关于二次型非线性盈亏平衡的分析

盈亏平衡分析目的是为了降低来自市场的不确定性因素给投资人带来的风险，而非线性盈亏平衡分析更接近市场经济条件下投资项目收入与成本的实际情况，通过对其中最为常见的二次型非线性盈亏平衡分析中所涉及的收入曲线和成本曲线的各种组合的分析，为一个一般性结论提供了依据，而该结论能在二次型非线性盈亏平衡分析中寻找盈亏平衡点提供方便。

Analysis the Square Nonlinear Blance

In order to reduce the dangers for the investors arousing from indefinite factors in market, the balance of profit and loss is analysed. But the analysis of nonlinear balance is more close to the real state of the investment programme income and cost in the market economy. It is analysed that the various combination of income and cost curves in the square nonlinear balance, the proof for a common conclusion is obtained. This conclusion can make it convenient to gain balance point in the analysis of the square nonlinear balance.
