查询词典 three-color process

Based on the equilibrium equation of an arch element the cubic nonlinear dynamic model with second order is established and the nonlinear differential dynamic system without constant term is obtained through a transfer process of T=U+b. Hence three fixed points and the homoclinic orbits are found. The critical condition of the chaotic vibration of the elastic arch is given by using the method of Melnikov function. The numerical results of the stationary and chaotic motion are given and discussed.

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。
