而论文的排版一直在困扰着我们，word排版显得过于复杂，所以建议使用latex。
LaTeX（/ˈlɑːtɛx/，常被读作/ˈlɑːtɛk/或/ˈleɪtɛk/），排版时通常使用LATEX，是一种基于TeX的排版系统，由美国计算机科学家莱斯利·兰伯特在20世纪80年代初期开发，利用这种格式系统的处理，即使用户没有排版和程序设计的知识也可以充分发挥由TeX所提供的强大功能，不必一一亲自去设计或校对，能在几天，甚至几小时内生成很多具有书籍质量的印刷品。
对于生成复杂表格和数学公式，这一点表现得尤为突出。
因此它非常适用于生成高印刷质量的科技和数学、物理文档。
这个系统同样适用于生成从简单的信件到完整书籍的所有其他种类的文档。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
