ARTICLE Research on the Leading Value Drive of Rural Homestead Transfer under Rural Revitalization--Based on the Evidences of China

With the development of urban-rural integration in China,the functional value of homestead bases has evolved from a single residential security value to a multiple composite values,and the property income of homestead bases has gradually become the value driver of transfer and the intrinsic demand of farm households.This paper takes Baitafan of Jinzhai County,Chongqing City,and Xiaofang Yu Village of Ji County as examples for in-depth discussion,and finds that the dominant value drivers of home base transfer mainly include three kinds:capitalization income,commercialization income,and non-farm employment income.The study concludes that it is important to give full play to the resource endowment effect and identify the dominant value of home base transfer according to local conditions to promote the standardized home base transfer and implement the rural revitalization strategy.

Assessment of wear micromechanisms on a laser textured cemented carbide tool during abrasive-like machining by FIB/FESEM

The combined use of focused ion beam(FIB)milling and field-emission scanning electron microscopy inspection(FESEM)is a unique and successful approach for assessment of near-surface phenomena at specific and selected locations.In this study,a FIB/FESEM dual-beam platform was implemented to docment and analyze the wear micromechanisms on a laser-surface textured(LST)hardmetal(HM)tool.In particular,changes in surface and microstructural integrity of the laser-sculptured pyramids(effective cutting microfeatures)were characterized after testing the LST-HM tool against a steel workpiece in a workbench designed to simulate an external honing process.It was demonstrated that:(1)laser-surface texturing does not degrade the intrinsic surface integrity and tool effectiveness of HM pyramids;and(2)there exists a correlation between the wear and loading of shaped pyramids at the local level.Hence,the enhanced performance of the laser-textured tool should consider the pyramid geometry aspects rather than the microstructure assemblage of the HM grade used,at least for attempted abrasive applications.
