The curve for satisfaction degree of commodity exchange has been drawn out with S (surplus volume of exchange) and M( the satisfaction degree of exchange).
文中利用交换剩余S量化交换满意程度M，得到商品交换满意程度曲线。
The results show that for the three lever mechanism concerned in the paper the variation curve of m with s is approximately linear, and only when s is near to a limit Sc, does m steeply rise with s.
结果表明，对于本文所考虑的三杠杆扩力机构，扩力系数M随S的变化曲线近似线性，仅在接近s的允许极限值时，M随S急剧上升。
