Results The occurrence of aggressive NK cell leukemia was found to be higher in Asian. Most of its patients were young. The clinical features were found to be high fever and sweat involving the liver, spleen and lymph nodes and bone marrow, hypohepatia, reactive hemophagocytic syndrome, and hypocytosis, etc. Immunophenotype expressed CD2, CD7, CD16 and CD56.

Results MRI appearances of acoustic neuromas were:（1）The turmor's growth round the internal auditory canal,the Ⅶ,Ⅷ nerves affected side were thickened than that of opposite side.There was no marked demarcation between the main bodies of the tumors and the affected nerves.The connection between tumors and affected nerves could be showed at contrast enhanced imaging.（2）The tumors were of hypo or isohypo intensity on T1 weighted images and hyper or iso hyper intensity on T2 weighted images.（3）After Gd DTPA administration the tumors were homogeneously or inhomogeneously or circularly enhanced.（4）The margins of the tumors were smooth and well delineated.（5）The affected internal auditory canal usually became shorter in depth and larger in posterior anterior diameter.（6）MRI appearances of micro acoustic neuromas were that the affected Ⅶ,Ⅷ nerves were normal in size or nodularly thickened and the tumor reveaed nodular or point enhancement at contrast enhanced MRI.

结果 听神经瘤的MRI表现主要为：（1）肿瘤以内听道为中心生长，第Ⅶ、Ⅷ神经束较对侧增粗，与肿瘤主体多无明确分界，增强后可见两者相连，颇为特征；（2）肿瘤在T1加权图像上呈低信号、略低信号或低等混合信号，T2加权呈高信号或高等混合信号；（3）注射Gd DTPA后肿瘤呈均匀、不均匀或环状强化；（4）肿瘤边界清晰，边缘光整；（5）绝大多数肿瘤患侧内听道前后径扩大，深径缩短；（6）微小听神经瘤的MRI表现为第Ⅶ、Ⅷ神经束正常或局部结状增粗，造影后呈结节状或点状增强。

结果］长骨骨化性纤维瘤具有一般良性骨肿瘤的特征，表现为骨干骨皮质内的溶骨性破坏区，边缘多有硬化缘，其内可见钙化或骨化影，周边无软组织肿块和骨膜反应，特别是发生于胫骨前端骨皮质的具有上述表现的病灶。

Results There was not specificity of clinical symptoms in liposarcoma of the orbit, the major clinical aspects were intraorbital occupied lesion and local hyperaemia,swell and pain which was similar to an acute inflammation. Four different subtypes of liposarcomas could be observed in orbit.In past literature,myxoid was the most common subtype（14 cases,70%）,secondly subtype was well differentiated（3 case）,round cell and pleomorphic subtype were rare（each 1 case）.This case was well differentiated mixed component of round and pleomorphic lipoblasts.

研究结果表明，生长季内海三棱藨草带大型底栖动物的多度和生物量整体呈上升趋势，但是月间存在一定波动变化，9月份多度最高，平均为1536ind／m^2，10月份生物量最高，平均为21.60g／m^2；不同月份优势类群组成、多度及生物量特征存在明显差异，瓣鳃类仅在部分时段表现出优势特征。

The results showed that:(1)All of the five legume grass in Songnen Plain displayed assembling distribution pattern at inter-community level, of which Lathyrus quinquenervius,Vicia multicaulis,Lathyrus hedysaroides,Lathyrus davurica displayed assembling distribution pattern at intra-community level, while Medicago ruthenica tended to be random distribution.

结果表明：（1）松嫩平原五种豆科牧草在群落间大尺度层次上均表现为聚集分布格局；在群落内，五脉山黎豆，多茎野豌豆，细叶胡枝子，兴安胡枝子均表现为聚集分布；花苜蓿的聚集程度较低，并趋于随机分布。

In the first part, the thesis mainly checks the concept of urban and rural dual structure, manages to give it a philosophic, definition and then lists various conducts of the contradiction. It also analyzes the subjective and objective reasons that cause the Chinese urban and rural contradiction, and dissect the contradiction抯 feature, history, current situation and influence. This part means to explain that China is a prototypic developing country with Chinese characteristic urban and rural dual structure co!~tradiction. The incisive contradiction exists mainly in seriously backward countryside. In the fields of economy, politics, culture etc, it badly affects and restrains our economy and society抯 sustained, rapid and coordinated development manifoldly and omnibearingly.
