Cast-mono crystalline silicon wafers contain crystallographic defects, which can severely impact the electrical performance of solar cells. This paper demon- strates that applying hydrogenation processes at moderate temperatures to finished screen print cells can passivate dislocation clusters within the cast-mono crystalline silicon wafers far better than the hydrogenation received during standard commercial firing conditions. Efficiency enhancements of up to 2% absolute are demonstrated on wafers with high dislocation densities. The impact of illumination to manipulate the charge state of hydrogen during annealing is investigated and found to not be significant on the wafers used in this study. This finding is contrary to a previous study on similar wafers that concluded increased H or H0 from laser illumination was responsible for the further passivation of positively charged dangling bonds within the dislocation clusters.

三维地质建模是地质研究的有力工具,断层的三维建模比其他地质体建模具有更大的难度,其中一个主要难题是交切断层切割关系的处理。本文以广西珊瑚矿田为例,探讨了基于地表数据和产状数据的交切断层建模方法,采用地表断层线-剖面断层轨迹-系列断层线-断层面的技术路线进行切割断层建模,采用初始断层面-断后约束条件-交切处理-约束插值的技术路线进行被切割断层的建模,并与其他建模方法的建模效果进行对比和讨论。最终形成了如下建模方法:(1)以旋转法求取部分切割断层的错开部位约束,以平移法求取完全切割断层的错开部位约束;以断层错开部位约束、地表断层线约束及断层面边界约束为控制条件,进行断层面DSI插值,实现断层错动;(2)局部法建模、分段断层线的平移连接及过度追求完全切割关系建模可能分别引起断层面延展可控性差、断面整体偏移误差及沿走向过度延伸问题,与地质事实相悖,故本文优选采用了整体法建模、顺延连接分段断层线及遵从原有切割关系的处理方法,获得了较好的建模效果。

辽东半岛古元古界辽河群大石桥组三段地层中赋存有全球最大工业储量的菱镁矿矿床。在总结和整理已发表的辽东半岛晶质菱镁矿床地质和地球化学数据的基础上,本次研究进行了Mg和B同位素测试及研究工作,获得以下认识:①菱镁矿矿体呈北东东走向,产于大石桥组三段,但不同矿床的矿体厚度差异较大(30~300 m),菱镁矿矿体与顶、底板高镁白云岩之间以断层接触为主,常可见到绿泥石化板岩和碳质千枚岩产于大型菱镁矿矿体的内部韧性剪切面上,说明地层经历了强烈构造形变作用;②围岩白云岩与晶质菱镁矿矿石的地球化学特征基本一致,均表现为大离子亲石性元素(K、Rb、Ba、Sr等)亏损和氧同位素负漂移(δ^(18)O:-24.9‰~-11.0‰);③在经历构造形变和角闪岩相变质作用后,菱镁矿矿石仍继承有海相蒸发沉积岩的稳定同位素地球化学特征(δ^(13)C:-2.7‰~+1.6‰;δ^(34)S:+15.6‰~+23.7‰;δ^(26)Mg:-1.53‰~-0.49‰;δ^(11)B:+9.8‰~+13.4‰);④后期裂控型滑石具有相对较高的δ^(26)Mg值(-0.32‰~-0.15‰),发生滑石矿化的菱镁矿(δ^(11)B:+7.7‰~+8.4‰)和围岩变粒岩(δ^(11)B:+4.3‰)显示较低的δ^(11)B值,这反映了变质热液作用所引发的Mg和B同位素分馏现象。因此,辽东半岛海城-大石桥地区菱镁矿矿床镁质富集的根本原因可能为湖相沉积碳酸盐岩经准同生阶段的富镁卤水交代所致,非后期变质热液交代作用的结果。

目的研究外膜孔道蛋白ompC、ompF引起细胞膜通透性改变与大肠埃希菌(ECO)对抗菌药物形成耐药的相关性。方法设计复合引物对ompC全基因序列和ompF、ompA、fepA、cirA、chuA等基因序列进行扩增,回收PCR产物、钝化后测序;菌体外膜蛋白进行SDS-PAGE电泳,回收的目标膜蛋白条带经胰蛋白酶消化,采用质谱仪分析蛋白成分并进行蛋白序列的测定。结果SDS-PAGE电泳图谱和质谱分析显示,7株大肠埃希菌均有相应的外膜孔道蛋白ompC和ompA表达,无外膜孔道蛋白ompF表达;第6、7菌株的孔道蛋白ompC和ompA表达量明显减少,但有铁运输蛋白chuA、cirAf、epA的表达;基因扩增显示7株大肠埃希菌均有ompF产物,耐药性较强的第6、7菌株还有fhuA和cirA扩增产物,但产物fhuA的相对分子质量小于ECO-k12(少54 bp)。结论持续使用抗菌药物将导致细菌外膜孔蛋白ompF低表达或不表达,外膜孔蛋白ompC氨基酸序列的改变影响相应蛋白的表达,使细胞膜通透性降低,从而增加细菌对抗菌药物的耐药性;高度耐药的大肠埃希菌伴随代偿性铁运输蛋白chuA、cirA、fepA的表达,维持细菌的新陈代谢,保持其高水平耐药性。
