不疲劳

"Supraspinatus tendinopathy is a specific diagnosis needs an MRI scan to demonstrate high signal intensity in the tendon without a frank tendon tear," lead author Justin Alan Paoloni, MBBS, PhD, from the Orthopaedic Research Institute at the University of New South Wales in Sydney, Australia, told Medscape in an email interview."It is a common problem, especially in overhead athletes (pitchers, tennis players, and swimmers) and workers, and is thought to be due to a combination of specific anatomical factors (subacromial impingement, anterior glenohumeral instability, often coexisting with tendinopathy) and relative overuse (repetitive shoulder motions, fatigue)."

澳洲University of New South Wales的医师Justin Alan Paloni表示，岗上肌肌腱炎在没有明显肌腱破裂的情况下，需要使用MRI的高密度讯号扫描，作特定的诊断才可以发现；这对某些族群的人而言是个普遍的现象，尤其是需要作手部举高动作的运动员，如棒球投手、网球运动员、游泳者及从事绘画、机器修复的人员；这个病征是许多症状的组合，如下滑囊伤害、前肱肩胛骨不稳定等，都会引发随著肌腱病变；此外，过度的肩膀运动及疲劳也是原因。

Some evidence indicates that the combination of extrinsic, intrinsic and genetic factors all play a role to cause the disc degeneration, with a progressive decrease in proteoglycan content leading to dehydration of the nucleus pulposus, and Type Ⅰ collagen begins to appear in the matrix, the ratio between Type Ⅰ and Type Ⅱ increases. All these cause the swelling pressure, disc height and the disc load bearing ability decrease. The disc progressively herniate and cause radiculopathy and myelopathy.

内因、外因及遗传方面的诸多因素导致椎间盘逐步退变后，其实质就是基质中蛋白多糖的减少，含水量降低，Ⅰ型胶原出现在基质中，Ⅰ、Ⅱ型胶原的比例明显上升，髓核呈纤维样改变，导致椎间盘的膨胀压降低，承重能力下降，椎间高度降低，椎间盘承受的重力不能平均地向各方向传递，致使纤维环疲劳、破裂、髓核突出，造成脊髓或马尾神经受压，引起严重后果。

Easy if you are the spirit of excitement, mental fatigue, anxiety, and hypochondriacal phenomena would have to consider is not suffering from a nervous breakdown.

答：容易，如果你是精神兴奋，精神疲劳，焦虑，疑病现象将要考虑的是不是从精神崩溃的痛苦。

During the process of fracture toughness test of 7150 alloy extrusion,the prior fatigue crack initiated and propagated inhomogeneously.

在准备7150合金平面应变断裂韧性试样的过程中，预制疲劳裂纹发生不均匀扩展。

The excessive amplitude of vibration may also jeopard driving and pedestrian so as to make them not comfortable and safe. Therefore, to solve the problem about buffeting of bridge is concerned by people engaged in bridge engineering.

虽说抖振一般不会引起桥梁的整体破坏，但如果处理不好，也会使桥梁局部某些构件产生疲劳破坏，而且过大的抖振振幅也会危及行车和行人的舒适与安全。

Although buffeting may not cause the bridge destroyed in whole, it can induce the fatigue for structure elements if it is not carefully dealt with. The excessive amplitude of vibration may also jeopard driving and pedestrian so as to make them not comfortable and safe.

Airline cabins are commonly pressurized to altitudes of 1,524 to 2,438 meters, or about 5,000 to 8,000 feet, above sea level. Healthy people have no problem at such altitudes, but those with underlying heart or respiratory disease who may already have low levels of oxygen in their blood can develop symptoms of mountain sickness — fatigue, headache , lightheadedness and nausea.

客机飞行在海拔1524米到2438米，或者5000至8000英尺的高空时，航班客舱里只是一般性的加压，健康的人在这样的高度不会有问题，但是那些心脏衰弱或者有呼吸疾病的人——他们的血液里氧气水平低——会引起山峰病的症状，如疲劳、头痛、头晕和恶心。

Customer: It has been several months. At first, I do not know it was a kind of disease, I thought it was because of pressure and weakness, but it is too uncomfortable. I cannot sleep, and always wake up in the middle of the night, sweating, agitated, tired, and itchy. I also feel lumbaginous. After checked, I knew it is Menopause Syndrome.

顾客：得有几个月了，我原来不知道是这种病，我还以为是压力太大，身体比较虚弱的原因呢，可是后来太难受了，天天睡不好觉，常常是半夜醒来，浑身大汗，爱烦躁，爱发怒，特别容易疲劳，而且，总觉得成群的蚂蚁在皮肤上、头发里爬来爬去，还感觉腰酸背痛的，这不，一查才知道是更年期综合征。

A DISEASE that carries with it a social stigma causes additional and unnecessary suffering. This has often been so with myalgic encephalomyelitis, or chronic-fatigue syndrome, as it is also known.

如果说哪种疾病会带来附加的社会污名和不必要的痛苦，那一定是肌痛性脑脊髓炎了，它另一个响当当的名头是慢性疲劳综合症。

For 42CrMoA steel of shear failure type, the study show that Fatemi's model and socie's shear model based on critical plane method correlate with fatigue life well, but predictions are nonconservative.

对于剪切型破坏的42CrMoA钢，研究表明，以临界面法为基础的Fatemi模型和Socie的剪切型模型对疲劳寿命拟合较好，但仍偏于不安全一侧。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
