布氏硬度（数）; 缩写词为B.h.n.或BHN（o）
双语例句
- The increase in the content of particles, pressure and cooling rate, all of which had the same influence on decreasing average grain size of remelted materials, improving the compressive strength and Brinell hardness number.
颗粒含量的增加、压力的增大及冷却速率的提高均使重熔后的复合材料晶粒细化，因而使材料抗压强度和布氏硬度得到明显的改善。
