Abstract］ Objective To investigate the relation of pterygium and ametropia.

目的 研究翼状胬肉与屈光不正的关系。方法随机对196例（200眼）翼状胬肉病人应用日本产Topcon KR-8100型全自动电脑验光仪进行术前、术后验光。

Methods IOL Master and ultrasound biometry were performed in 154 eyes to measure AL and ACD. SRK II, Haigis, Holladay, Hoffer Q and SRK-T formulas were used for IOLs power calculation. 3 months after surgery, patients were checked their refractive error.

121例（154眼）老年性白内障，术前分别应用IOL Master和眼科传统设备两种方法测量眼部参数并计算所需人工晶状体的屈光度，术后检查术眼屈光误差。

Their MP including muscle of hypothenar, first interosseus and flexor carpi ...

测定前，由同一操作医师测定患者相应的MP(小指展肌、第一骨间肌和尺侧腕屈肌)。

Flower pull the basic moves, because is located in the mountains, high mountain坡陡, gradeability would move the high leg lift, body lean, downhill is restrained out of state knees, body slightly Yang, thus men dance to "play to跋, knee should be bent, step to stability,"women dance to" into to bow, back to D, feet outside the charge-off."

拉花的基本动作，因地处山区，山高坡陡，爬坡则要迈步高抬腿，身体前倾，下坡则是双膝出于拘谨状态，身体稍仰，因而男性舞步为"起要跋，膝要屈，踩要稳"，女性舞步为"进要弓，退要丁，脚外撇"。

The Colles fracture was stable with the fixation according to its merits.

当腕关节轻度掌屈、稍尺偏，前臂旋前位时，骨折断面的掌、背侧中点所受应力分别为压应力和张应力，但数值较小。

The visual acuity, dioptometry and corneal topography were investigated in a 12-month follow-up study.results the postoperative visual acuity of the 56 eyes(84.8%)was equal to or above the best corrected visual acuity before lasik.conclusion lasik for ametropia after cataract extraction and intraocular lens implantation is an effective and safe surgery.but the indication must be selected appropriately.

观察视力、屈光状态、角膜地形图情况。结果 56眼（84.8%）lasik术后视力均达到或超过术前的最佳矫正视力，10眼（15.2%）lasik术后最佳矫正视力下降1～2行。结论 lasik是矫治白内障摘除人工晶体植入术后屈光不正的安全、有效的方法。

Results:Four-years-old children with normal vision got myopia when they were nine years old.All those with emmetropia before six years old gr...

检查学龄前儿童视力，可以预测以后的屈光改变，学龄前儿童视力越好，越应提前预防近视。

Methods: Add different power spherical lenses on 32 volunteers with normal binocular function to induce simple myopia(+1D,+2D,+3D),simple hypermetropia(-1D,-2D,-3D) and anisometropia.Assess the visual acuity,stereocontrast sensitivity and Worth 4 dots fusional function after inducing the anisometropia.

对双眼视功能正常的大学生志愿者32人采用在单眼前加不同度数正负球镜的方法，诱导单纯近视性(+1D，+2D，+3D)及单纯远视性(-1D，-2D，-3D)屈光参差，测定诱导屈光参差后的视力、立体视敏度及Worth四点融像功能。

Abstract］ Objective To evaluate the detection rate, accuracy and factors influencing the measurement of axial length in cataractous eyes using the IOL Master version 5.0 with a composite signal analysis system.

在白内障超声乳化吸除联合人工晶状体植入术中，术前准确测量眼轴长度并计算植入的人工晶状体度数是非常关键的步骤，目前，术后的屈光误差主要来自于由术前眼轴测量误差引起的人工晶状体度数偏差[1-2]。

The electromyographies were made on 12 healthy young adult males to investigate the function of supinators and pronators in the extended and flexed elbows during pro- nation and supination.

本文在12个健康男性青年的旋前方肌、旋前圆肌、旋后肌、肱二头肌及肱桡肌，以Ediswan脑电墨水描记仪，用肌内电极引出电位进行分析，结果认为：旋前方肌无论在肘的伸位或屈位，当前臂慢旋前时，它的电位都比旋前圆肌更活动。

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。
