摘 要
随着我国国力的增强和计算机技术的不断发展和进步,个人计算机早已走入了
寻常百姓家,上到几十岁的中老年人,下到十几岁的学生朋友都会操作计算机,人
们的很多生活习惯与消费习惯都随之发生了改变,计算机技术为人们的生活带来了
很多的便利。数学是一门非常重要的学科,可以开发学生的思维,增强学生的综合
素质,所以从小学到大学的各大教学阶段都安排了数学的课程,在传统的数学课堂
中,存在许多的限制和弊端,比如老师的教学方法过于单一,都是以老师本身为主
体,理论知识的讲解会贯穿整个一节课的 45 分钟,会导致学生无法完全集中注意
力,也无法充分发挥学生们的主动学习的积极性,这也会难以避免的导致学生无法
接收到良好的学习效果。而现在通过科学的教学方法和发达的计算机硬件设备和软
件系统,学生们的信数学课堂早已发生了翻天覆地地的改变,真正的做到了以学生
为主体,学生除了可以在课堂上认真听老师讲课进行学习之外,还可以利用各种数
学学习软件进行学习,而本文就是对网络环境下数学公式绘制软件的设计与实现过
程。
本系统使用的是 C/S 架构,整个系统都在客户端程序中完成,使用 Python 窗体
进行布局,这样可以使整个前台页面变得更美观,极大的提高了用户的体验。后端
的代码技术选择的是 PYTHON,PYTHON 语言是当下最常用的编程语言之一,可以保证
系统的稳定性和流畅性,PYTHON 可以灵活的与数据库进行连接。本系统的数据使用
的 MYSQL 数据库,它可以提高查询的速度,增强系统数据存储的稳定性和安全性。

Abstract
With the enhancement of China's national strength and the continuous
development and progress of computer technology, personal computers have
already entered the homes of ordinary people. From the age of tens to the elderly,
to the age of teenagers, students and friends can operate computers. Many of
people's living habits and consumption habits have changed with it, and computer
technology has brought a lot of convenience to people's lives. Mathematics is a very
important discipline that can develop students' thinking and enhance their
comprehensive quality. Therefore, mathematics courses are arranged at various
teaching stages from primary school to university. In traditional mathematics
classrooms, there are many limitations and drawbacks, such as the teacher's
teaching methods are too single, and they are mainly based on the teacher himself.
The explanation of theoretical knowledge will run through the entire 45 minutes of a
class, It can lead to students not being able to fully concentrate and give full play to
their initiative in learning, which can also inevitably lead to students not receiving
good learning outcomes. Now, through scientific teaching methods and developed
computer hardware equipment and software systems, students' information and
mathematics classrooms have already undergone tremendous changes, truly
achieving a student-centered approach. In addition to carefully listening to the
teacher's lectures in the classroom for learning, students can also use various
mathematical learning software for learning, This article is about the design and
implementation of mathematical formula rendering software under the network
environment.
This system uses a C/S architecture, and the entire system is completed in a
client program. Python forms are used for layout, which can make the entire
foreground page more beautiful and greatly improve the user experience. The back-
end code technology is PYTHON, which is one of the most commonly used
programming languages at present, ensuring the stability and smoothness of the
system. PYTHON can flexibly connect to databases. The data in this system uses a
MYSQL database, which can improve the speed of queries and enhance the stability
and security of system data storage.
Key words: Mathematical functions; Draw; PYTHON; MySQL

1 绪论
1.1 课题研究背景
计算机技术对当今社会发展和人们生活水平的提高是很重要的组成部分,
人们可以通过网络从衣食住行等方面提高自己的生活质量,比如不想做饭的时
候可以通过外卖平台下单点餐;想买新衣服但又不想出门的时候可以通过淘宝
网等购物网站进行衣服的挑选;想要出行可以提前通过携程网或途游旅行等应
用进行机票或酒店的预购……通过网络进行线上的操作可以避免很多时间的浪
费。
以往学生学习数学函数的方式并不是特别科学,主要存在着两个弊端。数
学课堂中传统教学方法的第一个弊端就是教师的教学方法过于单一。老师们没
有摆脱传统教学方法的束缚,大都采取整节课讲述理论知识这种方式,这种教
学方式也许在其他的科目中没有问题,但在数学的课程中是有一定弊端的。首
先一节课有 45 分钟,而通过科学的调查,学生们很难整堂课集中自己的注意
力,所以哪怕老师们辛苦的进行了 45 分钟的授课,也无法保证学生们的听课效
果对得起老师们的付出。传统的教学方法都是以老师为主体,老师讲,学生
听,但随着教学方法和观念的创新,这种单一的教学方法逐渐被淘汰了。第二
个弊端是学生的学习方法并不科学。对于一些偏记忆的科目比如语文、或英语
等,学生们或许可以通过死记硬背的方式进行学习,哪怕没有完全的理解知识
点也可以依葫芦画瓢的完成课堂的任务,但这样极易让学生形成思维定式,认
为学习就是应该这样的,这会导致学生们的学习效率变的很差。对于数学这门
课程,学生们需要更加科学的学习方法。
