This analytical model gives detailed geometrical parameters of the machine, where the maximum geometry, the working point of the magnet and the maximum flux density in the ferromagnetic materials were pre defined.
The main difference between the build-up of the two machines is the material of the piston rod.
ARMCO material were used, which has approximately 2 T saturation point.

Materials flow indices of aluminum industry in China in 2003-2006 were also analyzed (Fig.4).
As the aluminum scrap which we use today, Fig.4 Materials flow indices for aluminum industry in China in 2003-2007 0 10 20 30 40 50 60 70 80 90 100 Z1 J1 Z2 J2 Z3 J3 ZS JS AS 2003 2004 2005 2006 2007were originated from the aluminum products produced over 15 years ago, and the output of aluminum products in China in the 1990s were only 1/11-1/9 of her contemporary aluminum products, even though all the aluminum products may be changed into aluminum scrap, they should merely provide a small amounts of the materials required.

Research Status The network information explosion, the acquisition of agricultural information is still difficult, especially for those in need of agricultural science and technology information and market information of enterprise, department, farmers, they through the comprehensive search engine and cannot find what they need information quickly.
This paper uses the results of existing search web sites as resources information database, it returns the results is no longer does not have an associated Web page classification sets, but divided into agricultural science research units, agricultural specialist, agriculture practical technology, product supply and demand, product vendor sets of related information on the web page, whose recall level is improved; The similarity calculation based on HowNet through a series of sememe, using knowledge description language to describe a concept, and then calculate the similarity to the two language expression, so precision also improved.

A computational grid was coined in the mid-1990s to denote a (then) proposed distributed computing infrastructure for advanced science and engineering [4].
Grid management system means to complete the grid division and code for management region in accordance with certain standard system, then daily management is implemented by working personnel; basic data system is designed to achieve mutual correlation among information relating to the people, geology, material and organization, for instance, to correlate demographic data with householder register data, householder register data with house data, house data with the grid, and the grid data with geographical map, thus forming the data system featuring four-in-one (resident, house, grid region and map); the basic geosystem is designed to collect, store, manage, compute, analyze, display and describe geological distribution data relating to the whole or part epigeosphere (including the atmosphere), meeting the requirement of both the government and public for the basic geological information.
