<p class="Abstract">The Ar flow rate effect on the electrical and optical properties of the sputtered Al-doped ZnO thins films were investigated. It was shown that a strong X-ray peak from (002) and (004) planes is dominant, suggesting that most grains have <em>c</em>-axis perpendicular to the substrate surface. The (002)-ZnO and (004)-ZnO peaks were measured at 2q = 34.12<sup>0</sup>, and 71.85<sup>0</sup>, respectively. It was also found that the growth rate of the Al-doped ZnO thin films increases when the sputtering power is increased. The transmittance of these film are strongly dependent on the sputtering power with the maximum transmittance of 92% was obtained at the sputtering power of 150 W and 50 sccm of Ar flow rate. The resistivity of the films is decreases as the Ar flow rate is increased. The lowest resistivity of 9.74 x 10<sup>-4</sup> W.cm was obtained at the films with Ar flow rate of 80 sccm. The mobility increases with the Ar flow rate increases. The carrier concentration also indicates the same pattern as the mobility. The transmittance of Al-doped ZnO thin films is also strongly dependent on the Ar flow rate. It was also observed the variation of contact resistivity of Al/Ti/Al to Al-doped n-ZnO thin films. The specific contact resistivity <em>r<sub>c</sub></em> of 1.8x10<sup>−5</sup> W.cm<sup>2</sup> was obtained at 150 nm-thick Al.</p>

В работе представлен способ расчета термограммы для квазистационарной работы скважины. Установлено влияние дебита потока на возникающий тепло-обмен с окружающими горными породами. Результаты работы могут быть использованы для анализа профиля температуры в зависимости от расхода скважины. The paper presents a method for calculating a thermogram for quasi-stationary well operation. The influence of the flow rate on the resulting heat exchange with the surrounding rocks is established. The results of the work can be used to analyze the temperature profile depending on the well flow rate.
