At present most of the domestic large casting production features a higher investment and lower efficiency.
当前国内的大型铸造自动化生产线，投入高，效率低下。
The main task of the system is to assess assembled vats, pressure vessels and rotation components by using COD and J-integral theory, and to assess large casting and forging components by FATT theory.
它的主要任务是对组合气缸、压力容器、旋转构件进行COD理论和J积分理论的评定，以及对大型铸锻构件进行断口形貌转变温度FATT的评定。
