Service innovation involves service concept innovation, service process innovation and clients interface innovation. Because service innovation is more fargoing and requests much intenser interaction with clients than technology innovation, it has more informal or temporary innovation organizations that have self-management control mechanism and exoteric boundary.

服务创新包括概念、过程和界面创新等内容,与技术创新相比,服务创新的范畴更广,同时也有更高的顾客互动要求,反应到创新组织形式上,为非正式化程度高,多以项目团队形式存在等;反应到结构上,则为控制机制的自我监管化,互动界面的开放化、延伸化等。

Therefore, enough consideration should be paid to the effect on Isolation Bridge of the long-term pulse shock while isolation technology is used near faultage. Otherwise, the collisions between beams or the drop of beams will easily occur.

在长周期脉冲型地震作用下,桥梁的地震反应与频谱丰富的一般地震作用有很大区别,减隔震技术的优势已非常不明显,其位移反应相当大。

4Complications:After operation peritonitis appeared in 5cases,among which were 2of intestinal obstruction,and 1 necrosis of left hemicolon.Conclusion:The chemotherapy of selective arterial drug perfusion before an operation reduce the tumor and stiumulate inflammatory reaction and fibroplastic proliferation around it.Thus increases excision rate as well as decreases local recurrence rate and possiblity of cancer merastasis.However,it also leads to some toxic side reaction and possible intestinal obstruction and necrosis.

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.
