摘要：
Objects: Analysis the correlation of the step index, 1000m run, 12min run with maximal oxygen uptake(VO(2max)) in high school boys, for the purpose of providing students, teachers and parents with more convenient and effective testing method to command students' physical health status. Subjects and Methods: Adopted simple random sampling, and extract boys of seventh grade, eighth grade, sophomore and junior from two urban and two rural schools in Changsha area as subjects, with 240 in total. Measured the students' step index, 1000m, 12min run, and directly measured their VO(2max); then calculated and processed data by such methods as comparative method and correlation analysis. Results: 1) Step index, which has no statistics relativity with the VO(2max), 1000m run and 12min run, also, can not reflect discipline of ageing changes. 2) The correlation coefficient of 1000m run with the maximal oxygen uptake is -0.716, is high negative correlation(P<0.01). Similarly, the correlation coefficient of 1000m run with 12min run is -0.77, is high negative correlation too(P<0.01). The correlation coefficient of 12min run with VO(2max) is 0.731, is highly positive correlation (P <0.01). Conclusions: 1) The step index cannot exactly reflect endurance quality level and cardiovascular function level in high school boys; 2) Both 1000m and 12min run may be acted as the indexes to indirectly determine VO(2max), furthermore, there is much stronger replacement within.

摘要：
In this paper, we study reward-risk ratio models under partial known message of random variables, which is called robust (worst-case) performance ratio problem. Based on the positive homogenous and concave/convex measures of reward and risk respectively, the new robust ratio model is reduced equivalently to convex optimization problems. Such model exhibits a mix-max optimization framework.

摘要：
The inhibited or enhanced uptake of heavy metals by iron plaque has been observed. The relationship between amounts of adsorption and accumulation of heavy metals and iron plaque on roots of wetland plant is still unclear. This study examined the effects of iron plaque on lead (Pb) absorption and translocation between underground and above-ground parts of a wetland plant species. Broad-leaf cattail (Typha latifolia L.) was grown in soil for four weeks under waterlogged conditions in a greenhouse. The soils were treated by Pb as lead nitrate at four levels (0, 100, 500 and 1000 mg Pb·kg-1) and waterlogged for two weeks. The results showed that the amount of iron plaque in the treatment with addition of 500 mg Fe·kg-1 was general higher than that of the treatment with addition of 100 mg Fe·kg-1, Lead concentrations in both shoots and roots treated by 500 mg Fe·kg-1 was more than that of the treatment with 100 mg Fe·kg-1. When the ratio of added Fe and Pb was 1, the accumulation of Pb in plants was higher than that of other treatments at the same Pd level. Appropriate amount of iron supplied will benefit lead accumulation in plant, which help the removal or stabilization of lead in constructed wetland.

Available transfer capability (ATC);smoothing newton method;static security;wind generation
摘要：
The approach of available transfer capability (denoted as ATC) incorporating wind generation has been paid very high attention since the development of wind generation. Based on the maximum function, this paper presents an ATC model. The characteristic of the new model is twofold. First, it considers wind turbines connected to power system and static security of power system simultaneously. Second, it is a system of semismooth equations and can be solved easily. By using the smoothing strategy, a smoothing Newton method is adopted for solving the proposed new ATC model. Numerical simulation results of the IEEE 30-bus and 118-bus system show that the new model and algorithm are feasible and effective. The impact of wind turbines connected to power system on ATC is also analyzed.

摘要：
Research on virtual enterprise has been a hot and difficult field since "virtual enterprise" was firstly proposed by Kenneth Preiss, etc in the late 20(th) century. Looked back relevant literatures, it can be found that the evaluation measure of VEP (Virtual Enterprise Performance) is very important about the virtual enterprise decision-making, but so far theoretical circles have not solved the problem yet. In the article some relevant literatures are firstly reviewed and then the evaluation measure mechanism of VEP is analyzed, finally an evaluation measure model was proposed, which provides a new methodology measuring VEP.

摘要：
Batch and column experiments were conducted to determine whether zerovalent iron (ZVI) and sulfate reducing bacteria (SRB) can function synergistically and accelerate pollutant removal. Batch experiments suggest that combining ZVI with SRB can enhance the removal of U(Ⅵ) synergistically. The removal rate of U(Ⅵ) in the ZVI+SRB combining system is obviously higher than the total rate of ZVI system and SRB system with a difference of 13.4% at t=2 h and 29.9% at t=4 h. Column experiments indicate that the reactor filled with both ZVI and SRB biofilms is of better performance than the SRB bioreactor in wastewater basification, desulfurization and U(Ⅵ) fixation. The results imply that the ZVI+SRB permeable reactive barrier may be a promising method for treating subsurface uranium contamination.
