新GRE考试：阅读难句解读50
Calculations of the density of alloys based on Bernal-type models of the alloys metal component agreed fairly well with the experimentally determined values from measurements on alloys consisting of a noble metal together with a metalloid，such as alloys of palladium and silicon，or alloys consisting of iron，phosphorus，and carbon，although small discrepancies remained.以伯纳尔所建立的旨在研究合金中金属成分的那类模型为基础，研究人员对合金密度进行了计算，这些计算相当程度上与某些合金测量中通过实验确定的数据趋于一致，尽管一些细小的差异依然存在。实验中测量的那类合金由一贵金属和一准金属构成，例如，钯和硅的合金，或由铁、磷、和碳组成的合金。
难句类型：复杂修饰、插入语 中华考试网
解释：前面的分句中同时有两个成分修饰主语Calculations。宾语the experimentally determined value之后的、从from开始一直到although之前的内容修饰宾语，说明宾语中determine的具体方法。
值得注意的是后面的分句中的although。在由两个分句组成的句子中，although如果出现在后面的分句的句首，则其不是表示让步，而是一种委婉地表示转折的语气，相当于but.
