实验表明，在阻挡层式光控载流子开关器件的设计中，要实现完全意义上的ON-OFF全开关，必须满足两个条件：一是作为光控载流子开关层的二芳基乙烯材料，必须具备足够大的开环态和闭环态之间的HOMO能级差异，在一种状态下有利于载流子的传输，在另一种状态下则可以顺利地阻挡载流子的传输；二是器件的各材料层之间的能级一定要互相匹配。

本文主要研究了量子纠缠态的制备及纠缠态在量子通信中的应用，包括远程制备光子-光子纠缠态，产生和浓缩多原子纠缠态，利用纠缠态进行远程克隆以及通过腔QED实现多组份密集编码的方案。

As we know, if one mode of the electromagnetic field is prepared in a squeezed state, the quantum fluctuation of one of its quadrature components can be lower than that of the corresponding part in a coherent state and that of the other is higher, and we can tune the signal-to-noise ratios of its quadrature components: one of the quadratures can be used to absorb the quantum-mechanical noise, while the other one serves to transmit an extremely well-defined signal.

由于压缩态中光场某一分量的量子涨落可以小于相干态中的量子涨落，即可以小于量子涨落的最小值，因此可以用来改变信号传递的信噪比，从而在低噪声通讯、弱信号探测、高精密测量等方面具有重要的应用前景。

State regime construction means that state power collapses traditional local power structure, and sets up new political system and political culture, in order to realize regime's bureaucratization and rationalization. So the state regimes construction includes three respects: The first is state bureaucracy system construction, modern state regime depends on this system to promote state power.

国家政权建设是指国家权力不断瓦解传统地方权力结构，确立新的政治体制和政治文化，实现政权的官僚化和合理化的过程，它包含三方面的问题：一是国家官僚体制建设，现代国家政权是以官僚体制为工具来推行国家权力的，国家政权在官僚体制建设中形成新的规则和运行秩序，体现了新的国家与社会关系；二是国家能力建设，国家能力是指推行国家权力应具备的社会经济基础；三是合法性建设，将政治权力的行使变成"合法"权威，使国家权力的推行不至遭到民众的抵抗。

Transfers state-owned and the collective property right completely has not entered the market, the minority unlawful element seizes the opportunity the camera operation, receives the bribe, the underestimate sells cheap state-owned and the collective property; The state-owned property right management level from sells buys, even uses the illegal method to fictionalize empty increases the cost and the debt, shifts the hideaway property, embezzles state-owned and the collective property; Inside and outside some units colludes with, underestimated sells cheap the state asset; By expense and so on pre-buckle staff economical compensatory payment names pull down the property right transfer price, finally lets let only then free hold this part state-owned and the collective property.

资本家和贪官污吏勾结窃取国有和集体资产主要有"四大暗道"：转让国有和集体产权没有完全进入市场，少数不法分子乘机暗箱操作、收受贿赂、低估贱卖国有和集体资产；国有产权管理层自卖自买，甚至利用不法手段虚构虚增成本和债务，转移隐藏资产，侵吞国有和集体资产；一些单位内外勾结，低估贱卖国有资产；以预扣职工经济补偿金等费用的名义压低产权转让价格，最终让受让方无偿占有这部分国有和集体资产。
