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

Based on the experimental data, the mean overtopping discharges of perforated and nonperforated caissons are compared. It is found that when the relative crest freeboard is smaller than 1.6, the mean overtopping discharge of a breakwater can be reduced by at least half by using perforated caissons with 35% porosity instead of nonperforated caissons. The effects of the relative crest freeboard, the caisson porosity and perforation shape, the relative wave chamber width and the relative water depth on the mean overtopping discharge at perforated caissons are clarified. Then,predictive formulas for the mean overtopping discharge at perforated caissons are developed. The predictive formulas based on the experimental data are valid in a wide range of the relative crest freeboard and involve the effects of the caisson porosity and the relative water depth. The predictive formulas developed in this study are of significance for the hydraulic design of perforated caissons.展开更多
