摘要： With the increasing income of the rural population in Northwest China,people’s sense of happiness and gain is also increasing.However,the improvement of housing conditions is lagging behind the increasing income levels.In recent years,the government and owners have paid much attention to this issue.The local government has successively issued relevant guidelines and policies to encourage owners to reconstruct their houses and improve their housing conditions.Before improving housing conditions,the existing housing problems must be identified.In order to have a comprehensive and in-depth understanding of the problems of rural residential buildings in Northwest China and to propose corresponding solutions,90 representative rural residential buildings of three provinces in Northwest China have been selected for investigation,and mass data have been obtained.Upon analyzing these data,it has been found that there are problems in five aspects of rural residential buildings in Northwest China:architectural style and functional space layout,energy utilization and dissipation,design,construction,as well as structural safety and seismic measures.Valid solutions are proposed to address these problems,which can also provide a reference for the government and enterprises engaged in the architecture,engineering,and construction(AEC)industry in rural areas.

摘要： For a long time, the supply of drinking water to the island of Mar was ensured by drilling and wells. The advance of the salt wedge led the populations to stop the exploitation of the drilling due to the accentuation of the salinity of the water characterized by high fluorine content. The marine environment and the rainfall deficit of recent decades as well as population growth have highlighted the sensitivity of this resource. The objective of this article is to study the drinkability of the water supplied by the drilling and the wells of the island of Mar. for this, water samples were taken in the Continental Terminal and their analysis made in situ or in the laboratory. Data processing was done by using Surfer 11 and ArcGIS software. It was emerged from this study that the drop in the piezometric level caused an entry of salt water. The mineralization of the water follows a decreasing trend from areas with marine influence inland. Groundwater in certain areas is generally of good quality with some sources of pollution linked to salinity but also to high levels of nitrate, chloride and fluorine. The island of Mar being confronted with a problem of drinkability of groundwater, the alternative would be to proceed to a transfer of better quality water from nearby areas after a hydrogeological and physico-chemical study of these waters in relation to their fitness for consumption.

摘要： Bidding is a key link during the implementation of a construction project.For the same construction project,there are usually multiple construction companies bidding together to obtain the right to contract for the project.However,there are still various irregularities in the bidding stage.This article analyzed the above problems and proposed a management strategy for the optimization of bidding,looking forward to improving the quality of bidding management of construction projects,solving various illegal bidding problems,and purifying the environment of bidding management.

摘要： Objective:To investigate the effect of intensive psycho1ogical nursing on the mood and coping ways of spinal tuberculosis patients.Methods:The clinical data of 102 patients undergoing spinal tuberculosis surgery in our hospital from February 2017 to January 2020 were retrospectively analyzed.A11 the cases were grouped according to different nursing plans,patients who received routine care were included in the control group(n=50),and the ones with intensive psychological care were included in the observation group(n=52).Compare negative emotions after nursing[assessment using self-assessment scale of anxiety(SAS),depression self-assessment scale(SDS)]and solutions[assessment using medical response questionnaire(MCMQ)]of the two groups.Results:After nursing,the SAs,SDs scores,avoidance and yield scores of the two groups were reduced,and the coping scores were increased,and the change of the observation group was greater than that of the control group,the difference was statistically significant(P<0.05).Conclusion:Spinal tuberculosis surgery patients were treated with intensive psychological care,which can relieve patients''negative emotions,improve solutions and are worthy of clinical use.

摘要： In this paper, we study the existence of nodal solutions of the following general Schödinger-Kirchhoff type problem: where a,b > 0, N ≥ 3, g : R → R+ is an even differential function and g''(s) ≥ 0 for all s ≥ 0, h : R → R is an odd differential function. These equations are related to the generalized quasilinear Schödinger equations: Because the general Schödinger-Kirchhoff type problem contains the nonlocal term, it implies that the equation (KP1) is no longer a pointwise identity and is very different from classical elliptic equations. By introducing a variable replacement, we first prove that (KP1) is equivalent to the following problem: whereand G-1 is the inverse of G. Next, we prove that (KP2) is equivalent to the following system with respect to : For every integer k > 0, radial solutions of (KP1) with exactly k nodes are obtained by dealing with the system (S) under some appropriate assumptions. Moreover, this paper established the nonexistence results if N ≥ 4 and b is sufficiently large.

摘要： English writing can objectively reflect students' ability of thinking, organizing and expressing.Chinese students always think in Chinese way and use English words to express their ideas in Chinese practice. Students may adopt word-for一word translation strategy while writing. We all know two typical jokesabout Chinglish："Good good study, day day up" and "You ask me, me ask who?" Such sentences are very ri-diculous and they can't be understood by foreigners, which reflect a serious problem exiting among Chinesestudents. This phenomenon is called Chinglish一Chinese English, an obstacle of improvement of students'writing ability. Chinglish is mainly caused by the strong interference of the mother tongue一Chinese.Typical errors are employed in the article to illustrate the causes and remedies of Chinglish in students' writ-ing, including the following aspects-vocabulary, sentence structure and textual structure. Based on the analysis, the paper will offer some practical solutions for conducting English writing courses, then the most essential way to reduce Chinglish are to build students' awareness of the distinction between English and Chinese,to increase the exposure to the authentic English and practice writing more often in order to adjust students'Chinese thinking mode to that of English, with the aim of helping students avoid Chinglish so as to improvetheir writing ability.

摘要： In recent years, with the relevant state departments paying more attention to reform of personnel system, personnel system reform of China's universities in full swing. Personnel system is an important partof the universities management system, the reform of personnel system is benefit to the development ofcolleges and universities career, and it relates to success of the education in colleges and universities. Thispaper analyzes problems in current personnel system reform of China's colleges and universities, then putsforward thinking and strategies, striving to make some useful exploration on the university personnel system reform.
