Objective To assess the value of spiral and cine CT for the diagnosis of foreign body in trachea in children.

目的 探讨螺旋CT和同层动态CT电影诊断小儿气管异物价值。

PDCA can be an independent circle to solve an independent problem.

PDCA可能是一个独立的环，如解决一个独立的问题，当这个问题解决了，那么这个环也随着消失了；也可能是一个持续改进的过程，即螺旋上升过程，即当这个问题没有解决或已经解决了但又有新的问题发现，又会根据这个问题，进行下一个PDC循环。

Cases were observed injury of knee joint cruciate ligaments merely.1 case with rupture of knee joint cruciate ligaments was not observed in CT images. The accuracy was 93.33%. The injury of tendon and ligament such as the rupture, thickening, hydropsia and circuity also were showed by 16-slice spiral CT image.

在15例膝关节交叉韧带损伤病例中，8例交叉韧带损伤伴撕脱骨折诊断明确，6例单纯交叉韧带断裂诊断明确， 1例韧带断裂未显示，诊断准确率为93.33%。16层螺旋CT可显示肌腱的断裂、增粗、水肿和迂曲等。

16-slice spiral CT by all kind of imaging ways could clearly display the anatomy and the pathologic changes of tendon, muscle belly and ligament such as the rupture, thickening, hydropsia and circuity, provided a effective way to diagnose the closed injury of antebrachim tendon and cruciate ligaments of knee joint.

应用16层螺旋CT检查前臂肌腱损伤及膝关节交叉韧带损伤，其多种成像方法能够清晰地显示各肌腱、肌腹与韧带的断裂、迂曲、增粗和水肿等病理改变与解剖关系，为临床诊断和手术治疗提供有力的依据，具有重要的参考意义。

We have also presented the ω-circulant boundary condition and compared it with the helix boundary condition. Furthermore, we can also get another new boundary condition: the mixed boundary condition.

由此我们提出了ω循环型边界条件并将其与普通循环型及螺旋型边界条件作了分析和比较；进一步地，得到了一种新的边界条件：混合型边界条件。

In this paper,a kind of flexible cantilever beam electromagnetic optical switch which is used in the wave length channel selection system was designed and fabricated. It is manufactured by MOEMS technology and composed of a plane circular coil in flexible polyimide cantilever beam, cylindrical permanent magnet,substrate and reflector prism with two reflecting surfaces.

设计并制作了一种用于波长信道选择系统的新型柔性悬臂梁电磁驱动光开关，该光开关采用MOEMS技术制作，由带有平面螺旋形线圈的聚酰亚胺悬臂梁、圆柱形永磁体、基座以及双面反射棱镜组成。

The circular helix is a regular curve on the surface of a circular cylinder.

这个圆柱螺旋线是在圆柱体表面的一个正则曲线。

When analyze the stability of slopes, traditional methods often use suppose that the failure surface is circular or other typical functions.

在对边坡的稳定性进行分析评价时，传统分析方法引入了滑裂面为圆弧型的假设；也有学者将滑裂面假定为对数螺旋线型等其它函数形式。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
