In the third chapter, we adopted a model in which atomic chain is connected with two reservoir and buffer Layer. Non-equilibrium Atomistic Green's Function method is adopted to study the model. And we study the influence of reservoir and buffer layer on heat transport.

第三章，我们采用了接有热库和缓冲层纳米链模型，采用非平衡原子格林函数法来研究一维链在有热库和缓冲层连接的情况下对系统热输运的影响。

The third approach is about the concept of an ITO direct Ohmic contact structure on GaP window layer. The direct Ohmic contact structure is performed by the deposition of an AuBe diffused thin layer and the following activation process on the surface of a Mg-doped GaP window layer. The presence of this thin AuBe diffused layer yields the Be dominant metallic surface layer and significantly reduces the barrier height between the ITO and p-GaP layer. Via the modification of contact structure, not only the brightness was significantly increased but the reliability was comparable to the conventional LED without this structure.

第三个研究为一种具有直接欧姆接触在p型磷化镓窗层与氧化铟锡界面的制程方法，於本研究中并无习知砷化镓欧姆接触层的存在，我们利用金/金铍金属藉由热退火程序，使其金铍原子在磷化镓窗层表面形成具金属特性之薄膜层，降低磷化镓与氧化铟锡接触产生之接面能障；另外，该元件在氧化铟锡直接欧姆接触於磷化镓窗层下，除亮度具明显提升外，在稍大电流(20毫安培)元件可靠度测试下，亦未有明显衰减情形发生。

We show that the quantum-jump-based feedback can be used to generate steady entangled state of three atoms against decoherence.

The results show that the triplet state of the complex is more stable than the singlet one and there is a weak effect of spin delocalization in the complex.

结果表明：配合物分子的三重态比单重态稳定，电子自旋布居高度集中在两Co原子上，体系中存在较弱的自旋离域效应。

For the heteroatomic dian- ionic22- species, there are also three stable isomers: rhombus (D2h), roof-shaped (C1), and C2v structures with the rhombic isomer being the ground state.

由异原子组成的22-团簇也有三种稳定结构：菱形(D4h)、屋顶型(roof，C1)和C2v结构，其中菱形结构是基态。

To make an atom bomb we have to use uranium 235, in which all the atoms are available for fission.

制造原子弹必须用铀235，因为它的所有原子都可以裂变。那位女记者说有一个炸弹或一批炸弹可能在凌晨三点爆炸。

The wavelength of the third laser is scanned when those of the first and second lasers are fixed, through which spectra of Ba 6pns autoionization series are measured.

当固定第一和第二步激光波长而扫描第三束激光波长时，便可获得Ba原子6pns自电离态的光谱。

It is found that Kerr effect has a great influence on the non-classical photon statistics in the case of large single-photon detuning in the system.

结果表明：当单光子失谐量较大时，Kerr效应对光场与级联三能级原子非共振相互作用系统的光子非经典统计性质有较大影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
