Accurate calculations are needed to check if the design goal（εh＋εv =20 pm） can be reached. In this paper, we present the results of numerical simulation studies of the IBS effect on a BAPS temporary design lattice.展开更多

Our results illustrate that the entering and escaping processes of biopolymer depend on its negative entropy, and entering process is more difficult than escaping process for biopolymer translocation. This tremendous difference between the two processes will offer a useful engineering hint for single macromolecule identification.展开更多

The great shock to uncompleted reform and excessive protection firstly means challenges and opportunities. The way to deal with this situation is to regard entering WTO as the second reform and open. By upholding opening - door policy, we can stride forward towards internationalization and really merge into world market. By expending the reform, we can actively push forward marketization, and further improve system of enterprise, market construction and governmetnt’s function. All industries should take different strategies and pay much attention to improving core technology and international competitiveness.展开更多

On the basis of analyzing problems of the current construction land market and also the causes, modern land property theory and institutional change of neoinstitutional economics are applied to study dynamical mechanism and development path of the construction land market, to construct the unifi ed construction land market system of China, and to propose corresponding guarantee policies, so as to achieve the effective allocation of construction land and maximization of social welfare.展开更多
