硅基MIS隧道发光二极管为制造用于超大规模集成电路的硅基发光器件提供了可能性。报道了MIS隧道发光二极管(MISLETD)的制作过程、电流－电压和发射光谱特性，讨论了负阻现象和发光机理。

金属/绝缘层/硅（MIS）隧道二极管的发光机理

金属/绝缘层/硅(MIS)隧道发光二极管的发光机理可以归结为表面等离极化激元(SPP)与界面粗糙度的耦合。电流－电压特性曲线中6.5V附近的一个负阻和发射光谱中475nm的峰显示，在硅/二氧化硅界面激发起了与之相应的等离子体振荡。

The complete mitochondrial genome of the ridgetail white prawn Exopalaemon carinicauda Holthuis, 1950 (Crustacean: Decapoda: Palaemonidae) revealed a novel rearrangement of tRNA genes

The complete mitochondrial (mt) DNA sequence was determined for a ridgetail white prawn, Exopalaemon carinicauda Holthuis, 1950 (Crustacea: Decopoda: Palaemonidae). The mt genome is 15,730 bp in length, encoding a standard set of 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA genes, which is typical for metazoans. The majority-strand consists of 33.6% A, 23.0% C, 13.4% G, and 30.0% T bases (AT skew = 0.057: GC skew = -0.264). A total of 1045 bp of non-coding nucleotides were observed in 16 intergenic regions,,including a major A+ T rich (79.7%) noncoding region (886 bp). A novel translocation of tRNA(Pro) and tRNA(Thr) was found when comparing this genome with the pancrustacean ground pattern indicating that gene order is not conserved among caridean mitochondria. Furthermore, the rate of Ka/Ks in 13 protein-coding genes between three caridean species is Much less than 1, which indicates a strong Purifying selection within this group. To investigate the phylogenetic relationship within Malacostraca, phylogenetic trees based oil Currently available malacostracan complete mitochondrial sequences were built with the maximum likelihood and Bayesian models. All analyses based oil nucleotide and amino acid data strongly support the monophyly of Decapoda. The Penaeidae, Reptantia, Caridea, and Meiura clades were also recovered as monophyletic groups with Strong Statistical Support. However, the phylogenetic relationships within Pleocyemata are unstable, as represented by the inclusion or exclusion of Caridea. (C) 2009 Elsevier B.V. All rights reserved.

烟厂MIS中成本核算子系统实现时的几个重要问题

针对工厂企业中用微机实现管理信息系统(MIS)时,数据量大与数据处理速度慢、存储空间小之间的矛盾,本文论述了在不更新设备和不增加投资的条件下如何用软件方法来解决问题.在延吉卷烟厂成本核算子系统中的实践结果是:数据处理速度可提高到原来的2.24倍,所节省的存储空间相当于目前实际占用数的56%.
