查询词典 relational

Halford et al. proposed a theory of relational complexity to interpret the essence of task difficulty. To be exact, the difficulty of task can be determined by the number of argument or dimension related, which is called the re?鄄lational complexity. The relational complexity is increased with the processing demand. We can adopt such mech?鄄anisms as conceptual chunking and segmentation to reduce the complexity.

哈尔福德等人提出了评估任务难度的关系复杂性理论，认为任务难度可由相关的变量数量即关系复杂性来确定；关系复杂性越大加工要求也越高，这时可采取概念组块和分解机制来减少复杂性；认知发展阶段可归因于随着年龄的增长能够加工的关系复杂性的增加。

It was showed through field trials and pot trials that the content of Zn, Cu and Mn in cole was relational to the total content and bio-available content of that in soils respectively, and the content of As was relational to the total content and bio-available content of As in soils indistinctively, and the content of Cd, Ni, Pb and Cr in cole was under the measure limit.
