The sample included 96 pulsars, for which the signal-to-noise ratio ( <italic>S</italic>/<italic>N</italic>) in the main pulse of the average profile during accumulation over 10 years was more than 40. It was found that PSR J1543+0929 has radiation for almost the entire period. The profile is three-component. The relative amplitudes of the lateral weak components are 0.013 and 0.025. For PSR J2234+2114, a precursor was detected that is 53◦ away from the MP.</p></abstract><trans-abstract xml:lang="ru"><p>Проведен поиск слабых компонентов вне главного импульса (ГИ) в излучении пульсаров на частоте 110 МГц, наблюдавшихся на телескопе БСА ФИАН в Пущинском многолучевом поиске пульсаров (PUMPS). Выборка включала 96 пульсаров, для которых отношение сигнала к шуму в главном импульсе среднего профиля при накоплении за 10 лет было больше 40. Было обнаружено, что PSR J1543+0929 имеет излучение практически весь период. Профиль является трехкомпонентным. Относительные амплитуды боковых слабых компонентов составляют 0.013 и 0.025. Для PSR J2234+2114 был обнаружен предимпульс, отстоящий от ГИ на 53◦.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pulsars</kwd><kwd>average profiles</kwd><kwd>extended radiation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>пульсары</kwd><kwd>средние профили</kwd><kwd>протяженное излучение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>D.J.
