Past investigation found the rock in the right dam foundation composing of granite(γ_4~3～γ_5~1) in dyas- trias,which has a very complicated mechanical environment. The complicated phenomenon is as follows: tectonism, alteration, rock mass demobilize, rock mass stress release and other factors.

前期的调查表明其右岸岩体力学环境复杂，表现为：构成右岸坝基岩体主体的二迭～三迭纪花岗岩(γ_4~3～γ_5~1)受构造变动、蚀变、风化卸荷等因素的影响形成了坝基软弱岩带和坝肩上部卸荷松弛岩体。

Results In 84 cases of nerve root type,stenosis was found in 438 intervertebral foramen,of which C6～7 and C5～6 intervertebral foramen stenosis accounted for 79.6%.The causes of intervertebral foramen stenosis were uncinate process articulation hyperosteogeny,intervenebral disc protrusion,vertebral body hypertrophy,zygapophysis hyperosteogeny and dislocation etc.40 cases of vertbral artery type manifested that vertbral artery became slim and deviousness as a result of the compression of vertbral artery （20.7%） by osteophyte.22 cases of myeloid type manifested with cervical spinal canal stenosis,hyperosteogeny of posterior vertebral body edge,posterior longitudinal ligament calcification and cervical intervertebral disc protrusion etc.

结果 84例神经根型中，发现椎间孔狭窄438处，其中C5～6和C6～7椎间孔狭窄占79.6%，椎间孔狭窄的成因有钩突关节骨质增生、椎间盘突出、椎体肥大、小关节突骨质增生、错位等；40例椎动脉型表现为骨赘压迫椎动脉（52.5%），导致椎动脉变细、粗细不均和椎动脉迂曲。22例脊髓型表现为颈椎椎管狭窄、椎体后缘骨质增生、后纵韧带钙化、椎间隙狭窄和颈椎间盘突出等。

There are nine bivalents in pollen mother cells at late diplotene or early diakinesis, and the homologous chromosomes essentially arrange on the equatorial plate at late metaphase Ⅰor early anaphase Ⅰ, then the two homologous chromosomes of each bivalent separate from each other and move to two opposite poles drawn by spindle fibers.

在减数分裂双线期末或终变期初，可以观察到9个二价体，在中期I末至后期I初，同源染色体基本排列在赤道板上，然后在纺锤丝的牵引下二价体的两条同源染色体分开，分别移向两极，每一极有9条染色体，从而确认该属植物的染色体基数为x=9。

The dynamic rheological behavior and non-isothermal cold crystallization of polywere studied to reflect the disentanglement effect of the pulsatile extrusion flow field.

通过分析 PET 熔体的动态流变参数和结晶动力学过程的变化，间接证实动态挤出聚合物熔体分子的解缠结作用。

The results of experiments indicated that the TLCP phase dispersed well in the PET matrix.

共混物熔体的表观粘度远低于纯PET的粘度，共混物熔体属切力变稀流体，其流动呈假塑性流动。

The results showed that the addition of OMMT was beneficial to improve mechanical properties and flame retardant properties of PP matrix. The molecular chain of PP was effectively inserted into lamellar structure of OMMT. The dispersion of OMMT in PP matrix became worse with the increase of OMMT content.

结果表明：OMMT的加入有助于提高PP基体的力学性能和阻燃性能；熔融插层法可以使PP的大分子链有效地插入OMMT的片层之间；随着OMMT用量的增加，其在PP基体中的分散性变差。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
