中文摘要：

量在一个目标上探查的热力学的影响被学习。这里，量探查被理解基于一个非拆毁相互作用是测量前，它记录探查的目标的一些信息，但是当探查的仪器和探查的目标从环境被孤立时，不改变它的精力状态。当探查的仪器和探查的对象沉浸于一样的平衡环境时，探查能影响对象的有效温度或导致量，这被说服为到转移的对象的等温的过程它的精力。这个热力学的特征能被认为是量探查的一个证人。

英文摘要：

The thermodynamic influence of quantum probing on an object is studied. Here, quantum probing is understood to be a pre-measurement based on a non-demolition interaction, which records some information of the probed object but does not change its energy state when both the probing apparatus and the probed object are isolated from the environment. It is argued that when the probing apparatus and the probed object are immersed in the same equilibrium environment, the probing can affect the effective temperature of the object or induce a quantum isothermal process for the object to transfer its energy. This thermodynamic feature can be regarded as a witness of quantum probing.
