旨在为大豆加工厂仓型选择提供参考，以仓容1.5万t的3 000 t/d的大豆加工厂为研究案例，对比分析了大豆粕混凝土立筒仓与机械化房式仓的进出仓工艺和设备，结合国内部分工厂的实际建设和运营数据，总结分析了两种仓型的占地面积、仓容利用率及投资运营费用等。结果表明，相较于混凝土立筒仓结合出仓机方案，机械化房式仓结合强力出仓机方案在控制大豆粕水分含量和存储风险方面具有一定优势，且每年能够节约26.56%的用电成本。以10年的运营期为计算基准，机械化房式仓结合强力出仓机的方案可降低46.2%（对应2 430万元）的费用现值。综上，机械化房式仓结合强力出仓机方案具有投资低、仓容利用率高、运行成本低、维修费用少、维修便利等优点，且物料分级少，品质有保障，可作为投资者的选项。In order to provide reference for the selection of warehouse types for soybean oil processing plants, taking a 3 000 t/d soybean processing plant with a storage capacity of 15 000 t as a case study, the process and equipment of soybean meal concrete vertical silo and mechanized warehouse were compared and analyzed, the floor area, warehouse capacity utilization rate and investment and operation expenses of the two warehouse types were summarized and analyzed based on the actual construction and operation data of some plants in China. The results showed that compared with the concrete vertical silo combined with reclaimer, the mechanized warehouse combined with powerful reclaimer had certain advantages in controlling the moisture content and storage risk of soybean meal, and could save 26.56% of the electricity cost per year. Based on the 10-year operation period, the solution of mechanized warehouse combined with powerful reclaimer could reduce the present value of expenses by 46.2% (corresponding to 24.3 million yuan). To sum up, the solution of mechanized warehouse combined with the powerful reclaimer has the advantages of low investment, high warehouse capacity utilization rate, low operating cost, less maintenance cost, convenient maintenance, etc. ， and less material classification, quality assurance, and it can be used as an option for investors.

旨在为仓储物流行业及油脂加工厂中仓库设计提供借鉴，以库容量10万箱中小包装食用油（5 L小包装、10 L中包装成品油各5万箱）仓库为研究案例，系统分析了两种仓库（平面仓库和自动化立体库）的主要特点，从占地面积、生产成本、建设投资、运营费用等方面对两种仓库的技术方案进行了比较，并对两种仓库进行了经济分析。结果表明：自动化立体库相较于平面仓库能减少66.4%的占地面积，每年能够节约运营成本近50万元；自动化立体库的增量投资收益率为19.01%，增量投资回收期为5.26年，费用现值相比平面仓库低114万元。针对多品种、多拣选、年吞吐量大、产品可追溯性高、衔接工厂MES/ERP系统且持续运营在6年以上的仓库，使用自动化立体库能够显著降低项目总持有成本，降低工人劳动强度，提高发货效率，改进客户体验。In order to provide reference for the warehouse logistics industry and the warehouse design in oil processing plant, warehouse with a storage capacity of 100 000 boxes (each 50 000 boxes of 5 L small packaged oil and 10 L medium packaged oil) was used as a research case, the main features of two types of warehouse (automatic three-dimensional warehouse and flat warehouse) were systematically analyzed, the technical schemes of the two warehouses were compared through warehouse floor space, production costs, construction investment, operation costs and other aspects, their economic analysis was also conducted. The results showed that compared with flat warehouse, automatic three-dimensional warehouse could reduce 66.4% of the floor space, and save operation costs nearly 500 000 yuan per year. The incremental investment return rate of automatic three-dimensional warehouse was 19.01%, the incremental investment payback period was 5.26 years, and the cost present value was 1.14 million yuan lower than flat warehouse. For multi-species, multi-picking, large annual throughput, high product traceability, connecting factory MES/ERP system, and continuous operation in more than 6 years of warehouses, the use of automatic three-dimensional warehouse can significantly reduce the total cost of ownership of the project and the intensity of labor, improve delivery efficiency and customer experience.

为实现油脂生产企业的自动化、信息化，提升工人的劳动生产率，改善生产环境，以华东某3 120 t/d豆粕打包车间为例，分别以全自动装车机与人工装车机进行装车，对比分析两种装车方式建设投资、人工费用、运营维护费用、增量投资收益率、增量投资回收期、费用现值等。结果表明：全自动装车机比人工装车机的5年总体拥有成本低了38.4%，每年能够节约人工费用82.0%，增量投资收益率达到53.4%，且投资风险较低，可节约企业运行过程中现金流成本。对于信息化建设程度要求较高，迫切需要解放劳动力，且持续运营在2年以上的打包项目，采用全自动装车机能够显著降低工厂的总持有成本及工人劳动强度，提高企业的信息化水平，加快货物周转速度。 To realize the automation and informatization of oil production enterprises, improve the labor productivity of workers, and improve the production environment, taking the soybean meal packaging workshop of a 3 120 t/d processing capacity in East China as a case study,fully automatic loading machine and manual loading machine were used to package soybean meal,respectively. The construction investment, labor costs, operation and maintenance costs, incremental investment return rate, incremental investment payback period, and cost present value were analyzed and compared of the two loading method. The results showed that compared with the manual loading machine, the 5-year total cost of ownership of the fully automatic loading machine was 38.4% lower, and it could save 82.0% of the labor cost every year, and the incremental investment return rate reached 53.4%, the investment risk was low, and it could save the cost of cash flow during the operation of the enterprise. For packaging projects with high requirements for informatization construction, urgent need to liberate the labor force, and continuous operation for more than 2 years, the use of fully automatic loading machine can significantly reduce the total cost of ownership of the factory and the labor intensity of workers, improve the informatization level of enterprises, and speed up the turnover of goods.

It is one of the key tasks of science and technology in China to adjust the investment structure of basic research funds and accelerate the construction of multiple investment pattern. The National Natural Science Foundation of China (NSFC) plays an important role in leveraging diversified investment in basic research. At present, the joint funds are the main way for NSFC to guide diversified investment in basic research in China. It is a successful exploration for NSFC to meet national needs, guide diversified investment, promote resource sharing and multilateral cooperation. Nevertheless, on the one hand, the cooperation of the joint funds is limited to state-owned organizations, institutions, and enterprises, but has not been extended to private sectors. On the other hand, the management system and operation mode cannot fully reflect the inherent property of the cooperative investment of the joint funds. Thus, it is suggested that the joint funds break through the boundary between public and private sectors in terms of management philosophy to realize the transformation to the public-private partnership (PPP) cooperation model of R&D; set up a relatively independent "Joint Funds Management Center" to improve the governance system and mechanism; establish and improve the evaluation criteria and mechanism for the utilization of results that are in line with the characteristics of the joint funds. In the new stage of development, it is necessary to solve the long-standing problem that NSFC has been unable to receive donations from society. Based on the analysis that the NSFC's acceptance of social donations is a "public trust" behavior, this study figures out that NSFC should first be given the qualification and identity to accept social donations legally and in compliance. It is suggested to set up a "China Science Fund Public Trust Center" to break through the existing institutional barriers and promote the NSFC to accept social donations. [ABSTRACT FROM AUTHOR]

Objective: To explore the relationship among bullying bystanders’ different behaviors, empathy, and self-efficacy in junior high school students. Methods: Totally 453 students were assessed with the Bullying Bystanders’ Behaviors Questionnaire（BBBQ）, Basic Empathy Scale-China（BES-C） and General Self-Efficacy Scale（GSES）. Correlation analysis and multiple regression analysis were used to explore the relationship among the three variables. Results: The boys got higher scores of promoting bullying behaviors, outsider behaviors and GSES scores than girls, while lower BES-C total scores and emotional empathy scores than girls (Ps <0.01). The scores of BBBQ promoting bullying behaviors and outsider behaviors were negatively correlated with the BES-C scores in junior school students（r=-0.13, -0.13, Ps <0.01）, and the defending behaviors scores were positively with the BES-C scores（r=0.21, P <0.001）. Self-efficacy had a significant moderating effect on the relationship between empathy and defending behaviors, outsider behaviors（β=0. 17, -0.10; ΔR²=0.029, 0.009）. Conclusions: It suggests that the behavior orientation choice of bullying bystanders may be related to empathy and self-efficacy in junior middle school students. Under the condition of high self-efficacy, junior middle school students with high empathy level may be more likely to make victim protection behavior. [ABSTRACT FROM AUTHOR]
