查询词典 periodical

Its theory is: evaluate periodical by various methods, and then make the results standardization, select the extreme value of these results as the final score of periodical. The research indicates that it is must been used carefully to calculate weight by combined assessing method; assessing methods based on order can't been used to combine; combined assessing based on extreme value method is propitious to establish harmonious relationship between assessor and assessee.

其原理是，首先选用各种可行的评价方法进行评价，然后将评价结果标准化，将同一期刊不同评价结果的极大值作为该期刊的最终评价结果，取得了较好的效果，研究表明，采用组合评价进行权重计算必须慎重使用；基于秩序的评价方法不能用于组合；基于极值法的组合评价方法有利于建立和谐的评价者与被评价者关系，结果容易得到公认。

There are mainly three reasons for doing so: first, the readers of financial periodicals are much easier to be distinguished from other bourgeois readers; next, the operational ways of financial periodicals portray vividly in which field medium are investing in recently, this phenomena could be counterevidence to prove the powerful influence of bourgeois periodical on the society as a whole; finally, common problems in all the bourgeois periodicals are easier to be discerned in financial ones. The choke point that might well happened in the process of orientating a certain periodical is the object of being orientated, that is, the recipients, who are human beings equipped with infinite-possible mind and infinite-potential body, as well as self-initiative consciousness and self-determining behaviour.

The bifurcation and chaos behavior of impact and rubbing fault rotor system caused by the parameters of nonlinear rigidity, rotor rotating speed, eccentric mass is analyzed, in the numerical value analysis method. The bifurcation diagrams, maximum Lyapunov exponent diagrams, Poincaré maps, phase plane portraits, trajectories of journal center, time-history curve, amplitude spectra diagrams of the rotor motion are used. The convert and evolution course of periodical response, quasi-periodical response, double-periodical bifurcation, chaos of the system response is analyzed.(3). It is deduced that the general differential equation of bending-torsional-pendular coupling vibration about rotor with the gyroscopic moment. On the basis of this equation, the general differential equations of coupled bending, torsional and pendular nonlinear vibration about rotor with unbalance character and rubbing character are deduced.
