黑体hēitǐ
1.排版、印刷上指笔画特别粗,撇捺等不尖的字体(区别于‘白体’as compared with ‘lean type’})。{boldface; heavy-faced type in composition and printing, in Chinese meaning thick strokes and the left-falling and right-falling strokes not pointed at the end}
2.对照射在上面的白光能够全部吸收的理想物体。一个中空的不透明物体,表面留一透光小孔,这个小孔就十分近似于黑体的表面。{blackbody; an ideal body that completely absorbs all radiating energy falling upon it, with no reflection. Leaving a small hole on the surface of a hollow opaque object closely approximates to the surface of a blackbody.}也叫also绝对黑体{juéduì hēitǐ}。 |
