The principle used is known as conservation balance principle.The general equation for the conservation of material for the pH process may be written as follows Based on this general equation, two equations have been derived to express the pH process in the CSTR system.The general approach is adopted by previous researchers in this field example like McAvoy, Hsu, & Lowenthals 1972 [7] (1) (2) V:Volume of the reactor tank ,: Flowrates of acid and alkaline streams respectively. ,: Concentration of acid and alkaline respectively α, β: Non-reactant components of acid and alkaline.

There are varieties of definitions about it, but most people would like to agree to this kind of definition that is “Enterprise culture refers to the common values, norms, moral regulations and customs which is widely accepted and observed by the members of the enterprise, and the regulation, structure as well as material entity which react to the enterprise cultural traits.

Discussion The word "direct footing" is fisrt seen in an article writen by Zhang ZaiMing [8], the academician of Chinese Academy of Engineering, which is the equivalent of using "natural foundatio" and "shallow foundafion", and which is the only one from CNKI (China national knowledge internet) full-text precise retrieval; By Google search, can only find "Footings Direct Ltd", which is a British building company, located in Essex, and web site is http://www.footingsdirect.co.uk/; By ChinaInfo search, can only find a article in Eurofruit magazine in 2007, the topic is " Luis Vicente strengthens counterseasonal import business: The buoyant exotic fruit sector has encouraged the Portuguese giant to establish a direct footing in far-flung production zones ", the word "direct footing" in the sentence can be translated as "direct based on"; Finally, through the ChinaInfo full-text precise retrieval (including journal articles, dissertation, conference papers, Chinese and foreign patents, scientific
and technological achievements, Chinese and foreign standards, laws and regulations), find four Japanese patent use the word "direct footing", which are SOIL IMPROVEMENT METHOD BY COMPACTION PILE MAKING USE OF RECYCLED GRANULAR MATERIAL, ARCHITECTURAL STRUCTURE REBUILDING METHOD AND FOOTING STRUCTURE USED THEREFOR, SLOPE FOOTING STRUCTURE, and BASE-ISOLATION ARTIFICIAL FOOTING, involving in geotechnical engineering field of foundation treatment, and pile partner seems to be able to do something about these respects.

These instructions may be able to improve the physical impact of space environmental conditions in urban settlements is not a neighborhood interaction and interpersonal determinants; thus also may be able to guess the current increase in urban settlements of traditional architecture interpersonal theory of public relations for the space environment to stimulate settlements residents are not fully explore the potential interaction; In short, by more than settlements in Kunming, several research visits, and organize a large number of photos, graphs, charts and other information can be found, excellent facilities, perfect environment for planning and design, indeed urban settlements residents provided a better interpersonal material base and the interactive status of the residents a little improvement to occur, but, according to the traditional architectural theory, public relations planning and design of settlements, space and environmental facilities fully as we would like not leaving the

Because the construction and development of new city will rely more on the expansion of urban size, this will take up a lot of land and consume large amounts of water, energy and other material resources.
