On the Expressive Power of F-Logic Language

F-logic language is a logic database language based on frame logic.It is powerful in expressing object-oriented features.However,there was little work discussing its capability of manipulating complex objects.In this paper,the authors compare the capability of F-logic with that of logic database languages represented by COL.Through two pairs of semantic-preserving transformations,F-logic progams and their corresponding Herbrand interpretations,and vice versa.Also,the effects of negation are discussed.The results of this paper indicate that,without consideration of the effects of OID generating,F-logic language has the same power in manipulatin complex objects as COL,LDL1,and ELPS.

STUDY OF AIRFLOW HOMOGENEITY STANDARD IN REGENERATIVE CHAMBER OF TANK FURNACE

The authers compared six used criterions ofinflucencing homogeneity of moving airflow in virtue of er-rors such as variance Q,average square deviation T,homoge-neous indices H,inhomogeneous degree W,range R and non-uniform index S.The auther think that the effects of the er-rors will be magnified when all these old stnadards were cal-culated,especially for higher airflow homogeneity,thus,thereliability of these norms would be reduced.The authers putforward two new standards to lower influence of error.
