A prompt gamma-neutron activation analysis(PGNAA) system was developed to detect the iron content of iron ore concentrate. Because of the self-absorption effect of gamma-rays and neutrons, and the interference of chlorine in the neutron field, the linear relationship between the iron analytical coefficient and total iron content was poor, increasing the error in the quantitative analysis. To solve this problem, gamma-ray self-absorption compensation and a neutron field correction algorithm were proposed, and the experimental results have been corrected using this algorithm. The results show that the linear relationship between the iron analytical coefficient and total iron content was considerably improved after the correction. The linear correlation coefficients reached 0.99 or more.

在西方哲学思想的嬗变中,人民的政治性是人的本性,政治成为人民“无法超越且只能永远陷溺其中的现世”,而人民作为一个具有主体性意旨的范畴,最深刻的表现是统治与被统治。马克思人民理论的创立及其逻辑的展开打破了传统意义上先验的政治预设,它立足人民的现实境遇,明晰了“人民理性”的哲学原则,将无产阶级作为“真正的人民”,重构其政治范畴、主体范畴以及历史范畴,揭示了人民主体的历史根基在于劳动实践,劳动解放是其超越传统政治性,实现人民现实性与神圣性的根本途径。新时代,习近平总书记从中国具体实践出发,确立“以人民为中心”的发展理念,对马克思人民理论进行了全面性拓展、系统性运用与创造性实践,为马克思人民理论在当代的发展做出了卓越努力。

作者： SUN XiaoFeng GU LiangXian gong ChunLin School of Astronautics Northwestern Polytechnical UniversityXi'an 710072China

The dynamics of a supersonic missile with a deflectable nose are studied. To describe the effects of nose deflection on the dynamic model, theorems of momentum and angular momentum are adopted to develop the translational equation and rotation equation, respectively. Because the exact model is complex, it is simplified. The simplified model suggests that the main influence of nose deflection on the dynamic model is due to the product of the time derivatives of the azimuth angle and the elevation angle, which makes the dynamic model an impulsive differential system. Considering the aerodynamic characteristics a numerical simulation is sufficient to show the open-loop characteristics of the missile.

This article discusses the role that nature plays in ethnic literature and films in the Seventeen-Year Period(1949-66).It takes the story of Daji and Her Fathers as an example and investigates the ways in which nature features in the reconstruction of ethnic identity in the formation of a multiethnic nation as in the case of China.I will explore three aspects:first,the debate on humanism,which was closely related to ethnic minority film production at the time.A central issue of the debate then was the question of“humanistic”-that is,affective,emotional,subjective,and most importantly,natural-expression in literary and art *** minority identity,with its unique status,was given some latitude for humanistic expression and“natural”***,due to ethnic minority groups’special significance in China’s nation-building,a reconstruction of ethnic minority nature became imperative for the People’s Republic of *** reconstruction involves mostly restructuring a“second nature,”or dialectic nature of minority under the socialist *** dialectic nature demands something more than natural,immediate constituents and requires a socially and politically mediated ethnic minority nature that is aligned with multiethnic ***,this dialectic nature is to be formed following Marxist dialectical materialism,mainly through the means of social(ist)labor that changes nature.
