有产品跟美国线规相关，维基上找的线规资料，怕奥运以后又被封，留个底。
看不完整时点上面的“边栏”将右面2栏关掉，就可以看到格式正确的了。
美国线规AWG，又称布朗夏普线规。是在1857年制定的一种线规标准，用于圆形实心非铁的导电电线。

American wire gauge (AWG), also known as the Brown & Sharpe wire gauge,
is a standardized wire gauge system used since 1857 in the United States and
other countries for the diameters of round, solid, nonferrous, electrically conducting wire.

 

Table of AWG wire sizesThe table below shows various data including both the resistance of the various
wire gauges and the allowable current (ampacity) based on plastic insulation.
The diameter information in the table applies to solid wires. Stranded wires are
calculated by calculating the equivalent cross sectional copper area. The table
below assumes DC, or AC frequencies equal to or less than 60 Hz, and does not
take skin effect into account. Turns of wire is on a best-case scenario when winding
tightly packed coils with no insulation.
