objective to evaluate early signs of avascular necrosis of femoral head in adult by ct and to guide clinical treatment.methods the cases with suspicious diagnose of anfh were scaned in the both hip joints by x ray and ct to find the early signs of anfh with ct.results early signs of anfh using ct showed that, in 38 femoral heads 31 cases, there were radiate star shape of high density osteosclerosis of the trabeculae in 13 femoral head.twenty five femoral heads showed osteosclerosis and trabeculae structure disappearing and vague,incoordinately low ostedensity area and cyst change.there were fracture under the cartilage and light subsid in 5 cases.the cases in stage ⅰwere given decompression, while the pationtsresul in stageⅱand stageⅲ were given decompression and ostetransplant.conclusion ct results show that the sign of the high osteodensity and low osteodensity and cyst change can disply early anfh.

摘 要］目的：探讨成人股骨头缺血性坏死的早期ct征象并指导临床治疗。方法：对临床疑诊anfh的全部病例均行x线平片及ct检查，分析anfh的早期ct征象。结果：早期anfh的ct表现：31例38个股骨头，其中13个股骨头骨小梁呈放射状高密度的"星状征"，骨小梁境界清楚、锐利，属ⅰ期；25个股骨头表现为骨硬化，骨小梁结构消失、模糊不清，骨密度减低及囊性改变，属ⅱ期；并有5个股骨头在ⅱ期影像学改变基础上出现软骨下骨折及轻微塌陷，属ⅲ期。治疗结果：ⅰ期行钻孔髓内减压术，ⅱ、ⅲ期行钻孔减压植骨术。

Franchise restrictive competition behavior mostly has six genera embody form, regulation on it, first ought definitude legislative direction idea, secondly ought choose appropriate legislative mode, definitude particularize restrictive competition behavior of be under an embargo in franchising, constitute exempt system of franchising.

The numerical simulation result indicates that the condition of which generated APSGD is that the AC voltage frequency is 9kHz when the electrodes configuration is determinate and the sinusoidal peak-to-peak applied voltage is about 9kV. When the AC voltage frequency is about 1MHz, the discharge pattern of SDBD is filament discharge. This results is very important for the development of SDBD.

从数值模拟的结果来看，在确定的发生器电极结构下，当电压的峰-峰值电压为9kV时，发生沿面辉光的条件是电压频率至少为9kHz，而当频率为1MHz时，沿面放电将出现丝状放电的模式，因而这一模拟结果对沿面放电发生器的研制有很重要的指导意义。

The authors begin with reducing personal error, conclude personal errors during digitize and point out corresponding correct methods. At the same time, a new method is advanced to check out DEM errors quickly. To some degree, the article can conduct the production.

China's real estate industry has lagged far behind the construction of early warning system difficult for the Government to carry out "pre-conditioning", it is necessary to establish a nationwide real estate market and improve early warning systems, regularly published by the Government land and housing prices of the macro-guidance, if necessary should be provided for the lowest price and the price for the land and residential investment and development to provide price information for reference, so that the regulation of the received good results.

中国的房地产行业已远远落后于建设的早期预警系统政府很难进行"预处理"，有必要建立一个全国性的房地产市场，提高早期预警系统，定期公布政府的土地和住房价格的宏观指导，必要时应当提供最低的价格和土地价格和住宅投资和发展提供价格信息，以供参考，以便调节收到很好的效果。

The main usefulness of the tourist area life cycle is to seek common regular issue on space trend of tourist development. It is not a long time for the theory coming into being. It contributes to describing and forecasting the developing track of tourist area and to guidance the plan.

Four research results in the research are provided on the basis of wholly absorbed attention behavior performance including eyes-gazing, concentration as well as completion of orders, attention-testing performance, and multiple attention-testing performance. The collected materials are analyzed throughvisual analyze and Tryon's C statistic. The results of this research are as follows: 1. Attention-training maintains and give rise to samples' attention behavior. 2. Attention-training makes samples' attention-testing performance better. 3. Attention-training has generalization effects on samples' self-instruction and strategies for monitoring and behavior. 4. Attention-training has different effects on samples of different genders.

本研究以专心注意行为表现、自编注意力测验表现、多向度注意力测验表现及班级教师访谈问卷四项结果作为依据，所得的资料以目视分析法及C统计进行分析，所得研究结果如下：一、三位受试者之C统计值达显著(P1.65)，显示注意力训练对受试者的专心注意行为具有提升与维持效果；二、三位受试者在四项分测验中，有三项测验之C统计值达显著(P1.65)，显示注意力训练对受试者在注意力测验的注意力表现具有提升效果；三、由班级教师访谈问卷分析中得知注意力训练对受试者的自我指导、监控策略与行为具有迁移效果；四、由自编注意力测验结果分析显示，注意力训练对不同性别学生能显现不同的训练效果。
