The model has its continuity and incontinuity.

该模型具有连续性和非连续性,前者表示每一个言语行为都具有四个层次:表意行为,命题行为,以言行事行为和言效行为,并且人们可以同时实施这四种层次;后者表示以言行事行为或言效行为只有在特定的语境中才能引发受众的反应,其很大程度上取决于文化差别,语境特征(诸如语域,具体语境话题和某一语境中的信息量等),以及人们的知识结构等。

Based on substitution of the indiscernibility relation by a dominance relation and a confident threshold value a set, an extension of the rough sets model is proposed, which can deal with possible inconsistencies in preferential multiple attribute decision tables and obtain preferential probabilistic decision rules made up of preference actions.

摘要通过用优势关系代替不可分辨关系,并设定置信阈值α,提出了一种可以从偏好多属性决策表中发现偏好概率规则集的扩展粗糙集模型。

Based on the ETA/VPG and LS-DYNA software platform and "vehicle-barrier-curve-road" integrated system dynamics model, in the research, the orthogonal experimental design method and the dynamic explicit finite element method were applied jointedly. The rear wheel elevation was considered as criterion for evaluation and six cross-sectional shape design variables were created. The application of L25 (5^6) orthogonal table for simulation and the use of SPSS statistical package help the variance analysis of simulation results, and the influence levels of various factors were studied to determine the optimal parameters of concrete barrier.

Firstly, the reaction thermodynamics was analyzed. Then, the reaction mechanism was studied, and the results are as following:① Ca moves to the surface of Dy〓O〓 by vapor phase;② Dy〓O〓 reduced to Dy by Ca is fast;③ Dy moves to the Fe surface mainly by vapor and various Dy-Fe alloys are produced gradually;④ The forming process of DyFe〓 may be described by Contracting Core Model;⑤ The rate-controlling step of the reaction is the Dy diffusing toward contracted and nonreaction nuclear center Fe.
