The critical path of the activity networks is figured out with the concept of predecessor matrix. 本文提出的前件矩阵的概念能有效地求解活动网络的关键路径。
One the basis of predecessor's count method of bifidobacterium and considering the anaerobic character of it, the bi-layer matrix flat count method was invented. 在总结前人关于双岐杆菌计数方法的基础上,考虑到双岐杆菌严格厌氧的特点,发明使用了双层培养基平板计数法。
The results showed that the cemented carbide predecessor matrix with different carbon deficient all gets homogeneous microstructure with WC+ Co+ η phases; 结果表明,对于不同贫碳量的基体,其组织结构都呈均匀分布的WC+Co+η的三相组织;
