Longgang nature reserve plays an important role in preserving two langur species of both white - headed langur and francois langur. interview and field survey methods were used to survey the distribution and population size of these two langurs in this natural reserve from december 2001 to january 2002. the result indicated that the reserve has 8 groups of white - headed langur with 68 individuals in longrui and 10 groups of francois langur with 75 individuals in longgang. the distribution area and population size of both of the two langurs in this reserve have greatly declined in the past decades. they are seriously threatened and have high risk of disappearance from this reserve if no effective measures are to be taken at once
為了確定弄崗自然保護區內白頭葉猴的種群數量,彌補黑葉猴種群數量的空白,掌握此保護區葉猴的生存現狀,採用訪問法和實地數量統計法相結合的方法對弄崗自然保護區的弄崗、隴瑞和弄呼3個部分進行深入的調查研究.調查結果表明,在隴瑞片范圍內,共有8群白頭葉猴,種群大小在68隻左右,和20世紀80年代末的244隻相比,數量下降相當驚人;在弄崗片內,共記錄到黑葉猴群10群,最大的種群為11隻個體,最小的種群是4隻個體,共計約有75隻黑葉猴(絕對數量統計) ;弄呼的黑葉猴種群已經于上個世紀的晚期消失.造成目前狀況的因素主要是過度狩獵和其他形式的過度干擾.弄崗自然保護區的葉猴種群數量已經接近可持續繁殖種群的最低水平,如不採取有效的保護措施,這個種群將很可能在短期內消失2 % 22 % and 29 % respectively less than using other three knives at cutting speed of 500mm / min when the moisture contents of rootstalks was 48. 2 %. the cutting forces were tested at four different parts of rootstalk that were the middle part along a radius, the tip part along a radius, the middle part along axis and the stalk part along a radius, and the force at the middle along a radius is the largest and increase 32 % 45 % 111 %, respectively more than at the other three parts. the force increase 37 % to cut the rootstalks from the areas one crop a year more than that from two crops a year
試驗結果表明,根茬含水率愈高,剪切力愈小,根茬含水率與剪切力近似為二次曲線關系;刀片剪切速度愈快,剪切力愈小;凸曲線、斜線、凹曲線和直線四種不同的刀刃曲線對整株根茬剪切力依此由小到大,凸曲線和斜線剪切時有一定程度的滑切作用,所以剪切力相比較小,當根茬含水率為48 . 2 ,剪切速度500mm min時,與其他三種曲線相比凸曲線型刀刃的剪切力依次分別減少了7 . 2 、 22和29 ;對根茬中部、梢部和根部的剪切力,在相同試驗條件下,徑向中部最大,比梢部,軸向根部和根部莖稈所需剪切力分別增加32 、 45和111 ;當含水率為48 . 2 ,刀片的剪切速度為500mm min時,一年一熟玉米根茬比一年兩熟的玉米根茬剪切力增大37 。In chapter one, we propose a new mixed method called characteristics mixed finite element method for a convection - dominated diffusion problems with small parameter e : we handle the convection part whth backward difference scheme along the characteristics, obtain much smaller time - trunction errors and avoid numerical dispersion on the front of the peak curve of the flow : we use a lowest order mixed finite element method to deal with the diffusion part, so this scheme can approximate the unknow function and its following vector with high accuracy at the same time
第一章中我們對小參數對流占優擴散問題提出了新的數值方法? ?特徵混合有限元方法,即對方程的對流部分採用沿特徵線的後退差分格式求解,以保證較小的截斷誤差限並避免了在流動的鋒線前沿數值彌散現象的出現;對流動的擴散部分採用最低次混合元方法求解,以保證格式對未知函數及伴隨向量的同時高精度逼近。由於該方法中檢驗函數可取分片常數,此格式在某種意義上具有局部守恆性質。Baltimore - astronomers reacted with jubilation wednesday at new pictures of mars taken by the hubble space telescope, saying the planet ' s close pass to earth enabled the hubble to capture " quite spectacular " images
