die breakthrough

Taken the hot-forming punch of a glass part as an example,the main defects of hot- forming punch is explained,including punch crack and punch wound.

以玻璃制件的热成形凸模为例,说明热成形凸模的主要缺陷:凸模裂纹和凸模伤。

Based on the quantum molecular dynamics(QMD),statistical decay model(SDM)and the semi empirical multi mode fission model,the mass yield distributions of proton induced fission near 200MeV were calculated.

采用量子分子动力学 (QMD)、统计衰变模型 (SDM)和半经验的多模裂变模型方法计算了能量在 2 0 0MeV附近的中能质子入射重核引起裂变的裂变产物质量分布 ,得到了与实验相符合的结果 ;同时对锕系核素和非锕系重核素分别给出了一组合理的多模裂变模型参
