The disturbance which seemed to be a normal academic controversy virtually opened up a fact that there lied a variance in harmony between the KMT and the Communist Party after the Wannan Event and also, to tell the culture bifurcation and conflict at the mid-upper period of the anti war.

这场风波表面上是一场普通的学术争论，实质上却是无意间表露了皖南事变后国共两党间的貌合神离，以及思想文化界在抗战中后期的分歧与冲突。

The existence of outer power stayed in Arab world destroys union of geography, society, economy, culture and spirits of Arab world, separates the connection of different regions, obstacles development of Arab unity movement which is thought to be outer factors. However, deeper reasons should be found in inner world. Inner reasons include that political structure of Arab world and deeply dispute weakens the base of Pan-Arabism movement. In local region, the thoughts of Religious Minorities and Sectarianism deny and destroy Arab nationalism movement and its premise-the sincerity of country. Some non-Arab nations pursuit the unity of theirs own not the whole Arab nations. Regional Nationalism and Islamism obstacle the development of Pan-Arab unity movement Weak sovereignty of Arab countries and diverse political rules weaken the political base of movement of Pan-Arab unity. Unbalance of economy, culture and base of society between different regions also lag the unified movement.

内因包括：阿拉伯世界的政治结构和王朝间的利益纷争削弱了泛阿拉伯统一运动的群众基础和民族基础；在局部地区，宗教少数派及其宗派主义思想不断地否定和破坏阿拉伯民族主义运动及其前提——对祖国的忠诚；阿拉伯世界中一些非阿拉伯民族的独立诉求挑战地区的统一；地区民族主义和伊斯兰主义阻碍了泛阿拉伯统一运动的开展；孱弱的国家主权限制了阿拉伯国家在民族事务上的能动性，而多样的政治体制则削弱了泛阿拉伯统一的政治建构基础；阿拉伯各地区或国家间经济、文化和社会发展的不平衡以及整体上的滞后削弱了泛阿拉伯统一运动的经济、文化和社会基础，等等。

The paper investigates both block-type pilot linear minimum mean square error algorithm and IEEE802.16 OFDM channel estimation analysis. Simulation results confirm the block-type pilot structure is more suitable for IEEE802.16 system. An optimal pilot setting algorithm, based on space frequency domain, is explored and the pilot chart is presented. The proposed algorithm finds its application in MIMO-OFDM. Simulation results show the algorithm presents a good approximation to the perfect channel state information curve, with about 2dB difference in SNR. The simulation results also demonstrate the algorithm achieves fairly high stability in the environment of fast fading, performance of the proposed algorithm is better that of pilot training channel estimation.3. Taking into account the characteristics of IEEE802.16 OFDM system, OFDM system simulation platform is constructed in Matlab, exploiting simulink as a tool. OFDM modulation and demodulation simulation system are configured on LabVIEW platform. All the system signal processing is simulated, including defining system parameters, designing modulation model, and verifying all the proposed algorithms under different environments, such as white Gaussian noise, multi-path fading, with or without guard interval etc. Bit error performance is evaluated. The research provides valid theoretical basis for practical OFDM system performance evaluation.4. Taking advantage of software radio, the paper designs a hardware platform with both 256-IFFT/FFT and 512-IFFT/FFT OFDM schemes co-existing in one platform. You can predetermine one from the two schemes to carry out almost the same model function with different system performance and parameter setting.5. Referring to IEEE802.16 standard, the paper proposes a design method for generating signals and frames suitable for laboratory investigations implemented in laboratory environment.6. Based on 6701evm digital evaluation card, combined with analogy front-end, the paper designs a DSP software model to deal with baseband signal processing. An overall OFDM scheme, with modulation and demodulation function, is accomplished.

这就意味着，儒家思想在不断适应现实、从而不断被&再定义&和&再解读&中，常常会发生这样一种逻辑和语义上的转换：它本来是要说&只有具备了某些根据和条件，君权才是应该服从的&，而实际表达的却是&只要是成功登上皇位者，其统治权就是应该服从的&，从而实现了对君权合法性的间接建构。

The article presents the developing condition of PWM and SVPWM first.Then the theory of SVPWM is discussed in detail.The SVPWM is based on the thought of magnetic chain tracking.It makes the ideal magnetic chain circle of three-phased sysmmetry electric motor supplied by three-phased sysmmetry sine wave voltage for basis,uses the practical magnetic chain vector formed by the different switch modes of three-phased inverter to track the basic magnetic chain circle.During the course of tracking,the inverter changes the switch modes properly to form the PWM waves.Then the modulation wave of SVPWM is analyzed in detail.The modulation wave of SVPWM is implicit,but the analogous modulation wave in A-B-C axis needs to be calculated in order to expose the internal relation of SVPWM and SPWM.That is to show the implicit modulation wave of SVPWM. SVPWM actually is a transformed SPWM ruly sampled by the modulation wave which is injected by the zero prefaces based on space vectors.

本文首先对脉宽调制技术的发展现状进行了综述，在此基础上分析了电压空间矢量脉宽调制技术的发展现状；接着对空间电压矢量脉宽调制技术的基本原理进行了详细的分析和推导，SVPWM是基于磁链追踪的思想，它以三相对称正弦波电压供电下三相对称电动机定子理想磁链圆为基准，由三相逆变器不同开关模式下所形成的实际磁链矢量来追踪基准磁链圆的，在追踪的过程中，逆变器的开关模式作适当的切换，从而形成PWM波；然后详细分析了电压空间矢量脉宽调制技术的调制波，虽然SVPWM法的调制波是隐含的，但是为了揭示SVPWM法与SPWM法的内在联系，需要求出SVPWM在A-B-C坐标系上的等效调制波，也就是将SVPWM的隐含调制波显化；SVPWM实质是一种基于空间矢量在三相正弦波中注入了零序分量的调制波进行规则采样的一种变形SPWM。
