For submicron cermet,the grains with white cores,are much more than that in micron cermet,and the properties are higher. 但对于亚微米级的金属陶瓷，其芯部为白色的陶瓷颗粒的数目要比微米级的金属陶瓷多，其断裂韧性略有下降，但其抗弯强度要高出许多。
The machining results show that the developed machine tool can reach the accuracy of micron order. 基于此原理开发的活塞异形销孔设备达到微米级加工精度。
