蒙面黑布坠落的那一刻，尹旭感觉在这张脸似曾相识。Is IT a low-paid technical job?徐晴看着他，又想着他说的那些故事，直觉得糟化弄人。他颓丧极了：有围墙可不好办，而且这里到处都是人，就算爬墙也容易让人看见。The outer surface is plated with oxygen-free copper, and the raw materials of the core wire are brass, bronze and miscellaneous copper. Because the raw materials of copper inside and outside are different, it is called copper clad copper. The quotation is moderate, and the quotation for miscellaneous copper is usually only half or lower than that for oxygen-free copper. The produced wire is attributed to non-standard wire, and its anti-twisting and anti-oxidation functions are better than those of copper-clad aluminum. Suitable for induction and wiring engineering with low accounting, it can lay hidden lines in the wall. However, due to the influence of raw materials, the resistance is relatively large, with a 100-meter resistance of 25-35 ohms or even more, and the signal attenuation is very large. It is not so-called all-copper. We pay attention to the distinction.
