The storage behavior and process of the first delithiation-lithiation of LiCoO2 cathode were investigated by electrochemical impedance spectroscopy(EIS). The electronic and ionic transport properties of LiCoO2 cathode along with variation of electrode potential were obtained in 1 mol·L?1 LiPF6-EC:DMC:DEC electrolyte solution. It was found that after 9 h storage of the LiCoO2 cathode in electrolyte solu-tions,a new arc appears in the medium frequency range in Nyquist plots of EIS,which increases with increasing the storage time. In the charge/discharge processes,the diameter of the new arc is reversi-bly changed with electrode potential. Such variation coincides well with the electrode potential de-pendence of electronic conductivity of the LiCoO2. Thus this new EIS feature is attributed to the change of electronic conductivity of LixCoO2 during storage of the LiCoO2 cathode in electrolyte solutions,as well as in processes of intercalation-deintercalationtion of lithium ions. It has been revealed that the reversible increase and decrease of the resistance of SEI film in charge-discharge processes can be also ascribed to the variation of electronic conductance of active materials of the LiCoO2 cathode.

The objective of this study is to determine the properties of G. amplexifolia. In this paper; the chemical composition, including holocellulose, acid-insoluble lignin, 1% NaOH solubility, benzene-ethanol extractives and ash content, was considered for the variability with respect to positions along bamboo culm height （bottom, middle and top）, parts along radial direction （inner part and outer part）and ages （1-year and 2- year）. The test results were also compared to those of moso that is commonly planted and used in China. This study indicated that both the holocellulosecontent and the lignin content in inner part were lower than ; in outer part, but for extractives and ash content, the reverse was true. Bamboo age also had effect on chemical composition; both the holocellulose content and the ash content in the culm of 1- year were higher than those of 2-year; while the lignin content and the extractive content m the culm of 1- year were higher than those of 2-year. High holocellulose content, low lignin contentand extractive content were advantages of G. amplexifolia.

3rd International Conference on Culture, Education and Economic Development of Modern Society (ICCESE 2019)

作者： Jingfang Chen Suding Fei Jinyin Huang jinmei xu Liqun Wu Ningbo College of Health Sciences

The aim is to evaluate the impact of the flip-up classroom on the initiative and academic achievement of the vocational nursing students. The method of survey is convenient sampling method. A total of 137 high-level nursing students from 4 classes in a higher vocational college were randomly divided into a flipped classroom(test group) and a traditional lecture class(control group). After the intervention, the two groups of nursing students' learning initiative and academic achievement were compared and use the questionnaire survey method and interview method to understand the nursing students' cognition and evaluation of the curriculum flipped classroom. The results show that 60.6% of the students accepted the way of flipped classroom learning. The most worrying was the learning effect and self-time management. The learning group's learning attribution, learning maintenance and academic performance were higher than the traditional lectures, and the difference was statistically significant(P<0.05). It can be concluded that the flipped classroom based on micro-video resources can improve the learning initiative and academic achievement of nursing students to a certain extent. The self-time management ability of nursing students is an important factor to ensure the implementation of the classroom.

In order to explore the feasibility of using X-ray to measure moisture content in the drying process and have a further study on the effect of precision of moisture content when scanning through different grain directions,X-ray scanning method and weighting method were used to measure average moisture content of Cunninghamia lanceolata during hot air *** results show that the moisture content values of two methods were very close to one another,the determination coefficients of both were highly correlated with a value over 0.99,and the absolute deviation was below 2%;when scanning along radial direction and longitudinal direction,the precisions of average moisture content were higher than that of the tangential direction,but the deviation can be negligible in the actual measurement;in the practical application,the effect of grain direction on precision of moisture content measurement could not be taken into account when using X-ray to measure the moisture distribution of wood.

解决中国国家治理现代化研究中存在片面化和碎片化的问题,需要以关系性思维为基础,从主体性关系、客体性关系、过程性关系、效果性关系等基本关系性论题的角度理解和研究国家治理现代化。具体而言,在治理主体日益增多而呈现广泛性的情况下加强党的集中统一领导,以维护党中央权威为处理主体性关系的基本遵循;在治理范围、领域、内容等愈发呈现复杂性和全面性的现实中首先处理好主要矛盾,以解决新时代社会主要矛盾为抓手;在治理过程的互动性、包容性和开放性不断凸显的情况下,坚持以人民为中心的价值标准与实践导向;在多元化治理量化指标的评价性挑战面前,能够做到充分尊重差异性关系,从总体上考量国家治理的现代化水平。
