Emphasis is laid on the analysis of the rational conditions for the determination of a rational lexicographic order in the order construction based on the anagrammatic reflexive signed order.

The αk-Major rule is proved to satisfy some rational conditions as anonymity,neutrality,local nondictatorship and pareto rule.

In this paper, six cardinal number rational conditions are presented, correspond to ordinal number condition given by K.

In this thesis, under the assumption that every involved choice set is normal, we systematically investigate the connections between some rationality conditions of fuzzy choice functions.

In the research on choice functions, the investigation of rationality conditions is of extremely important significance no matter whether the involved choice function is crisp or not.

Georgescu fuzzifies the theory of crisp choice function by the use of fuzzy logic connectives and establishes the rationality conditions WAFRP,SAFRP,WFCA.

For CO2 reforming of CH4 reaction,the effect of the plasma treatment conditions on the catalytic performance of nickel-based catalysts was investigated.

On the basis of the soybean dregs dietary fiber sorption with heavy metal ions under the physiological conditions,was further studied the impact of the instantaneous high pressure(IHP)on the process.

Based on the main researches on CRT, introduced the meanings of the conditional reasoning,.

The influence of three different kinds of valence(persuasive condition,dissuasive condition and neutral condition) and implicit arguments on conditional reasoning in two different positions(self and author) was researched with college students as the subjets.

Event-related brain potentials were measured when 13 normal young participants finished four kinds of conditional reasoning(MP,AC,DA,MT)tasks and one kind of baseline task(BS).
