Human capital,as a synthesis of wisdom and physical fitness condensed in workers,is sometimes confused with technological innovation by existing literature.This paper makes comparisons between these two terminologies.Technological innovation is a short-term activity that attaches importance to economic benefits while human capital accumulation is a long-term strategic process with lifelong benefits,and human capital is the foundation of technological innovation.In empirical part,this paper adopts Solow Residual Method to calculate stock,elasticity and growth rate of human capital of 10 countries after eliminating physical capital,labor force and technological innovation.It is found that human capital stock in the United States is the largest and human capital growth in China is the fastest.Calculation is followed by measurement.We construct a comprehensive index of human capital by using Index Weight Assignment Method and Two-level&Three-factor CES Function to measure and predict human capital level in China.Both calculating and measuring results show that growth rate of China’s human capital is around 5%.In the future,for high-quality economic development,China should give priority to human capital development and comprehensively improve human capital competitiveness. 展开更多

H62铜合金应用广泛。分析不同环境因素对H62铜合金腐蚀的影响,对腐蚀防护具有重要意义。设计二因素的全面试验,通过电化学工作站测得H62铜合金在温度、氯离子浓度2个因素3个水平下的极化曲线,利用方差分析评估温度与氯离子浓度对H62铜合金腐蚀的影响。试验说明,随着温度的升高以及氯离子浓度的增大,H62铜合金的腐蚀情况加重。温度与氯离子浓度有交互作用,在氯离子参与的情况下,温度对H62铜合金腐蚀作用增强,氯离子浓度对H62铜合金腐蚀的影响大于温度对H62铜合金腐蚀的影响。 展开更多

针对30CrNiMo(/%:0.30C,0.85Mn,0.25Si,0.015P,0.008S,0.96Cr,0.43Mo,0.78Ni,0.025Al)高强度钢调质棒材冲击功不稳定的问题,根据DOE试验设计方法,对运用该钢正火温度(870~910℃)、奥氏体化温度(830~870℃)两项因子、三水平的试验方案快... 针对30CrNiMo(/%:0.30C,0.85Mn,0.25Si,0.015P,0.008S,0.96Cr,0.43Mo,0.78Ni,0.025Al)高强度钢调质棒材冲击功不稳定的问题,根据DOE试验设计方法,对运用该钢正火温度(870~910℃)、奥氏体化温度(830~870℃)两项因子、三水平的试验方案快速寻找到提升冲击功的最佳工艺组合。对比检测结果发现30CrNiMo钢正火温度越高,淬火后组织晶粒度级别越小,对应冲击功越小。运用Minitab工具制作出冲击功响应晶粒度的拟合公式即:21℃纵向冲击功(J)=27.11+7.751×晶粒度(级)。30CrNiMo钢最佳工艺组合为870℃正火+850℃奥氏体化,其冲击功为106 J。 展开更多
