Analysis and Applications is World Scientific's journal for analysis that has somewhere to go, founded in 2003 and published eight times a year.《Analysis and Applications》是 World Scientific 的应用分析刊物，2003 年创刊，一年八期。
The publisher's statement is precise about the filter. The journal takes analysis that has direct or potential applications to the physical and biological sciences and to engineering.出版方的说明把这个筛子写得很清楚。刊物收的是对物理科学、生物科学与工程有直接或潜在应用的分析学。
The aim is phrased as encouraging new techniques and results in applied analysis, which puts method ahead of subject classification.宗旨写的是鼓励应用分析中的新技术与新结果，方法因此排在学科分类之前。
Seven topics are named. Approximation theory comes first, and asymptotic analysis follows it.点名的题目有七个。逼近论排在最前，渐近分析紧随其后。
Integral equations and integral transforms make up the next pair, and ordinary and partial differential equations the pair after that.积分方程与积分变换是接下来的一对，常微分方程与偏微分方程又是下一对。
Delay differential equations and perturbation methods close the list, and the order says something about where the editors see the centre of the field.时滞微分方程与摄动方法收尾，这个次序大致说明了编委把重心放在哪里。
Approximation is heavily represented in recent issues. Short exponential sums with geometric error decay, dimension-independent approximation on Riemannian manifolds and neural network operators for integrable functions all appear.逼近在近几期占得很多。误差按几何速度衰减的短指数和逼近、黎曼流形上与维数无关的函数逼近、用于可积函数的神经网络算子，都出现了。
Sampling and frames form a sub-genre. Gabor frames built from a direct sum decomposition, framelets with a general dilation matrix and semi-discrete sampling in Sobolev–Orlicz spaces are all present.采样与框架构成一个小门类。用直和分解构造的 Gabor 框架、带一般伸缩矩阵的框架小波、Sobolev–Orlicz 空间中的半离散采样都有。
Partial differential equations are handled with an eye on limits and regularity. Martingale solutions of a chemotaxis-fluid system, ill-posedness and inviscid limits in Besov spaces and global Lorentz-type regularity for non-convex fully nonlinear elliptic equations appear inside one year.偏微分方程的处理盯着极限与正则性。趋化–流体系统的鞅解、Besov 空间中的不适定性与无粘极限、非凸完全非线性椭圆方程的全局洛伦兹型正则性，都在一年内出现。
Variational problems supply the steady second half. Choquard equations, fractional Kirchhoff problems and double phase problems with critical growth recur across issues.变分问题构成稳定的另一半。肖夸尔方程与分数阶基尔霍夫问题常有，临界增长的双相问题也不止一次露面。
Harmonic analysis supplies the technical core. Riesz transform commutators on Besov spaces, weighted Steklov eigenvalue problems and discrete fractional maximal operators are all treated.调和分析提供技术内核。Besov 空间上的 Riesz 变换交换子、加权 Steklov 特征值问题与离散分数次极大算子都有人处理。
Learning and numerics have moved in. Outcome weighted learning, mirror descent on manifolds and regret bounds for Kaczmarz algorithms appear beside the classical analysis.学习与数值方法已经进来。结果加权学习、流形上的镜像下降与 Kaczmarz 算法的遗憾界，与经典分析并排出现。
Special functions have been a fixture from the start. Uniform asymptotic expansions with error bounds for hypergeometric and Whittaker functions appear in the earliest volumes, and the same kind of paper still turns up in 2026.特殊函数从一开始就是常客。超几何函数与惠特克函数的带误差界一致渐近展开最早几卷就有，同类的稿子 2026 年仍在出现。
The two normalised measures sit close together. The JCI is 1.59 with a rank of 29 of 492 in mathematics, and the article influence score falls in the first quartile of both categories.两套归一指标彼此贴得很近。JCI 是 1.59，数学类 492 种里排第 29，文章影响力得分在两个类目都落在第一分位。
Each volume closes with an author index. Volume 24 ends with one at issue 8, and it is the only recurring item in the deposit that is not a research paper.每卷以作者索引收尾。第 24 卷的索引在第 8 期，这也是存档里唯一反复出现的非研究条目。
History
Volume 1 appeared in 2003 and volume 24 covers 2026, so the numbering has tracked the calendar without a break.第 1 卷在 2003 年出版，第 24 卷对应 2026 年，卷号一直跟着年份走，没有断过。
Volume 1 carried four issues and ended with an author index, a closing item the journal has kept in every volume since.第 1 卷只有四期，末尾排了一份作者索引，此后每一卷都保留了这个收尾条目。
The opening issue set the tone. Alongside asymptotic expansions for hypergeometric functions it carried a paper by Smale and Zhou on estimating the approximation error in learning theory, which put statistical learning inside the scope in the first year.创刊号已经定下基调。除了超几何函数的渐近展开，那一期还有 Smale 与周定轩讨论学习理论中逼近误差估计的论文，统计学习从第一年就进了范围。
Roderick S. C. Wong held the title of co-editor-in-chief from 2003 to 2012, which puts a two-editor structure at the founding.Roderick S. C. Wong 在 2003 至 2012 年间担任共同主编，创刊期就是两位主编并列的架构。
The archive is small. There are 835 records in total, and the journal publishes about 92 articles a year.存档很小。全部记录只有 835 条，一年发表约 92 篇。
Early volumes ran to four issues a year and the current ones to eight, which is the schedule the annual output has to fit.早期每卷四期，如今每卷八期，一年的产量要在这样的日程里安排。
The earliest deposit sets titles in full capitals, a typographic convention that later volumes dropped.最早的存录取题全用大写字母，此后的卷次放弃了这个做法。
Article identifiers sit inside the DOI, in the form 10.1142 followed by an ISSN-derived stem whose sequence opens with s02195305.文章标识藏在 DOI 里，前缀 10.1142 之后接由刊号派生的字串，序列以 s02195305 开头。
Online-first publication runs ahead of issue assignment. Seventy-four of the hundred most recent records carry no volume or issue number yet.在线优先出版跑在期号前面。最近一百条记录里有七十四条还没有卷号与期号。
The impact factor climbed slowly and then settled. It was 1.79 in 2021, 1.956 in 2022 and 2 in 2023, then 2.4 in 2024 and 2.3 in 2025.影响因子慢慢爬上去然后停住。2021 年是 1.79，2022 年 1.956，2023 年 2，2024 年 2.4，2025 年 2.3。
Two categories carry the title. It ranks 28 of 492 in mathematics with a percentile of 94.4, and 54 of 345 in applied mathematics with 84.5.两个类目都收这份刊物。数学类 492 种里排第 28，百分位 94.4，应用数学类 345 种里排第 54，百分位 84.5。
The citation base is 968 and the half-life 5.3 years, so the factor rests on a small pool of fairly recent papers.引用基数是 968，半衰期 5.3 年，这个因子靠的是一小池不算久远的论文。
Gold open access is 1.11 percent. Subscription carries the journal and no article fee is charged to authors.金色开放获取占 1.11%。刊物靠订阅维持，不向作者收文章处理费。
Abstracting follows the two categories rather than the publisher's catalogue, which is how a small journal ends up near the top of a large field.收录跟着两个类目走，不按出版方目录走，一份小刊物因此出现在一个大领域的高处。
Editors
The editorial structure started as a co-editorship, and the journal has kept a small masthead since.编辑架构从两位主编并列开始，此后名册一直不大。
Roderick S. C. Wong held the co-editor-in-chief title for the first decade, and his own record lists the appointment from 2003 to 2012.Roderick S. C. Wong 在头十年担任共同主编，他的履历把任期写作 2003 至 2012 年。
A journal of ninety-odd papers a year does not need a large board. The handling load comes to a few manuscripts a month per editor at most.一年九十来篇的刊物不需要大名单。摊到每位编辑头上，一个月顶多几篇稿子。
Eight issues a year set the production calendar. Each issue closes on a fixed date and the volume ends with an author index.一年八期定下生产日历。每期按固定日期收官，全卷以作者索引结束。
Online-first publication carries most of the load, and the gap between acceptance and issue assignment is where the queue actually sits.在线优先承担了大部分负载，录用与排期之间的那段间隔，才是稿件真正排队的地方。
The two categories pull in different directions. A paper has to satisfy readers in analysis and in applied mathematics at the same time.两个类目拉扯的方向不同。一篇论文要同时让分析方面的读者与应用数学方面的读者满意。
New techniques are the stated preference, which explains why a paper that introduces a method often outranks one that sharpens an existing estimate.编辑偏好写在宗旨里，偏的是新技术，所以提出方法的论文往往比改进既有估计的论文更受青睐。
No article fee means no billing step in the workflow. Decisions rest on review, and there is no author-pays queue.不收文章处理费，流程里就没有结算那一步。判断只靠评审，也没有作者付费的队列。
The journal sits in World Scientific's mathematical analysis cluster, beside titles on wavelets and on contemporary mathematics.刊物在 World Scientific 的数学分析这一簇里，旁边是讲小波与当代数学的几种刊。
Front matter is deposited with the issue, and the author index is the only editorial page that survives in the record.前置页随期存入，作者索引是记录里唯一留下来的编辑页。
Handling editors answer for a scope that runs from approximation theory to stochastic partial differential equations, a wide brief for a small masthead.经手的编辑要对一个从逼近论到随机偏微分方程的范围负责，名册不大而范围很宽。
The acceptance lag decides the rest. A paper accepted in a good month still waits for the issue that matches its place in the volume.剩下的由排期决定。在顺利的月份录用的稿子，仍要等到与它在卷中位置相符的那一期。
