Thus, after the reform, propelled by a series of forces, anewrelationship structure between the grass - roots governments and the country society has gradually emerged, that is, the interacting relationship structure limitedly guided by the township government. this change in grass - roots governments - country society relationship structure indicates that after the reform, although the township governments still have superiorities over against the country society in running of power, arrangement of rural resources, realization of interests, the country society has gain more and more self - developing space, self - owned resources and some self - integrating capability. furthermore, the country society has begun to interact with the township governments in the public spheres
改革后，在一系列動力機制的推動下，基層政權與鄉村社會的關系結構已朝向鄉鎮有限主導的互動關系結構轉變，這一變遷意味著，在改革之後，鄉鎮政權雖仍在與鄉村社會的關系結構中占據主導地位，但鄉村社會逐漸從原有的行政性束縛中解脫出來，擁有了一定的自主空間、自主資源、和自主整合能力並開始與鄉鎮展開了體現著鄉村自主利益的雙向互動。 -
This paper studies the design methods and techniques of the broadband lna. using negative feedback techniques and lossy match method, a broadband lna acceptable for sdr is presented. the measured results showed that over 30mhz ~ 3000mhz, the lna achieved a maximum noise figure of 2. 0db, a power gain of 22db with gain flatness of less than 2. 0db

Based on these advantages we analyze the performance of constant - power variable - rate m - qam schemes for spectrally efficient data transmission over nmf channels. by introducing the adaptive modulation approach, we gain two things : 1 ) the error rate is kept at a constant level. 2 ) the achievable spectral efficiency comes within 5 db of the shannon capacity limit. at the last chapter, the presentation of a single base station and a single mobile scenario proved the feasibility of adaptive schemes
然後作者的精力轉入通道的自適應方案的研究中，首先通過研究發現nakagami衰落因子的適當調整可以近似於常見的瑞利衰落和萊斯衰落，接著研究在無線通道中採用三種不同自適應方案時的通道容量，研究表明速率的調整是增加通道容量的關鍵，在此基礎上，著重研究了離散變速率qam的情況，表明這種調制方案無論在頻帶利用率還是在系統平均誤碼率比其它情況提高很多。 -
Ytterbium ( yb ) - doped silica fibers have a broad - gain bandwidth ( 850 ~ 1050nm ), excellent power conversion efficiency, and a broad - absorption bandwidth ( 900 ~ 1200nm ). their ability to provide amplification over the very broad wavelength range from ~ 975nm to ~ 1200nm is expected to generate increasing interest in the near future. they offer an almost ideal gain medium for the fiber lasers and fiber amplifiers that work at the wavelength around 1 m
