Description

ни . Тепло от нагреваемой электрическим током константа овой проволоки радиально проходит через слой исследуемого вещества. После достижепи  теплового равновеси  измер ютс  сила тока и падение напр жени  на измерительном участке 2, дл  вычислени  количества тепла, проход щего через слой исследуемото вещества.neither Heat from an electric current heated constant wire radiates radially through the layer of the test substance. After thermal equilibrium is reached, the current and voltage drop across measurement section 2 are measured to calculate the amount of heat passing through the layer of the test substance.

За счет выполнени  концевых участков 3 из сверхпроводника отсутствует выделение джоулева тепла, так как сопротивление сверхпроводника в сверхпровод щем состо нии равно нулю.Due to the completion of the end sections 3 of the superconductor, there is no release of Joule heat, since the resistance of the superconductor in the superconducting state is zero.

Поскольку теплопроводность концевых участков 3 в сверхпровод щем состо нии во много раз меньше теплопроводности металла, например, конста тана, то отвод тепла концевыми участками будет практически отсутствовать , ввиду этого дл  устранени  потери тепла , отводы 4, измер ющие паденне напр жени , подсоедин ютс  к концевому участку вне измерительной -части капилл ра.Since the thermal conductivity of the end sections 3 in the superconducting state is many times less than the thermal conductivity of the metal, for example, is constant, the heat removal by the end sections will be practically absent, therefore, to eliminate heat loss, the outputs 4 measuring the drop voltage are connected to the end section outside the measuring part of the capillary.

Преимущество предложенного устройства g том, что значительно уменьшаютс  потери топла от концевых участков и отводов, измер ющих падение напр л ени , и устран етс  процесс расчета этих потерь.The advantage of the proposed device g is that the losses of fuel from the end sections and outlets measuring the voltage drop are significantly reduced, and the process of calculating these losses is eliminated.
