Journal of Differential Equations was founded in 1965 and is published by Elsevier under the Academic Press imprint, with editorial correspondence handled from San Diego.《Journal of Differential Equations》创刊于 1965 年，由 Elsevier 以 Academic Press 的名义出版，编辑通信从圣迭戈发出。
The scope is stated in a single sentence. The journal concerns the theory and the application of differential equations, and its readers are meant to include engineers and physicists as well as mathematicians.范围用一句话说完。刊物管微分方程的理论与应用，读者既包括数学家，也包括工程师与物理学家。
Five areas are named on the publisher's page. Control theory and ordinary equations take two of them, partial equations and stochastic equations another two, and topological dynamics closes the list.出版方页面点了五个方向。控制理论与常微分方程占两头，偏微分方程与随机微分方程各占一头，拓扑动力系统收尾。
Dispersive equations carry a large share of recent issues. Nonlinear Schrödinger problems turn up with soliton stability, multi-soliton interaction and well-posedness in weighted spaces.色散方程占了近几期的一大块。非线性薛定谔问题反复出现，涉及孤子稳定性与多孤子相互作用，加权空间中的适定性也有人做。
Integrable structure is a standing interest, with inverse scattering for Zakharov–Shabat operators, peakon dynamics in Camassa–Holm variants and universality in the small-dispersion limit of the modified KdV hierarchy.可积结构是长期兴趣。Zakharov–Shabat 算子的逆散射有人处理，Camassa–Holm 变体里的峰子动力学有人研究，修正 KdV 层级在小色散极限下的普适性也有人写。
Fluid limits come in families. Small Mach number limits for elastodynamics, low Deborah number limits for Vlasov–Fokker–Planck systems coupled to magnetohydrodynamics, and zero-viscosity limits for chemotaxis–Navier–Stokes all appear within a few volumes.流体极限成组出现。弹性动力学的小马赫数极限是一组，与磁流体耦合的 Vlasov–Fokker–Planck 系统的低德博拉数极限是另一组，趋化–纳维–斯托克斯方程的零粘性极限又是第三组，几组都挤在相邻的卷次里。
Elliptic and variational work supplies the steady-state half. Choquard ground states and Trudinger–Moser inequalities each have a run of papers, and concavity estimates for Hessian quotient equations sit alongside singular quasilinear problems.椭圆与变分论文构成刊物的定态一半。肖夸尔方程的基态与特鲁丁格–莫泽不等式各有连着的几篇，海森商方程的凹性估计与奇异拟线性问题放在一起。
Biological models are frequent enough to count as a genre. Predator-prey Lotka–Volterra systems, chemotaxis with nutrient consumption, tumour free boundaries and cholera in advective environments all have recent representatives.生物模型多到可以算一个门类。捕食者与被捕食者的 Lotka–Volterra 系统、带营养消耗的趋化模型、肿瘤自由边界问题、流动环境中的霍乱传播，近几期各有代表。
Spectral and geometric questions run alongside. Periodic Sturm–Liouville gaps, conformal spectral bounds on manifolds, Monge–Ampère systems and curvature flows on pinched Hadamard surfaces appear in the same stretch of volumes.谱论与几何问题并行。周期 Sturm–Liouville 问题的谱隙、流形上的共形谱界、蒙日–安培系统与哈达玛曲面上的曲率流，落在同一段卷次里。
Dynamical systems theory keeps its own corner. Averaging for discrete systems, limit cycles of Abel equations, Filippov systems without sliding regions and geodesic flows on non-compact manifolds all have papers here.动力系统理论有自己的角落。离散系统的平均法、阿贝尔方程的极限环、没有滑模区的菲利波夫系统、非紧流形上的测地流，都能找到对应的论文。
Free-boundary and inverse problems are treated as one subject. Stefan problems, inverse Stefan problems and inverse scattering for Zakharov–Shabat operators appear close together.自由边界与反问题被当成同一件事。斯特藩问题、斯特藩反问题与 Zakharov–Shabat 算子的逆散射，常在同一批论文里相邻。
Articles carry article numbers instead of page ranges. Volume 489 alone runs through numbers in the 114840s to the 114890s.论文用文章编号代替页码范围。单是第 489 卷，编号就从 114840 段排到 114890 段。
Nothing in the deposit suggests themed issues. There are no special-issue titles in the sample, and the Editorial Board page is the only recurring item that is not a research paper.存档里看不出专辑的痕迹。样本中没有专辑标题，反复出现的非研究条目只有编委页。
History
Volume 1, issue 1 appeared in 1965, and its contents were four research papers and an Editorial Board page.第 1 卷第 1 期在 1965 年问世，内容是四篇研究论文加一页编委名单。
The first papers are recognisable problems of the period, on exterior Dirichlet problems, comparison theorems for second-order equations, regular degeneration of singularly perturbed systems and the characteristic matrix of matrix differential operators.首卷的题目是那个年代的典型问题，涉及外狄利克雷问题、二阶方程的比较定理、奇异摄动系统的正则退化，以及矩阵微分算子的特征矩阵。
Academic Press published the journal from the start, and the imprint survived the company's absorption into Elsevier, which is why the citation records carry both names.从创刊起出版方就是 Academic Press，这家公司并入 Elsevier 之后名义保留下来，引文著录因此两个名字都写。
The deposit holds 15,224 records. That is a modest figure for sixty-one years because the journal prints no book reviews and very little front matter.存档共 15,224 条记录。对六十一年来说不算多，原因是这份刊物不发书评，前置页也极少。
Volume numbers stopped following the calendar. Volume 489 carries papers dated 2026 and 2027, and volumes 483 to 489 all belong to the current year's production.卷号早就不跟年份走了。第 489 卷里既有 2026 年也有 2027 年的论文，第 483 到第 489 卷都属于眼下这一年的产出。
The move to continuous volumes came with the loss of issue numbers. Every 2026 record in the deposit has an empty issue field.改成连续卷次的同时也放掉了期号。2026 年的记录在期号一栏全是空的。
Impact flattened after a rise. The factor was 2.43 in 2021 and 2.615 in 2022, then 2.4 in 2023 and 2.3 in both 2024 and 2025.影响因子涨过一轮后走平。2021 年是 2.43，2022 年 2.615，2023 年 2.4，2024 与 2025 都是 2.3。
The five-year factor is 2.8, above the current figure, which is what a long half-life looks like in arithmetic.五年影响因子是 2.8，高于当年值，长半衰期在算术上就是这个样子。
That half-life is 9.7 years and the citation base is 27,103, so most citations arrive well after publication.半衰期是 9.7 年，引用基数 27,103，多数引用在出版很久之后才到。
Journal Citation Reports ranks the title 28th of 492 in mathematics, a percentile of 94.4, and the JCI rank is higher still at 17 of 492.引文报告把它排在数学类 492 种里的第 28，百分位 94.4，JCI 排名更高，是 492 种里的第 17。
Output is large for a specialist journal. The 2025 count is 817 articles, and an immediacy index of 0.5 confirms that new papers are not where the citations come from.对一份专门刊物来说产量很大。2025 年记了 817 篇，即时指数 0.5 说明引用并不来自新论文。
Gold open access is 20.05 percent, so a fifth of the output is free at publication and the rest sits behind subscription.金色开放获取占 20.05%，也就是五分之一在出版时即可免费读到，其余仍在订阅墙后。
The archive has no gap years and the title has never changed. Sixty-one years of continuous volume numbering is the whole history.存档没有断年，刊名也从未改过。六十一年连续编号就是它的全部历史。
Editors
Four editors-in-chief share the title. Adrian Constantin of the University of Vienna and Kening Lu of Brigham Young University are listed first, with John Mallet-Paret of Brown University and Wei-Ming Ni of the Chinese University of Hong Kong beside them.主编署名四人并列。维也纳大学的 Adrian Constantin 与杨百翰大学的 Kening Lu 排在前，布朗大学的 John Mallet-Paret 与香港中文大学的 Wei-Ming Ni 紧随其后。
Constantin's listed interests are free boundary problems, wave motion, integrable systems, geometric mechanics and dynamical systems, which maps closely onto what the journal prints.Constantin 名下写的研究兴趣包括自由边界问题与波动，可积系统与几何力学也在其中，最后一栏是动力系统，与刊物实际发表的东西贴得很近。
The board is long, and its members come from analysis, partial differential equations and dynamical systems in roughly equal measure.编委会名单很长，成员大致平均地来自分析、偏微分方程与动力系统三块。
Gang Bao of Zhejiang University is on it, and so are Henri Berestycki and Alberto Bressan of Pennsylvania State University.浙江大学的包刚在名单上，亨利·贝雷斯蒂茨基与宾夕法尼亚州立大学的阿尔贝托·布雷桑也在。
Handling runs through Elsevier's Editorial Manager, where the journal is filed under the code YJDEQ, and the correspondence address stays at the San Diego office.稿件处理走 Elsevier 的 Editorial Manager，刊物在那里的代号是 YJDEQ，通信地址仍是圣迭戈的办公室。
Authors report roughly eight months from submission to a decision, long even by mathematics standards, and the volume of submissions explains part of it.作者端普遍报告从投稿到有结果约八个月，按数学界的标准也算长，来稿量可以解释其中一部分。
Desk work is heavy at this scale. Four editors-in-chief with a board of this size carry more than eight hundred published papers a year, before the rejected manuscripts are counted.这个体量下案头工作很重。四位主编配一张这样的名单，一年要推出八百多篇论文，被拒的稿子还没算进去。
The Editorial Board page is deposited as an item in each volume, which makes the masthead readable from the record without the publisher's site.编委页会作为条目存进每一卷，不靠出版方网页也能从记录里读到名单。
The 1965 board page survives the same way, so the first masthead sits in the deposit beside the first papers.1965 年的编委页也这样保存下来，最早的名册与最早的论文一起留在存档里。
Refereeing carries the weight of a journal that prints long proofs. A manuscript arrives as a complete argument, and the report is mainly about whether the argument holds.评审要担起一份印长篇证明的刊物的分量。来稿带的是完整论证，审稿意见主要判断论证成不成立。
Scope decisions rest with the editors rather than with a fixed section structure. There is no reviews section, so a survey has to earn its space against research papers.选题由编辑决定，不靠固定栏目。刊物没有综述栏目，综述要和研究论文争版面。
The four editors-in-chief sit in Vienna, Provo, Providence and Hong Kong, which leaves three time zones between them and the San Diego office.四位主编分别在维也纳、普罗沃、普罗维登斯与香港办公，与圣迭戈编辑部的时差从一小时到十几小时不等。
