The original motivation is that we found the standard Z refinement relation is not adequate or correct when considering specifications that have temporal relationships of operations. The concept of temporal state variables is introduced into Z. Then new implementation relations are defined and new refinement relations are deduced, mainly for temporal state variables to process temporal relationships of operations. We use state transition systems to abstract the temporal state transitions. A simple example is used to show the procedures of MVORM. Finally some directions of further work are forwarded.展开更多

This paper develo...Traditional requirements method has some problems when it is used for large distributed systems. Multiple viewpoints oriented requirements method (MVORM) is a new method for resolving these problems. This paper develops two generic formal frameworks of MVORM, framework based on refinement relation (FBRR) and framework based on implementation relation (FBIR). They are generic, because no assumptions are made about the development process or the formal description languages to be used. Three kinds of specification relations and three kinds of specification transformations are discussed over FBIR and FBRR. This paper also compares the equivalence between FBIR and FBRR. We point out that an equivalent FBIR can be found for any FBRR, but reverse transformation is not always possible. We think FBIR is better than FBRR on most cases.展开更多

Based on the multiple compounding of the charactemtic town planning, it is significant to combine tiie universal viewpoint widi traditional small town planning. This paper by combining with “universaT viewpoint introduced the transformation of traditional small town planning in theory and practice, and combed the planning stategies from the 4 a^ects of “all level”,“all space”, “all element^,and “all dimension”. Based on the master plan of Guzhu Town in Heyuan, specific strategies were put forward from the 6 dimensions of resoutce analysis, spatial layout, industtiai construction, traffic connection, ecological control and system update, to provide references for the planning of characteristic towns.展开更多

In order to implement this association function, it is necessary to quantify the degree of association between two concepts. In the present paper, we propose a method for quantifying degree of association focusing on the viewpoint that uses a concept base (a knowledge base that expresses concepts as a collection of pairs, each pair consisting of an attribute word used to describe the concept and a weighting that expresses the word's importance). Here, "Viewpoint" is the perspective from which a concept is viewed; for example, consider the degree of association between "airplane" and "automobile", and the degree of association between "airplane" and "bird". From the viewpoint of "vehicle", "airplane" and "automobile" are highly related, while from the viewpoint of "flight", "airplane" and "bird" are highly related. We present herein a comparison of two methods for calculating degree of association focusing on the viewpoint, and demonstrate that the method involving modulation of attribute weightings based on viewpoint results in degree of association calculations that are closer to human senses.展开更多

Here it is necessary for us to point out that they cannot be mentioned in the same breath, because the modern ecological criticism is not the reduction of an ancient ecological thought, and also will lead to the academic non-compatibility in academic research. So only by correcting the people's misunderstanding in cognition, can we reach the unity of the natural ecological viewpoint and man civilized viewpoint so as to keep the harmony between human beings and nature.展开更多

Also the antioxidant activity of thymol was investigated in gas phase and ethanol. The effects of NMe2, OEthyl and Me substituents on the antioxidant activity and adsorption ability of thymol on AlP-nanotube were investigated. Results show that AlP-nanotube can effectively interact with substituted thymols, so their adsorptions are exothermic and experimentally possible from the energetic viewpoint. Results also show that, replacing NMe2 group in the x position of thymol may be a good strategy to improve the sensitivity of thymol toward AlP-nanotube surface. The NMe2 and OEthyl substitutions decrease the BDE and IP values and increase the antioxidant activity of thymol. The BDE and IP values of thymols have linear dependencies with corresponding Ead values. These can be utilized to select novel thymol derivatives with higher antioxidant activity and drug delivery ability.展开更多

文摘We have studied the adsorption of thymol derivatives on AlP-nanotube surface by using density functional calculations in gas phase. Also the antioxidant activity of thymol was investigated in gas phase and ethanol. The effects of NMe2, OEthyl and Me substituents on the antioxidant activity and adsorption ability of thymol on AlP-nanotube were investigated. Results show that AlP-nanotube can effectively interact with substituted thymols, so their adsorptions are exothermic and experimentally possible from the energetic viewpoint. Results also show that, replacing NMe2 group in the x position of thymol may be a good strategy to improve the sensitivity of thymol toward AlP-nanotube surface. The NMe2 and OEthyl substitutions decrease the BDE and IP values and increase the antioxidant activity of thymol. The BDE and IP values of thymols have linear dependencies with corresponding Ead values. These can be utilized to select novel thymol derivatives with higher antioxidant activity and drug delivery ability.
