A parallel and time-based task division method is introduced and the multi-task software architecture is built in the software system for electronic unit pump （EUP） system. The V-model software development process is used to control algorithm of each task. The simulation results of the hardware-in-the-loop simulation system （HILSS） and the engine experimental results show that the OS is an efficient real-time kernel, and can meet the real-time demands of EUP system; The built multi-task software system is real-time, determinate and reliable. V-model development is a good development process of control algorithms for EUP system, the control precision of control system can be ensured, and the development cycle and cost are also decreased.展开更多

Based on this theory, Chinese students in the United States are studied from three perspectives： linguistically, culturally, and social psychologically. It indicated that, to help Chinese students develop their English performance and cultural appreciation in this diverse world, the profession of English teaching in China should cover a variety of domains, including linguistic, cultural and psychological input. Both American and Chinese education can benefit from this special group of Chinese students if they can be better understood, and used as a bridge between China and U. S. cultural and academic exchange. In the meantime, the mirror held up to the Chinese students in these perspectives reflects not only who they are but also who they can become.展开更多
