用直流磁控溅射法研制非晶硅太阳电池ZnO/Al背反射电极

本文首先在低温(140℃)和低功率下采用Zn:Al合金靶直流反应磁控溅射法研制ZnO:A1透明导电膜.然后在单结(glass/SnO2/pin/)或双结(glass/SnO2/pin/pin/)非晶硅电池上沉积约70～lOOnm厚的ZnO透明导电膜,最后再用电阻蒸发法沉积Al电极.实验获得了较好的n+/ZnO界面,实现了ZnO/Al背电极的增反作用,使电池的短路电流增加1～3mA/cm2,光电转化效率提高1～3;(绝对效率),小面积电池效率达到9.5;.

动力学因素对液相色谱分离整体蛋白的影响

依据液相色谱分离整体蛋白的效果与色谱柱柱长基本无关的事实,研究了动力学因素对疏水相互作用色谱(HIC)分离整体蛋白的影响。首次提出了用于线性梯度洗脱条件下蛋白分离的“条件板高”(H)概念,并将其用于动力学因素对分离整体蛋白的影响的表征。分别用常用的色谱柱和色谱饼对标准蛋白进行了分离,绘制了类似于van Deemter的“条件板高”对流动相线速(u)的曲线图。发现对应于色谱柱最低“条件板高”的适合线速约为色谱饼的1/5～1/15,且色谱饼的适合线速范围也较色谱柱宽得多。据此,用装填有HIC填料的色谱饼(10 mm×20 mm i.d.)在12 min内便可完全分离7种标准蛋白。还用装填有HIC填料的色谱饼对重组人粒细胞集落刺激因子(rhG-CSF)进行了复性并同时纯化,在50 min内,仅用一步色谱法就可获得纯度≥97%的rhG-CSF,其质量回收率为39%,比活＞1×108 IU/mg。可以预计,装填极细颗粒的刚性色谱填料的色谱饼可在高负荷条件下进行整体蛋白的高速和高分离度的分离、纯化并同时复性,达到“三高”。

Darboux Transformation and Explicit Solutions for Drinfel＇d-Sokolov-Wilson Equation

A generalized Drinfel＇d Sokolov-Wilson （DSW） equation and its Lax pair are proposed. A Daorboux transformation for the generalized DSW equation is constructed with the help of the gauge transformation between spectral problems, from which a Darboux transformation for the DSW equation is obtained through a reduction technique. As an application of the Darboux transformations, we give some explicit solutions of the generalized DSW equation and DEW equation such as rational solutions, soliton solutions, periodic solutions.     

Teleportation of N-qubit W State without Bell-State Measurement via SelectiveResonant Interaction in Cavity QED

We present a scheme in which the N-atom W state is teleported byemploying the selective interaction of a cavity field with a driventhree-level atom in the λ configuration and detecting a single atom in one of the ground states. The long-lived W state is teleported from atom A to atom B when the atoms B and A are sent through a cavity successively and atom A is then detected. The advantage is that the present one does not involve the Bell-state measurement and is robust against the atomic spontaneous emission.

A Study on Determination of TI by Differential Potential Stripping Method

So far,there are many methods of determination for Ti in reference. Recently, the promotive mechanism of oscilligraphic polargraphic current is studied by Zhang, and the results indicate that polargraphic current can be enhanced highly with SDBS and TX-200. In this paper,the possibility of the determination of TI in high pure In is studied with differential potential stripping method. The good results are achieved.
