Among these new materials, polythiophene is of particular interest because both its doped and undoped species display a great chemical and electrochemical stability in air.

作为第一种无论其P掺杂态还是去掺杂态都具有良好的环境稳定性的导电聚合物，聚噻吩更是人们注目的焦点。

It has been proved that light scatter in KDP crystal aggravated when pyrophosphate was doped into the growth solution,which distributed ununiformly in prism and pyramidal sectors of KDP crystal.

掺杂焦磷酸的情况下降温生长了 KDP晶体，采用激光层析法对晶体的光散射现象进行了观察，掺杂后晶体的光散射现象明显加剧，晶体的锥面、柱面和椎柱交界面处的散射点密度并不相同，其原因在于焦磷酸对KDP晶体的锥面和锥面的影响不同。

It is also shown that the C atoms prefer the apexes of the rings, which does not change the frame structures of the B clusters.

碳原子作为杂原子倾向掺杂于团簇的顶点位置，它的掺杂不改变硼团簇的主体结构。

The result showed that the pre pared doped polypyridine was irregular granule with 0.1~0.6 μm granularity. The electrochemical performance of H3PMo12O40 and polypyridine could be manifested. The product possessed definite thermostat-bility. Polypyridine was decompounded at temperature above 511℃.

结果表明，制备的掺杂态聚吡啶形貌为0.1~0.6μm的不规则颗粒，能表现出杂多酸和掺杂态聚吡啶的电化学行为，并具有一定的热稳定性，聚吡啶在511℃以上分解失重。

The barrier layer is removed, and the walls of the trench are etched in a manner that etches the lesser doped regions of the substrate at a higher rate than the higher doped regions of the substrate to widen and lengthen the trench and to form rounded corners at the intersections of the walls of the trench.

除去阻挡层，并以比衬底的更高掺杂区域更高的速率蚀刻衬底的更低掺杂区域的方式蚀刻沟槽壁，将沟槽加宽和加长并在沟槽壁的相交处形成圆角。

The concentration of the gas could be achieved by measuring the change of the conductivity. In the experiments, the gas sensor was prepared by spreading the water solution of carbon nanotubes between the interdigitated Au electrode, which was splashed on alumina. In this paper, three methods, such as mixing palladium and copper chloride, deoxidizing palladium and copper by chemical and electrochemical means, were used to doping palladium and copper in multi-wall carbon nanotubes.

实验中我们采用单壁和多壁纳米碳管作为敏感材料，在叉指金电极间涂布纳米碳管悬浊液作为气敏膜，用于有机挥发物如甲醛、苯、甲苯和二甲苯的检测，并着重研究了掺杂氯化钯和氯化铜盐溶液、化学和电化学方法掺杂钯和铜金属颗粒对多壁纳米碳管传感器的气敏性能的影响。

But so far as the doped quantity of MoOs less than 5%, the abrupt electrical resistance change of the doped film still can reach 2 orders of magnitude, and commonly cant affect its application, so it is hopeful that temperature of the abrupt electrical resistance change can be reduced to room temperature scope.

不过只要MoO3掺杂量不高于5％时，掺杂薄膜的电阻突变仍可保持2个量级以上，一般不影响其使用功能，因此有望使电阻突变温度降至室温范围。

Secondly, the energy band structure of codoped-TiO2 shows that an acceptor level and a donor level present inside the band gap, and an electron on the donor level passivates a hole on the acceptor level, so the systems still keep semiconductor character and enhance the separation of electron-hole pairs excited by photo irradiation.

另外， V： N共掺杂TiO2的能带结构表明：导带底下方施主杂质能级上的一个电子刚好补偿价带顶上方受主杂质能级上的一个空穴，使掺杂后TiO2材料表现出半导体的显著特征，这有利于电子—空穴对的分离，提高量子产率。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
