将以上方法用于实际数据的处理中，对一组透镜表面数据进行拟合、分析，最终得出透镜的表面形状误差、各点的切矢、曲率半径误差以及光线的聚焦误差，并用matlab仿真出曲线图。

Wagons shot past with furious speed and crushing loads,bearing, perchance, among the rest, the agent of the Insurance Company, who was bound to go however far; and ever and anon the engine bell tinkled behind, more slow and sure; and rearmost of all,as it was afterward whispered, came they who set the fire and gave the alarm.

在狂怒的速度下，车辆飞去如飞矢，坐满了人，其中说不定有保险公司代理人，不管火烧得离他如何远，他还是必须到场的；然而救火车的铃声却越落越后，它更慢更稳重了，而在殿军之中，后来大家窃窃私语他说，就有那一批放了火，又来报火警的人。

The purposes of this study were (1) to compare the differences of the transverse craniofacial morphology between the adult high-angle and low-angle facial skeletal types, and (2) to correlate the width measurements with data obtained from PA roentgenogram. Thirty-seven adults, 18 to 22 years old, with varied vertical facial types were separated into two groups: seventeen high-angle, twenty low-angle facial skeletal types.

高低角骨面型是垂直向发育异常所造成的两种极端骨面型，近年来逐渐成为学者们研究的热点，目前的研究大多是基于头颅侧位X线片从矢状向和垂直向进行比较，而未查及高低角骨面型横向颅面结构的系统性研究。

In using DGF method, the first thing is to obtain the proper form of certain area. But the DGFs obtained now are all in achiral medium. So people are eager to know DGFs in spectral domain and space domain of chiral medium.

用解析的方法求解电磁场的边值问题主要依靠建立在经典电磁场理论基础上的并矢格林函数方法，应用DGF方法首先要找出适用于相应区域中的DGF形式，而现有的DGF形式都是基于非旋波媒质情形。

The directions of insertion on the articular process in the sagittal plane and horizontal plane were determined according to the relationship between the spinous process of vertebra and vertebral body in the X-ray film.

根据脊椎的棘突与椎体在X线片上的关系，在术中确定Dick钉在关节突处进针点上的矢状面和水平面上的进针方向，未用X线机辅助。

The main different between the Land Raider and the Prometheus is its weaponsry. the quad-mounted heavy bolters in each sponson replace the Land Raider's lascannons.

基本型兰德掠袭者与普罗米修斯型之间最主要的不同在于他们的武器系统，四联装的重型爆矢枪取代了两侧的光束加农炮。

In this article, the general finite element software ABAQUS is adopted to set 3D model and to simulate the construction of pit excavation. Furthermore, it analyzes the loading and deformation of the non-pin build-up arch structure systemically based on the following aspects: the embedding depth, the depth of pit excavation, the thickness of crown, the diameter and length of the springe, ratio of rise to span .

本文采用大型有限元程序Abaqus建立三维模型，模拟基坑开挖的施工过程，对具有无铰拱特性的组合拱结构从拱的插入深度，基坑开挖深度，拱冠厚度，拱脚直径和长度，矢跨比等方面进行了受力和变形的系统分析。

On the basis,the effect of different factors such as the arrangement of lateral brace,the sloping angle of arch ribs,the stiffness of bridge deck system,the effect of non-orientedly conservative loadings of the hanger and tie bar etc is discussed.

在此基础上，本文还通过有限元模型分析，就拱的矢跨比、吊杆的非保向力效应、桥面系的刚度、横撑布置形式、拱肋侧倾角等因素对该桥整体稳定性的影响展开探讨与研究。

This displayed the serial transversal, coronary and sagittal sectional anatomy of the oculomotor nerve, trochlear nerve, trigeminal nerve, abducent nerve, facial nerve, vestibulocochlear nerve and lower cranial nerves and their related structures, which provides basis of sectional anatomy for imaging study of the cranial nerves.

采用生物塑化技术，制作了层厚为1.0mm的薄层断面切片，系列地显示了动眼神经、滑车神经、三叉神经、外展神经、面神经-前庭蜗神经、低组脑神经及其相关结构的横断、冠状和矢状位薄层断面形态，为脑神经的影像学研究提供了对应的薄层断面解剖学基础。

Depending on the clinical situation, the goals of such surgery may include spinal cord or nerve root decompression, restoration of sagittal alignment, and avoidance of complications such as pseudarthrosis, anterior graft dislodgement, and adjacent segmental degenerative disease.

跟据临床情况，这些手术的目的可能包括脊髓或神经根减压、矢状面排列的恢复和避免并发症，如假关节形成、前方植骨块的脱出和临近节段的退行性疾病。
