When the boundar y lay er theor y is used to study the film condensation o n the ver tical pla te, the erro r wa s found much bigg er in the case of m iddle or small fig ures o f Re or o n the fr o nt of the condensat ion field. To so lv e the pro blem, the theor y of ex pa nded equation was put fo rw ard to solve the pr oblem o f t he film condensation on the ver tical plate, with t he co rr espo nding contr ol equatio n and heat tr ansfer standar d obtained. T he compar iso n betw een the exper imental v alue and t he pra ctical equat ion w as made. By compar ison and analysis, t he r elat ionship bet ween the expanded equation and the heat bo undar y equation has been determined.
