In the process of precasting the voided slab made of the pre\|tensioned prestressed concrete(PC) if the degree of the opposite deflection is nonuniform, it shall effect the whole quality of the slab. This article, combined with the experience of works construction, analyzes the factors influencing the degree, and gives some specific ways to control the degree of the opposite deflection.\;
