Lithium iron phosphate is the recent high-profile of the lithium battery cathode material, as opposed to conventional lithium-cobalt batteries, the lithium-iron battery characteristics are long life, high safety, good heat level, and can withstand 3 5C, and even higher charge-discharge rate, while the use of lithium iron battery raw materials are not rare, you can significantly reduce costs. Super-capacitors have a stable voltage, stable and full-vehicle power systems, protection of vehicle electronics and extended battery life features. It need not destroy the car line. Do not change the original design, easy to install, direct bridging car battery so that the original battery into a high-power batteries, to enhance an instant high- power output, improving vehicle ignition effect, increase engine combustion efficiency and increased power. Reduce fuel consumption. Combination of lithium iron phosphate battery and super- capacitors as an energy saving device. Hope to use this energy- saving device to reduce engine fuel consumption, improve engine exhaust and reducing air pollution. Researchers found that if no energy-saving equipment installed, the engine exhaust components are still up to 2 *** hydrocarbons (such as benzene), 0.07 vol.% CO exist, but, if installation of energy-saving equipment, engine exhaust components in the composition of hydrocarbons and CO have been very few ingredients and no benzene was detected. Energy-saving device can increase the fuel efficiency of car engines. In the seven- seater 2500cc car were installed an energy-saving device. The increased fuel efficiency about 20% to 12%, when the installation of energy efficient device and speed is at 50km/hr to 90km/hr range.

Chinese Geographical Science 2005年第4期15卷 348-354页

Chaohu Lake, located in the central Anhui Province, is one of the five largest fresh lakes in China. Now it is one of the three most eutrophication lakes in China. The deterioration of its water quality has influenced the sustainable development of society, economy and environment of Hefei City, the capital of Anhui Province. A series of measures have been carried out to control its eutrophication, but it is still serious. On the basis of the lake water quality data from 1984 to 2003, the causes of the eutrophication of Chaohu Lake are analyzed. Studies indicated that the suitable natural conditions and human activities played a crucial role in the process of the eutrophication of Chaohu Lake. A great amount of industrial, agricultural and domestic sewage discharged into the lake is the main cause of eutrophication in the lake. Land use, soil erosion and shoreline collapse destroyed the watershed eco-environment and the terrestrial ecosystem of Chaohu Lake. And the building of Yuxi Gate extends the sluggish of the nutritious substance and speeds up the process of the eutrophication. From the view of systematic engineering and watershed ecology, a series of the countermeasures have been put forward to control the eutrophication.

AIM: To investigate the effect of synbiotics, i.e. probiotics and prebiotics mixture, on the gut microbial ecology and digestive enzyme activities in rats. METHODS: Forty-eight SD rats weighing about 280 g were used in this study. Rats were divided into three groups according to the contents of probiotics and prebiotics mixture in the feed as control, low and high dose groups. The duration of the experiment was 8 wk. RESULTS: Compared with the control group, thefecal Lactobacillus and Bifidobacterium counts were significantly increased and the fecal Coliform organism counts were markedly reduced in the low and high dose groups. Concerning the digestive enzyme activity of jejunum, only lactase activity increased in low dose group. However, significant increase of lipase, lactase, sucrase, and isomaltase activities were observed in high dose ***: Intake of low and high dosages of probiotics and prebiotics mixture significantly improved the ecosystem of the intestinal tract by increasing the probiotics population and digestive enzyme activities in rats.

Comparative proteomic study and functional analysis of translationally controlled tumor protein in rice roots under Hg^(2+) stress

So far, very little is known about mercury stress-induced intercellular metabolic changes in rice roots at the proteome level. To investigate the response of rice roots to mercury stress, changes in protein expression in rice roots were analyzed using a comparative proteomics approach. Six-leaf stage rice seedlings were treated with 50 μmol/L HgC12 for 3 hr; 29 protein spots showed a significant changes in abundance under stress when compared with the Hg2＋-tolerant rice mutant and wild type （Zhonghua 11）. Furthermore, all these protein spots were identified by mass spectrometry to match 27 diverse protein species. The identified proteins were involved in several processes, including stress response, redox homeostasis, signal transduction, regulation and metabolism; some were found to be cellular structure proteins and a few were unknown. Among the up-regulated proteins, OsTCTP （translationally controlled tumor protein） was chosen to perform hetereologous expression in yeast which was presumed to participate in the Hg2~ tolerance of rice, providing evidence for its role in alleviating Hg2~ damage. Among the many tests, we found that OsTCTP-overexpressed yeast strains were more resistant to Hg2＋ than wild-type yeast. Thus, we propose that OsTCTP contributes to Hg2＋ resistance. Here we present, for the first time, the functional characterization of OsTCTP in connection with Hg2＋ stress in plants.

Adaptive Nonlinear Optimal Compensation Control for Electro-hydraulic Load Simulator

引用

Chinese Journal of Aeronautics 2010年第6期23卷 720-733页

作者： Yao Jianyong Jiao Zongxia shang Yaoxing Huang cheng National Key Laboratory of Science and Technology on Holistic Control Beijing University of Aeronautics and AstronauticsBeijing 100191China

Directing to the strong position coupling problem of electro-hydraulic load simulator (EHLS), this article presents an adaptive nonlinear optimal compensation control strategy based on two estimated nonlinear parameters, viz. the flow gain coefficient of servo valve and total factors of flow-pressure coefficient. Taking trace error of torque control system to zero as control object, this article designs the adaptive nonlinear optimal compensation control strategy, which regards torque control output of closed-loop controller converging to zero as the control target, to optimize torque tracking performance. Electro-hydraulic load simulator is a typical case of the torque system which is strongly coupled with a hydraulic positioning system. This article firstly builds and analyzes the mathematical models of hydraulic torque and positioning system, then designs an adaptive nonlinear optimal compensation controller, proves the validity of parameters estimation, and shows the comparison data among three control structures with various typical operating conditions, including proportion-integral-derivative (PID) controller only, the velocity synchronizing controller plus P1D controller and the proposed adaptive nonlinear optimal compensation controller plus PID controller. Experimental results show that systems' nonlinear parameters are estimated exactly using the proposed method, and the trace accuracy of the torque system is greatly enhanced by adaptive nonlinear optimal compensation control, and the torque servo system capability against sudden disturbance can be greatly improved.
