Thus it is very important to investigate the behavior of oxygen and oxygen precipitation in heavily boron-doping Czochralski silicon (CZSi).
因此研究重掺硼硅单晶中氧和氧沉淀行为具有非常重要的意义，是目前硅材料界研究的热点之一。

The boron-doping technology and metallurgical micro-structure of die steel are discussed from the angle of its resistance to repeated shock compression.
结果指出：模具钢渗硼层在多次冲击压缩载荷下发生一定的塑性变形。
