运动引起的

It has been frequently assumed, but not proved, that the majority of the migrants in what has come to be called the Great Migration came from rural areas and were motivated by two concurrent factors: the collapse of the cotton industry following the boll weevil boll weevil: n.

通常认为，但没有证实，这一被称作大迁徙运动中的多数的移民者来自农村，并且他们被两种共同存在的因素所驱动－开始于1898年的由棉铃虫害导致的棉花工业的垮掉和1914年一战爆发引起的欧洲移民的终止导致的北方对劳力的需求增多。

Because chronic obstructive inflammation of airway severely influences the ventilation and exchange function of COPD patients, The motor ability of patients is limited .Despnoea and fatigue limit patients to sedentary,because of this, skeletal muscle began to analosis,oxygen uptaking capacity of skeletal muscle descends,and concentration of chondriosome degrades.Function limitation of skeletal muscle causes oxygen needs increase,so vicious cycle emerges,and further to restrict patient's respiratory and motor function.

由于气道的慢性炎症性阻塞，严重影响了慢阻肺患者的通气及换气功能，使得患者的运动能力明显受限，因喘息和疲劳而限制了患者的运动能力，使患者出现久坐，由此出现骨骼肌的萎缩，骨骼肌摄氧能力下降，线粒体氧浓度降低，骨骼肌的功能受限又会引起通气量不足，进而引起低氧血症和高碳酸血症，使患者的摄氧需求增加，由此出现恶性循环，进一步制约了患者的呼吸和运动功能。2001年正式提出肺康复作为中重度COPD患者稳定期非药物治疗的首选管理方案。

The results show that the microstructure of ventra1 scale for python was composed of micro-convex and plank structure that was periodically arranged, it was mensurable and could be described by 9 characteristic parameters. Its surface was different in their forward and backward lean angle. The frictional coefficient of the ventra1 scale had closely relationship with moving direction, it decreased with the increasing load. The value of the frictional coefficient was about 0.07. The frictional coefficient while python moved backward and laterally were equal, and that was 33% more than that moved ahead. The frictional force of the ventra1 scale surface was caused by mechanical tooth function of micro-convex, acting intermolecular force and material's elastic hysteresis. The difference of forward and behind bevel for micro-convex was the anisotropy reason of frictional force.

结果表明：腹鳞表面的微观结构由指状微突体和板结构部分周期排列而成，其结构可用9个特征参数定量描述；腹鳞表面摩擦力由分子作用力、表面微突体的犁沟力、楔形作用力以及材料弹性滞后共同引起；腹鳞表面的摩擦系数在0.07左右并与运动方向有关，摩擦系数随载荷增加而减小；后向运动及左、右侧向运动时摩擦系数基本相等，比前向运动时高33%左右；腹鳞表面微突体不同方向上倾斜角度的差异是引起摩擦各向异性的主要原因。

RESULTS :① The left anterior descending branchwas most likely to be damaged;②The specificity between the wall-motion abnormality in A,AS,Apex an d single LAD disease was great (P.05);LAD and left circumflex artery infarcts could lead to AL and I regional wall-motion abnormalities respective l y;contractile function hypokinetic of the single I segment was mostly connected with LCX and right coronary artery injuries;patients with whole left ventricul ar contraction function hypokinetic always suffered from the three-vessel disea se .

结果：①冠状动脉梗塞后左前降支受累最为多见(45%)；②LAD单支病变与前壁、前间隔及心尖部室壁运动异常有关(P.05)。LAD与左回旋支病变，主要为前间隔和下壁运动异常；而单纯的下壁室壁运动异常多为左旋支与右冠状动脉病变引起。3支病变造成心肌运动普遍减低，且以侧壁及前侧壁的室壁运动异常则更为显著(P.05)。

It has been proved by previous studies that peripheral nerve injury can induce a series of changes of expression of some neural active material and their receptors either in the somata or in the terminals of the damaged primary afferent neurons and motoneurons. These changes may reflect a re-ordering of metabolic priorities so that the synthesis of trophic factors or growth-associated proteins augmented while that of neurotransmitter-related proteins decreased.

以往的研究表明，周围神经损伤能够引起受损神经元(包括初级传入神经元和运动神经元)的胞体或终末内某些神经活性物质及其受体的表达发生一系列变化，其中与神经生长和营养有关的物质常发生上调，而与神经传递有关的物质则发生下调；与此同时，受损神经元的周围常伴随发生胶质反应及神经胶质增生等变化。

A related set of problems is raised by the use of man in forming the names of occupational and social roles such as businessman, chairman, spokesman, layman, and freshman, as well as in analogous formationssuch as unsportsmanlike and showmanship.

由于man 的使用所引起的一系列相关问题产生了，在构成职业或社会角色类别的名称，如商人、主席、发言人、外行和渔夫，以及将这个字用于类似的构词法中，如违反运动精神的和善于表演的才能。

The quasi-perpendicular collisionless shock consists of foot, ramp and a series of overshoots and undershoots, after travelling back upstream for a short distance, the reflected protons gyrate back into the downstream where an temperature anisotropy is formed due to an anisotropy of velocity distribution, then excite Alfvén ion cyclotron waves and mirror waves that dissipate the kinetic energy into heat; At quasi-parallel collisionless shocks, the reflected protons can travel far upstream, and lead to the generation of ion beam instabilities which excite large-amplitude right-hand polarized ultralow-frequency resonant waves whose frequencies are are about〓 These waves are convected back downstream by solar wind and gradually merge to form the downstream state, in the meantime new waves are generated continuously in the upstream, this process where ULF waves are generated and merge into downstream state is cyclical.

准垂直无碰撞激波系由根部、斜坡区以及一系列的低冲和过插组成，被激波反射的质子向激波上游运动很短的距离就在回旋作用下再次向下游运动，和激波发生相互作用以后进入激波的下游，在激波的下游引起质子速度分布的各向异性，进而引起激波下游温度的各向异性，激发起Alfvén离子回旋波和镜波，将激波上游的动能耗散成激波下游的热能；在准平行无碰撞激波(θ〓＝10°)情况下，这部分质子能向激波上游运动很大一段距离，并在激波的上游激发起束流不稳定性，引起大振幅的低频波动。

The conversions of ice temperature and ice velocity occur from bridge to trough of terrain on the eastern Nyainqentanglha Range. The ice temperature at bridge is lower. The ice at bridge starts to move due to the larger gravitational driving stress. During the course from bridge to trough of terrain, basal ice temperature rises because of the friction. While reaching the pressure melting point of ice, basal decollement occurs, and higher velocities can still be produced at trough.

而位于念青唐古拉山东部地区的冰川，冰温和冰速从地形脊到地形槽处发生了较大的转化过程，在地形脊处冰温较低，受重力加速度的影响，冰川开始产生滑动，从地形脊到地形槽滑动的过程中，其底部受摩擦加热的影响，底部冰温升高，达到融化点，底部产生变形，到地形槽处仍会产生较大速度的滑动，因此冰川的运动从地形脊到地形槽处发生了转化，即地形脊处的滑动属动力过程引起的滑动，而地形槽处的滑动属热力过程产生的滑动。
