The adjacent structures or organs were compressed and shifted. Results The CT features of different tyres of CSIF Will help us better know the location of subhepatic spaces,also the location of peritoneal and retroperitoneal cavity. It will play an important role in the diagnosis and the differential diagnosis of the revalent diseases.

通过认识不同类型的肝脾曲结肠综合征CT影像表现，使我们对膈下间隙的影像定位进一步明确，对腹膜前后腔的界定，在解剖意义上又增加了一些佐证，对相关的疾病认识及其鉴别诊断将起重要作用。

In this paper,we chosed the Piranha package LED as lighting sourse,and designed the reflector cavity and pillow lens,and built the 3D model of tail lamp in the structure software Catia,and obtained the optical simulation results of tail lamp in the optical simulation software TracePro,and we succeed in developing a LED tail lamp in last;After the testing in automotive lamp center,it was proved that our lamp achieved the national standard of automotive lamps.

摘 要：采用食人鱼系列的发光二极管(light em itting d iodes，简称LED)作光源，进行枕型透镜与反射腔的设计，在结构软件Catia中建立了一款后位灯的三维模型，并利用光学软件T raceP ro进行光学效果的仿真，开发出了一款LED后位灯。样品经汽车灯具测试中心检测，性能满足国家标准要求。

On the 14th day after yolk sac had disappeared, gonad had differentiated to ovary.

Methods: Sixty samples of hip were harvested for this study. The width and thickness of labrum were measured on nine positions: midsuperior, anterosuperior 30°, 60°, 90°, 135° and posterosuperior 30°, 60°, 90°, 135°. The positions and size of labral tears were observed and the increasing volume of coxal cavity was measured.

取成人髋关节标本60个，测量髋臼唇在距髋臼顶点前后30°、60°、90°、135°处的宽度和厚度，观察髋臼唇撕裂的位置，测量大小，测量由髋臼唇增加的髋臼腔的容积。

The structures of the ""lungs"" have an evolution trend from lower to higher through Lepidoptera to Hymenoptera. 5. If the function of the ""lungs"" is extended into to ""aerating trachea"", the larvae of Apidae, Muscidae and nymphs of Coleoptera, Hemiptera also may have the function of the ""lungs"". Our researches are supplement and support to Locke's researches and an important progress in insect physiology.
