The dissertation presents a new vector control method based on fixed voltage mode, which is designed by aiming at the defects in traditional vector control methods of traction motor, which can′t meet the need of high speed torque′s saltation. Under the mode of fixed voltage amplitude of the traction converter, the method presented can achieve the real－time control of high speed torque′s saltation of the traction motor, through the way of combining the high－speed change of converter′s voltage phase with the modified value of the magnetic flux feedback. The results are achieved through theory analysis and simulation experiment, which proves the feasibility and advantage of the control method.

KN－R simulated wastewater is treated by using manganese oxides extracted from spent zinc－manganese dry battery and MnO2 respectively. The experimental results show that the initial pH value is the key factor affected decolorization. The removal efficiencies of color are over 75 ％ under the conditions of pH＝2.0, dosages of manganese oxides and MnO2＝80 mg／L, reaction time＝30 min. It is found that the decolorization effect of wastewater using manganese oxides treatment is superior to that of wastewater using MnO2 treatment, which provides a new way of resource utilization of spent dry battery.

The effect of different molecular－weight Polyvinylpyrrolidone (PVP) on PCR efficiency has been researched into by undertaking the 110 bp, single－stranded DNA amplification with quantitative real－time polymerase chain reaction (QPCR). The results indicates that 0.5％ PVP K－30, PVP 8000, PVP 58000 and PVP 630000 could effectively enhance the PCR efficiency, and the ability of different molecular－weight PVP to improve PCR efficiency is PVP 630000, PVP 58000, PVP K－30 and PVP 8000, respectively. However, PVP K－40 could significantly inhibit the generation of PCR product. In addition, the results of melting curve showed that 0.5％ PVP 630000 could dramatically reduce the Tm value of PCR product. It suggestes that PVP 630000 could interact with DNA template to reduce the stability of DNA conformation, promote the unwinding of DNA template in the denaturation stage of PCR, then enhance the PCR efficiency. The results reveal that the effects of different PVP on the PCR efficiency is closely related to the molecular－weight.

ObjectiveTo know iron deficiency anemia status and its trend of development in the primary and middle school students in Wuhan and to provide a scientific basis for the education and health sectors. The subjects are the boy and girl students of 7, 9, 12, 14 and 17 years old in 2010 and 2005, in Wuhan City. MethodsUsing screening for anemia of WHO standard of 1972. The degrees of anemia were divided into ＂borderline＂, ＂mild＂, ＂moderate＂. Comparative analysis of the two investigation anemia rates and anemia degrees of the boy and girl students in urban and rural areas were made twice. ResultsWithin five year from 2005 to 2010, the anemia rate of rural students has dropped dramatically in Wuhan City, while that of urban students has relatively risen substantially. Most of them suffer from borderline anemia. Borderline anemia rate increased in most age groups, mild anemia rate decreased, the degree of anemia overall decreased in boys. The urban and rural areas were opposite. And the degree of anemia overall increases. Urban students and rural students in early schooling (7 and 9 years old) and in later period of puberty(14 and 17 years old) are more prone to anemia rate increase and anemia severity. The trend for the rural boy＇s rate of anemia is optimistic. The urban girl＇s is the highlight of the weak groups, not only with the increasing degree of anemia, but also with deterioration in the severity. ConclusionThe relevant departments should pay great attention to deterioration of the urban students＇ anemia and focus on urban student(especially girls) groups, especially in early schooling and puberty stages.

The dissertation has made a research into the finals of men′s team, the all－around and other six individual events of 42nd annual world gymnastics championships by the literature material method, video observation method and mathematical statistics method. The dissertation has analyzed developing state, trend and pattern change of world′s men′s gymnastics in the new cycle of Olympic Games and new scoring rules. The results show that the combat between China and Japan in the new cycle of Olympic Games and new scoring rules matters greatly. Chinese advantage reduces. Almighty items enter a Japanese era. China lacks of an obvious successor, and gap of comprehensive strength competitiveness between China and Japan is too great. In the six individual finals, it is not the condition that the strong wins easily. The countries of the second and third classes also share competition of gold medals. But rings and parallel bars events are still in ＂Chinese era＂, being the best in specifications, quality, layout, difficulty, and stability of performance and exhibiting powerful dominating position. After keeping silence for seventeen years, China rose again in horizontal bar, interpreting gymnastic beauty by using eastern wisdom. China is weakened in the floor exercise, the side horse and vault due to improvement of competition system. No Chinese sportsman enters the finals, which shows the weakness of Chinese players who prefer favorite events.
