日欧协定凸显了推动区域贸易协定行动的新紧迫性随着美国总统唐纳德·特朗普引发的世界贸易战争危险升级,全球应对已变得紧迫。迄今为止,最好的建议来自亚洲经济体,它们提出了三项重要的贸易政策项目。这些都重申了国际贸易规则,并正在建立新的联盟,为一个规则化的贸易体系而战。亚洲的做法值得注意的理由是,它棋高一着地解决了与合作的冲突。最近的一次行动是,日本和欧盟于7月17日签署了一项大型、全面的经济伙伴关系协议(EPA)。

This paper reviews recent developments in digital switched hydraulics particularly the switched inertance hydraulic systems （SIHSs）. The performance of SIHSs is presented in brief with a discussion of several possible configurations and control strategies. The soft switching technology and high-speed switching valve design techniques are discussed. Challenges and recommendations are given based on the current research achievements.

We have utilized second harmonic generation （SHg） to disentangle the coupled first-order charge order/structural transition at Tc ~ 281 K in the transition-metal dichalocogenide IrTe2, an exceptional layered material with 3D properties. The data from SHg shows extremely sharp transition in both the cooling and warming processes with less than 0.2 K transition window. Surface electronic symmetries of Car and S2 are observed in the high temperature and low temperature phases, respectively. Compared to neutron diffraction data for the structural transition （Phys. Rev. B 88 （2013）115122） and to the electrical resistivity for the microscopic transition （Phys. Rev. B 95 （2017）035148）, our data indicates the electronic transition at the surface is the precursor to the structural transition.
