每个女人出生的孩子
This entry gives a figure for the average number of children that would be born per woman if all women lived to the end of their childbearing years and bore children according to a given fertility rate at each age. The total fertility rate is a more direct measure of the level of fertility than the crude birth rate, since it refers to births per woman. This indicator shows the potential for population growth in the country. High rates will also place some limits on the labor force participation rates for women. Large numbers of children born to women indicate large family sizes that might limit the ability of the families to feed and educate their children.

Instances抽象体这些特质或质量,和任何以物理媒介化身的特质/质量不同。抽象 的实例在意义上,可以说是像数学物体如集合和关系般存在,但是它们不能没有任何物理编码或化身便存在于特定的时间 和地点。
 二元函数这是个需要两个参数的 Function Class
 实体The universal class of individuals. This is the root node of the ontology.
 函数Function 是一个造词的 Relation,它以最多一个元素 范围,把n元组的参数和这n元组有关的范围联系起来。注:范围是一个SetOrClass,而且范围内的每个元素是这个 SetOrClass 的一个实例。
 可继承的关系这是一个 Relation 类别,它的特性可以是 通过 subrelation Predicate 把特性在类别的层次结构承传下去。
 关系这是关系的 Class。现有三类的 Relation: PredicateFunctionListPredicateFunction 皆表示有序的n元组集合, 这两个 Class 的差别在于 Predicate 包括组成公式的运算符,而Function 则包括组成 术语的运算符,而一个 List 却是一个特定的有序n元组。
 单值关系一个 RelationSingleValuedRelation 以确保除了最后一个参数之外,每一个参数的位置只有一个赋值,而最后的参数 顶多可以决定最后一个参数的位置。注:不是所有的 SingleValuedRelation 都是 TotalValuedRelation
 三元关系TernaryRelation 连接三个项目, TernaryRelation 的两个 subclassTernaryPredicateBinaryFunction
