摘　　要：形式逻辑教科书中关于充分条件假言命题的定义及其列举的某些例句,值得质疑。对形如"如果p,那么q"的命题,应以其前、后件本身是不是真值确定的命题为标准,划分成两类,充分条件假言命题只是其中一类。由此出发,加以辨析,求解由逻辑学教科书中"充分条件假言命题"定义而引出的有关问题。It is worth questioning that the definition of a hypothetical proposition under sufficient con- ditions and some of its examples which are enumerated in the textbooks about formal logic. Those propositions whose formal structure look like ＂if p, then q＂ should be divided into two kinds, and the basis of division is whether the ＂p＂ and ＂q＂ are propositions, so that a hypothetical proposition under sufficient conditions belong only to the one subterm of division. Starting with this, this paper analyzes and solves some related questions by the definition of ＂hypothetical proposition under sufficient condi- tions＂.
