多级的

Then according to the cascade of IPS and LPS, the multi-stage rearrangeable nonblocking Omega network was introduced. Moreover, the method of bipartition graph was adopted to ascertain the node state of each stage. At last, a module of the rearrangeable nonblocking Omega network, which was integrated with polarizing beam-splitter,λ/2 wave plate and perfect shuffle Plates, was constructed.

该方法通过逆混洗(Inverse Perfect Shuffle， IPS)和左混洗(Lott Perfect Shuffle， LPS)的串联，构成多级的可重排、无阻塞的Omega网络，采用二分图法依次确定各级节点开关的状态，最后通过偏振分光棱镜(Polarizing Beam Splitter， PBS)、半波片(λ/2 wave plate)和PS Plate的组合，得到可重排、无阻塞的Omega网络交换模块。

So research in the cognitive diagnosis under polytomous scoring model is very meaningful.

随着布什总统&不让一个孩子落下&的政策出台，美国的认知诊断研究也逐渐成为热门，但目前的大部分研究仍基于0.1 评分，而多级评分可以提供更丰富的信息，并且我国的试题类型往往是多级评分的，因此研究基于多级评分的认知诊断具有重要的意义。1 本文采用模型介绍1.1 目前同类相关研究采用的模型及方法1.1.1 多级评分个人拟合统计量Drasgow提出的多级评分个人拟合统计量指标_l J可以将多级评分模型中被试是否属于异常反应诊断判别出来，但该指标功能局限性大，只能对被试反应模式是否正常做出定性说明，还不能指出哪些属性掌握与否，尚达不到针对考生不足之处进行补救教学的目的。1.1.2 Tatsuoka的规。。。。。。

Polychotomously scored system is better than dichotom-ously scored system,because it makes fuller use of theinformation involved in the examinees response vectorto all test items.2,The assumpt on of dichotomizing polychotomously scoredtest data and the relevant test transferring method isreasonable,the two tests are equivalent.3,Dichotomously scored IRT models are avalable to polych-otomously scored tests if these tests satisfy the assump-tions of the models.

对测验项目采用多级评分有助于更大限度地利用被试对测验项目的反应中所包含的有关其相应的能力或特质水平的信息量。2：本文所提出的把多级评分测验结果二级化的设想和方法是合理的和可行的。3：有本文所提供的方法把多级评分测验转换成相应的虚拟二级评分测验并不会改变原测验的各种性质。这两个测验基本上是等价的。4：只要原多级评分测验满足IRT模型的各种假设，那么该测验所对应的虚拟测验与逻辑斯蒂模型是配匹的。5：把二级评分IRT模型用于多级评分测验是可行的。
