Study on Independence Variable's Error Spread Law

DENG Yong-he(Architecture Department,Lishui College,Lishui,Zhejiang 323000)  
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.
