Results C/EBPαand C/EBPβexpressed differently in the outer root sheath,follicular papilla,hair matrix and sebaceous gland in embryonic period.The positive signals were chiefly distributed in the nucleˉuses.The expression of C/EBPαand C/EBPβwere found in the basal cell layer of outer root sheath and sebaceous gland in the new born and maturation phase,The expression in nucleuses of outer root sheat cells decreased with the differentiation but enhanced oppositely in the cytoplasm.

结果 C/EBPα和C/EBPβ分别在胚胎期毛囊外根鞘，毛乳头，毛母质及皮脂腺细胞的胞核内强表达；新生儿毛囊峡部下端外根鞘基底层细胞的胞核内也存在强表达，基底内层胞核阳性信号逐渐减弱；而成体毛囊核内阳性信号仅定位于峡部下端外根鞘基底层及皮脂腺基底层。

Using nearly 50 years of landuse classification map of urban center in Shanghai city as data resources,the gross variation of landuse is studied by using GIS technology.Suppotred by GIS,the status transfer matrix of different landuse classification of adjacent period of time is also calculated respectively by this paper.At last,the spatial evolving process of landuse of urban center in Shanghai city is analyzed simulatively and forcasted quantitatively by using Markov model.

以上海市中心城区近50年来有代表性的土地利用类型图为数据源，采用GIS技术分析了上海市近50年来的土地利用总量变化；并在GIS支持下分别计算出相邻时间点不同土地利用类型的状态转移矩阵，利用马尔可夫模型对上海市中心城区土地利用空间演变过程进行了模拟分析和定量预测研究。

In both sampling period and fractal computing dimension,the signal is fuzzed to construct fractal dimension subordinating degree. A novel correct method,the fuzzy neural network diagnosis method,was proposed,in which the input is the fractal dimension subordinating degree, and the output is the unit matrix. A gearing system was diagnosed by using the modeling.

以多时间尺度采样所获得的分形维数隶属度作为网络输入，单位矩阵为网络输出的分形模糊神经网络，建立了时域精确诊断新方法，通过对典型齿轮系统故障进行精确诊断，结果表明分形模糊神经网络诊断方法的有效性。

To help improve Henan Netcom Company's ability of competition, we also make the environmental analysis, the strategy analysis and the competitive analysis; distinct it's external internal strength as well as weakness opportunity, threat. We assure that the core competition abilities include advanced telecommunication network, large numbers of subscribers and various services. Then this text analysis the competitors, the potential competitors, substitutions, equipment providers and customers by using Porter theory, compare each competitor's ability and the field that they compete drastically. Through conforming the costumer's utilitarian and personal services requirement, it discover that the key factor of development is holding the group subscribers. By Boston Matrix we find out key services, staring services, problem services, then study which service is the most important for us and which one should be throw off. Base on analysis above, this article concludes the general strategy and the service strategy of Henan Netcom: enforce the stable development strategy for certain period, and perform expansion strategy when time is fit.
