查询词典 real ability and learning

At first, with the low-frequency data measured, three of the LRE fault detection systems for the real-time condition are proposed using the nonlinear identification technology of the BP neural network, the state estimation technology of the dynamic neural network, and the pattern recognition technology of the fuzzy hypersphere neural network. The learning algorithms of the BP and dynamic neural network are researched at the same time. Furthermore, while the engine operation is divided into the start and steady-state processes, the real time ability, the response time, the accuracy, the robustness, the sensitivity and the monitoring parameter optimization are studied. In the test data analyses of the YF-75 engine, the detection system correctly carried out for all normal tests, and in the three abnormal tests the engine faults were accurately forecasted.

首先，基于低频测量数据，采用BP神经网络的非线性辨识技术、动态神经网络的状态估计技术及模糊超球神经网络的模式识别技术，提出了三种发动机故障实时检测系统；同时研究了BP神经网络和动态神经网络的学习算法；另外还把发动机工作分为启动过程和稳态过程，分别讨论了神经网络故障检测系统的实时性、及时性、准确性、鲁棒性、敏感性及参数优化问题；在YF-75发动机试车数据分析中，不仅全部正确地监测了正常试车过程，而且准确地预报了三次异常试车中的发动机故障。

The real-time learning ability and the fast convergence of the recurrent network model of nonlinear dynamical system have been obtained by introducing the forgetting factor in the objective function and the maximum likelihood estimation principle.

本算法在目标函数中引入了遗忘因子，并借助于非线性系统的最大似然估计原理成功地解决了动态非线性系统回归神经网络模型权系数学习的实时性和快速性问题。

How to improve self-controlling ability?The research findings show that it is especially important for students to enhance their subjective consciousness, and to have a right math idea, and to have opportunities of experiencing the real math activity process, and to master methods of math thinking, and improve the communication among members in"math learning community". It is the point of break-through to train students to have the consciousness and skills of self-testing, if we want to improve students'self-controlling ability.

本论文的研究结果显示，培养中学生的自主意识、使学生树立正确的数学观念、让他们有机会经历数学活动的真实过程、掌握数学思想方法、加强"数学学习共同体"成员间的相互交流是培养中学生数学学科自我监控能力的关键，培养学生对数学学习过程的自我检验意识和技能是培养中学生数学学科自我监控能力的突破口。

Constructivism advocates "a student-centeredlearning under the guidance of teachers". They agues that knowledge is not taught bythe teachers, but is acquired in a certain situation, that is, in the social and culturalbackground, through the Construction of Meanings by using the necessary materialsfor study, with the help by others (including teachers and learning partners). Theystress to create a variety of real language environments for the students, and pay muchattention to training the students actual ability of using the language. Its theory hasgreat inspiring and guiding significance in organizing teaching and compilingteaching materials.

建构主义提倡&教师指导下的，以学生为中心的学习&，认为知识不是通过教师传授得到的，而是学生在一定的情境即社会文化背景下，借助其他人的帮助，利用必要的学习资料，通过意义建构的方式获得的，强调为学生创设真实多样的语言环境，重视培养学实际运用语言的能力，其理论对组织教学、编写教材富有启发和指导意义。
