查询词典 initial a document

2In order to reduce the randomness of choosing initial centers, this paper puts forward an algorithm of initialing centers called BD which is based on density.

The results confirm that NH3 slip increases with both higher ratio of NH3 to NO n(NH3/n and higher concentration of a reducing reagent, while it decreases with the increase of temperature. Initial NO concentration and its residence time can also affect the NH3 slip. A higher initial NO concentration lead to higher NH3 slip, but added residence time has the opposite effect. Among urea, ammonium carbonate and ammonia liquor, the NH3 slip of urea is the highest and that of ammonia liquor is the lowest.

The proposed robust road main direction detection method consists of initial main direction extraction based on the direction histogram of structure tensor and precise direction detection on vectorized edge image. Experiment results demonstrate its robustness and precise. The proposed Gibbs-sampling-based method models road network with marked point process and can effectively extract road network with initial configuration. However it is slow and still can not deal with single and isolated road segment. These problems can be solved by the real-time method. And experiments verify that the real-time method is fast during extracting road segment.
