Correctional checking formula of melt flow ratio in injection molding was obtained by introducing a correction coefficient β which reflected the complexity degree of mold cavity. The results show that, the maximum flow ratio of 486 can be obtained when injection pressure ranges from 150 MPa to 160 MPa in Archimedes spiral mold for PP, while maximum flow ratio of 419 can be obtained when injection pressure ranges from 160 MPa to 170 MPa for PE. There is a local fluctuation phenomenon for flow ratio and corresponding injection rate in square spiral mold when injection pressure of 100, 120 and 150 MPa for PP and 130, 140 MPa for PE are reached respectively,and this phenomenon is more serious for good fluidity of melt. The average flow ratio in Archimedes spiral mold is 6% larger than that in square spiral mold for PP, and 4% for PE, the average flow ratio of PP is 19% bigger than PE in Archimedes spiral mold, and 15% in square spiral mold. The influence of the cavity profiles on the melt flow ratio is more significant for good fluidity of melt.

研究结果表明：在阿基米德螺旋线模具中，PP在注射压力为150~160 MPa时取得最大流动比485，PE在注射压力为160~170 MPa时取得最大流动比419；在方形螺旋线模具中，PP在注射压力为100，120和150 MPa，PE在注射压力为130和140 MPa时流动比及所对应的注射速率出现波动，且流动性好的熔体波动更为严重；PP在阿基米德螺旋线模具中的流动比均值较其在方形螺旋线模具中大6%，而PE大4%；在阿基米德螺旋线模具中流动比均值PP比PE的流动比均值大19%，而在方形螺旋线模具中PP的流动比均值比PE的大15%；流动性好的熔体受模具型腔轮廓特征影响大。

An important law was first discovered by Archimedes, who was a scientist who died over 2,000 years ago.

阿基米德首先发现了一个重要的定律。阿基米德是一个科学家，死于2000多年前。

Cu6Zr5, the basic cluster of the primary devitrification phase of Cu-based amorphous alloys, is selected as cluster model based the on structure heredity existing between amorphous alloys and primary devitrification phases.

根据非晶与其晶化相存在结构遗传关系，以Cu-Zr基非晶晶化相Cu10Zr7中的Cu6Zr5阿基米德反棱柱为团簇模型，利用离散变分方法从电子层次研究了Al元素对Cu基非晶合金团簇稳定性的影响。

At the same time,Archimedes gives an exact proof on the formula of area of circle,with the method of exhaustion method depending on the Cyclotomic.

刘徽之前，希腊的阿基米德用穷竭法也证明了圆的面积公式。其中，刘徽的证法强调计算的程序性和构造性，而阿基米德则倾向于演绎的严谨性。
