With normal vision were studied. The result showed: 504 eyes (77. 54%) suffered from hyperopia, 66 (10.15%) from myopia, 2(0.31%)from astigmatism and 78(12. 00%) were emmetropia. Among 325 youths, 172 (52.92%) had esophoria (including esophoria-hy- perphoria), 126 (38.7%)exophoria (including exophoria-hyperphoria), 13(4.00%) hyperphoria and 14(4.31%)had orthophoria.

结果显示，远视者为504眼(77.54％)，近视者66眼(10.15％)，混合散光者2眼(0.31％)，正视者78眼(12.00％)，325人中，内隐斜者为126人(38.77％)，上隐斜者13人(4.00％)，正位者14名人(4.31％)；经用行x列表的x~2检验法分析，屈光不正的类型与斜视的种类之间没有显著联系。

Effects of gravity on pressure distribution and extreme value changed with different postures and IODP.

There was a high risk of thin cement mantle in Gruen zones 1,2 and 5 in the anteriorposterior plane and in Gruen zones 8,9 and 12 in the lateral plane.Typical areas of radiolucency were identified in Gruen zones 2～5 and 10～12 in the middledistal of the stem.Voids appeared in Gruen zones 3～5 and 10～12 in the distal of the stem.

结果(1)按Barrack标准，骨水泥质量A级87.1%，B级11.8%，C级1.1%，无D级骨水泥；(2)按Gruen分区，骨水泥鞘厚度 mm区域多见于正位片上1、2、5区和侧位片上8、9、12区；透亮带多位于假体中远端的2～5区和10～12区；气泡影出现在假体远端的3～5区和10～12区。

There was a high risk of thin cement mantle in Gruen zones 1,2 and 5 in the anterior-posterior plane and in Gruen zones 8,9 and 12 in the lateral plane. Typical areas of radiolucency were identified in Gruen zones 25 and 1012 in the middle-distal of the stem. Voids appeared in Gruen zones 35 and 1012 in the distal of the stem.

结果］(1)按Barrack标准，骨水泥质量A级87.1%，B级11.8%，C级1.1%，无D级骨水泥；(2)按Gruen分区，骨水泥鞘厚度＜2mm区域多见于正位片上1、2、5区和侧位片上8、9、12区；透亮带多位于假体中远端的2~5区和10~12区；气泡影出现在假体远端的3~5区和10~12区。

Fig. 9 Anteroposterior plain radiograph of a right knee, showing posttraumatic ossification known as the Pellegrini-Stieda syndrome.

图9右膝正位片显示创伤后异位骨化，即所谓的Pellegrini-Stieda综合征。

Microcalorimetric measurements of NH~3 adsorption on catalysts reveal that the remarkable strong acidity and catalytic activity of the Al- promoted catalysts are caused by a change of distribution of acid site strengths and an enhancement in the number of strong and intermediate-strong acid sites effective for the n-butane isomerization and benzoylation of toluene.

NH~3吸附微量热结果表明，Al促进样品的强酸性和催化活性的显著提高是由于样品表面的酸位强度分布发生了变化，有利于正丁烷异构化反应和苯甲酰化反应的中强酸位和强酸位的酸量显著增加。

To measure the changes of latera and posteroanterior cephalometric analysis and the changes of casts, before and after treatment with rapid maxillary expansion.

应用RME治疗，测量扩弓前后及治疗结束后头颅定位正位片、侧位片及模型测量方面的变化。

The statistic analysis of the relationship between the operative amounts and the corrected amount of eye primary position of 177 operations on the horizontal recti showed a positive proportional relation. And the correction effect in degree for each mm of surgery is between 1. 2°～2. 2°, and for different types of strabismus and different surgical treatments, the correction effects for each mm of surgery are different.

对临床177例眼水平直肌手术的手术量与眼位矫正量的关系进行了统计分析，结果表明水平直肌的手术量与眼位矫正量有较好的正相关关系，大约每毫米手术量对应的手术矫正量在〓之间，不同类型的斜视、不同的手术，每毫米手术量对眼位的矫正量不同。

How many 2003-digit positive integers have the property that except for the first two di gits

求具以下性质的 2003 位正整数的数目：除首两位数字外，其余所有数字均等於之前两

The primary clinical outcome of this study was functional improvement assessed with the Harris hip score. Serial anteroposterior and lateral radiograms of the pelvis were taken at 3, 6, 12, 18, and 24 months post-operatively to analyze the process of osteonecrosis.

临床评估采用Harris评分系统，评估术后患髋功能的改善情况；影像学评估主要是于术后3，6，12，18及24个月摄取正位及侧位X线平片，观察股骨头修复及有无坏死进展。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
