Some special features of the method are developed for this purpose. The total variance method is demonstrated to include the errors in both dependent and independent variables. Two polynomial expansions are presented for approximating function: orthonormal and "usual" ones.</abstract><trans-abstract xml:lang="ru">В данной работе наш метод построения ортонормированных полиномов - метод расширения ортонормированных полиномов [OPEM] - применяется к изменениям краевого угла смачивания. Для этой цели развиты некоторые особенности данного метода. Демонстрируется метод полной дисперсии, чтобы включить ошибки как в зависимые, так и в независимые переменные. Два расширения полинома представлены для аппроксимирующей функции: ортонормированное и «обычное».</trans-abstract><kwd-group xml:lang="en"><kwd>orthonormal and usual polynomial approximation</kwd><kwd>drop water evaporation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>аппроксимация ортонормированными и обычными полиномами</kwd><kwd>испарение капли воды</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bonn D., Ross D.
