摘要：The multi effects of the grouping were rarely discussed under the context of the TCFL. This essay is to examine the application of grouping by language proficiency and within-class grouping based on a case study. It aims to fred out an optimal grouping system in the TCFL classroom based on the practical experience. It begins with a brief introduction on the history of TCFL and the objectives of this essay. A theoretical evidence of adopting grouping in MFL context is followed in the second section. On the basis of provided background information, grouping by language proficiency and within-class grouping are discussed and analysed with the case study in the following sections. Then it comes to the conclusion of the effects of these groupings in TCFL and recommendations for future researches.

摘要：As shown in the many disputes occurring in reforms to collective forest tenure, reforms aimed at clarifying property rights that follow the contract responsibility system for arable land are not wholly compatible with the informal system of property rights followed in village communities up to the present. This highlights the fact that the existing theory of collective property rights no longer provides a sufficient or effective interpretation of the property rights game in the practice of collective forest tenure. Further, the existing institutional arrangements for collective property rights are conducive neither to the resolution of disputes over forest tenure nor to the sustainable management and utilization of forest land. Therefore, it is necessary to develop a more inclusive analytical framework for rural property rights： village communal ownership. This highlights the village community as the main force in the practice of property fights and integrates the communal ownership values accumulated and inherited in the course of village transition. The introduction of a rational mechanism developed through the practice of village communal ownership may be able to further improve and encourage the reform of rural property fights in China, leading to the construction of a modem system of rural property rights involving clear title to the land.

摘要：A mathematical model of gear tooth profiles using the ellipse curve, whose curvature is convenient to control by changing the mathematical parameters as its line of action, was built based on the meshing theory. The equation of undercutting condition was derived from the model. A special epicycloidal tooth profile was also presented. An example gear drive with variation of the ellipse parameters was taken to illustrate the proposed method. The contact ratio of the gear drive designed by the proposed method was analyzed. A comparison of the property of the gear drive designed with the involute gear drive was also carried out. The results confirm that the proposed gear drive has higher contact ratio in comparison with the involute gear drive.

摘要：In this paper, we reported a solvothermal method for the synthesis of octahedral Pt-Cu bimetallic alloy nanocrystals （NCs） with tunable composition. Inspired by the result from our previous exploration on octahedral Pt-Cu alloy NCs that Cu contents can be tuned from 10 % to 50 %, we further tuned the Cu portion from 50 % to 75 % by simply introducing n-butylamine in the reaction system. It is believed that n-butylamine plays a key role in breaking through a thermodynamic constraint in the formation of Pt-Cu alloy nanocrystals （NCs）. The synergistic effect of underpotential deposition-like Cu reduction and the different complexion abilities of amine group of n-butylamine with two metal species effectively tuned the reduction kinetics, by which each reduced Pt atom is able to catalyze reduction of more Cu atoms and be fully covered with 12 Cu atoms in the Pt-Cu alloy crystal, while Cu precursor is not able to be reduced solely and bind solely with Cu atoms, resulting in the successful tuning of Cu composition from 50 % to 75 %. In addition, we investigated the electro-catalytic activity of Pt-Cu bimetallic alloy NCs with different composition in electro-oxidation of methanol. The as-prepared PtCu3 NCs exhibit excellent electro-catalytic performance and stability in comparison with commercial Pt black and other compositional Pt-Cu alloy NCs.
