摘　　要：对TiAl合金常规凝固条件下微观组织形成过程进行了模拟研究,建立了相应的宏观传热、等轴枝晶形核生长二维数学模型,采用一种改进的CA方法与有限差分法耦合进行凝固过程数值计算。结果表明,初生茁相形态与实验结果符合较好。在散热小的中心区域,一次枝晶容易长成纺锤形。The function of automatic switching-on of motorcycle lighting has been overall required in corresponding Europe regulations. The lighting installation standards of China are formulated referencing to the corresponding Europe regulations. The requirements of automatic switching-on of motorcycle lighting are different between Chinese standards and Europe regulations. This article will compare and analyze the difference and give corresponding suggestions.
