自己封装的鼠标封装的鼠标场景漫游工具类RoamingScenceManager,跟界面没有任何关系,压缩包里面有三个工程,分别是Qt,Win32(原生OpenGL界面),MFC三个环境,里面都用到了RoamingScenceManager,用法简单,适合刚刚学opengl的新手构建场景。

完整英文版IEC62660-3:2016Secondarylithium-ioncellsforthepropulsionofelectricroadvehicles-Part3:Safetyrequirements(电动道路车辆推进用二次锂离子电池第3部分:安全要求),IEC62660-3:2016规定了用于电动汽车(EV)包括电池电动汽车(BEV)和混合电动汽车(HEV)推进的二次锂离子电池和电池组的安全性能的测试程序和验收标准。
本国际标准旨在确定在电动汽车正常运行过程中预期使用的电池组和系统中所用电池的基本安全性能,以及合理可预见的误用或事故。
本标准中电池的安全要求是基于这样的前提,即电池必须在电池制造商规定的电压,电流和温度限制(电池工作区域)内正确用于电池组和系统中。
本标准不包括电池在运输和储存过程中的安全性评估。

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。
