现代文明建设不能脱离本民族深厚的文化背景，以科学求实的态度对传统的伦理道德思想进行价值选择，将其中蕴涵的积极、进步、合理成分进行新的转化，使之与当前急剧转型的社会现实相适应，是时代发展的需要，也是构建有中国特色的社会主义道德文明的重要内容。

With the development and progress of the society, autonomous learning and characteristic learning become more and more important in the instructional mode of adult education, and the paper-and-pen exam comes to expose its disadvantage like unilateralism and changelessness. We find out in instructional practice that the paper-and-pencil tests usually hard to fit the cognition of adult learner, so it is hard to evaluate accurately and efficiently.

在实际教学中我们发现，传统的笔试方式往往很难适应成人学生的认知特点和认知规律，从而难以保证考试结果作为课程教学效果测评的准确性和有效性；并且，传统笔试形式极大忽略了考试的诊断反馈功能，忽略了考试结果所体现出的教学过程中出现的问题或是教师很难从考试结果中发现问题，因此不能有针对性地改进教学。

to reduce the impact of carrier frequency offset in ofdm system,this thesis designs a new carrier frequency offset estimation scheme for ofdm system.the carrier frequency offset estimation includes acquisition and tracking.we adopt variable step size adaptive algorithm.the acquisition range of the proposed algorithm is as large as one half of the overall signal bandwidth.through this method we can not only avoid the feedback by using forward error correction,but also reduce the times of complex multiplication in order to reduce the power consumption of the system.this algorithm not only has low complexity and fast convergence nut also can improve the demodulation performance of ofdm system.computer simulation illustrates the superior performance of the proposed algorithm with regard to estimation accuracy in both awgn channel and multi—path channel.

摘 要：为了减小正交频分复用系统受频率偏差的影响，在ofdm系统中设计了一种新的载波频偏估计算法。频偏估计包括跟踪和捕获两个阶段，文中采用变步长自适应算法来进行跟踪，这个跟踪算法的捕捉范围是整个信号带宽的一半。通过此方法，不但可以利用前向纠错的方式来避免反馈，而且可以缩减复数乘法的次数以降低计算复杂度和系统功耗。该方法运算复杂度低，并具有较好的收敛性，能改善odfm的解调性能。从计算机的仿真效果可以看出无论是在awgn信道上还是在多径信道上都表现出了卓越的性能。

By using correlation analysis, we are able to calculate the self correlation coefficient of the same characteristic value to achieve the association of current and previous one and the cross correlation coefficient of two different characteristic values, consequently achieve the data association between characteristic values. 3. On the characteristic level, we are trying to fuse the characteristic values from different data source and identify the exact type of the fault.

用同种类多个传感器进行测量，得到的数据以加权自适应估计方法将它们融合处理得出最佳值；对来自异类多个传感器的数据进行最小二乘估计处理将它们融合到一起，完成数据关联和从测量数据估计出它们所反映的特性；通过计算征兆数据的自相关系数能完成同一征兆当前值与过去值的关联，又可以通过计算两个征兆数据的互相关系数完成这两个征兆的关联。

In the aspect of Opto—electrical signal processing, because the heterodyne interference signal is a high frequency fringe signal, how to measure the phases change of this signal——including the integer part of phases change over 2π and decimal part of phases change within 2π, is a difficult problem in electrical circuit technique.

一方面，该电路能同时测量出相位改变量的2π整数部分和2π以内的小数部分，从而实现了大量程和高精度的统一；另一方面，由于该电路是模拟电路，其最高工作频率可以远大于由数字集成电路组成的条纹计数电路，故在实际应用中，其工作频率的设计范围能够适应较宽的外差干涉差频范围，这就为高速激光外差干涉测量打下了基础。
