Alkyl imidazole cationic Gemini surfactants (AICGS) with various alkyl chain lengths were used as retarders for dyeing methylene blue (MB) on polyacrylonitrile (PAN) fabrics, with benzyldimethyldodecylammonium chloride (1227) surfactant as a comparison. The exhaustion (E%) of MB on PAN fabrics was investigated at varying surfactant concentrations and dyeing temperatures. Furthermore, kinetic studies on various retarders and 10‐4‐10 AICGS concentrations were carried out. It was found that the retarding dyeing effect of AICGS is stronger when compared with the 1227 surfactant. Moreover, as surfactant concentration increased or the dyeing temperature decreased, E% was reduced drastically. For kinetic studies, the dyeing rate constant increased with an increase in dyeing temperature and a decrease in 10‐4‐10 AICGS concentration, while half‐dyeing time was reversibly decreased.

The financial repression constraints the development of the rural economy, but the financial deepening is good to it. The financial deepening is benefit to overcome the financial repression. This paper puts forward the measures to rural financial deepening in Jilin Province, and the measures are as follows: first is to relax the controls of the interest rate in order to make the rural financial market interest rates liberalize; second, is to lower the capital threshold to enter the rural financial market, and relax the regulation; third is to play "leading function" of the Agricultural Development Bank and agricultural policy insurance institutions, leading more capital into the rural market; Fourth is to establish a mechanism making the capital flow into rural areas; fifth is to reduce the direct subsidies to farmers, and the indirect subsidies are implemented to farmers through the agricultural and political financial institutions.

The development of modern agriculture causes the planter, the processing and the agricultural product circulation to link together closely. The agriculture whose feeble constitution characteristic is obvious not only needs to undertake the output risk (natural disaster), but also needs to undertake the price risk from the second industry and the third industry. The feeble constitution of agriculture and the public goods constitution of agricultural product circulation request government to protect agriculture. The agricultural political insurance is the best choice for the government to protect the agriculture and control the risk of agricultural income. Keywords-Agricultural political insurance Protecting agriculture Study I. THE ANALYSIS OF THE RISK FACED BY FARMERS DURING MODERN AGRICULTURE DEVELOPMENT STAGEModern agriculture is the socialized agriculture which widely uses the means of production, facilities, equipment and modern science provided by the modern science and technology, modern industry to manage the agriculture.The core of the modern agriculture is scientization, the character is commercialization, the direction is intensification, and the means of implementation is industrialization. The "company + farmer cooperative organizations + base + farmers" is the suitable model for the development of Chinese agricultural industrialization.Industrial management of agriculture is the implementation of integrating agriculture and industry. The risks from international markets and the ones from China's primary industry, secondary industry and third industry are all concentrated in the whole industry chain.Agricultural industrialization involves multi-stakeholders such as leading enterprises, dominant product base, farmers, the rural cooperative organizations, intermediary service organizations, and the leading enterprises and farmers are the most basic of the main body. According to market relations, the farmers who sell agricultural products, is the supply side of market transactions; leading enterprises to purchase agricultural products as raw materials for processing valueadded, is the demand side of market transactions. However, the leading enterprises are business entities of the second industry and tertiary industry. The leading enterprises internalize the agricultural industry by the integration of production, supply and sales, and through a contract to ensure a steady supply of quality raw materials so as to effectively avoid the risk from the first industry. Farmers are the main product body of the primary industry, and the risks taken by farmers are far greater than the ones taken by the leading enterprises.It is not possible for the rural households who contract land and manage it dispersedly to invest too many resources to study the market, and instead rely more on rural cooperative organizations and the guidance of leading enterprises to meet the needs of risk reduction. The farmers usually contract with the farmers Cooperation and the leading enterprises by prior, stating the quantity, quality...
