论人的素质与社会发展的同步性

论文从社会形态发展史出发，说明人的素质是一个动态的社会历史范畴。人是主体性与受动性的统一，作为社会主体，高素质人才将是知识经济社会发展的决定性因素之一；人的受动性决定了其自身素质必须与社会历史的发展相同步。这在当今时代不仅具有客观必要性，又具有现实紧迫性。

含源电路欧姆定律的推广及其应用

本文用含源电路的欧姆定律概括了均匀电路的欧姆定律、全电路的欧定律和基尔霍夫第二定律;并将以上结果从稳恒电流电路中推广到了暂态过程和磁路中去,从而突出了“路”的共性及宏观基本规律。同时建立了对“路”统一、实用的符号规约。     

PIXE and INAA studies on ancient potteries from Guangfulin relics in Shanghai

This paper reports the study of ancient potteries unearthed from the Guangfulin site in Shanghai. From the external features of these potteries, archeologists can classify them into two different cultural types: Liangzhu culture (local culture) and a new culture which might be derived elsewhere, but they can not recognize whether they were produced in the same place. Proton induced X-ray emission (PIXE) and instrumental neutron activation analysis (INAA) were used to measure the chemical compositions of the samples and the results were analyzed using multivariate statistics. We found that the two methods can complement each other and their database can be mutually referenced in the study of ancient potteries. Experimental results show that the compositions of the potteries from the two cultural types are different, which means that the materials for ancient potteries of new culture originate from elsewhere. This supports the archaeologists’ speculation that a group of ancient people migrated to Shanghai from some other places 4000 years ago.
