在讨论中

Wang Xiaoyi discussed the impacts of persistent drought on local livelihood and whether current measures to coop with drought worked well for the long term perspective in his paper. Based on a case case study in Horqin Sandy Land, he suggested that the poverty has been more serious because of drought, it increased the production cost for rich herders, but broken the vulnerable balance in poor households; the uneven distribution of resource in household brought more social problems in the community; the wrong means to cope with drought, which focused on property and ecological compensation, would intensify the poverty problem in pastoralist.

王晓毅在文章中通过兴安盟一个嘎查的实地调查，讨论了持续的干旱对牧民生计的影响及从长期效果来看，现在应对干旱的手段是否可行的问题，文章认为持续干旱正在造成牧区的普遍贫困化，增加了大牧户的成本，但却打破了小牧户的脆弱平衡；在畜牧业收入占主导地位的情况下，资源占有的不均衡导致了更严重的社会问题；在干旱的条件下，试图通过草原产权制度的改革和补偿性的生态政策经常会在运行过程中导致生态的进一步恶化。

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.

QUITE GOOD就相当于分数A,B只是AVERAGE,"OK","C"则是差,这点Cahill自己在他的评论中都写到了: I might add, finally, that my experience with the British academic grading system as an outside reader for Hong Kong University several years ago made me conscious that your gradings are stricter than ours; a student here would be quite unhappy with a B or 13grade in a seminar, but maybe the same isn't true there.

&我最后想要说，我在几年前做过香港大学的校外分数重估专家，这个与英式学术计分系统的经历让我感到你们的计分法要比我们的严格，在这里严格学术会对一个B和一个讨论课的13 级分数很不满，但是这在你们那里也许不是这样。&同时Cahill 自己已经在他的意见书中承认了他已经了解了有关这个分数和论文的背景，，并且还多次着重指出&From the viewpoint of the instructor…&根据以这个课程的指导教师的观点。。。
