The screw die has great superiority in producing wide and thick polymer sheet, so it is significant to study the flow simulation and parameters optimization on the screw die. 但長(cháng)期以來(lái)，國內橡塑生產(chǎn)行業(yè)一直沒(méi)有很理想的寬幅厚板材生產(chǎn)設備，而螺桿分配機頭在生產(chǎn)寬幅厚板材時(shí)有很大的優(yōu)勢，故對螺桿分配機頭進(jìn)行流場(chǎng)模擬與參數優(yōu)化是一項非常有意義的工作。
Basin basement palaeo-heat flow is a basic boundary parameter condition to realize basin geothermal field simulation. 摘要盆地基底古熱流是實(shí)現盆地地熱場(chǎng)模擬的基礎邊界參數條件。
