变量独立时误差传播定律的研究

Study on Independence Variable's Error Spread Law

当变量相互独立时,函数的中误差并不满足常规的误差传播定律。为此,推导了新的公式,并用算例证实新公式的必要性和可行性。

When variables were independent,their function errors did not meet the routine error spread law.So,new formula was deduced,and the need and feasibility of new formula was testified by examples.
