Based on this, a new WENO difference scheme which based on Dispersion-Relation-Preserving relation is developed, and representative test cases with this scheme for computational aeroacoustics problems has been implemented and compared in order to test capability of wave capturing; In addition, WENO schemes generally do not converge at high order in the presence of contact discontinuity of Euler equations, so a conservative front tracking technique coupling WENO schemes and Level Set method to simulate the translating density profile is presented here, and numerical simulation with this technique for representative test case has been implemented and results show the desired accuracy.

Online learning must be the main stream and online test will substitute the traditional paper-and-pencil test in the future. In order to respond to the coming of online learning era, how to make good use of the Internet is an important issue. Teachers can design online test questions to effectively understand students' learning performance and control their learning condition. Then teachers can provide remedial programs. Therefore, developing a flawless online test system to satisfy users' request is a critical issue both in practical and academicals.

网路学习必然是未来发展趋势，线上测验也逐渐取代传统考卷测验方式成为主流，为因应网路教学时代来临，如何善用网际网路让教师得以藉由线上测验之试题设计，而能更有效进行测验与验收学生之学习成效，且充份掌握学生之学习情况，后续即能针对能力较弱之处进行补救教学，因此，建构完善的线上测验系统以符合使用者需求，对实务界及学术界来说，都是一项很值得进行研究之议题。

Another work of this paper is to study the continuous design of Test Automation. Common aspects of continuous design include the performance and maintainability of test automation system itself, the independence of test execution, and the analyzability of test result. This paper gives the concrete resolution of above four aspects, and also proposes other aspects need to be considered in continuous design, such as extendibility in future and capability to multi-product and multi-edition.
