The experiment results indicate that V-system is an effective tool used to reconstruct complicated geometric information with both continuous and discontinuous signals. This is the essential difference among V-system, the classical complete orthogonal system with continuous functions and Walsh and Haar system which include intense discontinuous functions.

利用三角域上V-系统进行三维复杂几何模型的重构实验，实验结果表明，V-系统对复杂的、连续间断并存的几何信息重构特别有效，这与经典的连续正交函数系及强间断的Walsh及Haar函数系有本质的不同。

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。

Because the information in groupware system has Characteristic of complex, various, large quantity, non-structure or structure complex, close relativity of information, etc, and the traditional relational database can hardly handle these complex and various information. This paper aims at the problems that groupware system meets in application, put forward the research on groupware system based on object-oriented database management system.

由于群件系统中所处理的信息具有复杂、多样、量大、非结构化或结构复杂以及信息间的相关性紧密等特征，而传统的关系型数据库很难处理这些复杂多样的信息，因此，本文针对群件系统对数据库的应用需求，提出了基于面向对象数据库管理系统的群件系统的研究。

This text thinks, toing make the local government come out the predicament that system set up, shoulding emphasize from three commence namely:The local government should implement to produce the power working talent ownly, setting up with the system the diversification that promote produce the power, and pass to produce the power protect, resolving the motive of the tiny view corpus encourage the problem;To systemize the stipulation norm is central and creative relation in local system;Withdraw the market working talent realm, realize the type of 范 that system set up convert, such as reasonable boundary that contracts public economic market front, clear and definite government working talent with relax control etc..

本文认为，要使地方政府走出制度创新的困境，应着重从三个方面入手，即：地方政府应履行自己的产权职能，以制度创新促进产权的多元化，并通过产权保护，解决微观主体的动力激励问题；以制度化约束规范中央与地方的制度创新关系；退出市场职能领域，实现制度创新的范式转换，如收缩公有经济的市场战线、明确政府职能的合理边界和放松管制等。
