A commutation error is then considered in addition to the conventional residual error to generate the innovative residual error. Such an error is applied into cost functions to derive finite impulse response and infinite impulse response filter-based adaptive algorithms for ANC applications, referred to as FxRLS/CE and FuRLS/FRE+CE algorithms, respectively. Convergence analyses based on Lyapunov stability criteria for time-varying discrete-time systems can be carried out for the FxLMS/CE, FxRLS/CE and FuRLS/ FRE+CE algorithms to ensure stability. Computer simulations and experiments demonstrate that the innovative residual error-based adaptive algorithms can free the restriction of the slow-adaptation assumption in the conventional ANC approaches.
本文中也定义一交换误差并且加入到传统残留误差行形成新残留误差来改善适应性演算法的收敛速度,使用新残留误差推导出了有限脉冲响应滤波器与无限脉冲响应滤波器之适应演算法的新适应性演算法分别为: FxLMS/CE、 FxRLS/CE 和 FuRLS/FRE+CE 演算法,并且以离散时间的 Lyapunov 稳定性准则来证明演算法的收敛性,电脑模拟与实验也显示新演算法免除以往滤波器的参数必须缓慢更新的条件。

Textbook is not only the primary basis for students to grasp knowledge and method but also resort and carrier to train capability. New textbook has been tested in some provinces and cities since 1997, some educational and teaching concepts in new textbook inosculates with new mathematics course which is being tested now, it has taken great role for the transition of teachers' teaching idea and students' learning way. This paper will analyze Plane Analytic Geometry high school textbook of 2004 edition which is published by People's Education Publishing House in some aspects such as content structure, educational function, psychological characteristic according with student cognizance and teaching through the method of content analysis, investigation, comparison and statistical analysis . The paper's purpose is to excavate the potential value of the textbook and understand educational idea and concept of new textbook so that students can grasp more basic thought of analytic geometry in teaching and can learn studying and discovering and solving problem ,at the same time it builds a kind of independent, disquisitive, cooperative and lifelong learning pattern.
教材既是学生掌握知识和方法的主要依据,又是培养学生能力的凭借和载体,自1997年新教材在部分省市实验以来,新教材中所体现的一些教育教学理念与现在正在实验的高中数学新课程相吻合,对教师的教学观念和学生的学习方式的转变都起到了很大的作用,本文将对人民教育出版社2004版普通高中教材中的平面解析几何部分通过内容分析法、调查研究、比较研究、统计分析等研究方法从教材的内容结构、教育功能、符合学生认知心理特点、教学等几个方面进行分析,目的是挖掘教材内容的潜在价值,真正领会新教材所蕴涵的教育思想和理念,以使教师在教学中能够让学生更多的掌握解析几何的基本思想,以培养学生学会学习、学会发现问题和解决问题,为学生构建一种自主的、探究的、合作的、终身的学习模式。

The system of nano-structured assembly and molecular assembly is a new field, which is originated from intercrossing and derivatives of physics, chemistry, biology and material science in nanometer scale. It has not only brought the new opportunity to synthesis of new materials, but also opened the new dimension for physical and chemical investigation. The most importance is that it will be the basis of nano-structured device in the future.
