摘要翻译：
证明了数域的余维2上的Bloch积分立方高阶Chow复形中分数次线性圈之间的关系，这些关系对应于对数函数方程。正如我们将用几个例子证明的那样，这些关系足以在Bloch积分高周群CH^2(F，3)中写下足够多的关系，用于检测一定数目的场F的扭转循环。利用调节器映射对上同调进行去木素化，可以检验由此得到的扭转圈的非平凡性。利用这两种方法的组合，我们得到了生成某些数域的积分动上同调群的显式高周圈。

英文摘要：
We prove relations between fractional linear cycles in Bloch's integral cubical higher Chow complex in codimension two of number fields, which correspond to functional equations of the dilogarithm. These relations suffice, as we shall demonstrate with a few examples, to write down enough relations in Bloch's integral higher Chow group CH^2(F,3) for certain number fields F to detect torsion cycles. Using the regulator map to Deligne cohomology, one can check the non-triviality of the torsion cycles thus obtained. Using this combination of methods, we obtain explicit higher Chow cycles generating the integral motivic cohomology groups of some number fields.
