摘要: According to the requirements, the design principles of web-based learning platform were presented, taking into account teaching and learning. Many instances were introduced to the instructional design. Modular structure was applied to design the system whose model was proposed. The prototype was built by Adobe Flash Professional, a timeline-based, object-oriented authoring tool. User interactivity, loading multimedia files and switching full-screen were achieved by Scripting languages. The result shows that it is informative, user-friendly and suitable for browsing on Internet.

摘要: As a rising practical teaching method, virtual experiment is playing an increasingly prominent role in modern teaching. The virtual experiment for lift coefficient mensuration, which is one of a series of virtual experiment software that have been accomplished based on numerical simulation and modern computer technologies by the authors, was taken as an example, the design principles, modules constitution, developing tools, and experiment courses were introduced. It is of practical significance on how to make use of virtual experiment technology to reform practical teaching and enhance energy efficiency ratio of experimental teaching.

摘要: The pulse wave is a very useful physiological signal which can reveal the information of human organs. D-peak change is an important change of pulse. To study the spectrum of the D-peak changed pulse wave quantitatively and get the statistics result of such kind of change, a new algorithm was proposed and a kind of processing software was designed and implemented. The software was tested by more than 200 person-times PPG pulse waves and showed good performance.

摘要: The laser tracking system is widely used in the large-scale measurement field in industry providing accurate spatial information of measured objects. In this paper, the frame of software system for the laser tracker is introduced, as well as the design and implementation of each module. With the help of the software, customers can attain high precision measuring results within large volume. Functions of information communication, command control, error calibration and compensation, geometric element analysis and display can also be realized. The software system is divided into six modules, including the interconnect communication and on-line control module, error calibration and compensation module, data analysis module, database management module, 3D display of geometrical elements and man-machine interface. The design and construction of each module is described in detail which can help customers realize different functions throughout the measuring process.

摘要: This paper presents the software implementation of a feedback control for the two axes of an XY table and the simulations of motor X and motor y velocity responses to the specific step inputs. The object of the software is to guide the “tool point” around the outside edge of a planar “workpiece” under computer control. PWM method and P control philosophy are used in the control. By means of least-squares estimation, the values of coefficients in the discrete modes for the controlled motors are determined. The results show that the control strategy is practical and the simulations are valid.

摘要: The excessive ammonia nitrogen ions and nitrate in the domestic water and industrial water have seriously detriment of health of human being. The application of optimization solution for water purification is a main method to analyze the function of water purification device. In this paper, an automatic mixing system is designed to analyze the performance of ion-exchange column using LabVIEW. This system can solve the problem such as discontinuous proportion, complicated operation and low proportion precision which exists in the current proportion device. The accuracy of over 97% is shown by the experimental results in this study and it is also found that the quality of water can satisfy the requirement of drinking water.
