Motor unit firing rate is one of the important mechanisms to generate smooth muscle force output. This paper discusses the detection of firing rate from surface electromyographic signals, instead of the invasive needle EMG. The multichannel design is adopted to observe the spatial distribution of EMG firing pattern.

肌肉运动单元活化频率是人体运动控制中枢调节肌肉力量输出的主要机制之一，本文主要是研究从表面肌电讯号分析活化频率之特性，并以多频道记录的方式，分析肢体动作时活化频率在空间之分布模式。

Muscle soreness and the recoery of muscle function in the leg flexors and extensors were not different in C and P groups. Furthermore, although plasma concentrations of interleukin-6 and malondialdehyde increased following exercise, there was no difference between C and P groups.

两组间大腿屈肌和伸肌的肌肉酸痛程度和肌肉作功能力没有差异，此外，尽管运动后血浆IL-6 浓度和丙醛提高，但两组间仍然没有显著性差异。

When the finger is slightly raised, it is possible to alternate contractions between the flexors and extensors, and the slightly raised fingers can receive any added throwing motion by the hand and arm that accelerates their speed by the vertical adjusting motions much more effectively than the motion of a finger touching the key.

当手指稍微举起，屈肌和伸肌有可能交替收缩而且稍微举起的手指可以接受任何附加的下投动作，因为手和手臂促进了它们的垂直调节运动，使手触键变得更加有效了。

By using local intoxication of soman (pinacolyl methylphospho-nofluoridate) the processes of regeneration of AChE activity at motor end-plates and of recovery of neuro-muscular transmission of rat diaphragm were observed. An ameliorative effect of HI-6 on these processes was also observed.

用大鼠的在体膈肌局部索曼中毒法，观察了乙酞胆碱酯酶在运动终板的再生和肌接头传递功能的恢复过程，以及肪类药物(HI-6)对两过程的促进作用。

After the functional appliance protruded the mandible, it resulted in a clear alteration in the biomechanical characteristics of the masticatory muscles. The contractile tension of lateral pterygoiod muscles incerased with its contraction time prolonges, while that of the digsstic muscle decreased and shortened.

当功能性矫治器引导下颌前伸后，对运动下颌肌肉作在体等长主动收缩性质的检测，结果表明翼外肌收缩张力增强，收缩速度变慢；二腹肌前腹收缩张力减弱，收缩速度加快。

All the indexes were tested in 2 -. 4 .. 6 weeks of operative intervals respectively. Results:(1) The general observation in the experimental group ,such as spirit, hair, body weight and activity ,was superior to that in the control group.(2) The recovery rate of sciatic nerve functional index (SF1) was statistically significantly higher in the experimental group than in the control group .(3) electrophysciological indexes: m the experimental group ,the tardy rate of induced motorius action potential ,recovery rates of the amplitude of compound muscle action potential and twitch tension and tetanic tension of triceps surae muscle ,were significantly higher than in the control group.(4) Compared with the control group ,the triceps surae muscle wet weight was significantly greater in the experimental group.(5) histomorphological indexes: the count of myelinated nerve fibers ,diameter of regenerated axon, thickness of nerve myelin sheath and area of capillary were much more in the experimental group than in the control group.(6) observation of ultrastructure with the transmission election microscope: more abundant organell a and maturer myelin sheath lay in the injured peripheral nerve of the experimental group, while not lay in the control group.

分别在木后第2、4、6周时进行各项指标的检测，结果发现：（1）实验组SD大鼠在整个实验过程中，其精神、毛发、体重，运动灵活性等一般情况优于对照组；（2）实验组的坐骨神经功能指数恢复率显著优于对照组，P＜0.01；（3）神经电生理指标：实验组运动神经诱发电位潜伏期的延迟率显著优于对照组，P＜0.05；复合肌肉动作电位振幅的恢复率显著高于对照组，两组比较第2周时P＜0.01，第4、6周时，P＜0.05；小腿三头肌单收缩力和强直收缩力的恢复率实验组显著高于对照组，P＜0.01；（4）小腿三头肌湿重的恢复率，第2、4周时实验组高于对照组，差异非常显著，P＜0.01；第6周时，差异仍显著，P＜0.05；（5）组织形态学指标：有髓种经轴突计数、再生轴突直径的恢复率，毛细血管面积，实验组均显著大于对照组，P＜0.01、P＜0.05、P＜0.001；实验组髓鞘厚度的恢复率也显著高于对照组，第2周时P＜0.01，第4、6周时，P＜0.05；（6）透射电镜超微结构观察：实验组再生轴突中细胞器丰富，髓鞘结构成熟，神经再生情况优于对照纽。

Some of you may think that direct bicep workout is not necessary because other compound exercises have actually worked on our biceps.

你们有些人可能认为，直接二头肌训练没有必要，因为其他的复合运动，其实在我们的二头肌工作。

Either way, the seams of the shirt should lie on the curve of your deltoids (those are the muscles right behind your shoulders—the ones you'd work if you did push-ups).

或者，T恤的省/缝应该取决于三角肌的曲线三角肌在背部正后面，就是做跗卧撑时运动的肌肉

BACKGROUND: Sprint sports requires the balance in the upper limb, pectoral girdle muscle group and lower limb extensor muscle group, and the balance of these muscle strength is a key content to raise the sprinters' performance.

背景：短跑运动中重视上肢及肩带肌群及下肢屈伸肌群力量的平衡，对提高短跑速度起到一定作用。

Objective To discuss the morphology and relative location of cranium,jaw,face,te eth-alveolus which affecting three types of smile,so as to provide a quantitative guideline for the clinical dynamic investigation,diagnosis,treatment planning,prognosis and appraisal i n the practice of orthodontics,orth ognathia and prosthetics.

微笑过程涉及面肌、口唇肌及鼻、唇、颏的解剖形态变化，并与口腔、颌骨及牙－牙槽形态、位置密不可分，是上述相关软硬组织协调运动的结果，而微笑方式的改善亦是预测、评价正畸、正颌外科及修复治疗效果的重要方法。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
