WaterQualityAnalysisSimulationProgram(WASP)是在1983年DiToro等人建立模型的基础上的加强版。
优点：灵活性：能够模拟大部分水体类型，河流、湖泊、河口、海洋水体。
内部链接：热模块计算结果提供给富营养化模块，再用于有毒物质模拟。
外部链接：能够和多种模型耦合。
模块灵活性三种处理技术：分为简单、中级和复杂的处理方式。
模拟大部分水质问题：常规污染物，溶解氧、富营养化、温度；
有毒污染物，有机物、简单的金属、汞等局限性：WASP的研究对象为完全混合水体控制单元，比如排污口附近这种类型的问题不能模拟。
非水相：油的比重、粘度和水不一样。
进入水体后，不同于水，WASP不能模拟。
干涸：我们认为水体的容量是一定的，不变的。
有很强的蒸发作用，对水体的容积有一个很显著的变化产生，这种情况WASP也是不适用的。
很多水质模型都存在这种限制。
金属，重金属：很多过程是不能体现的。
WASP(Thewaterqualityanalysissimulationprogram,水质分析模拟程序)是EPA推荐使用的水质模型软件,使用较为广泛,能够模拟河流、湖泊、水库、河口等多种水体的稳态和非稳态的水质过程。

引子：自上世纪末KentBeck提出TDD(Test-DrivenDevelopment)开发理念以来，开发和测试的边界变的越来越模糊，从原本上下游的依赖关系，逐步演变成你中有我、我中有你的互赖关系，甚至很多公司设立了新的QE(QualityEngineer)职位。
和传统的QA(QualityAssurance)不同，QE的主要职责是通过工程化的手段保证项目质量，这些手段包括但不仅限于编写单元测试、集成测试，搭建自动化测试流程，设计性能测试等。
可以说，QE身上兼具了QA的质量意识和开发的工程能力。
我会从开发的角度分三期聊聊QE这个亦测试亦开发的角色所需的基本技能。
前情概要：作为QE三部曲的最后

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。
