The HRCT and 3D features such as lobulation or unbilication、intratumoral low density areas、short speculation or spine、pleural indentation and arterial supply were found more frequently in small lung cancer.

结节有分叶和切迹，其内密度不均匀、周围有短小毛刺或小棘状突起、伴胸膜凹陷及供养血管等多见于小肺癌。

CT appeared patch,small node,light lobulation,peripheral vessel convergence,pleural indentation sign.

CT表现为斑片状、小结节状、轻度分叶状肿块，小毛刺、血管集束征、胸膜凹陷征，大多直径在1.5～2 cm。

Abstract］ objective to study the knowledge of the imaging manifestation of x-ray and ct in peripheral small lung cancer.methods to collect twenty cases with no symptom in early time diagnosed by clinic and to retrospectively analyze their imaging features.results x-ray appeared patch,small node.ct appeared patch,small node,light lobulation,peripheral vessel convergence,pleural indentation sign.most of the diameter was 1.5 to 2 cm,with no mediastinum and pulmonary hilar lymph nodes diversion.furthermore the clinical symptom was not obviously.conclusion to be familiar and handling the sign mentioned above is the key to boost the diagnosis of small peripheral lung cancer.

目的 探讨周围型小肺癌的x线、ct影像学表现。方法收集临床和病理证实的早期无症状肺癌20例，对其影像学进行回顾分析。结果本组早期肺癌x线为斑片状、小结节状。ct表现为斑片状、小结节状、轻度分叶状肿块，小毛刺、血管集束征、胸膜凹陷征，大多直径在1.5～2 cm。无纵隔淋巴及肺门转移，且临床症状不明显。结论熟悉并掌握上述征象是提高小肺癌早期诊断率的关键。

Just about at the center of the retina is a small depression from 2.5 to 3 mm in diameter known as the yellow spot or macula.

大约正好在视网膜的中心，有一个直径为2.5到3毫米的小凹陷叫做黄斑。

Supposing that the pavement depression is a Ricker wavelet function ,and then the moving vehicle s vibration level induced by it can be obtained by simplifying the vehicle to a two DOF vibration system.

本文将高速公路路面凹陷变形假设为Ricker 小波函数，将车辆简化为两自由度的振动系统，分析了由于路面凹陷变形引起的车辆振动水平。

The effect of the friction between rolls and ring can be ignored and the effect of the spread velocity of rolling on the deformation of ring is illustrated.

通过模拟分析比较，揭示出了环件轧制过程中的金属流动规律：轧制时，环件外侧的变形最大，厚向中心部位变形最小，内侧的变形程度介于中间；环件内外环面的压应力分布和变化规律：在垂直于环件轴线的对称面上，压应力分布近似对称状态，而且在对称面上的应力最大，往端面方向开始减小；指出了环件轧制中轧辊与环件摩擦对环件成形的影响：对于环件的宽展变形，摩擦的影响很小，可以忽略；分析了环件进给速度对环件成形的影响并阐述了环件厚向中心部位凹陷产生的原因，提出防止凹陷的措施：在轧制时，尽量使用快的进给速度有利于防止端面凹陷的产生；研究了导向辊位置对环件成形以及轧辊受力的影响：导向辊的位置对环件的宽展变形影响很小，但对轧辊的受力影响较大，当导向辊的中心位置位于毛坯初始中心位置之上时，驱动辊和芯辊的受力相对较小，这是导向辊导向时优先考虑的位置。

The main distinction of a display face was the lack of "ink traps," small indentations at the junctions of letter strokes.
