肌紧张的

Pediatric neurologists believe that children like to chew gum Masticator always in "a state of tension."

儿科神经学家认为，喜欢嚼口香糖的孩子咀嚼肌始终处于"一种紧张状态"。

Dominated by the occurrence of masticatory muscle contraction caused by tension.

经支配的咀嚼肌发生紧张收缩所引起。

Results Gene transcripts of key components of RAS were found in the esophageal musculature.

结果 RAS基因转录的主要元件在试管肌组织中被发现，免疫化学方法显示了肌束和血管壁中分离的血管紧张素2-1型受体染色。

In fact they have a problem with inheritable genetic condition called myotonia congenita. That' s why when they are nervous, their muscles become stiff, then they got tripped over and fell down.

事实上，这些羊之所以会这样是因为它们患有遗传性的肌强直症，因此当它们一紧张，肌肉就会僵硬，然后它们就会被绊倒。

In addition, lack of sleep will make your body tense, such a loose state so that a tight orbicular muscle contraction disorders, there twitching eyelids.

此外，睡眠不足会使你的身体紧张，这样一个松散的状态，这样一紧轮匝肌收缩失调，有眼皮跳。

Alpha motor neurons that innervate muscle fibers are located in the ventral horns of the spinal cord, and comprise the efferent limb of this reflex arc.

这是一个单突触反射通路，运动依赖感受器的反馈，间接的Ⅰa传入纤维也在后角与抑制的中间神经元突触，这就能通过依次激活与α运动神经元连接的拮抗肌来抑制主动肌的紧张。

In a voluntary cervical motion, the neuromotor control exercised by the central nervous system determines the time, intensity, and a nature of excitation of agonists and antagonist muscles.

在颈椎主动运动的过程中，由中枢神经所支配的神经运动取决于主动肌和拮抗肌刺激反应的时间和紧张程度。

These compounds inhibit an enzyme called angiotensin--converting enzyme, which is responsible for making the muscle cells in blood vessels contract, which drives blood pressure up.

这些化合物能抑制一种叫血管紧张肽—转化酶的酶，这种酶使血管肌细胞收缩，从而驱使血压上升。

To investigate the the body shape strength and kinematics thateffects sprint expert performance 17 healthy male sprinters weremeasured using SongxiaM9000 high speed vidicon in the field; body shape of sprint athlete were tested by steel rule; Meanwhile shoulder were tested at 60, 240and360 deg/sec velocities ; lower limb were tested at 60, 240 deg/sec velocitues using Biodex-II tesing and rehabilitation system in the laboratory This research provide theoretical basement to scientifically make reasonable exercise prescription and perfect sprint theoryThe result show that (1) The results of correlation indicate that 100M performance related to the shoulder fast flexion torque and hip flexion/extension torque^ ankle fast dorsiflexion torque ;(2) The upper arm relaxing enclose and lower limbs length effect 100Mperformance;(3) The biggest shoulder extension joint, swing rage of shoulder and the biggest elbow joint extension effect 100M performance.

使用松下M9000高速摄像机对100米跑动过程中的运动员进行录像，同时测试短跑运动员100米成绩，利用爱捷录像分析系统获取运动学参数；用人体测量尺测试短跑运动员的肢体围度；同时采用Biodex-Ⅱ型等动测力及康复统，测试运动员上肢肩关节及下肢髋、膝、踝3个关节的等速屈伸肌力。在角速度60°／s、240°／s和360°s下测试肩关节等动向心收缩肌力；在角速度60°／s9慢速和240°／s及120°／s下测试下肢3关节等速向心及离心肌收缩肌力。分析肢体围度、各关节肌肉力量和运动学参数与100 影响河北省二级以上短跑运动员专项成绩的因素。一身体形态、力量素质和运动学参数米成绩的内在联系，为合理制订短跑力量训练和完善短跑理论提供理论依据。结果表明；肩带肌群肌力矩确实与100米成绩呈显著高度相关，同时髓关节屈伸力矩比、踝关节背屈力矩与100米跑成绩呈显著中度相关，可能《是影响100米的因素之一。（2）上臂紧张围、上臂放松围与100米跑成绩呈显。著中度相关；最大肩关节伸角、肩关节摆动幅度和最大肘关节伸角与 100 米成绩呈显著中高度相关。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
