毛刺

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。

Results: CT findings of pulmonary inflammatory masses were characterized by smooth or partially obscurely-defined or spiculated edges with no distinct lobulation. Morphologic features as cavity, local pleural thickness and adhesion, thickened and increased peripheral lung markings were seen in those cases.

结果：肺部炎性肿块主要的CT表现是边缘清楚或部分欠清，无明显分叶，可有长毛刺，空洞，胸膜增厚粘连，周围肺纹理增多增粗等。

CT scanning can provide more information about peripheral pulmonary carcinoma than routine X-ray.The lobulation,spicules and pleural indentation around the mass suggest the diagnosis of pulmonary carcinoma.

CT诊断周围型肺癌比常规X线检查提供更多的信息；若CT发现肺部周围结节或肿块有分叶、毛刺及胸膜凹陷征等应考虑为肺癌，肺门、隆突下及纵隔淋巴结肿大且无钙化时，要考虑肺癌向淋巴结转移。

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。

On the whole,burring this kind of bearing maintainer is realized by high efficiency and high quality.

传统的滚磨去毛刺加工，是将被加工零件和磨料自由地混合在一起，加工时

It was found that introducing 15 g/L additive containing 1.5 g saccharin helped to well retard electropolishing-induced corrosion of the electropolished improve the quality of the electropolished moldboard surfaces. At the same time, it was feasible to realize satisfactory precision electropolished of the laser moldboard made of stainless steel at a current density of 20~25 A/dm^2, duration of 1 min, and temperature of 60~65 ℃. The resulting polished moldboard had smooth walls and bright surface, while the corrosion was less than 0.005 mm.

结果表明，添加剂含量在15 g/L时能有效抑制抛光的腐蚀量，提高抛光质量；在精抛光的参数电流密度为20~25 A/dm^2，温度60~65℃，时间1 min条件下，钢片经去毛刺处理和精抛光处理能达到孔壁光滑、腐饮量小于0.005 mm的要求。

The target of the control system is to maintain constant normal force and tangent speed when following or deburring a workpiece.

最后，进行了边缘跟踪及打毛刺实验，分析了在不同速度及不同正压力下，对力均方误差的影响。

In carrying out the printing plate second exposure, we then press the required size and cutting film red film that cut out red film area should be slightly larger than the demand from the area of the adjudication, with one side must, as a straight line, and there is no red film Burr.

在举行印版第二次曝光的同时，我们再按请求的尺寸裁切胶片赤膜，其洋所裁切不入的赤膜面积答稍大于印版的需求局部的面积，有一外务必裁齐，不败一条曲线，且无赤膜毛刺。

Results The growth rate of rMSCs induced by RPE cells lysate was slower and protuberant burr surrounded the fusiform cells.

结果 经RPE细胞裂解液诱导的rMSCs生长速度减慢，细胞呈长梭形，周边有毛刺样突起。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
