Farmer cooperatives play a huge role in anti-poverty practice, and the results are remarkable. However, there is still room for improvement in the research on the sustainability of poverty alleviation projects of farmers’ cooperatives. To this end, the author uses questionnaire surveys, factor analysis and other research methods on the basis of existing research results to analyze the sustainability evaluation dimensions of farmer cooperatives poverty alleviation projects, and builds an evaluation index system. Taking 28 farmer cooperatives poverty alleviation projects in Lianghe County as an example. An empirical analysis of sustainability was carried out, and the following conclusions were drawn: ①The four common factors of the sustainability evaluation system have greater room for improvement; ②Cooperatives with poor information technology factors have relatively poor comprehensive scores for the sustainability of poverty alleviation projects. The research results not only help farmers create more material wealth, but also help realize the strategy of rural revitalization. At the same time, it may enrich the theoretical connotation of anti-poverty, and make corresponding theoretical contributions to the theory of rural revitalization and sustainable development.

A beam of ions of mass greater than a few atomic mass units and with sufficient energy can remove atoms from the surface of a solid material at a useful rate. A system used to achieve this purpose under controlled atmospheres is called an ion miliing machine. An ion milling apparatus presently available as IMMI-III with a IMMIAC was used in this investigation. Unless otherwise stated, all the micro milling operations were done with Ar+ at 6kv using a beam current of 100 μA for each of the two guns, with a specimen tilt of 15° from the horizontal plane.It is fairly well established that ion bombardment of the surface of homogeneous materials can produce surface topography which resembles geological erosional features.
