They have made great contributions to urban prosperity, rural development and their country＇s modernization. At present, however, farmer workers face numerous difficulties and problems in income, work safety, social security, vocational training, the schooling of their children and living conditions. To safeguard the legitimate rights and interests of farmer workers, the State Council in March 2006 issued Ideas of the State Council on Solving Farmer Workers-related Problems. In the document, the State Council promises to strengthen and improve leadership over work regarding farmer workers and prioritize the solving of farmer workers-related problems.展开更多

The microstructure changes of under-cooled austenite in the tested steels at different cool- ing rates were studied by the metallographic method cou- pling with the microhardness method. The effect of Nb con- tent on continuous cooling transformation of the tested steels was analyzed. The experimental results show that with the increase in Nb content, the high-temperature and medium-temperature phase transitions were promoted,展开更多

The HGI of 5 mixed coal samples was measured in lab. Because the HGI data of different mixed coal samples change in different ranges, they could not be directly compared with each other. Though normalizing by the relative grindability ratio （RGR）,展开更多

The denitrification efficiencies were studied by modifying the activated carbon fibers （ACF） and changing the Ce-MnOx loading capacity, Ce/Mn molar ratio and operating conditions respectively. Ce-MnOx/ACFN as a SCR denitrification catalyst has good activity at 70-110℃. The denitrification efficiency increases with rising temperature, and it improves obviously after the ACF is modified by nitric acid. With the increasing of Ce-MnOx loading capacity and Ce/Mn molar ratio, the denitrification efficiency increases firstly and then decreases; but with the increasing of NH3/NO molar ratio in the inlet flue gas, it increases firstly and then tends to be stable. When the volume fraction of vapor in the inlet flue gas is above 8% the denitrification efficiency decreases with the vapor volume fraction increasing.展开更多

When applied in a multi-core computer, the optimiza- tion method can achieve multithreading concurrent operations, thereby improving the efficiency of com- putation obviously. The initial speed-path of Ni-Ti al- loy wire dieless drawing was optimized in an eight-core computer by using the optimization method. Com- pared with a method based on MATLAB program, the operation time of the optimization method is only about 1/8 as long as that of the former. Experimental results show that after adopting the optimized speed-path, the length of diameter fluctuation is about 24 mm, which is far less than that of other speed-paths such as the S-line style or linear path.展开更多
