浅析杂宝纹在明代彩瓷中的应用
０３１浅析杂宝纹在明代彩瓷中的应用摘要：杂宝纹是我国传统的装饰题材，其在宋代末期就已经出现；元时，多用于青花器的辅纹装饰，常以八大码的形式出现；而到了明代，除了继续沿用青花器八大码的表现形式，也逐渐发展出新的装饰形式；同时，明代彩瓷的出现和繁荣，打破了青花器成主流的单一局面，杂宝纹也不可避免的应用在明代五彩斑斓的彩瓷装饰当中；本文基于一些具有代表性的彩瓷，谈谈杂宝纹在明代彩瓷中的应用，并对其装饰形式和艺术语言进行分析。
关键词：杂宝纹；明代；彩瓷 中图分类号：Ｊ５２７ 文献标识码：Ａ 文章编号：１０００—９８９２（２０２３）０２—０３１—（０３）Ａｎａｌｙｓｉｓ ｏｎ ｔｈｅ Ａｐｐｌｉｃａｔｉｏｎ ｏｆ Ｍｉｓｃｅｌｌａｎｅｏｕｓ Ｔｒｅａｓｕｒｅ Ｐａｔｔｅｒｎｓ ｏｆ Ｄｅｃｏｒａｔｉｖｅ Ｐｏｒｃｅｌａｉｎ ｉｎ ｔｈｅ Ｍｉｎｇ Ｄｙｎａｓｔｙ ０前言 杂宝纹是我国传统陶瓷装饰中常见的一种装饰题材，可以直接理解为“多种宝物”，其在陶瓷装饰中的体现主要包含“八吉祥”和其他各种吉祥纹样。
八吉祥纹的组成元素为固定的八种佛教法器，带有着一定的宗教色彩，一般将任意运用超过两组宝物以上的纹饰都可以称为杂宝纹。
它们在陶瓷装饰应用以及演变的长河，逐渐摆脱其自然固有的政治或者宗教色彩，既独立运用，又产生穿插结合。
回望我国陶瓷的发展历程，在经历了宋元黄金时期之后，至明代，达到了又一个高峰，有了宋元陶瓷装饰进入“画花”阶段的基础，陶瓷装饰在明代有了更大的发展，出现了新的彩绘工艺，打破了青花占主流的单一局面，杂宝纹除了继续在青花上得以沿用，其在其他陶瓷彩绘工艺上也有所表现，并且其发展呈现十分繁荣的局面。
１明代彩瓷的主要品种 明代是我国陶瓷装饰工艺发展变革的重要时期之一。
在此之前，我国陶瓷的装饰大多是以施釉为主的素瓷，即便早在宋代，磁州窑就已经开始运用黑白对比的画花装饰手法进行瓷器坯体的装饰，以及在元代，青花瓷上种种精致的青白色的彩绘装饰，它们虽然都属于彩绘瓷的一种，但它们两者关于陶瓷装饰的表现仍然都属于素色的装饰。

For example, Internet Explorer says “Save target as”.From the TransPort web interface, navigate to Administration - Execute a commandEnter the following command:type debug.txtClick the ‘Execute’ button.Wait a few seconds for the data to populate below.Look for “[ENDCFG]” and then “OK” at the very bottom to confirm that no data is missing.Copy and paste the data in a text editor such as Microsoft Notepad.NOTE:The debug.txt file is quite large, so it may be necessary to increase the scroll back buffer in telnet to make it large enough to capture the full file.Do this as follows:Click on the C:\ icon and select “Properties”.Next click “Layout” and set the Screen Buffer Size Height to its maximum.C lick “OK”.Next, Telnet to the TransPort’s IP address.Enter the username and password when prompted.Once connected, issue the following command:type debug.txtThis is a small excerpt from the output, which will be a large file.To copy the file, right-click on the page and select “Mark” from the drop-down menu then starting at the bottom of the page highlight the text and hit “enter”.Paste the data in a text editor such as Microsoft Notepad.PuTTY.exe is a free terminal emulator that can be used to Telnet or SSH to a TransPort to obtain the debug.txt file.Setup PuTTY to log “all session output”and specify a location (“c:\” for example) to save the log file:Input the IP address of the TransPort, select either Telnet or SSH, and then click “Open”:Type “type debug.txt” then hit Enter:The “[ENDCFG]” and “OK” entries confirm that no data is missing:PuTTY may now be closed. The resulting putty.log file should contain the debug.txt output.。
湛博特（Z-Bot）力量抽取杆（Power Draw Bar）说明书
The premier source of tooling, parts, and accessories for bench top machinists. The Z-Bot Power Draw BarThe Z-bot Power Draw Bar for mini mills is designed to work with the popular Tormach tooling system. This system employs an R8 or MT3 collet which remains in the spindle and accepts a ¾” straight shank undercut tool holder. It is designed for a high degree of repeatability and is particularly suited to CNC milling. However, it can also be used as a manual quick change tool system to great effect. The Tormach system is further enhanced by the use of a power draw bar which minimizes tool change time and effort. Driven by a shop compressor, and installed in less than an hour, the Z-bot Power Draw Bar brings a new level of convenience to milling and tool changing. Although a manual system, the Z-Bot Draw Bar can be easily upgraded to serve as a computer controlled component of the Z-Bot Automatic Tool Changing System for Tormach tooling by replacing the manual air valve with automatic solenoid controls.For more information on the Tormach Tooling System, visit /TormachZ-bot Power Draw Bar incorporates a stack of Belleville spring washers that preload the drawbar into the tightened position. The force of the Belleville spring washers draws the collet into the spindle and retains the tool holder.To release the tool holder, air from the compressor is directed through a four way valve to a double acting air cylinder. When the control handle is pushed downward, the air cylinder pushes the piston rod down, thereby moving the lever arm so that it bears on the top of the drawbar. Thelever action multiplies the force of the air cylinder to provide more than 1000 lbs of force to overcome the action of the Belleville spring washers. This action releases the Tormach tool holder. Conversely, when the control handle is moved up, the piston rod is pulled up, which allows the lever arm to clear the top of the drawbar, and the Belleville spring washers pull the tool holder tightly against the spindle.The height of the mechanism is adjusted so that the lever arm clears the top of the drawbar which allows free rotation of the spindle when milling.A silencer/flow control is installed on the “up” air valve exhaust port to assure the air cylinder does not return too violently. It is adjusted and thread locked at the factory. The “down” exhaust port has a simple air muffler as the Belleville washers slow its descent. Do not remove these air controls as it will result in shortened life of the air cylinder.Z-Bot Power Draw Bar ComponentsThe following components are included with the Z-Bot Power Draw Bar:•Power draw bar actuator mechanism •Sheet metal cover•Two stand-offs •Two ¼-20x.25 thumb screws •Four ¼-20x.5 hex bolts•Two M5 x25mm machine screwsYou must also purchase either an MT3 or R8 Z-Bot spring bar set.

关键词：竞赛管理系统；PyCharm；Django；MySQLDesign and implementation of competitionmanagement systemAbstractWith the reform of the national education system, competitions are being held more and more frequently, and the number of students registering for competition is also increasing. Faced with the input of information from so many participants, the way of manually collecting information can no longer meet the current needs. The management of the competition information is another tedious task. The information of the contestants is very large, and errors are usually not allowed. If you perform manual operations, you must manually fill out a large number of forms, which will make the game management work more difficult.The competition management system described in this paper is implemented in the PyCharm environment using the Django framework and MySQL database in python.It has the characteristics of fast retrieval, convenient search, high reliability and large storage capacity. The system is divided into two parts: front-end and back-end. The front-end uses the bootstrap framework. The main functions are user registration, login, browsing events, searching events, browsing statistics of various events, registration, review scoring, ranking, etc. The main realization is the management of user information, event information, ranking information.Keywords: Competition Management System; PyCharm;Django;MySQL目录1 绪论 (3)1.1本设计的目的及意义 (3)1.2本设计在国内的发展概况及存在的问题 (3)1.3本设计应解决的主要问题 (3)2 需求分析 (4)2.1可行性需求分析 (4)2.1.1社会可行性 (4)2.1.2经济可行性 (4)2.2非功能性需求分析 (4)2.3功能性需求分析 (4)2.3.1竞赛信息管理功能 (4)2.3.2用户信息管理功能 (5)2.3.3参赛选手信息管理功能 (5)3运行环境 (5)3.1硬件环境 (5)3.2软件环境 (5)4开发技术及开发工具 (5)4.1开发技术介绍 (5)4.1.1B/S结构及其优势 (5)4.1.2web开发框架—django (6)4.1.3MTV设计模式 (7)4.2开发工具介绍 (7)4.2.1JetBrains PyCharm 2018.3.5 x64 (7)4.2.2MySQL5.7 (8)4.2.3Navicat 12 for MySQL (8)5系统概要设计 (8)5.1系统功能结构设计 (8)5.2数据库连接 (9)5.3数据库E-R图 (9)5.4数据表详细设计 (10)6系统详细设计 (12)6.1注册功能模块 (12)6.2登录功能模块 (13)6.3忘记密码功能模块 (15)6.4 浏览赛事统计并显示 (15)6.5导航条 (16)6.6赛事信息 (17)6.7赛事详细信息 (19)6.8 查询功能模块 (20)6.9 报名功能模块 (21)6.2.10名人堂模块 (21)6.2.11个人中心模块 (23)6.2.12后台管理模块 (23)7系统测试 (24)7.1测试目的 (24)7.2功能测试 (24)8结论 (28)参考文献 (28)1 绪论1.1本设计的目的及意义本设计来源于举办方对竞赛管理系统的实际需要，如果实行手工操作，在参赛人数太多时往往容易出错，但是竞赛项目是要保持公正严谨，不容许有丝毫错误发生。

通用论坛正文提取
摘要：
在如今的大数据时代，伴随着互联网和移动互联网的高速发展，在线产生的数据总量不断攀升，其所蕴含的大量信息已成为各行各业的一个重要的数据分析来源。
其中论坛类网页数量和涉及的信息越来越多，充分挖掘这类信息对社会舆论和情感分析、企业决策和政策制定等具有重要的现实意义。
而各论坛网页风格不一，如何从海量的差异论坛网页中提取有价值的信息是目前互联网数据处理一个急需解决的问题。
本次数据挖掘目标旨在根据论坛网页的特性，提出一种全新的通用论坛正文提取方法。
整个过程主要分为5个步骤：
第一步：数据的清洗。
附件中有些url存在错误，体现为三类：网页找不到、本帖被删除了以及404的错误码，针对这些网页不做正文提取的处理。
第二步：无用标签的清洗。
html网页存在部分非正文的区域，它们大多都是一些js脚本、css样式以及html注释信息，这些标签里面的内容没有价值，事先清除这些标签可以缩小正文区域的搜索范围。
第三步：关键词定位和噪声过滤。
关键词指的是时间文本。
首先利用BeautifulSoup工具查找出满足时间格式的文本，并将这些时间文本划分为目标时间和正文时间。
正文时间出现在主题帖或回复帖的正文内容中，不能帮助定位目标区域，因此将其视为噪声，做相应的过滤处理。
将过滤后的时间文本作为目标时间，生成关键词向量。
第四步：目标内容区域定位。
首先，以DOM树解析各个论坛网页，分析DOM解析树中包含关键词的节点的路径特征，寻找各路径特征的最大公共子序列，定位所有关键词节点的最近公共父亲节点。
其次，在下递归寻找目标区域，有且仅包含一个时间关键词的为目标区域，不包含时间关键词的为非目标区域。
第五步：目标内容提取。
目标内容包括作者，主题、正文和发表时间。
发表时间选取上述的关键词；主题信息通过定位<title>标签并删除相应的网站信息提取得到；针对作者和正文信息，首先划分链接文本和非链接文本，并以结构化的文本特征向量表示。
其次，在链接文本集合中，基于文本结构相似性提取作者信息；在非链接文本集合中，结合文本结构相似性和正文片段空间分布的连续性以及文本密度定位正文信息。
为了验证上述算法的鲁棒性和通用性，我们设计了三个实验，分别是：对比只含主题帖和同时包含主题帖和回复帖的网页内容提取效果；对比同类网页的内容提取效果；对比不同类型网页的内容提取效果。
实验结果表明，上述算法简单高效，内容提取准确率高，且具有很好的通用性。

Text extraction of general BBS
Abstract:
In the current period of big data, with the high-speed development of internet and mobile internet, the amount of data generated online has increased dramatically, which contained a great deal of information that has become an important data resource of most industries. The number of BBS and data rise rapidly, fully excavate this kind of information has important practical significance for public opinion and sentiment analysis, enterprise decision-making and policy-making. However, the style of BBS pages are differ, how to extract valuable information from amounts different BBS web pages is an urgent problem of the Internet data analysis.
The goal of data mining is to propose a new and general method of content extraction in BBS according to the characteristics of BBS. The whole process involved five steps: First step: data clean. There are some wrong urls in the given data, such as “can’t find the webpage”, “The webpage has been delete” or “404 error”. We do not deal with the data with these replies.
Second step: useless tags clean. HTML can be divided into object and none-object regions, non-object regions may belong to js script, css style or comment item in which the content is worthless. Thus, we delete these items in advance in order to reduce the search scope of object region.
Third step: keywords location and noise filtering. Time is considered as the keyword. We firstly find out all text meeting the time format based on BeautifulSoup, and the time is divided into two part of object time and noise time. The noise time generally exit in main text that can't help to locate object region, which should be filtered. After noise filtering, the remaining time is regard as the keyword and generate the keyword vector.
Fourth step: object region location. Firstly, use DOM tree parse every BBS website, analyze path characteristics of the tree nodes contained keyword in the DOM tree, look for the biggest public subsequence of path characteristics and locate the nearest public father node of all keywords. Secondly, search target areas in the recursive way. The area that contains a keyword is the target area, and the area that do not include the time keyword is not the object region.
Fifth step, objective content extraction. Object content includes author, title, text and publish time. The publish time choose above keyword vector. We get the title information by positioning。
