The end of 2007, the company works to professional cleaning service to be extended, with mechanical cleaning technology, central air conditioning cleansing purification project, the robot air duct cleaning, washing of the widely used chemicals, petroleum, petrochemical, oil tank, metallurgical, power, Light industry, printing and dyeing, paper making industries such as equipment boiler, heat exchange, condenser, compressor, ammonia cooler, Air Preheater, equipment Jacket, central air conditioning, heating systems portfolio, and large complete sets of equipment, etc.

07年底，公司业务向专业清洗工程服务扩展、拥有机械清洗技术、中央空调清洗净化工程、机器人风管清洗等，清洗范围广泛应用于化工、石油、石油化工、储油罐、冶金、电力、轻工、印染、造纸等行业的设备（锅炉、热换器、冷凝器、空压机、氨冷机、空预器、设备夹套、中央空调、采暖组合系统、大型成套装置等）清洗和中央空调系统的清洗。

It was illuminated that the width of the centre bright fringe decreased along with the increasing width of the rectangular aperture when the effect of the aperture on the beam couldn't be ignored,however,the width of centre bright fringe step changed with increase of the size of the aperture when the effect could be ignorable,the width of the half maximum intensity of the centre bright fringe decreased along with the accretion of the width of the aperture and then it tends to a constant.

结果表明，当光阑对光束的衍射影响明显时，光束衍射场的中央亮条纹的宽度随着光阑边长的增大而减小；当光阑对光束的衍射影响极小时，中央亮条纹的宽度随着光阑边长的增加而阶跃变化，中央亮条纹强度的半最大值宽度随着光阑边长的增大而减小；当光阑对光束衍射影响极小时，中央亮条纹半最大值宽度趋近于一定值。

Based on the analysis of planting site of median strip in Taiyuan Jiuguan Expresswayt the afforestation species selection principle , procedure and species are determined.

通过对太旧高速公路中央分隔带绿化立地条件研究分析，确定了太旧高速公路中央分隔带绿化树种的选择原则、程序、品种，并对太旧高速公路中央分隔带的绿化提出建

Results: the positive cells mostly included ependymal cells of myelocoele, glial cells, anterior horn motor neurons, and epithelial cells of spinal pia mater and their expressions were mainly located on cell membrane. interestingly, aqp4 distribution in glial cells and ependymal cells showed certain directivity, but the former was mainly in the membrane side contacting with capillary endothelial cells and the latter mostly in the basolateral membrane of ependymal cells.

结果： 免疫组织化学染色和原位杂交结果显示胶质细胞、前角运动神经元、中央管室管膜细胞、软脊膜上皮细胞均表达阳性，aqp4主要分布于细胞膜，其中，胶质细胞和中央管室管膜细胞表达存在极性，前者主要分布在与毛细血管内皮细胞接触的一侧，后者主要分布在中央管室管膜细胞的基底侧膜。

CCTV slave station grows Sun Yusheng to say: This is the hour that the CCTV reports to milepost sense is had on the history of the Olympic Games, because this is CCTV first time,be the same as international Olympic committee to counterpoise with respect to independent hookup directly come to an agreement.

Photonic quantum-well structures can be constructed by stacking 3 photonic crystals with the same photonic band gap and different defect modes. On condition that the defect mode of the PC in the well region is located into nontransmission frequency ranges of the PCs in the barrier regions, the confined photonic state appears and can completely transmit through the structure by tunneling. However, its transmission will be strongly prohibited due to vanishing of the photonic QW induced by shifting the defect mode frequency of either of the PCs in the surrounded regions to that of the middle PC.

把三块各带有一个缺陷的光子晶体结合起来，如果中央晶体的缺陷模处在两侧晶体的禁带中，缺陷模内的光波会受到两侧晶体的阻碍并被局域在中央晶体内，形成量子阱结构；若一侧晶体的缺陷模被移动到中央晶体缺陷模处，则只有一侧晶体阻碍在中央晶体缺陷模内传播的光波，量子阱效应完全消失，光的传输受到最大程度的阻碍。

Results: It indicated that compared with the one character naming task, the brain activation regions were smaller and more concentrated in three character naming task, and more deactivation was appeared in the left pericentral gyrus, right precentral and postcentral gyrus, left superior temporal gyrus and right putamen.

结果：与单字命名条件相比，三字命名条件下的脑激活范围更小、更集中。而且，三字命名条件在左侧中央旁回、右侧中央前回和中央后回、左侧颞上回以及右侧壳核出现了更强的负激活。
