中文摘要：

由监视相应于方面比率(AR ) 和体积的动态信息的光吸收光谱的时间进化，我们成功了跟随金 nanorods 的生长动力学。结果显示杆生长由二个阶段组成：种子随快 AR 增加发展成杆，杆与经常的 AR 变得大。这里，一个费用转移模型，从维生素酸由电子从 Au (I) 包含正电荷转移到种子和中立化，被介绍了解释杆生长的自动催化作用机制。在数字模拟之间的好协议基于这个模型和试验性的结果支持建议机制。

英文摘要：

By monitoring the time evolution of the optical absorption spectrum corresponding to dy- namic information of aspect ratio （AR） and volume, we succeeded in following the growth kinetics of gold nanorods. The results indicate that the rods growth consists of two stages： seeds develop into rods with a fast AR increase and the rods grow big with constant AR. Here, a charge transfer model, involving positive charge transfer from Au（I） to seed and neu- tralization by electron from ascorbic acid, has been introduced to explain the autoeatalysis mechanism of rod growth. The good agreement between the numerical simulation based on this moldel and experimental results supports the proposed mechanism.
