In practice, when coordinates of two angular of two beam of LD/PSD are measured, people can gained the relative position.

在实际测量中，只要测量双光束LD/PSD 在两个角度时光斑的坐标，即可求得两轴的相对位置。

Based on the relations of the diffraction field and the surface wave, which conclude diffraction factor and interference factor, some relations were conformed such as: the diffraction fringes spatial distribution versus surface wavelength, the fringes half angular width versus the numbers of surface wave covered by laser spots and incidence angle, diffraction intensity versus surface wave amplitude.

通过对衍射因子和干涉因子的分析，得到衍射条纹空间分布与表面波波长的关系、条纹的半角宽度与入射激光光斑覆盖表面波的个数和入射方向的关系、衍射光强度与表面波振幅的关系，并解释了条纹缺级现象。

Along the forward spot, where the radius of the envelope is a hyperboloid, The hyperboloid has asymptote.

Based on the full-width at half-maximum of optical pulse,one can estimate the radius of incident beams and Fresnel biprism's base angle.

根据所测飞秒脉冲的半高全宽，可估算所需光斑大小和菲涅尔双棱镜底角，为菲涅尔双棱镜的选择提供了理论依据。

The system for effective area measurement of laser spot on target plane was designed based on the definition of effective area.

从激光光斑有效面积的定义出发，采用CCD图像摄取技术，设计了一套激光光斑有效面积测量装置。

objective to evaluate the clinical effect of high myopia treated with lasik by a small optical zones flying spot scanner machine.methods 364 cases (721 eyes) of high myopia were treated with lasik by the schwind esiris laser machine with small optical flying spot scanner.the ablation zone was single zone or multi zone.the ablation depth was range of 78～187μm.all cases were followed up for 3～12 months.the changes of their visual acuities,subjective manifest refraction and complications were observed.results postoperatively,at one day and 3 month the visual acuities were 1.0 or better in 72.0%（519/721） and 81.7%（589/721）.the diopter within ±1.00 was 89.7%（647/721） and 90.7%（654/721）respectively.the complications include:decentral ablation 3 eyes (0.42%),decentral flap 5 eyes (0.69%),epithelial ingrowth 5 eyes(0.69%),glare 15 eyes(2.08%).conclusion the clinical effect of high myopia treated with lasik by a small optical zones flying-spot scanner machine was safety and efficacy,although it needs more corneal tissues.

目的 评价小光斑飞点扫描式准分子激光lasik治疗高度近视的效果。方法采用德国schwind esiris准分子激光机对364例（721眼）高度近视进行了lasik治疗。切削模式采用单区或多区切削，切削总量为78～187μm。随访3～12个月，观察术后视力、屈光度和并发症等情况。结果术后裸眼视力≥1.0者，术后1天、3个月时分别为72.0%（519/721）、81.7%（589/721）；术后屈光度在±1.00d以内者，术后1天、3个月时分别为：89.7%（647/721）、90.7%（654/721）。主要的并发症有：偏中心切削3眼(0.42%)、瓣位置偏离5眼(0.69%)、角膜上皮植入5眼(0.69%)、眩光15眼(2.08%)。结论小光斑飞点扫描式准分子激光lasik治疗高度近视的临床效果安全有效，但是需要切削较多的角膜组织。

When comparing myopia treatment times of the star 10HZ, Variable spot scanning 10HZ, and VRR, the study found that treatment times are reduced with VSS and further reduced with VRR.

在将VISX star准分子激光系统进行普通的10HZ、10HZ的VSS变量光斑以及VRR变量重复速率的三种不同的近视矫正手术的时间相比较，研究发现使用VSS变量光斑技术缩短了治疗时间，而使用VRR变量重复速率技术，切削时间进一步缩短。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
