集中

Although not technically unrealizable FTTH difficult, but to make FTTH towards success is worth paying attention to the following areas : research and development efforts should focus on the characteristics of new devices and meet FTTH core chip, lowering the cost of optoelectronic devices and passive components; Development of low-cost, easy to install indoor fiber, cable and connector alignment of the construction equipment and tools; Development of high density, easy-to-use fiber patch panel; focus on the development of remote monitoring and management technologies and systems.

FTTH虽然没有技术上不可实现的难点，但要使FTTH走向成功，以下方面值得重视并应集中力量攻关：开发适应FTTH特点的新型器件和核心控制芯片，降低光电器件和无源器件的成本；开发低成本、易安装的室内光纤、光缆和连接器及相配合的施工仪器工具；开发高密度、易操作的光纤配线架；开发集中的远程监视和管理技术及系统等。

免疫组织化学结果显示：13-NT和NOS：与正常视网膜相比，8周糖尿病大鼠视网膜中，INL的3-NT和iNOS免疫阳性细胞明显增多，INL和血管内皮层的eNOS阳性细胞明显减少，INL的nNOS阳性细胞也明显减少；2ET及ETR：与正常视网膜相比，8周糖尿病大鼠视网膜中，ET、ETRA、ETRB免疫阳性细胞明显增多，增多的阳性细胞主要集中于INL，而在血管内皮层增多不明显；3α-synuclein：与正常视网膜相比，8周糖尿病大鼠视网膜中，α-synuclein免疫阳性细胞明显增多，增多的阳性细胞主要集中于视网膜视锥视杆层。

The three groups were loaded and analyzed under the same loading according to the mean value of the bite force of incisors. RESULTS:(1)The maximum stress of dentin in group A was twice higher than that in group B. The maximum primary stress, minimum primary stress and maximum shear stress of group A were respectively 236.35, 228.83 and 218.05 percent of those in group B. The difference of maximum stress values of group B and group C was neglectable.(2) The maximum stress distribution of dentin in group A and group B was quite different (the stress was concentrated in labial and lingual side of the cervical dentin in group A, otherwise in group B it was concentrated in the area around the alveolar and the labial and lingual side of the dentin which was opposite to the tip of the cast metal post and core). The maximum stress distribution of dentin in group A and group B was almost the same.

As a whole, the rocks from diorite enclaves, through quartz-diorite, granodiorite to monzonitic granite, have the feature of REE slightly increasing, Eu from weakly positive transits to negative anomaly, but the diorite enclaves which has Eu negative anomaly. Besides, the Ba, Nb, Ta, P and Ti all show negative anomaly, and have positive anomalies of K and Th, simultaneously, there exists Sr positive anomaly in some rocks. Along with the increasing of the SiO〓, the P and Ti have negative anomaly, Th and K positive anomaly are obvious.
