Methods(1)4 cities were chosen randomly according to their economic status and geographical location.(2)An autorefractor was used to detect the diopter in the preschool children from 20 kindergartens randomly selected from each of the 4 cities.(3)1%atropine ointment was applied to the c onjunctival sac of the children with suspect myopia for 3 days and the refractio n of light in their retina was then examined by a barred beam skiascope.(4)The eye axis and corneal curvature of the myopic children were measured.(5)The diop ter,eye axis,and corneal curvature were examined every 6 months during 1-year f ollow-up after the diopter was properly rectified.

(1)依经济状况和地理位置按随机原则抽取4市县；(2)从4市县中各随机选择20间幼儿园，对所抽取的在园学龄前儿童用自动屈光仪进行屈光筛查；(3)可疑近视患者予以1%阿托品眼膏涂双眼3d，由专人用带状检影镜进行视网膜检影验光；(4)确诊为近视的患者自愿进行角膜曲率和眼轴测量；(5)近视患者经适当的屈光矫正后，按要求进行为期1年的前瞻性随访，每半年进行1次屈光状态、角膜曲率和眼轴的检测。

Methods One hundred and six eyes of 56 patients were divided into three groups: mild myopia (-0.50~-3.00 D), moderate myopia (-3.25~-6.00 D) and high myopia (-6.25 D~) based on measurement with autorefractor in cycloplegia and uncycloplegia.

对56例行屈光不正矫正术的患者（106只眼）分别用电脑验光（睫状肌麻痹和非睫状肌麻痹下）、显然验光、Zywave波前像差仪法测量眼屈光不正，并将患者按屈光不正度数分为三组：低度近视组(-0.50~-3.00 D)，中度近视组(-3.25~-6.00 D)，高度近视组(-6.25 D~)。

The 3D motion informationincluding ante-flexion,back-stretch,nearside bending,and starboard bending of the human cervical spine were measured for unstable,fixed,and fatigue loading states.

采用该方法分别对保存良好的人体颈椎标本在失稳、内固定以及疲劳3种状态下的三维运动情况(包括前屈、后伸、左侧弯、右侧弯4种运动)进行了测量，并以每种运动情况下的颈椎C 1-C 2节相互旋转角度衡量其内固定的效果。

The 3D motion information （including ante-flexion, back-stretch, nearside bending, and starboard bending） of the human cervical spine were measured for unstable, fixed, and fatigue loading states.

No significant difference were found between left and right hand weight loading for erector spinae during the trunk movements, but the values of AEMG with back weight loading were significantly higher than left and right hand weight loading;(2)The AEMG of lumbar multifidus had no significantly different under three load ways during the walking.

(1) 躯干屈曲伸展过程中，腰部多裂肌与竖脊肌各自两侧的激活程度呈现对称性特点；躯干伸展运动对腰部竖脊肌和多裂肌的激活程度大于屈曲运动；(2)腰部多裂肌在躯干旋转时激活特征存在显著的对侧增强效应；(3)腰部前屈过程中，竖脊肌和多裂肌肌肉的高激活区域可能集中在45°—65°的角度范围之内。

In the later stages of pregnancy, extreme forward bends are contraindicated

另外，针对怀孕后期的准妈妈们，过度的前屈也是不适当的。

A pulled hamstring is a common muscle strain seen in yoga class. This occurs particularly where the hamstring attaches to the sitting bones, and is a result of overstretching in seated forward-bending poses.

腘绳肌的拉伤是瑜伽中的常见损伤，尤其发生在腘绳肌与坐骨联结处，也可由于坐立前屈体式中的过度拉伸。

The pupil diameter of different diopters changes greatly under different rays, and it is a very important parameter to measure the pupil diameter in different diopter under different rays before the refractive surgery.

不同屈光度在不同光线下瞳孔直径有很大的变化；不同屈光度在不同光线下的瞳孔直径是屈光手术前评估的一个重要参数。

The findings indicate that the training method of trunk flexors and trunk extensors combined trunk rotators is more effective in stroke patients.

依据脑卒中患者躯干肌力低下的特点，选择性地强化对部分躯干肌的训练，即在加强前屈和后伸肌群训练的同时，增加躯干旋转肌群的训练，可以更加有效地提高对脑卒中患者平衡功能障碍的训练效果。

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。
