查询词典 conical cornea

In this paper, based on a pill-box window model with a conical-shaped alumina ceramic and Ansoft HFSS software, the relation of VSWR with various electrical parameters in the window is simulated; the effects of variations of the output window structure on electrical field intensity, microwave power flow and quantity of heat are analyzed; the electrical characteristics of frequency bandwidth, power capability and heat dissipation for the pill-box window with conical-shaped or disk alumina ceramic are discussed, which shows that, with a rational structure of the window with conical-shaped alumina ceramic, the output capability of microwave peak and average power may greatly be increased, the secondary electron emission may effectively be suppressed, and heat dissipation may become more uniform and be easier for cooling.

本文在前人工作的基础上，基于圆锥形陶瓷盒形输出窗模型，采用Ansoft HFSS三维计算软件的优化模拟，对该输出窗模型的驻波频率特性与各种结构参量的关系进行了优化模拟，分析了该输出窗片结构变化对其表面的电场分布，功率流分布、热量分布的影响，得出最优模型参数。并且探讨了陶瓷窗片的形状和几何结构对改善输出窗的频带特性、提高峰值功率和平均功率、抑制二次电子倍增方面的作用。

Objective: To detect the expression of PDGF-B in rat cornea after cautery with alkali and the value of PDGF-B in corneal wound healingMethods: Cornea was wounded by cautery with alkali in sparague dawley rats.

目的 检测血小板源生长因子在大鼠角膜碱烧伤后表达的变化，探讨PDGF在角膜损伤修复过程中的作用和意义。

After 1-month treatment, his best corrected visual acuity improved from 0.05 initially to 1.2, and the corneal thickness was not different between eyes. Nevertheless, at the injured sites, cornea was apparently thicker and corneal endothelial densities were lower than those in the fellow eye. This cornea might decompensate after any other ocular trauma or intraocular surgery.

经过一个月的治疗后，视力、眼压、中央角膜厚度、角膜上皮、前房、视网膜等皆恢復正常，但角膜內皮细胞密度明显减少，受伤部位的角膜亦明显较厚，日后恐有角膜失偿的危险，而这种情况无法藉测量中央角膜厚度显示出来。

During the follow-up of 6 months, epithelization of the cornea was completed within 2 weeks, and less cicatricial pterygium, symblepharon and cornea neovascularization complications were noted, visual acuity was significantly improved.

随访观察，术后角膜创面上皮化大多在2周内完成，无明显新生血管增生和假性胬肉及睑球粘连等并发症发生，视力较术前显著改善。

Abstract］ Objective To enhance the propaganda of knowledge about eye bank and increasing the source of donated cornea ,and investigate the methods and strategy of increasing the donation of cornea.

摘要］ 目的扩大眼库知识宣传和角膜移植供体来源，探讨促进角膜捐献的方法和对策。

During your presurgical eye exam, your eye doctor uses highly specialized instruments to determine which specific areas of your cornea need to be flattened or curved. This allows your eye doctor to chart your eye and remove tissue from your cornea very precisely.

你的眼科医生在手术前的眼睛测试时使用很专业的仪器确定手术面积——需要变平或者变弯的角膜面积，然后绘制你的眼睛图，并且从角膜上精确地移除组织。

Abstract］ Objective To discuss the prevention and treatment of cornea eyewinker.Methods To take different measure to eliminate cornea eyewinker.

目的 探讨角膜异物的预防和治疗方法采取不同的治疗措施剔除异物。

Results Bleeding occurred on the top of the cornea in 30 eyes(58.8%) and in lower part of the cornea in 9 eyes(17.6%),12 eyes had bleeding at 2 spots(23.5%);half month after operation,overcorrection was found in 30 eyes,undercorrection in 11 eyes,5 eyes showed irregular astigmatism;7 eyes were operated on again to raise eyesight.

然而，由于角膜瓣的缘故，临床治疗中有部分病人发生出血，对手术后的疗效产生了不同程度的影响。
