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.

论文选取目标人群为中产阶层的财经期刊作为研究对象的原因有三：一是财经期刊的消费主体较其他类型的期刊来说更集中于本论文所界定的中产阶层；二是财经期刊的运营很能说明近期的媒体投资热现象，而这一现象可以证明中产期刊的总体社会影响力不可小觑；三是财经期刊品牌建设是期刊产业化链条思路的有力代表。

Also its status and significance in the literature structure in 1930s are explored from the angle of its imbroglio relationship with the literature trend of thought of that time, with the relationship between the periodical and the literature trend of thought as well as the function and significance of the periodical in the literature trend of thought as focus of attention.

历时两年时间，对我国公开出版的农业期刊进行了评选，于创】万年推出了中国农业核心期刊2田万版。中国农业核心期刊的推出，无疑给农业类期刊提供了一个更多的参考标准与依据。笔者无意对其评选的公正性等方面作深人探讨，而只是对入选期刊进行一个粗略的分析，以窥核心期刊之概况，并以此供期刊界同仁参考。

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.

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
