It's no exception with government accounting. Since 1998, China's current budget accounting system has been acting as government accounting. Basically, it fulfilled the needs of relevant government accounting. The government accounting integrated with budget accounting. As time passes by, the current budget accounting can not meet the deepening globalization of the market economy nor the developing economic and political environment in terms of the definition of objectives, choices of basic accounting, offering of accounting information. In recent years, public finance reform, transformation of government functions, the public consciousness and other factors call for higher needs for the new government accounting. The current budget fails to provide enough government accounting information that the public need. In 2011, China started a pilot of performance management and performance budgeting in the country. The efficient use of public funds, the profits, and the effectiveness of public information draw more users' attention. It becomes more important for the govemrnent accounting larovidin~ information of performance evaluation.展开更多

The effects of the sol-gel method on the specific surface area, catalytic activity, desorption, and reduction performances of catalysts were investigated with BET, TPR, and TPD. Compared with the catalyst prepared by the impregnation method, the results indicated that the catalysts prepared by the sol-gel method had larger specific surface area, showing higher catalytic activities and exhibiting perfect desorption and reduction performances. In addition, the modification effects of adding La were studied, and it was found that the 0.75NLBT catalyst constituted of 5wt.%Ni-0.75wt.%La was optimal.展开更多

In order to further promote the deepening of the reform of mixed ownership, this paper randomly selects 200 listed state-owned enterprises as research objects, and studies the trends of the financial performance of these enterprises from the mixed state-owned enterprises and non-mixed-modification enterprises in the five years from 2013 to 2017, and compares their various trends. Financial indicators, a comprehensive evaluation of the problems and causes in the reform of the mixed ownership system, and then propose countermeasures to further deepen the reform of mixed ownership based on the research conclusions.展开更多

Treatment with nitric acid helped to increase the amount of functional groups on the surface and hydrophilic nature of carbon support, leading to a homogeneous distribution of Ni nanoparticles. The thermal decomposition products of nickel precursor also played an important role, Ni nanoparticles supported on carbon treated with acid using nickel nitrate as the precursor exhibited the smallest mean diameter of 4.5 nm. With the loading amount increased from 6 wt% to 18 wt%, the mean particle size of Ni nanoparticles varied from4.5 nm to 9.1 nm. The as-prepared catalyst showed a high catalytic activity and a good stability for toluene steam reforming: 98.1% conversion of toluene was obtained with the Ni content of 12 wt% and the S/C ratio of3, and the conversion only decreased to 92.0% after 700 min. Because of the high activity, good stability, and low cost, the as-prepared catalyst opens up new opportunities for tar removing.展开更多
