1. Some constructs might be unidimensional while others might tap to a number of distinct facets. 有些构造可能是单维的，而另一些则可能发掘到不同层面的数目。
2. This article adopts unidimensional optimization method to optimize the design, and optimum parameter can be attained. 筒尺寸进行优化设计，确定其最佳工艺参数。
3. Conclusion multidimensional IRT is more appropriate than unidimensional IRT for the analysis and evaluation of multidimensional and short scale. 结论多维irt更适合于条目数较少的多维量表的分析和评价。
4. As numerous complex factors that influence poverty and environmental degradation existed, so poverty-environmental linkages cannot be reduced to simple unidimensional cause-effect relationships. 由于有许多复杂的因素在它们之间发挥着作用，所以，贫困与环境的联系不能被简单认定为一维的因果关系。
