    • A lattice-matched solar cell having a dilute nitride-based sub-cell has exponential doping to thereby control current-carrying capacity of the solar cell. Specifically a solar cell with at least one dilute nitride sub-cell that has a variably doped base or emitter is disclosed. In one embodiment, a lattice matched multi junction solar cell has an upper sub-cell, a middle sub-cell and a lower dilute nitride sub-cell, the lower dilute nitride sub-cell having doping in the base and/or the emitter that is at least partially exponentially doped so as to improve its solar cell performance characteristics. In construction, the dilute nitride sub-cell may have the lowest bandgap and be lattice matched to a substrate, the middle cell typically has a higher bandgap than the dilute nitride sub-cell while it is lattice matched to the dilute nitride sub-cell. The upper sub-cell typically has the highest bandgap and is lattice matched to the adjacent sub-cell. In further embodiments, a multi junction solar cell according to the invention may comprise four, five or more sub-cells in which the one or more sub-cells may each comprise exponentially doped dilute nitride alloys.
    • 具有稀氮化物基子电池的晶格匹配太阳能电池具有指数掺杂,从而控制太阳能电池的载流能力。 具体地说,公开了具有至少一个具有可变掺杂的基极或发射极的稀氮氮化物子电池的太阳能电池。 在一个实施例中,晶格匹配多结太阳能电池具有上部子电池,中间子电池和下部稀的氮化物子电池,下部稀土氮化物子电池在基极和/或发射极中具有掺杂, 至少部分地指数地掺杂,以便改善其太阳能电池性能特征。 在构造中,稀氮氮化物子电池可能具有最低的带隙并且与衬底晶格匹配,中间电池通常在稀氮化物子电池与氮化稀土子电池晶格匹配时具有较高的带隙。 上部子单元通常具有最高的带隙并且与相邻的子单元格子匹配。 在另外的实施例中,根据本发明的多结太阳能电池可以包括四个,五个或更多个子电池,其中一个或多个子电池可以各自包含指数掺杂的稀氮化物合金。

    • A method and computer-readable medium are provided that construct a collocation mistake pattern database for use in writing in a first language by a person whose native language is a second language. The method includes obtaining a bilingual corpus having sentences in first and second languages and extracting second language word pairs from the second language sentences in the corpus. For each second language word pair extracted from the corpus, a corresponding first language word pair is extracted from the corresponding first language sentence in the corpus to determine a correct first language translation for the second language word pair. Also, for each second language word pair extracted from the corpus, a set of combinations of first language translation words corresponding to the second language word pair is created. Finally, for each second language word pair extracted from the corpus, the correct first language translation is removed from the set of combinations of first language translation words such that the set of combinations represent a set of collocation mistake first language word pairs corresponding to the second language word pair.
    • 提供了一种方法和计算机可读介质,其构造由本地语言是第二语言的人以第一语言书写的搭配错误模式数据库。 该方法包括获得具有第一语言和第二语言的句子的双语语料库,并从语料库中的第二语言句子中提取第二语言词对。 对于从语料库中提取的每个第二语言对,从语料库中的对应的第一语言句子中提取相应的第一语言对,以确定第二语言单词对的正确的第一语言翻译。 此外,对于从语料库提取的每个第二语言对,创建与第二语言对对应的第一语言翻译单词的组合。 最后,对于从语料库中提取的每个第二语言词对,从第一语言翻译词的组合的集合中去除正确的第一语言翻译,使得该组合组合表示与第二语言翻译对对应的一组搭配错误的第一语言单词对 语言对。
