Bieti lost its habitat continuously in recently decades associated with the extension of rangelands and farmlands, as well as firewood collection etc. The monkey live mainly in primary fir forest and the mixed conifer forest, to evaluate the status of the monkeys' habitat, we employed GIS and RS software to identify the habitat types with five Landsat TM/ETM+ satellite imagery in winter of 1986, 1992, 1997, 2001 and 2006 years respectively. The work resulted in: 1 the size of summer grazing lands, farmlands, and fir forest was 13 100 hm2, 6 400 hm2, and 30 500 hm2 in 2006 respectively; 2 during the past 20 years (1986-2006), the size of fir forest (including primary fir forest and the mixed conifer forest) decreased by 14.6%(5 200 hm2), summer grazing lands and farmlands increased by 47.2%(4 200 hm2) and 14.3％(800 hm2) respectively; and 3, during the past 20 years, the number of firry forest patches increased by 68.4%, the mean size of firry forest patches decreased by 49.3%(from 15.1 to7.6 hm2), the largest patch index of firry forest decreased 54.9%; the patch richness had no change, but the Shannon's diversity index and the Shannon's evenness index increased by 2.7% respectively.

为了评估该物种的栖息地现状和变化情况，我们通过野外调查工作，应用GIS和RS技术，分别解译了1986年、1992年、1997年、2001年和2006年的Landsat TM/ETM+冬季卫星影像，并对解译结果进行了计算和分析，得到了以下西藏种群栖息地的主要结果：1）现有暗针叶林（包括原始针叶林和针阔混交林）面积是30 500 hm2，夏季牧场面积是13 100 hm2，农田面积是6 400 hm2；2）在过去20年间（1986-2006年），暗针叶林面积减少了14.6％（5 200 hm2），夏季牧场面积增加了47.2％（4 200 hm2），农田面积增加了14.3％（800 hm2）；3）在过去20年间，暗针叶林的斑块数量增加了68.4％，平均斑块面积下降了49.3％（从1986年的15.1 hm2下降到2006年的7.6 hm2），最大的斑块指数下降了54.9％；景观丰富度并没有变化，但Shannon多样性指数和Shannon均匀度指数分别增加了2.7％。

Furthermore, the very significant/nearly identical increase in the ratio of doubling times in dmdm medium in the presence/absence of high concentration of paromomycin was observed in symptomatic or asymptomatic cybrid cell lines carrying the c1494t mutation as compared with the average rate in control cell lines.

结果 来自听力下降者的融合细胞系的线粒体dna标记速率分别比对照组4名成员的12个融合细胞系下降了38％和43％，这一缺陷显然造成了携带c1494t突变的融合细胞（不论来自听力正常者还是来自听力下降者）的细胞总体呼吸率下降，或苹果酸/谷氨酸、琥珀酸/3-磷酸甘油及tmpd/抗坏血酸所始动的呼吸率下降。

The results showed compared with the native state the shear strength of rockmass under the saturation state decreased by 11.17%, cohesion force decreased by 16.09%, internal frictional angle decreased by 10.02%.(3) 3D-σFEM numerical simulation software is used to simulate the slope stability on the native state and saturation state. Compared with the nature state the displacement of the discontinuity and stress concentration in the saturation state is largened clearly, the results showed slope stability under the rainfall is weakened.

更多含有天然结构面的岩体试件进行了不同含水量下的强度试验，试验结果证明在岩体试件处于饱水状态时的结构面抗剪强度比天然状态下平均下降了11.17%、粘聚力平均下降了16.09%、内摩擦角平均下降了10.02%；(3)采用3D-σ有限元数值软件对K86+180～K86+470段岩质边坡进行了三维有限元数值模拟，并且分天然状态分阶段开挖和饱水状态分阶段开挖两种不同状况进行了稳定性分析，从分析结果可以看出与天然状态相比，饱水状态下软弱层水平方向位移明显增大，坡脚及软弱层特别是软弱层临空面附近的剪应力值显著增大，并且其安全系数与天然状态相比也显著减小，说明在有大的降雨发生当岩体处于饱水状态时边坡整体稳定性被削弱，边坡失稳可能性增大。
