三减一等于四或者大于四,肯定不是一道算对了的算术题。但在精神产品的生产中,在电视节目投入产出的实践中,在数量与质量的取舍调控中,特别是在频道栏目数量与频道效益的关系处理中是可以达成三减一等于四或者大于四的。 Three minus one equal to four or greater than four, certainly not a right arithmetic problem. However, in the production of spiritual products, in the practice of inputting and outputting television programs, in the selection and regulation of quantity and quality, in particular, the relationship between the number of channel sections and the channel benefits can be achieved by three minus one equal to four or greater than Four’s.
