什么说话口气，您比google还牛呀.

炭素铅笔 : 学美术的人sketch用的
有没有carbon pencil 您古狗一下呀
The carbon pencil is the perfect combination of charcoal and graphite. It has a fine grain, and goes on smoothly and precisely in rich, velvety, matte black lines. Carbon pencils have a consistent softness, for superior blending and texture.

普通铅笔 is made of graphite and wood only.
