結晶學學報A輯：基礎與進展發表文章，報告最廣泛意義上結晶學所有領域的理論與實踐進展。除了傳統的結晶學，這包括納米晶體、超晶體、非晶材料、準晶體、同步加速器和xfel研究、相干散射、衍射成像、時間分辨研究以及材料的應變和缺陷結構。該期刊分為兩部分：快速出版推進部分和傳統基礎部分。預付款部分的文章具有特別高的價值和影響。他們得到了迅速的治療，并可能通過一篇附帶的科學評論文章和一篇新聞稿加以強調。更多細節見2013年11月的社論。該期刊的中心主題一方面：屬性和安排的實驗和理論研究原子、離子和分子凝聚態、周期、準周期的或非晶態、理想的或真實；另一方面：理論和實驗方面的各種方法來確定這些屬性和安排。我們期待收到您的提交。

Acta Crystallographica Section A: Foundations and Advances publishes articles reporting advances in the theory and practice of all areas of crystallography in the broadest sense. As well as traditional crystallography, this includes nanocrystals, metacrystals, amorphous materials, quasicrystals, synchrotron and XFEL studies, coherent scattering, diffraction imaging, time-resolved studies and the structure of strain and defects in materials.The journal has two parts, a rapid-publication Advances section and the traditional Foundations section. Articles for the Advances section are of particularly high value and impact. They receive expedited treatment and may be highlighted by an accompanying scientific commentary article and a press release. Further details are given in the November 2013 Editorial.The central themes of the journal are, on the one hand, experimental and theoretical studies of the properties and arrangements of atoms, ions and molecules in condensed matter, periodic, quasiperiodic or amorphous, ideal or real, and, on the other, the theoretical and experimental aspects of the various methods to determine these properties and arrangements.We look forward to receiving your submissions.
