Recently,a dual relation T_(0)(n+1)=T_(HP)(n)between the minimum temperature(T_(0)(n+1))black hole phase and the Hawking-Page transition(T_(HP)(n))black hole phase in two successive dimensions was introduced by Wei et al(2020 ***.D10210411);this was reminiscent of the anti-de Sitter/conformal field theory(AdS/CFT)correspondence,as the Hawking-Page transition temperature could be treated as the temperature of the dual physical quantity on the boundary and the latter corresponds to that in the *** this paper,we discuss the Hawking-Page transition and the dual relations in Ads black holes surrounded by dark energy in general *** findings reveal the occurrence of the Hawking-Page transition between the thermal AdS radiation and thermodynamically stable large AdS black holes,in both the spacetime surrounded by phantom dark energy and the spacetime surrounded by quintessence dark *** discuss the effects of the phantom dark energy and quintessence dark energy on the Hawking-Page transition *** the dual relation in particular,it works well for the case of an AdS black holes surrounded by phantom dark *** the case of an Ads black hole surrounded by quintessence dark energy,the dual relation should be modified under an open assumption that the state parameter and the density parameter of the quintessence dark energy depend on the dimensions of the spacetime.

"为所当为"作为森田疗法的行动指南在业内已广为知晓,"为所乐为"本身不是什么新鲜的话题,但在心理治疗领域如何帮助患者做到,如何使之对疾病的康复起到积极作用,从理论到实践都需要进一步探讨。例如,有的神经症患者并不是什么爱好也没有,即便在疾病的发生过程中和患病期间,有些爱好也能相对保持,但"乐为"的积极体验,如何能与疾病相关的痛苦体验整合在一个人身上,从而走向或保持一个完整的、既有现实痛苦又有积极一面的相对健康的人,而不是被神经症性痛苦纠缠陷入病态不能自拔的人?痛苦的、甚至是创伤性的体验,如何向正常记忆转化而不成为自我加强的病态的源泉(情结)?这其中"乐为"的积极体验能起到什么作用?为此,我们邀请了相关领域的专家作了评论,与原作者的论述一同刊出,希望引发相关的学术讨论。欢迎业内人士积极献言,我们将组织富于启发意义的来信来稿,做好后续编辑刊出工作,为大家提供一个学术讨论与争鸣的平台。
