STUDIES ON TBP-NO_x——A NEW OXIDIZING AGENT PREPARED FROM NITROGEN OXIDES

Nitrogen oxides(NO_2 and NO)are absorbed by tributyl phosphorate(TBP)to fom a new complex mixture of TBP-NO_x. which is used as a selective oddizing agent to oxidize benzylalcohols to corresponding sldehydes or ketones In high yield. In the reaction process, nitrogen oxides are llberated mildly and mainly reduced to nitrogen, while tributyl phosphorate is recovered end recycled.

Synchrotron X-Ray Diffraction Studies on the New Generation Ferromagnetic Semiconductor Li(Zn,Mn)As under High Pressure

The pressure effect on the crystalline structure of the I-II- V semiconductor Li（Zn,Mn）As ferromagnet is studied using in situ high-pressure x-ray diffraction and diamond anvil cell techniques.

论新中国史研究与“新中国学”

今年是中华人民共和国成立75周年。75年来特别是中共十八大以来,中国特色社会主义进入新时代,党领导人民全面建成小康社会,乘势开启实现第二个百年奋斗目标新征程。新中国的历史发展,是历史中国的延续和发展,中国式现代化由奠基、开创到深化和拓展,中华民族从站起来到富起来再到强起来,中华文明实现生命更新和现代转型。新中国的历史发展,不断孕育、生成和发展关于新中国的认识和研究,即“新中国学”。“新中国学”特指关于中华人民共和国之学,由此也推动中国学从“他塑”转向“自塑”,重心从研究中国传统历史文化转向探讨关于新中国的历史、社会和时代发展,以及新中国与世界的关系。“新中国学”是一个复杂的系统学科,是关于新中国的“百科全书”;作为世界中国学的重要组成部分,在向世界传播中国精神、中国价值、中国力量方面发挥着重要作用。加快构建“新中国学”的学科体系、学术体系和话语体系,推动引领世界中国学发展,是推进新中国史研究的学科建设要求,也是推动哲学社会科学讲好中国故事、传播好中国声音的时代要求。为此,我们与河北学刊杂志社共同策划了本组专题讨论,重点以《论新中国史研究与“新中国学”》《新中国史史料学的新境遇与新问题--兼论“新中国学”资料构建的发展性与实践性》为题作多方面探讨,以期引领和推动“新中国学”研究不断向纵深发展。

中原学离新时代中国学、世界中国学还有多远

中原文化、黄河文化是中华文明总进程的核心和引领者。担负新时代新的文化使命,建设中华民族现代文明,创造人类文明新形态,要求我们从构建中国自主知识体系的高度来定位、研究中原文化、黄河文化,推进中原文化、黄河文化的学问化、学术化、学科化、学派化表达,不断提升中华文化的影响力。在新时代中国学、世界中国学视野下,中原学要确立中华民族现代文明、人类文明新形态两个研究方向,回答好习近平新时代中国特色社会主义思想是中华文化和中国精神的时代精华、中国道路与中华文明道路的关系、在中国式现代化的基础上深化中原学研究、推动中原学的国际化表达等四个核心问题。如此,中原学才能超越地域范畴,从中原之学走向中国之学、世界之学。
