Editors’ Note

The Journal of Ancient Civilizations (JAC) is published annually in two fascicles by the Institute for the History of Ancient Civilizations (IHAC, Northeast Normal University, Changchun, Jilin Province, People’s Republic of China).

The aim of JAC is to provide a forum for the discussion of various aspects of the cultural and historical processes in the Ancient Near Eastern and Mediterranean world,encompassing studies of individual civilizations as well as common elements, contacts and interactions among them (e.g. in such traditional fields as Assyriology, Hittitology,Egyptology, Classics, and Sinology among others). Hence, we publish the work of international scholars while also providing a showcase for the finest Chinese scholarship,and so welcome articles dealing with history, philology, art, archaeology and linguistics that are intended to illuminate the material culture and society of the Ancient Near East,the Mediterranean region, and ancient China. Articles discussing other cultures will be considered for publication only if they are clearly relevant to the ancient Mediterranean world, the Near East and China. Information about new discoveries and current scholarly events is also welcome. Publishers are encouraged to send review copies of books in the relevant fields.

JAC is a double blind peer-reviewed journal. All submitted articles are first carefully read by at least two editors of JAC, who will give a feedback to the author. Articles(excluding book reviews or research reports) are afterwards reviewed anonymously by at least two referees in the specific field, appointed by the editorial board. In cases where the reviewers recommend changes in the manuscript, authors are requested to revise their articles. From time to time, we will publish a list of the referees to make the double blind peer-review process transparent and comprehensible.

The double blind peer-reviewed articles of this fascicle cover a wide range of topics.First, Michela Piccin deals with the expressions of mortality in Akkadian texts. David A. Falk’s contribution anchors in this topic by studying decay in Egyptian culture while Mohamed Gamal Rashed presents his detailed ideas on the future exhibition program for the Egyptian Museum in Cairo. Finally, Houliang Lü examines the historian Polybius,well-known for his pragmatic history-approach, in terms of dramatic elements in The Histories, which contribute substantially to the coherence and connectivity of the work.Such connectivity and entanglement from a perspective of global history are, finally, in the focus of the bibliographical survey, written by Raimund Schulz and Uwe Walter, and the review of a recent book on the Silk Road(s) by Xueliang Shi.

MWJ-2418智能门窗保温性能试验机的基本原理为标定热箱法测定传热系数，热箱内的电加热器散热量为总热量，将总热量减去热箱向环境空间的散热量和试件框的热损失，即为热箱热量通过试件向冷箱传递的热量.根据两侧传热量、两侧空气温度以及试件面积，便可求得传热系数K值.
