Objetive To discuss the value of spiral CT and Multispiral CT pulmonary angiography in the diagnosis of pulmonary embolism and it,s clinical used.

G$FTNCut0 ［摘要］目的：探讨螺旋CT肺动脉造影、多层螺旋CT肺动脉造影对肺栓塞的诊断及临床应用价值。

Focusing properties of Gaussian beam induced by nonspiral and spiral phase plates are investigated numerically.

研究了高斯光束经过非螺旋和螺旋两种相位片后的聚焦性质。

The nonspiral phase plate introduces phase singularity to the incident beam, and the spiral one adjusts the radial phase distribution.

非螺旋相位片将一个光漩涡引入高斯光束，螺旋相位片调节光束径向波前相位分布。

And local dark focal spots may be obtained, the focal spot may evolve into a circle, a two-peak spot, or a curve line, which indicates that the combination of nonspiral and spiral phase plates can be used to form novel focal spots.

随着相位片参数变化，焦斑可演化成环形焦斑、具有两个光强峰值的焦斑、或是曲线形焦斑，这些现象说明可以将螺旋和非螺旋两种相位片结合用来调节焦点光强分布，得到新型焦斑。标签相位片焦点移动焦点破裂光陷阱

Tank Hunters in helixes will outrange RPGs in Buses, so you can stay slightly out of the range of Buses but still pelt them with Rockets.

螺旋内的坦克猎手可以向外，凌驾于战斗巴士对其开火，所以你可以轻松的将螺旋停在战斗巴士射程之外但是依然可以对它们射击。

The coiling testicular artery was thin and showed regular coiling. The testicular artery was surrounded by Pampiniform vein plexus and did not cut through Pampiniform vein plexus in control group.

对照组睾丸动脉较纤细，进入腹股沟管之前为蛇行，然后出现迂曲并渐呈螺旋状，在腹股沟管内，睾丸动脉外围蔓状静脉丛，一般不穿出静脉丛之外；DM组同对照组，整体观未见明显病变，但走行不规则，未见明显的螺旋状；睾丸动脉外围蔓状静脉丛，动脉走行不规则，可穿出静脉丛之外。

Objective: To describe the anatomy of the superior and inferior aspect of the perirenal space as well as the renal fascia with CT radiography in vivo.

目的：通过对正常成人活体肾周间隙和肾筋膜的多层螺旋CT及三维重建图像的观察和测量分析，探讨肾筋膜的附着、肾周间隙的纵向通连情况等相关指标，以及多层螺旋CT对肾周间隙通连研究的诊断价值。

Abstract］ Objective To investigate the value of spiral CT on the diagnosis of pulmonary injury caused by polymyositis and amyopathic dermatomyositis.Methods The lungs of 7 patients diagnosed dermatomyositis were scanned by American four-slice spiral CT.

目的 探讨螺旋CT在诊断发性肌炎和无肌病性皮肌炎肺损害的价值方法使用美国GE四层螺旋CT机对我院的7例确诊皮肌炎患者的肺部进行扫描。

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
