The popular YouTube channel Quint BUILDs originally made in-depth engineering videos on something called GD&T. It's a standard published by ASME (American Society of Mechanical Engineers) used...

Geometric Dimensioning and Tolerancing (GD&T) is an engineering standard governing mechanical fits of parts. Quint is one of 5 people in his home state of Oregon and about 500 individuals worldwide to hold a senior level certification in this standard (ASME Y14.5).

Topics like bonus tolerance and zero position tolerance are covered in-depth to help you better understand the fundamentals of GD&T. The exercises are all in inch units but are easily applied to metric applications.

2019年10月22日 · 在386平台各种保护措施中最重要的就是全局描述符表 (GDT)。GDT为内存的某些部分定义了基本的访问权限。我们可以使用GDT中的一个索引来生成段冲突异常, 让内核终止执行异常的进程。现代操作系统大多使用"分页"的内存模式来实现该功能, 它更具通用性和灵活性。 GDT还定义了内存中的的某个部分是可执行程序还是实际的数据。 GDT还可定义任务状态段 (TSS)。TSS一般在基于硬件的多任务处理中使用, 所以我们在此并不做讨论。 需要注意的 …
