铸轧区内铝液与铸轧辊接触瞬间，当铸轧辊冷却强度不足以使整个断面铝液同时产生较大的过冷，而仅能保持胞状晶生长所需的液体温度梯度时，铸轧板就会出现粗大晶粒；根据传热学原理，分析了具体生产条件，提出增大铸轧辊冷却强度、降低前箱温度以及添加铝钛硼丝等防止铸轧板产生粗大晶粒的措施。

A statistics in world range indicates that the Sr/Eu ratios in the peraluminous granites show similar variation trend to those in pegmatitic apatites. This paper suggests that the high Sr/Eu ratio (＞300) in apatites or peraluminous granites is due to the strong partition of Eu〓 into the aqueous fluid, and this ratio can be used as an excellent geochemical indicator of fluid exsolution from magmatic melts.

对世界范围内的过铝质花岗岩统计表明，过铝质岩浆岩的全岩样品中的Sr/Eu也呈现二歧变化，由此本文提出Sr/Eu比值是指示过铝质岩浆体系中岩浆流体相出溶的有效地球化学参数，大于300的Sr/Eu比值是Eu〓强烈分配进入流体相的地球化学标志。
