    • A method is provided for identifying phrase alignment pairs between a source sentence and a target sentence. Boundaries for a phrase in the source sentence are identified by requiring that a source word be aligned with at least one target word in a target sentence in order to form a boundary for the source phrase. Boundaries for a phrase in the target sentence are identified based on alignments between words in the source phrase and words in the target sentence. The words in the target phrase are examined to determine if any of the words are aligned with source words outside of the source phrase. If they are not aligned with source words outside of the source phrase, the source phrase and target phrase are determined to form an alignment pair and are stored as a phrase alignment pair.
    • 提供了一种用于识别源句和目标句之间的短语对齐对的方法。 通过要求源词与目标句中的至少一个目标词对齐以形成源短语的边界来识别源句中的短语的边界。 基于目标句子中短语的边界是基于源短语中的单词和目标句子中的单词之间的对齐来确定的。 检查目标短语中的单词以确定是否有任何单词与源短语之外的源字符对齐。 如果它们不与源短语之外的源字符对齐,则确定源短语和目标短语以形成对齐对,并将其存储为短语对齐对。

    • Reactive barriers containing magnetite and methods for making magnetite reactive barriers in situ in soil for sequestering soil contaminants including actinides and heavy metals, organic materials, iodine and technetium are disclosed. According to one embodiment, a two-step reagent introduction into soil takes place. In the first step, free oxygen is removed from the soil by separately injecting into the soil aqueous solutions of iron (II) salt, for example FeCl2, and base, for example NaOH or NH3 in about a 1:1 volume ratio. Then, in the second step, similar reagents are injected a second time (however, according to about a 1:2 volume ratio, iron to salt) to form magnetite. The magnetite formation is facilitated, in part, due to slow intrusion of oxygen into the soil from the surface. The invention techniques are suited to injection of reagents into soil in proximity to a contamination plume or source allowing in situ formation of the reactive barrier at the location of waste or hazardous material. Mixing of reagents to form. precipitate is mediated and enhanced through movement of reagents in soil as a result of phenomena including capillary action, movement of groundwater, soil washing and reagent injection pressure.
    • 公开了含有磁铁矿的反应性势垒和在土壤中原位形成磁铁矿反应性屏障的方法,用于螯合土壤污染物,包括锕系元素和重金属,有机材料,碘和锝。 根据一个实施方案,将两步骤试剂引入土壤中。 在第一步中,通过以大约1:1体积比分别将铁(II)盐(例如FeCl 2)和碱(例如NaOH或NH 3)分别注入土壤中,从土壤中除去游离氧。 然后,在第二步中,第二次注入类似的试剂(然而,按体积比为1:2,铁与盐的盐),形成磁铁矿。 磁铁矿形成有利于部分原因是由于从表面缓慢地渗入土壤中。 本发明技术适合于将试剂注入到污染羽流或源附近的土壤中,从而允许在废物或有害物质的位置原位形成反应性屏障。 混合试剂形成。 由于包括毛细管作用,地下水运动,土壤清洗和试剂注入压力在内的现象,土壤中试剂的运动介导和增强了沉淀物。
