Investigation on the vector distribution of dengue fever in urban district of xiamen 廈門市區(qū)登革熱病媒分布調查
In addition , in order to guarantee the smoothness of weight vector distribution in output space , mfknn2 method is introduced a smooth factor in the modification of connective weight coefficient between neuron 同時對mfknn2中神經網絡的權值修改還引進一個平滑因子,以保證權矢量在輸出空間分布的平滑性。
In this paper a kind of cardio - cerebral arterial bifurcation vessel hemodynamic characteristics are studied with the boundary element method , and the blood flowing velocity vector distributions have been calculated . in addition , the flow field distribution and the pressure on the particle surface are also calculated , when there is flow - round particle at the place of bifurcation , the move tendency of the particle is judged , the possible reasons of causing the atherosclerosis , thrombus , angioma are analysed 本文用邊界元方法研究了一類典型心腦動脈分支血管中血液流動的流體動力特性,計算了分支血管血液流動的速度矢量分布,同時計算了分支附近有多個顆粒狀繞流物時血液的流場分布,及顆粒物所受壓力狀況,給出了顆粒物的運動趨勢,分析了引起粥樣斑塊病變、血瘤、血栓的可能原因
