基于pgfSweave的漂亮中文动态文档

tex文件的中文算法流程伪代码在撰写科技论文或者技术文档中，算法流程图和伪代码是非常重要的部分。

而在使用LaTeX撰写中文文档时，如何添加中文算法流程图和伪代码是一个值得探讨的问题。

一般来说，我们可以使用algorithm2e宏包来实现中文算法流程伪代码的编写。

具体步骤如下：1.在导言区调用algorithm2e宏包，并设置中文选项。

usepackage[UTF8, heading, scheme=plain]{ctex}usepackage{algorithm2e}2.在正文中，使用algorithm环境来编写算法，并设置中文标题、关键字等信息。

begin{algorithm}[h]tcaption{中文算法流程}tKwIn{输入参数1，输入参数2}tKwOut{输出结果}tBlankLinetWhile{循环条件}{tt执行操作1;tt执行操作2;t}tReturn{返回结果}end{algorithm}其中，KwIn、KwOut和Return分别表示输入、输出和返回操作，While表示循环操作。

3.在伪代码中添加中文注释，即可实现中文算法流程伪代码的编写。

begin{algorithm}[h]tcaption{中文算法伪代码}tKwIn{输入参数1，输入参数2}tKwOut{输出结果}tBlankLinetWhile{循环条件}{tt// 执行操作1tt操作1;tt// 执行操作2tt操作2;t}tReturn{返回结果}end{algorithm}通过以上步骤，我们可以实现中文算法流程伪代码的编写。

需要注意的是，在编写算法时，要注意代码的格式、缩进和注释的位置，以便于阅读和理解。

Hugo博客中⽂指南（基础教程）1. 安装 Hugo从 Hugo 项⽬主页下载 Releases ⽂件，解压hugo.exe⽂件到C:\Windows\System32⽬录下。

2. 创建站点hugo new site mysite新的站点⽂件夹 mysite 就⾃动⽣成到了当前⽬录下：在执⾏完hugo new site命令后你会得到⼀个包含以下⽂件的⽬录。

.├── archetypes/├── config.toml├── content/ # 储存⽹站的所有⽂章内容├── data/├── layouts/ # 全局样式，优先级⾼于主题下的 layouts ⽂件夹├── static/ # 静态⽂件，优先级⾼于主题下的 static ⽂件夹└── themes/ # 主题⽬录3. 新建页⾯和⽂章新建⼀个 about 页⾯：hugo new about.mdabout.md ⾃动⽣成到了 content/about.md，内容如下：---title: "About"date: 2020-04-07T22:05:28+08:00draft: true---创建第⼀篇⽂章，放到 post ⽬录：hugo new post/myfirst.mdmyfirst.md ⾃动⽣成到了 content/post/myfirst.md，内容如下：---title: "Myfirst"date: 2020-04-07T22:05:28+08:00draft: true---其中 draft: true 表⽰为草稿⽂件，正式发布前需将值修改为 false，或者直接删除 draft 整个参数，否则正式发布时不会⽣成⽂章。

4. 安装主题到或从 Github 下载⼀款主题，解压到 theme ⽬录下：通过命令⾏的⽅式使⽤主题：hugo -t 主题⽬录名通过在 config.toml 配置使⽤：theme = "主题⽬录名"5. 编译输出（构建 Hugo ⽹站）在 Hugo ⽹站⽂件夹的根⽬录下，执⾏hugo命令来构建。

/fx125437@126/blog/static/11357041201110279126622/?latestBlogFlunet中的动网格设置不仅包含网格的更新方法，主要包括smoothing；layering;remeshing 三种方法，同时也需要设置相关的边界和流体区域的运动类型（Stationary Zones；Rigid Body Motion；Deforming Motion ；User-Defined Motion ）以及对于刚体运动所需要的运动方式的定义。

对于相关运动方式的定义fluent提供了两种方式来定义其运动轨迹（UDF&Profile），下面分别介绍：ProfileUDFFluent定义的三个宏来编写相关的动网格UDF先介绍DEFINE_CG_MOTION宏1、描述通过使用DEFINE_CG_MOTION宏来指定特定动态区域的运动。

该宏能够指定每一时间步的线速度与角速度。

ANSYS FLUENT利用这些速度更新动态区域的节点位置。

该宏只能用于编译型。

2、语法说明DEFINE_CG_MOTION(name,dt,vel,omega,time,dtime)（1）name:宏名，由用户指定，需要符合UDF中宏命名规范。

（2）dt：类型为Dynamic_Thread *dt，是一个包含了用户指定的动网格属性结构的指针。

（3）vel：数据类型为real vel[]，速度向量，vel[0]表示x方向线速度，vel[1]表示y方向，vel[2]为Z方向。

（4）omega：real omega[]，角速度向量。

索引为0~2，分别表示x,y,z方向角速度。

（5）time：类型为real，表示当前时间。

（6）dtime：类型为real，表示时间步该宏的返回类型为void此宏包含有六个参数，其中name是用户提供，其他的参数如dt,vel,omega,time,dtime均有ansys fluent求解器传递。

1、关于万维网，以下说法正确的是万维网是一种建立在Internet上的信息检索系统；万维网主要以“超文本”或“超媒体”形式提供信息；万维网即因特网；2、WWW是World Wide Web的简称，在浏览网页时遵循的是HTTP协议。

3、以下HTML标记，<br>是非封闭型的。

4、若要求对文档中部分内容在浏览时几乎不做修改地输出，可以用<pre>标记通知浏览器。

5、创建最小的标题的文本标签是<h6></h6>6、对于一个文字超链接，可以设置link、alink、vlink状态的颜色标记。

7、Internet Explorer中默认状态下，层的标记为<Div>8、下列meta、base、link标记如果存在必须放于HTML文档的头部。

9、HTML代码<table width=# or %>表示设置表格的宽度：用像素值或百分比形式。

10、以下标记不能通过选择“查看”à“可视化助理”à“不可见元素”使其可见的是框架边框。

11、使用“插入”→“图像”命令，要将图像从目前网站之外的文件夹插入页面中。

则要在“网站定义”对话框中，设置默认图像文件夹选项，那就会自动复制该图像到网站中的pic 文件夹，而不会产生警告信息。

12、Macromedia Dreamweaver MX 2004中，“站点”这个概念既可表示位于Internet服务器上的远程站点，也可以表示位于本地计算机上的本地站点。

这句话是正确13、如果需要使打开的文件自动被取出，则在“定义远程信息”时要选中打开文件之前取出。

14、Dreamweaver MX 2004中一个网页可以在文档窗口中以3种视图方式打开。

15、在Dreamweaver 中,关于“资源”面板的说法错误的是模板和库不在“资源”面板中显示。

16、站点地图所描述的站点结构，是以主页为开始点。

17、Dreamweaver MX 2004中，设置“页面属性”中“下划线样式”属性，不能去除超链接文字中下划线的是“始终有下划线”和“仅是图像变换时隐藏下划线”两项。

transformation,i.e.the transformed values are rounded to the nearest precision.If NA(the default),no rounding is performed and theexact transformed value is returned.DetailsTransformation between eras uses the scale,epoch,direction and unit parameters of the era definition.NA values for any of these parameters in the source or destination era will cause an error.This is most often encountered when either are measured in’radiocarbon years’,which cannot be related to a calendar time scale without calibration or un-calibration.The transformation function is exact and treats years as a real number scale.This means that transformations between eras with different year units(e.g.Gregorian to Julian)and/or epochs not aligned to1January in the Gregorian calendar(mon Era to Islamic calendars)will likely return non-integer values.The precision argument provides a convenient way to round the result if you do not need this level of precision.It is also useful for working around the ambiguous definition of’present’in various geological time-scales.ValueA yr object in the era specified by era.See AlsoOther years with era functions:yr_era(),yr()Examplesx<-yr(10010:10001,"cal

R语言丨diRblo：中文文本分析方便工具包chinese.misc简介（附文本样例）展开全文现在NLP技术那么发达了，各种工具那么NB了，可是用R做文本分析的人居然还得为如何读文件不乱码、如何分词、如何统计词频这样的事犯难，也是醉了。

如果老停留在这个水平上，那各位亲你们离自己整天挂在嘴边儿的大数据机器学习之类的基本上就无缘了。

所以希望大家能把更多精力放到算法上，而不是用在一些琐碎、浪费时间又极其恼人的事情上。

其实像文本清理这种活儿，基本上就应该是用鼠标点吧点吧就能自动完成的，若要还费半天劲的话纯属扯淡。

所以，chinese.misc这个R包就要来完成这个任务。

chinese.misc（目前为0.1.3版本）的功能极其简单，主要用于对中文文本进行数据清理工作，此外还包含另外一些实用的处理和分析功能。

在生成文档-词语矩阵的功能上，可以代替对中文不是太支持的tm包，特别是在减少乱码方面。

如果你现在还忙于看如何分词、如何删去停用词、如何计算词频之类的工作，那么这些都用不着看了，让我们把工作变得更无脑些！这个包的中文手册见https:///githubwwwjjj/chinese.misc。

不过，英文pdf 比中文说明详细多了。

chinese.misc的核心函数是corp_or_dtm，可直接从文件夹名/文件名/文本向量中生成文档-词语矩阵，并且自动或按使用者要求进行一些文本清理工作。

此外，软件包中dir_or_file、scancn、make_stoplist、slim_text 等函数都是在中文文本分析中比较实用的函数，可以帮助使用者减少很多麻烦。

在这里，我只展示一下这个包的少数功能，其它功能还请大家去看中文手册。

文本样例请到/s/1nuXLBg1下载，里边是30篇中纪委巡视报告。

如果你解压后文件数不对或是乱码，那几乎只可能是因为你正在使用MAC。

请尽量在WINDOWS上搞。

我们假设你解压后的文件路径是'f:/sample'。

Aceeditor中⽂⽂档介绍Ace是⼀个⽤JavaScript编写的可嵌⼊代码编辑器。

它与Sublime，Vim和TextMate等本地编辑器的功能和性能相匹配。

它可以轻松地嵌⼊任何⽹页和JavaScript应⽤程序中。

官⽹地址：Github:vue版：快速开始简单使⽤<div id="editor" style="height: 500px; width: 500px">some text</div><script src="src/ace.js" type="text/javascript" charset="utf-8"></script><script>var editor = ace.edit("editor");</script>设置主题和语⾔模式要更改主题，请为编辑器配置要使⽤的主题路径。

主题⽂件将按需加载：editor.setTheme("ace/theme/twilight");默认情况下，编辑器为纯⽂本模式。

但是，所有其他语⾔模式都可以作为单独的模块使⽤。

语⾔模式也将按需加载：editor.session.setMode("ace/mode/javascript");编辑器状态Ace将所有编辑器状态（选择，滚动位置等）保留在editor.session中, 这对于制作可切换式编辑器⾮常有⽤：var EditSession = require("ace/edit_session").EditSessionvar js = new EditSession("some js code")var css = new EditSession(["some", "css", "code here"])// 要将⽂档加载到编辑器中，只需这样调⽤editor.setSession(js)在项⽬中配置Ace// 将代码模式配置到ace选项ace.edit(element, {mode: "ace/mode/javascript",selectionStyle: "text"})// 使⽤setOptions⽅法⼀次设置多个选项editor.setOptions({autoScrollEditorIntoView: true,copyWithEmptySelection: true,});// 单独设置setOptions⽅法editor.setOption("mergeUndoDeltas", "always");// ⼀些选项也直接设置，例如：editor.setTheme(...)// 获取选项设置值editor.getOption("optionName");// 核⼼Ace组件包括（editor, session, renderer, mouseHandler）setOption(optionName, optionValue)setOptions({optionName : optionValue})getOption(optionName)getOptions()设置和获取内容：`editor.setValue("the new text here"); // 或 session.setValueeditor.getValue(); // 或 session.getValue获取选定的⽂本：editor.session.getTextRange(editor.getSelectionRange());在光标处插⼊：editor.insert("Something cool");获取当前光标所在的⾏和列：editor.selection.getCursor();转到某⼀⾏：editor.gotoLine(lineNumber);获取总⾏数：editor.session.getLength();设置默认标签⼤⼩：editor.getSession().setTabSize(4);使⽤软标签：editor.getSession().setUseSoftTabs(true);设置字体⼤⼩：document.getElementById('editor').style.fontSize='12px';切换⾃动换⾏：editor.getSession().setUseWrapMode(true);设置⾏⾼亮显⽰：editor.setHighlightActiveLine(false);设置打印边距可见性：editor.setShowPrintMargin(false);设置编辑器为只读：editor.setReadOnly(true); // false为可编辑窗⼝⾃适应编辑器仅在resize事件触发时时调整⾃⾝⼤⼩。
