The journal belongs to the Institute of Mathematics and its Applications, a professional body in Southend-on-Sea that runs a portfolio of eight titles. Oxford University Press prints and distributes it.刊物归数学及其应用学会所有，这家设在滨海绍森德的专业团体名下共八种期刊。印制与发行交给牛津大学出版社。
The aims statement is short enough to quote whole. The journal publishes original contributions to all fields of numerical analysis, and articles treating the theory, development or use of practical algorithms, including the interactions between those aspects, are welcomed.范围说明短到可以整句引。刊物发表数值分析各领域的原创论文，凡涉及实用算法的理论、开发或使用，以及这几方面相互作用的稿子都收。
Surveys come under a separate heading. They are published occasionally rather than by schedule, so a year may pass with none.综述另列一类。它是偶发的，不按计划排，一年里一篇没有也正常。
The volume structure is stated in the same paragraph. One volume a year, four issues to the volume, in print and electronic form.卷的结构写在同一段里。一年一卷，每卷四期，纸本与电子本并行。
Coverage runs from analysis to computation. Recent titles include a second-order consistent splitting scheme, the Scott–Vogelius element with an iterated penalty method for inhomogeneous Dirichlet data, and an augmented subspace method for interior and clustered eigenvalues.覆盖范围从分析一直铺到计算。近期题目里有二阶相容分裂格式，有处理非齐次 Dirichlet 数据的 Scott–Vogelius 单元配迭代罚方法，还有算内部特征值与成簇特征值的增广子空间方法。
Approximation theory holds a steady place. Exponential convergence of Chebyshev polynomial approximation in several variables is the kind of paper the journal takes, and so is the end-condition analysis that spline constructions need.逼近论占着稳定的一块。多元 Chebyshev 多项式逼近的指数收敛，以及样条构造离不开的端点条件分析，都是这家刊物会收的稿子。
Optimisation appears through the algorithms it shares with numerical analysis. One recent paper monitors the convergence speed of PDHG so that the primal and dual step sizes can be set better.最优化是以共享算法的身份出现的。近期一篇论文监测 PDHG 的收敛速度，为的是把原始步长与对偶步长定得更准。
Stochastic problems are inside the boundary. Error bounds for full space-time splitting discretisations of semilinear stochastic partial differential equations ran recently, with the analysis of the splitting doing the work.随机问题也在边界之内。半线性随机偏微分方程的全时空分裂离散化误差界前不久刊出，出力的是分裂格式的分析。
Almost everything arrives online first. In the hundred most recent records, 99 carry no volume or issue number, and the one that does sits in volume 46 issue 4.几乎所有稿子先走线上。最近一百条记录里，99 条没有卷号也没有期号，唯一带卷期的那条落在第 46 卷第 4 期。
Length is not rationed. That volume 46 paper runs from page 1939 to page 1993, and the record carries no sign of it being split.篇幅不作配额。第 46 卷那篇从 1939 页排到 1993 页，记录上看不出它被拆成几篇。
Output is modest and steady. The citation report counts 134 articles for 2025, and Crossref holds 2,618 records since 1981.产出不大而稳定。引证报告给 2025 年记了 134 篇论文，Crossref 里自 1981 年起的记录共 2,618 条。
Teams are small by design. The hundred latest records average 2.64 authors, the largest has six, and eleven papers carry one name.团队按学科习惯就小。最新一百条平均 2.64 位作者，最多的一篇六位，还有十一篇只署一个人。
There is no clinical or experimental section. A paper has to make its case in analysis, in the algorithm, or in the numbers it reports, and a numerical experiment is evidence rather than a result in itself.这里没有临床栏目也没有实验栏目。论文要么在分析上站住，要么在算法上站住，要么在报出的数字上站住，数值实验是证据，本身不算结论。
PubMed has no record of the journal. It is a mathematics title, and its readers come to it through the citation indexes and the publisher's platform.PubMed 里没有这家刊物的记录。它是数学刊物，读者经由引文索引与出版方平台找过来。
History
Volume 1 appeared in 1981 and ran to four issues. The first item in the first issue was a one-page editorial at page 1.第 1 卷 1981 年出版，四期出齐。创刊号的第一条是第 1 页上的一页社论。
The opening volume was not a sampler. It carried Sanz-Serna on linearly implicit variable coefficient methods of Lambert–Sigurdsson type, a convergence analysis for the Korteweg–de Vries equation, and strict constrained Chebyshev approximation.创刊卷不是试水。里面就有 Sanz-Serna 论 Lambert–Sigurdsson 型线性隐式变系数方法的一篇，有 Korteweg–de Vries 方程的收敛性分析，也有严格约束下的 Chebyshev 逼近。
The same issue held end conditions for interpolatory quintic splines and the convergence of operator approximations at turning points. Two ends of the field, side by side in 1981.同一期里还有插值五次样条的端点条件，以及算子逼近在转向点处的收敛性。领域的两头，1981 年就并排放着。
The volume count has never jumped. Volume 46 is the 2026 volume, which is one volume for each year since 1981.卷号的步子从没乱过。第 46 卷就是 2026 年卷，从 1981 年起一年正好一卷。
Oxford University Press appears as the publisher on every sampled record, back to the first volume.在抽样到的每一条记录上，出版方都写着牛津大学出版社，一直回溯到第 1 卷。
The impact factor has been at 2.3 for two years running. Before that it was 2.4, and before that 2.3 and 2.713.影响因子连着两年是 2.3。再往前是 2.4，再往前是 2.3 与 2.713。
The five-year figure is 2.7, higher than the current year, and the cited half-life runs 8.6 years. Work here is read for a long time after it appears.五年影响因子 2.7，高出当年值，半衰期 8.6 年。这里的东西发表之后能被读很久。
The immediacy index is 0.3. Papers in this field are not cited in the month they appear, and the journal does not pretend otherwise.即时指数 0.3。这个领域的论文不会在见刊当月被引，刊物也没有把它粉饰成别的样子。
In its category the journal sits at 54 of 345 and at the 84.5th percentile of the impact factor distribution, with a first quartile position in the article influence score as well.在所属类目里它排 345 种刊物的第 54 位，影响因子百分位 84.5，按论文影响力分数也是第一四分位。
The citation base was 4,295 for 134 articles in 2025. Gold open access takes 21.55 percent of the content, and the rest sits behind a subscription.2025 年的引用基数是 4,295 次，对应 134 篇论文。金色开放获取占 21.55%，其余在订阅墙后。
The backfile carries most of the weight. Of the 2,610 records the publisher deposits, 2,248 are backfile and 362 are current.存量的分量更重。出版方向 Crossref 交存的 2,610 条记录里，2,248 条属存量，362 条属当期。
The journal sits inside a family. The institute runs seven others, from applied mathematics and control theory to mathematical medicine and management mathematics.刊物处在一个家族里。学会另外还办七种，从应用数学、控制理论一直排到数学医学与管理数学。
Advance access has changed how the volume looks. A paper can be read and cited for months before it is given the volume and issue it will finally carry.提前在线改变了卷的样子。一篇论文可以先被读到、被引用好几个月，之后才拿到它最终的卷号与期号。
Nothing in the record suggests a restart or a renaming. The masthead line has held for forty-five years, with the issue count and the volume count never out of step.记录里看不出重起或改名的痕迹。这条刊头线拉了四十五年，期数与卷数从没脱过节。
Editors
Four editors carry the title. Endre Süli is at the University of Oxford, Arieh Iserles at the University of Cambridge, Charlie Elliott at the University of Warwick, and Alexandre Ern at CERMICS, École des Ponts.主编共有四位。Endre Süli 在牛津大学，Arieh Iserles 在剑桥大学，Charlie Elliott 在沃里克大学，Alexandre Ern 在巴黎桥路学校的 CERMICS。
The list is short for the load. Four editors handle about 134 articles a year, which means each of them signs off on roughly one paper a week.相对工作量来说这支队伍很短。四位主编一年处理约 134 篇论文，摊下来每人每周签一篇。
All four hold university posts. None of the four is paid by the journal, and the editorial work sits on top of teaching and research.四位都在大学任职。刊物不给任何一位发薪，编辑的活儿压在教学与研究之上。
The board is the second tier. The journal page routes to the full editorial board through the publisher, and the board link is where subject-level decisions are spread out.编委会是第二层。刊物页面把完整编委名单指到出版方那一侧，按主题分派的判断就在那张名单上摊开。
The institute supervises its own portfolio. A journals board of management inside the IMA oversees all eight titles, which puts the numerical analysis journal under the same governance as the management one.学会自己管这一摊。会内设有一个期刊管理委员会，八种刊全归它看，数值分析这一种与管理数学那一种同属一套治理。
Numerical analysis is the institute's oldest territory. The Leslie Fox Prize for Numerical Analysis is awarded by the same body, and the prize and the journal draw on one community.数值分析是这家学会最老的地盘之一。Leslie Fox 数值分析奖也由同一个机构颁，奖项与刊物吃的是同一群人的饭。
Review practice is not printed on the society page. What is printed is the scope and the four names, and a reader who wants the referee model has to go to the publisher.评审制度没有印在学会页面上。印出来的是范围与四个名字，想知道审稿模式的人得去出版方那边查。
Editorial correspondence runs through the IMA office in Southend-on-Sea. Production, typesetting and the online platform belong to the publisher, and the split has held since 1981.编辑通信走学会在滨海绍森德的办公室。排版、生产与在线平台归出版方，这个分工从 1981 年维持到现在。
Four editors covering one field means specialisms overlap by necessity. A paper on stochastic splitting and a paper on spline end conditions can reach the same desk.四位主编盖一整个领域，专长必然交叠。讲随机分裂的稿子与讲样条端点条件的稿子可能落到同一张桌子上。
The journal also takes the occasional survey, and surveys are commissioned through the editorial side rather than submitted cold.综述是偶发的，走的是编辑侧的约稿而不是冷投。
The masthead has stayed small on purpose. There is no deputy tier and no section editor list, so the four names on the society page are the whole of the visible hierarchy.刊头小是有意的。没有副主编一层，也没有分栏编辑名单，学会页面上那四个名字就是看得见的全部层级。
