A massive oak claims its ground for 200 years or more, outcompeting all other would-be canopy trees by casting a dense shade and drawing up any free water in the soil.
To solve the problems of massive work and low efficiency during Casting Rolling processes design, an expert system for Casting Rolling process design of copper alloy tubes had been developed.
针对铸轧工艺设计工作量大、效率低的问题，进行了“铜合金管材铸轧工艺专家系统”软件的开发。
