At present, the college English testing system has become an indispensable system in many universities. However, the English test system is not highly humanized due to problems such as unreasonable framework structure. This paper combines data mining technology to build a college English test framework. The college English test system software based on data mining mainly realizes the computer program to automatically generate test papers, set the test time to automatically judge the test takers’ test results, and give out results on the spot. The test takers log in to complete the test through the test system software. The examination system software solves the functions of printing test papers, arranging invigilation classrooms, invigilating teachers, invigilating process, collecting test papers, scoring and analyzing test papers in traditional examinations. Finally, this paper analyzes the performance of this paper through experimental research. The research results show that the system constructed in this paper has certain practical effects.

Si/Al/C composites were synthesized by the method of doping aluminum and glucose-modified. The samples were characterized by XRD, SEM, and the capacity and cycling stability of the composites were tested by electrochemical charge/discharge test system. After glucose was pyrolyzed, the first discharge and charge capacity of Si/Al/C composites were 1312 and 956.7mAh/g, and the first coulombic efficiency was 72.9%. After 50 cycles, the capacity of Si/Al/C composites was 440mAh /g and the coulombic efficiency remained over 98.1%

And Performance

Significant progress has been made recently in solar parabolic trough technology development and deployment. Part of this success is due to the changing world energy scenario and the recognition that viable renewable energy technologies can play a role in supplying world energy needs. Part is also due to ongoing collaborative efforts by industry and the Department of Energy’s (DOE) Concentrating Solar Power Program (CSP) to enhance the state of the technology in terms of both cost and performance. Currently, there are two trough concentrator projects which the DOE CSP program is supporting. One company, Solargenix, is developing a design to be used in a 64MW plant outside of Boulder City, Nevada. This design is based on the original LUZ LS-2 trough concentrators employed at the Solar Electric Generating Systems (SEGS) plants in Southern California. Another company, Industrial Solar Technology (IST), is working on a scale-up of their design used historically for process heat applications. Very different from the LS-2 approach, this design is still in the research and development stages. One way in which the DOE CSP parabolic trough program assists industry is by providing optical testing and qualification of their concentrator designs. This paper describes the Video Scanning Hartmann Optical Test System (VSHOT) used to optically test both of these designs. The paper also presents the results of tests performed in the past year and what impact the testing has had on the developmental direction of each design.

The effect of various concentrations of lithium sulfate on human erythrocytes in vitro has been studied. It has been shown that the effect of lithium salt in maximum pharmacological and toxic concentrations on cells leads to a modification of the physicochemical state of membrane-bound proteins and lipids. It was found that in human erythrocytes exposed to lithium ions, there is a decrease in the activity of membrane-bound acetylcholinesterase and methgemoglobin reductase, as well as a change in the microviscosity of the lipid bilayer of membranes. The results obtained can be used to create a cell test system for assessing the toxicity of lithium compounds.
