Abstract］ objective to improve the diagnosis of non-ossifying fiboma by analysing its x-ray feature.methods plain x-ray films was performed in all patients.x-ray finding in 8 cases with pathologically-confirmed non-ossifying were analyzed.results the clinical symptom was mild,the lesions occurred usually at the metaphysis of the long bones,the affected bones included femur（n=4）,tibia（n=3）,humerus（n=1）.cortical type was seen in 5 cases,presenting as unilocular or multilacular transparent areas with in the cortex or tightly beneath the cortex,the lesion had a sclerotic margin.which was more obvious at the marrow side.medullary type was seen in 2 cases.the lesion was located at the center of the bone and grew centrally.the tumor was manifested as unilocular or multilocular.tramsparent area with sclerotic border and the bone cortex became thinner with slightly expanding on 11 sides.conclusion plain radiography is the elementally means to detect this disease.based on the typical x-ray signs of non-ossifying fibroma combined with clinical data,correct preoperative diagnosis can be made in most cases.

目的 探讨非骨化性纤维瘤的x线表现以提高诊断水平。方法所有病例均摄有x线平片，分析经病理证实的8例非骨化性纤维瘤。结果临床症状轻，好发于下肢长骨干骺端或骨干，股骨4例，胫骨3例，肱骨1例。皮质型5例，表现为皮质内或紧贴皮质下的单层或多层透亮区，病变向骨内发展进入髓腔，周围有致密硬化带环绕，以髓腔侧明显；髓质型2例，病灶在骨内中央发展，显示为单房或多房透亮区，边缘有硬化，骨皮质菲薄，轻微向周围膨隆。结论 x线为最基本的检查方法，典型病例x线平片结合临床症状即可明确诊断。

Sympegma regelii community, a rangeland desert vegetation, has the highest Shannon-Winner species diversity indices (1.706); the communities of Haloxylon ammodendron and Ephedra przewalskii, which have obvious feature of desert vegetation, are in the middle in species diversity indices (0.875-0.890); the communities of Calligonum mongolicum, Populus euphratica, Tamarix ramosissima and Glycyrrhiza inflata, characterized by desert forest of which saline desert bushes and saline meadows are scattered in the communities, have lowest value of the species diversity indices (0.079-0.495). 3 The structure of desert plant community is dominated by the bush layer. The species diversity indices of bush layer (0.769-1.451) is much higher than that of herb layer (0.193-0.254), and the diversity in herb layer is strongly influenced by bush layer. 4 The species diversity of desert plant communities shows a gradient of change with respect to longitude, latitude and elevation. For example, rangeland plant Sympegma regelii, with a high level of diversity indices (1.706), is in transition to desert plants Haloxylon ammodendronn community (with a low level of diversity indices of 1.379) in a longitude gradient and to saline Tamarix ramosessima community (with a low level of diversity indices of 0.376) in a latitude gradient. Calligonum mongolicum community, with a low level of species diversity (0.819), is in transition to Ephedra przewalskii (with a low level of diversity indices of 0.890) and Haloxylon ammondendron community (with the diversity indices of 0.645) in an elevational gradient.

群落Shannon-Wiener物种多样性水平表现为合头草群落最高(1.706)，具有草原化荒漠植被类型的成分；梭梭群落、膜果麻黄群落居中(0.875~0.890)，荒漠植被类型特征明显；沙拐枣群落、胡杨群落、多枝柽柳群落、胀果甘草群落较低(0.079~0.495)，荒漠林、盐地沙生灌丛及盐化草甸植被均有零星分布。3荒漠植物群落结构层次中，灌木层占居主导地位，群落灌木层物种多样性水平(0.769~1.451)远远大于草本层(0.193~0.254)，且草本层物种多样性受灌木层影响较大。4荒漠植物群落物种多样性分布格局表现为经向、纬向和海拔梯度的变化，经向、纬向变化为物种多样性水平较高的草原化植物合头草群落(1.076)向物种多样性水平较低的荒漠植物梭梭群落(1.379)和盐化植物多枝柽柳群落(0.376)的过渡，海拔梯度则呈现低水平的沙拐枣群落(0.819)到高水平的膜果麻黄群落(0.890)向低水平的梭梭群落(0.645)变化。

Polysemy is discussed from the perspective of prototype, cognitive metaphor and metonymy, discovering that a polysemic word constitutes a semantic category with its primary meaning as the prototype while other members in that category are derived from it, exhibiting a family resemblance and degrees of typicality as well, and that the extension of word meaning is mainly achieved through metonymical thinking based upon contiguity and metaphorical thinking based upon similarity.

利用原型范畴理论、认知隐喻和转喻角度分析一词多义现象，认为一个词的多个义项是从原型义项演变而来的，并且表现出不同程度的家族相似性，同时又表现出不同程度的原型义项身份；词义延伸又主要通过转喻和隐喻的认知思维结构，即转喻的邻近性和隐喻的相似性思维特征来实现。
