延伸数量关系
RelationExtendedToQuantities 是一个 Relation,如果它对一串 RealNumber 的参数值是真的,那么 他对一串有着和一些衡量单位幅度 ConstantQuantity 的实例也是真的。例如: lessThan 关系可延伸到数量 上, 意思是(lessThan ?QUANTITY1 ?QUANTITY2) 对于 ?QUANTITY1 和 ?QUANTITY2 所有的数量对, 当且仅当对于某些 ?NUMBER1,?NUMBER2 和 ?UNIT,?QUANTITY1 = (MeasureFn ?NUMBER1 ?UNIT), ?QUANTITY2 = (MeasureFn ?NUMBER2 ?UNIT)和(lessThan ?NUMBER1 ?NUMBER2),对于所有 ?QUANTITY1 和 ?QUANTITY2 可以量度的单位 ?UNIT。注:当一个 RelationExtendedToQuantitiesRealNumber 被延伸到 ConstantQuantity 的实例实时,该 ConstantQuantity 必须以相同的实物尺寸 来量度。

Parents 可继承的关系 The class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
  关系 The Class of relations. There are three kinds of Relation: Predicate, Function, and List. 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. A List, on the other hand, is a particular ordered n-tuple.
