This attempt constitutes an innovative approach, since it is based on externalizing domain knowledge in the form of Ontology-Based Knowledge Networks, incorporating standardized methodology in soil engineering. The ontology soil/water concepts (semantics) of the developed network correspond to soil/water physicochemical & biological properties, classified in seven different generations that are distinguished/located in infiltration/percolation process of contaminated water through soil porous media. The interconnections with arcs between corresponding concepts/properties among the consecutive generations are defined by the relationship of dependent and independent variables. All these interconnections are documented according to the below three ways: 1) dependent and independent variables interconnected by using the logical operator “<em>depends on</em>” quoting existent explicit functions and equations;2) dependent and independent variables interconnected by using the logical operator “<em>depends on</em>” quoting produced implicit functions, according to Rayleigh’s method of indices;3) dependent and independent variables interconnected by using the logical operator “<em>related to</em>” based on a logical dependence among the examined nodes-concepts-variables. The aforementioned approach provides significant advantages to semantic web developers and web users by means of prompt knowledge navigation, tracking, retrieval and usage.展开更多

Both national and local governments have been paying great attention to the work of industrial standardization with the enormous increase in international trade after China joined WTO. According to the standards revising plan of Standardization Administration Committee of China (SAC),TC54 has already revised a series of national standards and industrial standards for foundry operations,and proposed some new ones. As a result,some old fashioned standards containing low-level techniques have been gradually discontinued or replaced with new versions.……展开更多

The Hygienic Standard of Fermented Bean Products
This standard stipulates the specification, food additives, hygienic requirements of production and processing, packaging, marking, storage and transportation requirements and inspection methods for fermented bean products. It applies to fermented bean products such as fermented bean curd, fermented soya beans and fermented beans made from soya beans and other beans.展开更多
文摘This standard specifies the terms and definitions, theory, apparatus, specimens, test procedures, calcu- lation results, apparatus check and test reports, etc. of abrasion resistance at ambient temperature of refractory products.
文摘The similarities and differences of ASTM and China GB standard are studied in three aspects:measure instrument,terminology and applicable field.They are similar on the measuring apparatus and GB has less measurements,such as girth,length and width measurements than ASTM and it lack across chest width,back width,total crotch length and shoulder slope which are important measurements in pattern making.ASTM classifies its standards according to the customers' size,gender and age.So we think GB standard could make some modifications from these fields to satisfy the users.
