2020年3月27日 · 那么今天测评我也请来和gdx2同价位的随身听N62+t01卡（7200元），价位区间相同的铠音66组合idac6和iha6。 （8400元，含xlr线材就8900）再就是看作为dac的gdx2去推万元耳放ifi pro ican 又是什么表现。 首先我看中这台是因为一位老烧说高登是中国的惊雷。 后来我一查惊雷的耳放，噢，都是参考级别的。 就去买了一台。 本人从随身到台机，这段时间玩过不少了。 慢慢习惯台机，但说到使用方便，我还是觉得一体机有一些不折腾，不占地方的优势在。 而 …

2 What is GD&T? It is compilation of symbols and rules that effi ciently describe and control dimensioning & tolerancing for all drawings (castings, machined components,etc.). It is documented in ASME Y14.5M which has the symbols, rules, and simple examples. Also ASME Y14.8 has guidance for casting and forging drawings. 3 Why should GD&T be ...

轮廓度被看作是 形位公差 中最有力的控制，用来定义零件大小，位置，方向和形状的组合控制。 根据设计要求，轮廓度可以相对于或不想对于基准。 面轮廓和线轮廓常用来控制平面，圆柱，圆锥，曲面和不规则曲面。 可应用于整个零件、多个要素、单独表面或从零件的各横截面中获取的单独轮廓。 标注轮廓度，既可以有基准，也可以没基准 。 当标注轮廓度有基准时，它是相关特征控制， 当标注轮廓度没有基准时，它是一个形状控制。 轮廓：是零件特征在给定平面内的外部形状 …

Geometric Dimensioning and Tolerancing (GD&T) is a system of symbols and standards used in engineering drawings and models to specify the required form, size, orientation, and location of parts and features. It is an important tool for ensuring the interchangeability, functional accuracy, and reliability of manufactured components.

Geometric dimensioning and tolerancing, often referred to as GD&T, is a symbolic language used on engineering drawings and models to define the allowable deviation of feature geometry.
