目录1、比例<Object: word/embeddings/oleObject1.bin>
具有以下性质：
（1）<Object: word/embeddings/oleObject2.bin>
（2）<Object: word/embeddings/oleObject3.bin>
（3）<Object: word/embeddings/oleObject4.bin>
（4）<Object: word/embeddings/oleObject5.bin>
（5）<Object: word/embeddings/oleObject6.bin>
（合分比定理）
2、增长率问题
设原值为
<Object: word/embeddings/oleObject7.bin>
，变化率为
<Object: word/embeddings/oleObject8.bin>
，若上升<Object: word/embeddings/oleObject9.bin>
<Object: word/embeddings/oleObject10.bin>
若下降升
<Object: word/embeddings ...
