A better transition layer material was confirmed,which overcame the problem of fragmentation and lamination of PDC.
确定了一种效果较好的过渡层,较好地解决了金刚石/硬质合金复合片碎裂及分层的问题。
The fragmentation influences the char combustion behavior in a fluidized bed combustor.
利用下行气流振动床代替流化床 ,研究了煤的碎裂特性 。
Based on the perturbative QCD predictions of gluonic distributions and branch cross section of the J/(?) decay via hadronic, electromagnetic,and radiative channels, the strict solutions of LUND area law of string fragmentation had-ronization are used to treat nonperturbative hadronic production processes, a possible description and Monte Carlo packet for the J/(?) hadronic decay are obtained.
基于微扰QCD所预言的J/ψ衰变道胶子分布及其分支截面和LUND弦碎裂模型强子化面积定律的严格解,得到J/ψ所有衰变模式的微扰和非微扰过程的一种可能的描述,相应的Monte Carlo产生器LUARLW所作的初步模拟结果与BES获取的J/ψ数据的多种带电粒子谱分布和事例形状拓扑分布符合较好。
