强直

Results Sacroiliac joints in 62 cases were abnormal:in early stage,articular face was affected and the bone cortex incrassated and osteosclerosis partly,joint space was normal;in late stage,vermiform destruction of bone was seen in articular face,the density of cortex was heighten irregular,joint space widen or narrow,and at last the joint space vanished,the joint ankylosed.

结果 62例患者骶髂关节表现异常，包括：早期，骨关节面受侵蚀、骨皮质局限增厚、硬化，关节间隙正常；后期，关节面呈虫蚀状改变，关节面皮质密度不规则增高，关节间隙增宽或变窄，最终关节间隙消失，关节强直。

Headache, vomiting, ataxia, and visual deterioration are common presenting symptoms. Hemiataxia is a frequent finding in adults because of the hemispheric location of most tumors. Gait ataxia, papilledema, nystagmus, facial palsy, and neck stiffness are also common.

头痛、呕吐、共济失调以及视力减退是常见的临床表现，成人常出现偏身共济失调，这是由于肿块多位于小脑半球，步态共济失调、视乳头水肿、面瘫、颈项强直也是常见的。

Of the extremities only; causes spastic deformity of the hand or foot.

肢体末端的肌肉强直；导致手或脚的痉挛。

Ankylosing spondylitis: what is the cost to society, and can it be reduced?

强直：带来的社会成本是什么，有办法降低吗？

PD's mainly symptoms include stilly shacking , bradykinesia , rigidity muscles and abnormal posture and pace .

其主要临床症状有静止性震颤，运动迟缓，肌强直和姿势步态异常等。

Giving two equal-intense stimuli which is higher than the threshold stimulus and whose intervals are longer than the single twich period, two independent contracting curve can be observed. Giving two equal-intense stimuli which is higher than the threshold stimulus and whose intervals are longer than the refractory period, an additive-contracting curve can be observed. Giving several equal-intense stimuli which is higher than the threshold stimulus, tetanus curve can be observed.

当给予两个等强度的阈上刺激，且刺激的间隔大于单收缩的时程，在计算机中可以观察到两个独立的收缩曲线；当给予两个等强度的阈上刺激，且刺激的间隔小于单收缩的时程而大于不应期，在计算机中可以观察到两个收缩曲线的叠加，称为收缩的总和；当给予若干个等强度的阈上刺激，在计算机中就可以观察到强直收缩曲线。

You do remember an inhuman tenseness of muscle and nerves.

你能想起来只是超出人体承受的肌肉强直、神经紧绷。

When this is the case, the evaluation of the muscular response to a continuous tetanic stimulation may be useful.

在这种情况下，评估肌肉对持续强直刺激的反应性可能有用。

So the recovery rate after moderate fatigue was related to the tetanic contraction duration.

3在5 000 ms内给予300 ms的刺激(DC为6.0%)，持续5 min，强直收缩张力降低约50% P0(L50P)，转入恢复期(图1)。

Becuase tetanic stimulation less than 1 second can produce logn-term increase of efficacy of the synaptic transmission, LTP has been considered as the possible physiological substrate of learning and memory.

由于不到一秒钟的强直刺激就能引起突触传递效能长时增强，故LTP已被认为是记忆的生理学之可能基础。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
