, and the change in chemical bonding characters have been well understood.

采用长程相互作用的晶粒尺寸效应模型，对钛酸钡纳米晶结构相变、晶格间距异常增加、价键性质变化等实验现象给出了合理的统一的解释；并把该模型扩展到解释与钛酸钡晶体具有不同共价性成分的氮化镓等纳米体系的相变以及晶格结构变化现象。
