The case selected is the successful practice about typical technology import of internal combustion locomotive, electric locomotive, and diesel engine, owned by Dalian Locomotive and Rolling Stock Ltd Company of CRRC. Based on analysis, it can be found that firms＇organizational inertia exhibits primarily negative effects, positive effects and a combination of positive and negative effects in different stages of imitative, improved and indigenous innovation respectively. Further analysis of typical events shows that explorative learning mitigates organizational inertia＇s negative effects, while exploitative learning enhances its positive effects. From the angle of organizational inertia＇s effects, this paper deepens understanding on the mechanism of transition from technology importation to indigenous innovation, and provides inspirations for late-coming firms to break the vieious cycle where technology importation leads to more backwardness..展开更多

A coMPact ceramic layer of more than 130 μm was developed on the movable endplate with the hardness up to HV1000 by means of microarc oxidation. A trial of tests conducted in a water power transmission system show that the maximum outlet pressure of the gear pump with the movable endplate treated by microarc oxidation, can reach 16 MPa. It is pointed out that the ceramic coating developed by microarc oxidation technology on the surface of aluminium alloy, is economical and feasible.展开更多
