      <abstract xml:lang="ru">
        <p>Обычно применяемый в электроразведке постоянным током прибли­женный способ учета влияния земной поверхности состоит в удвоении значений электрического потенциала, найденного для случая тела, на­ходящегося в электрическом поле в неограниченной вмещающей среде, т.е. при отсутствии границы раздела земля — воздух. В настоящей работе приводится анализ погрешностей, вносимых указанным выше методом учета влияния плоской земной поверхности, для тел правильной геометрической формы. С этой целью для приближенных кривых потенциала, рассчитанных с использованием обычного приема удвоения, подбирается такая форма поверхности тела, для ко­торой решение, полученное путем удвоения, оказывается абсолютно точным.</p>

        <p>Usually used in direct current electrical prospecting, the approximate method of taking into account the influence of the earth's surface consists in doubling the values of the electric potential found for the case of a body in an electric field in an unrestricted host medium, i.e., in the absence of an earth-air interface.In the present paper we analyze the errors introduced by the above method of taking into account the influence of the flat earth surface for bodies of regular geometric shape. For this purpose, for the approximate potential curves calculated using the usual doubling technique, such a shape of the body surface is selected for which the solution obtained by doubling is absolutely accurate.</p>
