Based on the principle by which the top temperature of the bubbles has to be higher than the temperature of thermodynamic equilibrium, the contact period is determined. 再根據汽泡頂點(diǎn)溫度必須高于熱力平衡溫度的原則，確定了接觸周期，該計算分析結果與文獻所給出的實(shí)驗數據吻合較好。
In thermal equilibrium, on the other hand, a system is far from static. 而在熱平衡情況下，系統遠非處于靜止狀態(tài)。
Precise thermodynamic equilibrium may never be achieved in a microscopic realm within gaseous nebulae. 精確的熱動(dòng)平衡永遠不會(huì )在氣體星云的一個(gè)微觀(guān)范圍內達到。
