Results There was strong correlation betneen ambeyopia and property of focus, other factors such as myopia, hypermetropia, and anisometropia didn′t have relation with degree of amblyopia until its affected the property of focus.

结果 弱视轻重程度最相关的因子是注视性质，而远视、近视程度、屈光参差程度及有无斜视与弱视相关程度被剔除，提示这些因素只有影响到注视性质时对弱视程度的影响才有差异。

In this paper, the propagation and focus properties for several modes describing hollow beam are analyzed, and the focus properties for hollow gaussian mode are particularly discussed. Furthermore, a new mode, high-order Bessel-Gauss mode, is put forward to describe hollow beams. The results for high order Bessel-Gauss beams propagating through lens focusing system and free space are derived by terms of Collins integral formula.

本文分析了几种描述空心光束数学模型的传输特性和聚焦特性，着重讨论了描述非中空光束的数学模型的聚焦特性；同时提出了一种描述完全中空的空心光束的新模型――高阶贝赛耳高斯模型，并且运用Collins积分公式，分析了这种新模型的空心光束的传输特性和聚焦特性。

R4The working principle of convergence reflection type photo switch is similar to that of direct reflection type one, while its projector and light receiver focus on object distance, only when the object presents to the focus can the photo switch actuate.

R3 会聚型反射式convergence reflection type 会聚型反射式的光电开关的工作原理类似于直接反射式光电开关，然而其投光器与受光器聚焦于物距离，只有当物体出现在聚焦时，光电开关才有动作。

In patients with CPS but without GTS, the focus was mostly located in unilateral temporal lobe, esp, in the medial temporal lobe or the limbic system if the ictal and the interictal EEG was normal, but in those patients with CPS and GTS, the focus was located in the lateral temporal parietal lobe or temporal parietal-occipital areas.

CPS不继发全身性发作的患者，病灶多局限于一侧颞叶，如发作期和发作间期脑电图均正常，更应考虑病灶位于颞叶内侧面，或边缘系统；CPS继发GS的患者病灶多位于颞叶外侧面与顶、枕交界区。

Results 20 cases of CT examination had made proper diagnoses,the CT imaging finding about the most of peripheral cholangiocarcinoma included:There was the atactic low density tumour in liver,its borderline was unclear,enhanced scan appearances were irregular peripheral enhancement,centripetal enhancement,and delaying enhancement;There was concretion and dilatation of bile buct in or around the focus;The local envelope of liver was lacunose and the local liver was atrophied,There was abroad putrescence and liquescence in the focus.

结果 20例CT做出了正确的诊断，大部分周围型胆管细胞癌的CT表现为肝内不规则低密度肿块边界欠清，增强扫描表现病灶边缘呈不规则环状强化，有向心性强化的趋势，出现延迟强化；病灶内或周围可见结石，病灶内及周围肝内胆管扩张；局部肝包膜回缩、肝叶萎缩，病灶内大片坏死、液化。

Results Cavernous hemangiomas had a enhancement from edge to inside after contrast enhancement scan,and had equal-density with spleen in plain scan. Cystic focus of spleen had not enhanced in contrast scan with lubricous border. Lymphangioma enhanced in contrast scan with multiple round focus.

结果 海绵状血管瘤增强扫描呈边缘强化并向中心充填，延期扫描病灶可完全弥合与脾成等密度；脾囊肿呈圆形或椭圆形囊状占位，水样密度，边缘光滑，不强化为其特点；淋巴管瘤的典型表现是多发低密度灶，可有间隔状强化。

Yes, as a Catholic, my focus is on Christ, but what helps me to keep my focus on Christ is the 'WHOLE TRUTH' handed down by Apostolic Tradition and the Magisterium of the Church.

诚然，作为一个天主教徒，我的重点是基督的，但什么可以帮我把我的重点放在基督是'真相'下达的使徒传统和教会的教堂。
