根据傅里叶光学原理,研究了二维Thue-Morse准周期光子晶体结构的格点形状对其远场衍射特性的影响。通过对二维Thue-Morse准周期光子晶体远场衍射图案的分析表明,格点形状对低阶结构的衍射光场有明显影响,但不改变高阶结构的衍射光场分布,仅衍射精细结构的光强度有细微差别。为了证实数值模拟的结果,采用电子束刻蚀技术在聚甲基丙烯酸甲酯(PMMA)基底上制作了纳米量级的圆形空气孔和方形空气孔的二维Thue-Morse型准周期光子晶体,对其远场衍射的光学特性进行了实验观测,实验结果与理论模拟一致。

Aegiliops tauschii is classified into two subspecies： Ae. tauschii ssp. tauschii and Ae. tauschii ssp. strangulata. Novel genetic variations exist in Ae. tauschii ssp. tauschii that can be utilized in wheat improvement. We synthesized a hexaploid wheat genotype（SHW-L1） by crossing an Ae. tauschii ssp. tauschii accession（AS60） with a tetraploid wheat genotype（AS2255）. A population consisting of 171 F8 recombinant inbred lines was developed from SHW-L1 and Chuanmai 32 to identify QTLs associated with agronomic traits. A new genetic map with high density was constructed and used to detect the QTLs for heading date, kernel width, spike length, spikelet number, and thousand kernel weight. A total of 30 putative QTLs were identified for five investigated traits. Thirteen QTLs were located on D genomes of SHW-L1, six of them showed positive effect on agronomic traits. Chromosome region flanked by wPt-6133–wPt-8134 on 2D carried five environment-independent QTLs. Each QTL accounted for more than 10% phenotypic variance. These QTLs were highly consistent across environments and should be used in wheat breeding.

清洁能源系统比传统能源系统更具金属密集性,清洁能源技术关键伴生金属可供性将成为制约清洁能源技术发展的潜在瓶颈。本文以镓为例,重点关注与清洁能源技术相关的终端需求,综合考虑载体金属氧化铝供求-价格和伴生金属镓供求-价格的相互作用关系建立系统动力学模型。在对模型进行有效性检验后,从全球经济增长率、太阳能电池发电总需求和技术进步3个参数出发设计8种情景,对全球镓可供性演化情况进行了仿真分析。结果显示:(1)在基准情景下,预计镓的需求和供给在模拟期间始终呈上升趋势,镓需求的年均增长率为12%,镓供给的年均增长率为10.7%.镓供求比的峰值出现在2039年,达最大值0.9,镓供需缺口最小;到2050年镓的供求比将降至0.6,镓的供给严重短缺,镓的价格预计将达到1262万元/吨,约为2001年的3倍;(2)情景分析结果表明,提高全球经济增长率、降低太阳能电池发电总需求和加快技术进步能够有效缓解金属镓供给短缺。提高全球经济增长率对缓解金属镓供给短缺的作用最大,加快技术进步的作用次之,而降低太阳能电池发电总需求的作用最低。最后,本文提出了化解镓资源约束的对策。
