摘　　要：在三角高程对向观测法理论的基础上,根据对向观测法的闭合差条件,提出其偶然误差特性的检验,并结合数例进行包括闭合差正负号检验、正负误差分配顺序检验、误差数值和的检验和个别误差值的检验。最后得出三角高程对向观测法闭合差具有偶然误差特性,并具有一定的正确性和现实指导意义。The paper systematically expounded on the three methods of trigonometric leveling with total--station, through deeply researched the bilateral observation, proposing the random error＇s test for the elevating angle^s closure of bilateral observation in the trigonometric leveling with some example, including the positive and negative sign＇s test about the ele- vating angle^s closure, its order test, the sum test of error and single error＇s test. Finally it＇s the conclusion that it has the property of the random error about the bilateral observation of the trigonometric leveling, and has the guiding signifi- cance to the practical work and so on.
