“中文热”在匈牙利行之有年,既有深厚的历史文化渊源,也有丰富的现实生活土壤。中匈两国传统友好,随着匈牙利“向东开放”战略与共建“一带一路”倡议紧密对接,越来越多中资企业到匈投资发展,两国人文交流也更加密切。对当地人来说,中文学习的重要性与日俱增。席立松学习中文15年,对他的人生产生了巨大的影响。他认为学习一门语言不是一场短跑,而是一场马拉松,需要持续的努力和热情。

作者： attila R.Imre KFKI Atomic Energy Research Institute H-1525 Budapest POB 49 Hungary

In this paper we would like to give a brief review about the extensibility of the liquid-liquid locus into the negativepressure region. Negative pressure states are hardly explored; most researchers believe that the pressure scale ends at p = *** would like to show that this is not true, the p = 0 point is not a special point for liquids, it can be 'easily' crossed. We aregoing to give a few example, where the extension of liquid-liquid locus for polymer blends and solutions below p = 0 givesus some interesting results, like the merging of UCST and LCST branches in weakly interacting polymer solutions or thereason why most UCST blends exhibit pressure induced immiscibility. Also, we will see what happens with the immiscibilityisland of aqueous polymer solutions when -- reaching the critical molar mass -- it 'disappears'.
