In chapter two, the basic principle of RLA technique is presented, including the characteristics of laser induced plasma and the principle of resonant laser ionization. 第二章阐述了共振激光烧蚀技术的基本原理,包括激光等离子体的特性和共振激光电离的基本原理;
Based on reaction limited aggregation model, we have investigated the dynamical process of film epitaxial growth in the presence of surfactant. 根据反应限制聚集(ReactionLimitedAggregation,RLA)模型,研究表面活性剂存在时的薄膜外延生长动力学过程。
Results The time for performing operation through RPA and RLA was shorter than that through TAA ( P < 0 01) Blood transfusion during operation through RLA and RPA was less than that through TAA. 结果通过RPA及RLA途径完成手术,时间短于TAA(P<001)。
