布達拉宮海拔3700多米，佔地總面積36萬余平方米，建築總面積13萬余平方米，主樓高117米，共13層，其中宮殿靈塔殿佛殿經堂僧舍庭院等一應俱全，是當今世上海拔最高規模最大的宮堡式建築群。At an elevation of more than 3, 700m, the potala occupies an area of more than 360, 000m. its 13 - story main portion rises 117m. the whole complex, consisting of halls, stupa - tomb halls ( where the relics of the supreme lamas are preserved ), shrines, prayer rooms, monks dormitories and courtyards, is recognized as the world s highest and largest castle palace
布達拉宮海拔3700多米，佔地總面積36萬余平方米，建築總面積13萬余平方米，主樓高117米，共13層，其中宮殿、靈塔殿、佛殿、經堂、僧舍、庭院等一應俱全，是當今世上海拔最高、規模最大的宮堡式建築群。The others showed partly decreased, but the degradation of vegetation were obviously in lower reaches of tarim and cherchen river ; in the mountain area of southern xingjian, the forest area were increased, and the others decreased ; in northern xingjian, both the mountain and the plain area increased. they showed the decrease of desert and the increase of oasis ; the change of vegetation cover in the hexi corridor - alax desert were not obviously ; but in chai - damu basin, the area of desert and low cover grassland increased, the others vegetation decreased, especially in the high cover grassland. that showed the great degradation of ecosystem, and the most of degradation was shown in the north hillside of the arjin mountain and qi - lian mountain
而從各個分區來看，情況不盡相同:南疆地區平原區綠洲面積擴大，荒漠面積基本不變，其他類植被面積不同程度縮小，而在塔里木河下游、車爾臣河下游植被退化;南疆山地森林面積略有增加，其他類植被面積略有縮小;北疆的平原區和山區的植被狀況均有改善，表現為荒漠面積縮小，綠洲面積增加;河西走廊一阿拉善地區總體變化不大;但是柴達木盆地的荒漠面積、低覆蓋度草地增加，其他類植被，尤其是甚高覆蓋度植被（草甸）的面積縮小，表明該地區的生態環境退化，而退化表現的主要地區在環柴達木盆地的阿爾金山和祁連山的北坡。Secondly, basing on the theory of on - off gain of small signal, the raman gain coefficient for frequency shift between 0. 5 and 20 thz of standard sigle mode optical fiber is measured by pump - probe method through a super luminescent diode ( sld ) as a broadband small signal probe source. thirdly, numerical simulation analysis of gain characteristic of raman fiber amplifier for c band wdm signal light is made according to the raman gain coefficient of the fiber measured before through target and four rank runge - kutta method. at the invariability of wavelength and maximum power of each of two pumps, schematic of powers of two pumps for best flatness on c band wdm optical gain was found out, at the same time, the factors of resulting in gain saturation is analyzed, too
本文首先應用經典的電磁理論對拉曼光纖放大器的工作機制進行了分析，然後，根據小信號理論推導出的開關增益求出了光纖拉曼增益系數的表達式，採用泵浦-探測波的方法，利用超輻射激光二極體（ superluminescentdiode簡稱sld ）作為探測光源，測量了所用標準單模光纖頻移為0 . 5 - 20thz的拉曼增益系數，之後根據所測得的光纖的拉曼增益系數譜對應用該類光纖構成的放大c波段wdm光信號的拉曼光纖放大器的增益特性採用打靶法和四階龍格- - -庫塔進行了數值計算，在給定了兩個泵浦光源的波長和最大功率后，找出了反向泵浦情況下使c波段wdm光源增益最平坦的兩個泵浦的各自最佳功率，同時也分析了導致信號光飽和的原因。分享友人
