Objective: To provide morphological basis for the imageologic diagnosis of extraocular muscles' (EOMs) diseases and their complications. Methods: Frozen fixed orbits of adult cadavers were sawed on marker lines at an interval of 0.5cm to get the serial coronal sections of orbits. Width, thickness,and area of each muscle as well as its positional relations to optic nerve (ON) and orbital wall on 5 consecutive sections of orbits from orbital apex to posterior globe were observed and measured. Results: Maxima...

Objective: To provide morphological basis for the imageologic diagnosis of extraocular muscles' (EOMs) diseases and their complications. Methods: Frozen fixed orbits of adult cadavers were sawed on marker lines at an interval of 0.5cm to get the serial coronal sections of orbits. Width, thickness,and area of each muscle as well as its positional relations to optic nerve (ON) and orbital wall on 5 consecutive sections of orbits from orbital apex to posterior globe were observed and measured. Results: Maxima of the thickness and area of EOMs lie in section 3 or 4, and section 4 holds maximum of the sum of EOMs' areas, but section 3 possesses maximum of the ratio of the EOMs' areas sum to the orbital area. Medial rectus (MR) adjoins close to superior obliquus and ON. Conclusion:The pathologic enlargement of MR more directly impinges on ON. The compression of ON by multiple enlarged muscles can be more accurately reflected on the image of section 3. The developing likelihood of optic neuropathy in Graves' Ophthalmopathy patients can be evaluated through the simphe measurements of orbital image.

目的:为临床眼外肌疾病及其并发症的影像学诊断提供形态学资料。方法:固定成人尸体头颅15个,经低温冷冻后,利用MJ-346B型电动带锯做眼眶连续冠状断层(层厚0.5cm,锯耗0.1cm),观测眶尖至眼球后极5个连续层面上眼外肌的宽、厚、断面面积及其与视神经、眶壁的位置关系。结果:眼外肌厚、断面面积最大值均分布于眶的第3或第4层面,眼外肌断面面积之和的最大值在第4层面,其面积和平均为128.54mm~2,而第3层面眼外肌断面面积之和占眶断面面积的比例最大,平均占29%;内直肌与上斜肌、视神经的距离最近,因而其毗邻关系最为密切:结论:内直肌的病理性肥大对视神经的压迫更为直接;当多条眼外肌同时肥大时,第3层面的影像表现更能反映眼外肌对视神经的压迫程度;还可通过眶断面影像上的几个简便测量来评估眼型Graves病人发生视神经病变的可能性。

The northern region of loess plateau in China, where is cross water-wind erosion, is typical ecosystem environment fragile zone with serious soil erosion. The research on soil erosion prediction is very urgently. However, due to special geography of loess plateau, social and economic condition, the application of oversea prediction models is suffered to limit. We must develop a suite nation situation prediction model. For this, according to the purpose to predict soil erosion, we propose a soil erosion ecological prediction way. The Liudaogou small watershed, which is located in cross zone of water-wind erosion in the north of loess plateau in China, is taken as studying area. According to theprinciple of soil erosion, we select some main affecting factors as cartographic generalization objects. They respectively are landforms surface material composition, slope gradient and land utilization ways. On the based of cartographic generalization with GIS, according to combinatorics principles, the ecological landform unit is formed. In the Liudaogou small watershed, there are 83 kinds of ecological landform unit scattered in (284) plots. The soil erosion basically occurs on wasteland, slope land and sparse shrub land with the slope gradient of 15°~25°, and their areas sums up about 50% of whole watershed.

土壤侵蚀预测预报的目的是为治理水土流失、合理利用土地资源而服务的,所以说土壤侵蚀的预测预报单元应落实到一个具体的土地利用生态地形面上。以黄土高原风蚀水蚀交错带的六道沟为研究区,基于土壤侵蚀的发生学原理,首先将各主要发生因子的图件数字化,并通过GPS对数字化图进行校正;然后,对地形条件、物质组成、土壤相三图件进行制图综合,生成流域侵蚀地块图;在此基础上,迭置土地利用类型图,在GIS平台上,生成土壤侵蚀预测最小单元图——生态地形面图。在每类生态单元内,系统分析土壤侵蚀发生的各环境要素,并确定其权重,应用组合数学原理,建立适合于当地环境整治、水土流失治理的土壤侵蚀生态预测系统,为建立适合我国土壤侵蚀预测预报模型提供一些基础依据。
