A market is often stratified and unidimensional, and many such stratified unidimensional markets put together make a multi dimensional market.(市場存在分層的平面市場現(xiàn)象，分層平面市場疊加形成立體市場。)

This article adopts unidimensional optimization method to optimize the design, and optimum parameter can be attained.(筒尺寸進(jìn)行優(yōu)化設(shè)計(jì)，確定其最佳工藝參數(shù)。)

Some constructs might be unidimensional while others might tap to a number of distinct facets.(有些構(gòu)造可能是單維的，而另一些則可能發(fā)掘到不同層面的數(shù)目。)

As numerous complex factors that influence poverty and environmental degradation existed, so poverty-environmental linkages cannot be reduced to simple unidimensional cause-effect relationships.(由于有許多復(fù)雜的因素在它們之間發(fā)揮著作用，所以，貧困與環(huán)境的聯(lián)系不能被簡單認(rèn)定為一維的因果關(guān)系。)

Conclusion multidimensional IRT is more appropriate than unidimensional IRT for the analysis and evaluation of multidimensional and short scale.(結(jié)論多維irt更適合于條目數(shù)較少的多維量表的分析和評價(jià)。)
