摘　　要：目前一些文章中对正确恢复三基色需要满足什么条件,以及电路参数的变化对基色恢复的影响等问题分析较少。本文用等效电路法对典型的基色矩阵电路作了一定的理论分析,从此出发讨论了正确恢复出三基色对基色矩阵电路的要求。最后对影响三基色正确恢复的因素也作了一定的分析。结合上述分析得到了最终结论。At present, there are not many papers analysing the conditions to restore correctly for three primary colors and the influence which restores to the primary color with the circuit value＇s changes. This paper firstly analyses typical color matrix circuit by equivalent circuit method, then based on this discusses the requirement of color matrix circuit for how to restore correctly for three primary colors. Finally, the factors that three primary colors restores correctly are analyzed. Through the above analysis a final conclusion has been given.
