部分值关系
一个
Relation
是
PartialValuedRelation
是为了确保它不是一个
TotalValuedRelation
,也就是说除了最后一个之外给每一个 参数位置分配一个值,但这不一定等于已经为最后一个参数位置设定赋值。注:如果一个
Relation
既是
PartialValuedRelation
又是
SingleValuedRelation
的话,那么它就是一个部分函数。

The
Class
of relations. There are two kinds of
Relation
:
Predicate
and
Function
.
Predicate
s and
Function
s both denote sets of ordered n-tuples. The difference between these two
Class
es is that
Predicate
s cover formula-forming operators, while
Function
s cover term-forming operators.
