屈光的

Solar-charged lights designed by Patrick Walsh, founder of Greenlight Planet, are one solution to this problem.

由绿光星球的创始人派屈克沃尔什设计的太阳能充电灯，对此问题是一种解决的办法。

Preiss angle (P .0l ), for the stick pestle can complement the strength for correcting the broadenth of the cross radius of the calcaneus, and the plaster splints are strong enough to fix the ankle firmly at the metatarsus posture.

第二部分为生物力学的实验研究，采用电测法与三维光弹性实验，研究跟骨在中立位及不同角度的跖屈位时应力分布的规律，分析跟骨在不同体位时应力和位移情况，探讨跟骨骨折的发病规律及合理的治疗方法。

The results show that the fractography is woody structure, there is a great deal ferric oxide in the hair seam, its matrix is composed by the ferrite, the pearlite and a little of sorbite and troostite, the grain size is 9～10 levels primarily, there are obvious zone structure and inclusions, which are silicate, sulfide and a little of oxide.

结果表明：弯裂带钢的断口呈木纹状，发纹处存在大量氧化铁，其基体主要由铁素体和珠光体组成，有少量索氏体及屈氏体，晶粒度以9～10级为主，有较为明显的带状组织，夹杂物为硅酸盐、硫化物及少量氧化物。

Shapes of spectral distributioncurve in pure Kuroshio region and coastal waters are obviously different.Some inflectionpoints in spectral distribution curve appear at wavelength bands of 412,443,490,520,550,555 and 670nm.

黑潮域与沿岸水的水中辐射光普曲线之形状呈显著的差异，并使得水中辐射照度分布曲线於412、443、490、520、550、555及670 nm波段处出现了屈折点。

Its axial resolving power depends on the coherency of light source,even 10μm,and the depth it can cut through isn't limited by the eye's transparent diopter medium.You can observe the structure of not only optic anterior ganglion but also posterior ganglion.It has a brilliant applied prospect in the diagnosis of entoptic disease especially retinal disease,随访观察 and evaluation of treatment result.

OCT是超声的光学模拟品，但其轴向分辨力取决于光源的相干特性，可达10um，且穿透深度几乎不受眼透明屈光介质的限制，可观察眼前节，又能显示眼后节的形态结构，在眼内疾病尤其是视网膜疾病的诊断，随访观察及治疗效果评价等方面具有良好的应用前景。

AbstractAIM: To study the changes of refractive status and axial length in chicken form deprivation myopia and its recovery model, to observe the metamorphism of posterior sclera and to lay foundation for investigation of axial myopia pathogenesisMETHODS: Twenty-five newly incubated chicken were selected. Their left eyes were covered with semi-translucent membrane to deprive form perception for 14 days (form-deprivation group), or covered for 11 days followed by uncovered for 3 days. Unoccluded eyes in either group served as control eyes respectively. Retinoscopy and A- ultrasound were conducted to collect the refraction and axial length data.

目的：研究雏鸡形觉剥夺性近视眼及形觉剥夺性近视眼恢复模型的屈光状态和眼轴长度的变化，并观察后极部巩膜的形态学改变，为探讨轴性近视的发病机制打下基矗方法：选用新孵出的普通肉食家鸡25只，采用半透明薄膜眼罩遮盖的方法对左眼进行形觉剥夺14d或遮盖11d后，去遮盖3d。

The purpose of fogging is to relax accommodation by creating an artificial myopia in all eyes regardless of their original refractive status.

9雾视法的目的在于使被测眼的调节松弛，不论其原来的屈光状态如何，被测眼均处于人为的近视状态。

The explanations of the phenomena of sight put forward by Young, von Graefe, Helmholtz and Donders have caused us to ignore or explain away a multitude of facts which otherwise would have led to the discovery of the truth about errors of refraction and the consequent prevention of an incalculable amount of human misery.

阳·冯·格雷夫、赫尔姆霍茨和唐德斯对视觉现象的解释，使我们不再理会或辩护大量的事实，否则，就会导致屈光不正真相的发现，并相应的预防一个无法估量的人类苦难。

If------ By Joseph Rudyard Kipling If you can keep your head when all about you Are losing theirs and blaming it on you; I f you can trust yourself when all men doubt you, But make allowance for their doubting too; If you can wait and not be tired by waiting, Or, being lied about, don't deal in lies, Or, being hated, don't give away to hating, And yet don't look too good, nor talk too wise; If you can dream---and not make dreams your master; If you can think--- and not make thoughts your aim; I f you can meet with Triumph and Disaster And treat those two imposters just the same; If you can bear to hear the truth you've spoken Twisted by knaves to make a trap for fools, Or watch the things you gave your life to broken, And stoop and build 'em up with worn-out tools; If you can make one heap of all your winnings And risk it on one turn of pitch-and toss And lose, and start again at your beginnings And never breathe a word about your loss; I f you can force your heart and nerve and sinew To serve your turn long after they are gone, And so hold on when there is nothing in you Except the Will, which says to them: hold on!

翻译成中文就是假如——假如你能——在别人不知所措却对你横加指责的时候，保持清醒的头脑；假如你能——在所有人都怀疑你的时候仍然相信自己，并能体谅别人对你的怀疑；假如你能等待且又充满耐心，或者，从不用谎言去应付谎言，也不用仇恨去回击仇恨，既不故作正经也不夸夸其谈。假如你充满梦想——但绝不做梦想的奴仆；假如你勤于思考——却不把思想当作目标；假如你能——在遇到胜利和困难时态度同样平静；假如你能容忍你所说的真理，被无赖用作捕捉愚人的陷阱，或看着你所献身的事业轰然倒塌，你能屈身拾起残破的工具把它们重建。假如你能——把所有赢来的筹码都押在一把赌注上，输光后仍能重新再来，且对输赢只字不提。假如你能——在运气不佳身心俱疲之时，仍能全力以赴抓住机遇，在一无所有只剩意志支撑的时刻，咬牙坚持到底。
