摘　　要：直陈条件句的前件、后件是可以单独断定真假的,但整个直陈条件句是否有真值,却是一个有争议的问题。如果把直陈条件句作真值函项的解释,则会出现一些违反人们直觉的怪论,为了消解这种怪论,有些学者提出了NTV观点,这种观点认为直陈条件句不是真值函项的,直陈条件句没有真值,这引发了一个重要的逻辑哲学问题,即直陈条件句有无真值的问题。For indicative conditionals,the truth-value of antecedent and consequents is individually asserted,but the truth-value of indicative conditionals is a controversial issue.If we treat indicative conditionals as truth-functional,some paradoxes will arise.In order to interpret them,some scholars proposed the view of NTV,claiming that indicative conditionals have no truth condition and no truth-value.This view provokes an important logic philosophy problem,namely,whether indicative conditionals have truth-value.

关 键 词：直陈条件句 NTV观点 真值 合理性
