The paper present the development of OE （ocean energy） field in China and outline the new technologies and best practice, resources conditions, construction targets, generation device testing and standard system. The main purpose is to improve the level of China＇s ocean energy development. The Chinese ocean energy test field, which was started in 2008, involved a development divided in three phases （the overall design, construction, demonstration）. The methodology followed in the individual phases is described, and the standardization of testing wave and tidal current energy devices is introduced. The research revealed the development and the shortage of ocean energy technology in China.展开更多

The performances of LPF are controlled by a 1-bit control- voltage, and the cut-off frequency, channel selectivity, and linearity of the proposed filter can be reconfigured accordingly. In order to improve the accuracy of the cut-off frequency, a binary-weigh- ted switched-capacitor array is employed as the auto-tuning circuits to calibrate the RC-time con- stant. Fabricated in TSMC 0. 18μm RF CMOS process, the proposed LPF achieves a measured cutoff frequency of 1.95 and 12.3MHz for WCDMA and GPS/Galileo application with a bandwidth de viation less than 4%. The measured l dB compression points are -3.0dBm and -5.1 dBm respectively for different modes. The core circuit of LPF consumes l mW and 1.6mW for WCDMA and GPS/Galileo respectively. And the proposed LPF occupies an area of 0.78ram2.展开更多

Moreover, developing circular agriculture is in the direction that the international challenges can be dealt with and the development of agriculture in China can be accelerated. This paper has reported current situation of agricultural circular economy, keep energy conservation and pollution reduction, and analyzed the basic thought of developing agricultural circular economy.展开更多

Here, the framework of the standards system and evaluation indicators system for environmental protection products are described based on the present deficiencies in independent innovation, lower levels of standardization, and poor operating effectiveness of such equipment in China with a goal of forcing the development of standardization, seriation and currency used in the environmental protection industry. The results presented here should serve as a reference for the promotion of quality and effectiveness in environmental protection products and equipments.展开更多
