西雅尔多表示，匈牙利和塞尔维亚铁路公司将轮流运营列车，匈牙利国家铁路公司（MÁV）将运营现代化的欧洲城际列车，同时，“我们热切期盼塞尔维亚铁路公司超现代化的、由中国制造的柴油列车投入运营”。他表示，匈塞双方已达成一致，将尽可能减少火车在边境口岸的停留，边境和海关检查将在途中进行，从而将两个首都之间的旅程时间缩短至约三小时。
Often people write these metrics as \(ds^2 = \sum_{i,j} g_{ij}\,dx^i\,dx^j\), where each \(dx^i\) is a covector (1-form), i.e. an element of the dual space \(T_p^*M\). For finite dimensional vectorspaces there is a canonical isomorphism between them and their dual: given the coordinate basis \(\bigl\{\frac{\partial}{\partial x^1},\dots,\frac{\partial}{\partial x^n}\bigr\}\) of \(T_pM\), there is a unique dual basis \(\{dx^1,\dots,dx^n\}\) of \(T_p^*M\) defined by \[dx^i\!\left(\frac{\partial}{\partial x^j}\right) = \delta^i{}_j.\] This extends to isomorphisms \(T_pM \to T_p^*M\). Under this identification, the bilinear form \(g_p\) on \(T_pM \times T_pM\) is represented by the symmetric tensor \(\sum_{i,j} g_{ij}\,dx^i \otimes dx^j\) acting on pairs of tangent vectors via \[\left(\sum_{i,j} g_{ij}\,dx^i\otimes dx^j\right)\!\!\left(\frac{\partial}{\partial x^k},\frac{\partial}{\partial x^l}\right) = g_{kl},\] which recovers exactly the inner products \(g_p\!\left(\frac{\partial}{\partial x^k},\frac{\partial}{\partial x^l}\right)\) from before. So both descriptions carry identical information;

YouGov表示，今年稍晚將重新進行調查，以再次檢驗這個主題。
哈尔滨初步形成了以冰刀、雪板、冰壶为主的冰雪运动装备体系和以索道、魔毯、造雪制冰设备为主的冰雪场地装备体系。哈尔滨市工业和信息化局副局长何景荣介绍，2025年全市重点监控冰雪装备企业主营业务收入同比增长42％。，详情可参考Line官方版本下载
