The studys object is bitch forest .spruce forest ,fir forest, chrysanthemum alp, willow community and two couch grass, so the research of the soil microorganisma,soil enzymatic activity in the subalpine coniferous forests in western Sichuan is significant to china .

因此，开展对川西地域中独特的生态环境中土壤微生物群落、以及与碳氮循环有关的土壤功能微生物数量和酶活性等的分布特征研究，进一步揭示川西亚高山植物群落的生态学过程已成为一项重要的研究课题。

In his mouth were the remains of fir trees--the last meal that he had before he fell into the crevasse and broke his back.

它的嘴里还留有冷杉树的残物--这是它掉入冰窟跌断脊柱之前的最后一餐。

On mountainous sites, grade Ⅰ or Ⅱ stands including land below the crown of the secondary broadleaf forest and the Chinese-fir plantation or east-facing, shady dry land could be considered for the plantation. The transmittance of crown in the areas should be 55%~60%. One-year-old high quality seedlings above 25 cm tall and 0.25 cm in diameter near the ground-level should be used. For high-yield, field cultivation, shading facility should be considered and seedlings of taller than 15 cm and greater than 0.15 cm in diameter near the ground should be applied. The appropriate density and sunlight transmittance ought to be 30 cm×30 cm and 50%, respectively.

结果表明，利用山地种植，选择透光率为55%~60%的Ⅰ、Ⅱ类立地的残次阔叶林和杉木林冠下，或地形隐蔽、东向的山垅旱地，选用苗高25 cm以上、地径0.25 cm以上的1年生优质苗木造林；利用农田进行庇荫设施高产栽培，应选用苗高在15 cm以上、地径0.15 cm以上规格的苗木栽植，适宜栽植密度为30 cm×30 cm，遮阳透光率在50%左右。

各地段土壤抗冲性的垂直空间变化规律，可归纳为草被生长影响型，树木生长影响型和多因子综合影响型三种类型。

The static natural frequencies and dynamic frequencies (under 3000rpm) are calculated by the finite element method and cyclic symmetry technique. The rotating vibration behaviors of the two models are compared. Different vibration characteristics between the two models are discussed. Geometry mismatch in a turbine blade root, which arose in manufacturing process or caused by wearing out during service, leads to contact conditions changed in fir-tree attachments. As a result, shifting of the fundamental frequencies and redistribution of stress in the blade base possibly cause failure of the blade.

在叶片—轮盘耦合系统振动研究方面，建立了带围带的叶片振动计算模型和带围带的叶片—轮盘耦合系统振动计算模型，考虑旋转离心力作用，采用波传播技术，对两种模型分别进行了整圈模态分析，得到了某汽轮机叶片模型和叶片—轮盘耦合模型在0转速和工作转速(3000rpm)下的振动模态，并对所得结果进行分析比较，讨论了整圈叶片振动模态与叶片—轮盘耦合振动模态的区别。
