At present,China's grain production is increasing,the supply and demand structure of grain market is not balanced,and the ineffective supply due to the lack of market supply and demand has caused the problem of structural surplus and structural shortage.And price and quality difference of domestic and international grain is obvious,and the agricultural products in China are overstock,so the reform of agricultural supply side based on food security must be implemented. To adjust structure,reduce stock,reduce cost,increase quality,promote the primary,secondary and tertiary industries convergence will become the focus of China's agricultural supply side structural reform,and we can develop the ecological agriculture,improve the competitiveness of the grain market in price and quality,to ensure food security for the nation.展开更多

Through the food production,storage and circulation,this paper describes the role of food science and technology innovation in food security,and further points out the problems of food science and technology innovation system in Hubei Province,such as disconnection between food science and technology innovation research and food production as well as economic development,backward management system failing to adapt to the needs of agricultural transformation,and low conversion rate of food scientific and technological innovation. Based on this,this paper sets forth the recommendations for food security in Hubei Province.展开更多

The analysis results show that the grain price goes through a change of early rising and later reducing during1990-2014, and smoothly fluctuated in recent years with a downward trend; grain price and CPI fluctuations have a consistent trend, but the grain price volatility is ahead of CPI fluctuation; grain price has positive influences on the CPI; there is a longterm equilibrium relationship between them, namely,grain price is a significant cause of CPI fluctuation. Therefore, we should take various measures to stabilize grain price in order to stabilize the CPI.展开更多

However,the contradiction between a large population and little land,the shortcomings of the household contract responsibility system and the current rapid development of industrialization and urbanization,make problems concerning farming increasingly prominent. To build a new agriculture business entity,the development of agricultural moderate scale operation is imperative. Based on this,this paper analyzes the insecure moderate scale of food and the impact of moderate scale operation of food,and puts forth recommendations for promoting moderate scale operation of food.展开更多

In this paper, we investigated the charge transport through single-molecule benzene dithiol(BDT) junction with different connectivities using mechanically controllable break junction(MCBJ) technique. By further improving the mechanical stability and the electronic measuring component of the MCBJ set-up, we obtained the conductance histograms of BDT molecules(BDTs) from the statistical analysis of conductance-distance traces without data selection. By tuning the connectivity, the conductance of BDTs is determined to be 10^(-1.2)G_0, 10^(-2.2) G_0 and 10^(-1.0)G_0 for para, meta, and ortho connectivity, following the trend that ortho-BDT >para-BDT >meta-BDT. Furthermore, the displacements of the junctions followed the trend that para > meta > ortho, suggesting the charge transport through the molecules via the gold-thiol bond.The different trends between conductance and displacement for different connectivities suggests the presence of destructive quantum interference effect on meta-BDT, which provides the experimental evidence for the quantum interference effect through single-phenyl molecular junctions.展开更多
