      <abstract xml:lang="ru">
        <p>В силу особой чувствительности алмазов к действию температур­ного фактора соблюдение нормального теплового режима алмазных коронок в процессе бурения является одним из основных условий их эффективной работы. Нормальным следует считать такой тепловой режим, при котором температура нагрева алмазов не достигает вели­чины, вызывающей их окисление, графитизацию или деформации вследствие температурных напряжений.</p>

      <abstract xml:lang="en">
        <p>Due to the special sensitivity of diamonds to the temperature factor, compliance with the normal thermal regime of diamond bits during drilling is one of the main conditions for their efficient operation. The normal thermal regime should be considered to be such a thermal regime at which the diamond heating temperature does not reach the value causing their oxidation, graphitization or deformation due to temperature stresses.</p>
