We propose a hybrid optical bistable device based on a fibre Bragg grating. The experimental set-up is designed by using real communication components. The optical bistable characteristics are simulated. The feedback nonlinearity and the delay time of the device are emphasized. We discuss the potential of such a device in sensor applications.

新《音乐课程标准》明确指出:“音乐教育要以审美为核心,作用于人的情感世界。”而音乐欣赏是一种最直接的审美活动,用音乐本身的力量,使欣赏者置身于音响的天地中,通过教学能有效培养学生感受美、鉴赏美、创造美的能力,促进学生品德、智力、审美力的全面发展,更能体现《标准》中的四个价值,即:审美体验价值、创造性发展价值、社会交往价值、文化传承价值。因此,如何上好音乐欣赏课是摆在每位音乐教师面前的一个重要课题。
数学寓于生活,服务于生活,把所学的知识应用到生活中去,是学习数学的最终目的。正如《数学课程标准》所指出的:“数学是人们生活、劳动和学习必不可少的工具,能够帮助人们处理数据、进行计算、推理和证明……数学在提高人的推理能力、抽象能力、想象力、创造力等方面有着独特的作用。”既然数学对人们有这么多的益处,学生应该是非常乐意去学习数学,急切投入到学数学、用数学、探索数学的无穷乐趣之中去,但事实并非如此。通过
