Development with making use of the file information resources is guide and guarantee of archieves work.This article mainly discusses the problem existing in the process of developing the archives information resources and promotes some methods to solute the problems.
At present,the sales of new energy vehicles grows slowly in China.In view of this phenomenon,this paper carries out the investigation of new energy automobile consumption behavior influence factor,and applies SPSS to make factor analysis.The results shows that the main factors affecting the new energy automobile consumption behavior can be classified as preferential policies,related costs,facilities,safety and comfort,vehicle function,propaganda and reputation,convenient service seven factors.Finally,this paper puts forward some specific proposals for the development of new energy vehicles.
In order to overcome the problems of time-consuming and high energy consumption in traditional green space planning optimisation methods, a new energy-saving optimisation method based on artificial bee colony algorithm is proposed. The energy-saving model of urban green space planning is established by energy plus software, and the influence of various variables on energy consumption of urban green space planning is analysed by combining the parameter operation algorithm in genpot optimisation software. Based on the artificial bee colony optimisation algorithm, the optimisation parameters are selected, the optimisation objective function is established to optimise the parameters, and the energy-saving method of urban green space planning is studied. The experimental results show that the proposed method has high optimisation efficiency, and the energy consumption of the optimised model is greatly reduced.
Key Laboratory is an important carrier of research and innovation in colleges and universities. In their construction,management and development process,laboratory culture has an important leading role. During laboratory construction process,laboratory culture,as an abstract concept,often lets the teachers and students and technology managers feel no focus. This article elaborates the meaning,content and implementation of college key laboratory cultural construction and manages to make colleges laboratory culture with a more clear ideas and goals,in order to provide reference for the majority of research managers.
An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.
The power communication system provides powerful technical support for realizing the intelligent operation and information management of the power grid and improving the operation efficiency and power supply quality of the power grid. Quantum key distribution (QKD) is considered one of the most promising technologies for commercialization. QKD uses a single photon to encrypt data to produce a more secure and reliable password. This paper intends to study the hierarchical, centralized control architecture of power dispatching based on quantum essential supply (QKD). The performance indexes of MDI-QKD under symmetric and asymmetric conditions were studied by local optimization. The optimal key formation rate of the algorithm is analyzed. From the perspective of quantum critical utilization, a quantum key utilization scheme for grid backbone dispatching service is proposed. The dynamic adjustment test of multi-node time slot and service key update rate is carried out. Experiments show that the MDI scheme can effectively improve the effectiveness of a multi-node QKD system. Thus, the security of data transmission of the core business of power dispatching data networks can be ensured to the greatest extent. AMDI can effectively reduce the transmission timeout of low-priority data streams because the delay of high-priority data streams reaches the proportion. It can be an excellent solution to the power system and the password requirements.
Noni (Morinda citrifolia L.) is widely used as a health food and medicine because it is rich in polysaccharides, polyphenols, and flavonoids; it is precisely because noni is rich in these substances that people usually like to soak it in liquor to drink.This study sought to maximize the main active constituents ( polysaccharides, polyphenols, and flavonoid s) dissolved in liquor and spirits soaked with noni fruit, using ethanol as the solvent to optimize the extraction conditions using response surface methodology.The highest polysaccharide yield of 16.35% was found at 60°C for 3.5 h, a liquid-solid ratio of 52 mL/g, and an ethanol concentration of 25%.The optimal extraction conditions for polyphenols were 75°C for 1.5 h, a liquid-solid ratio of 90 mL/g, and an ethanol concentration of 50%, resulting in a 10.37% yield.The optimum extraction conditions for flavonoids were 75°C for 1 h, a liquid-solid ratio of 70 mL/g, and an ethanol concentration of 100%, with 1.35% yield.Many active ingredients, including polysaccharides, polyphenols, and flavonoids, were obtained via alcohol extraction of noni fruit, suggesting that liquor and spirits soaked with noni fruit are novel and promising types.This study provides a technical reference for the production of high-quality noni liquor.It is recommended to use the best conditions for the extract of polysaccharides, polyphenols, and flavonoids, and blending them to obtain the desired degree of alcohol.
It is very important for health management of resident to establishing community resident health file,the thesis mainly discuss improving resident health aware、 strengthen doctor training and establishing unity information platform and so on,so as to enhance establishing and management of community resident health file aiming at emerging some problem in the course of establishing community resident health file for Qinghai province.
