dampingRatio
(dampingRation ?SYSTEM ?NUM) is a measure of to what degree a system is free to oscillate or not. In an overdamped system ?NUM is greater than 1. The system returns (exponentially decays) to equilibrium without oscillating. Larger values of the damping ratio signify a return to equilibrium more slowly. In a critically damped ?NUM equals 1. The system returns to equilibrium as quickly as possible without oscillating. This is often desired for the damping of systems such as doors. In an underdamped system 0 < ?NUM < 1. The system oscillates (at reduced frequency compared to the undamped case) with the amplitude gradually decreasing to zero. Finally, in an undamped system ?NUM is 0. The system oscillates at its natural resonantFrequency. [adapted from Wikipedia].
Relationships      
InstancesAbstractProperties or qualities as distinguished from any particular embodiment of the properties/qualities in a physical medium. Instances of Abstract can be said to exist in the same sense as mathematical objects such as sets and relations, but they cannot exist at a particular place and time without some physical encoding or embodiment.
 BinaryPredicateA Predicate relating two items - its valence is two.
 BinaryRelationBinaryRelations are relations that are true only of pairs of things. BinaryRelations are represented as slots in frame systems.
 EntityThe universal class of individuals. This is the root node of the ontology.
 可繼承的關係The class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
 PredicateA Predicate is a sentence-forming Relation. Each tuple in the Relation is a finite, ordered sequence of objects. The fact that a particular tuple is an element of a Predicate is denoted by '(*predicate* arg_1 arg_2 .. arg_n)', where the arg_i are the objects so related. In the case of BinaryPredicates, the fact can be read as `arg_1 is *predicate* arg_2' or `a *predicate* of arg_1 is arg_2'.
 RelationThe Class of relations. There are two kinds of Relation: Predicate and Function. Predicates and Functions both denote sets of ordered n-tuples. The difference between these two Classes is that Predicates cover formula-forming operators, while Functions cover term-forming operators.
