The purpose of this paper is to develop new types of anchor bolt materials by adding corrosion-resistant elements for alloying and microstructure regulation.

Three new anchor bolt materials were designed around the 1Ni system. The stress corrosion cracking resistance of the new materials was characterized by microstructure observation, electrochemical testing and slow strain rate tensile testing.

The strength of the new anchor bolt materials has been improved, and the stress corrosion sensitivity has been reduced. The addition of Nb makes the material exhibit excellent stress corrosion resistance under –1,200 mV conditions, but the expected results were not achieved when Nb and Sb were coupled.

The new anchor bolt materials designed around 1Ni have excellent stress corrosion resistance, which is the development direction of future materials. Nb allows the material to retain its ability to extend in hydrogen-evolution environments.

As there are different interpretations of the object of study in the preface to the first edition of Capital (Volume I) by Karl Marx, disagreements arise over the object of study on political economy, which becomes a “difficult problem.” The purpose of the paper is to bring a new solution to the “difficult problem.”

Based on the analysis of the logic of the original text, the authors attempted to give a new interpretation of the “difficult problem” by analyzing the structure of Capital. The object of study of political economy is “the relations of production in the broad sense” of the capitalist mode of production.

It comprises relations of production in the narrow sense and exchange relations in the broad sense, and the latter can be divided into exchange relations in the narrow sense and distribution relations. The three of them correspond to Volume I, II and III of Capital, respectively. Consumption in “the four-section theory” is not studied by the political economy.

And the four-section theory is not a part of the theory of Marxist economics but a part of the classical economics criticized by Marx. Therefore, the object of study of socialist political economy with Chinese characteristics is “the relations of production in the broad sense” regarding the socialist mode of production with Chinese characteristics, which is different from the capitalist relations of production in the broad sense.

The purpose of this paper is to apply the theory of cultural diplomacy to explore and explain the role and function of the Confucius Institution project and its implications for understanding of China's soft power projection.

This paper first presents the theories of soft power and cultural diplomacy as an analytic framework. It then delineates an interpretative illustration of the CI project as a platform for China's cultural diplomacy. The paper concludes with a discussion of the CI project's implications for understanding of China's soft power projection.

The paper argues that the Confucius Institute project can be understood as a form of cultural diplomacy that is state‐sponsored and university‐piloted, a joint effort to gain China a more sympathetic global reception. As such, the Confucius Institution project involves a complex of soft power techniques. However, it is not entirely representative of soft power capability, because the problems embedded in the project and in the wider society run counter to the Chinese government's efforts to increase the Confucius Institutions’ attractiveness and popularity.

This article sheds light on Chinese universities in the role of “unofficial cultural diplomats.” On this topic, further research may need to explore more fundamental issues that bear far‐reaching significance and impact, i.e. the mechanics of Chinese university involvement in Confucius Institutes. Interesting questions arising from this study may help open up a wider spectrum of research topics for understanding the university‐state relationship, cross‐border higher education, as well as the possibilities and limits of educational globalization. At this stage, this article serves as a start to move scholarship in that direction.
