As these methods exist shortages, advanced diagnosis strategy is presented, which combines the fuzzy neural network instead of fuzzy inference to rules inference. the problem of accuracy ratio decline because of roughness of fuzzy synthesizing algorithm has been solved. an example of car diagnosis is given and validity of this method has been proved
因此本章提出了以模糊神經網路代替模糊推理並與規則推理相結合的先進診斷策略，解決了因模糊合成演算法的粗糙性使診斷成功率下降或診斷錯誤的問題，並給出了一個車輛故障診斷實例，驗證了上述方法的正確性和有效性。 -
Both the tide and the increase of floodplains " roughness can change the diffluence ratio between northern and southern branch
外海潮波和灘地糙率的變化可以影響南北兩汊河道的分流比。 -
Based on the above numerical procedure, parameter study, including the vehicle velocity, damping of the bridge, road surface roughness, and constrained freedom of the bridge, is conducted to investigate the influence of some important bridge and vehicle parameters on the impact ratio of the bridge
基於上述方法，本文深入分析若干物理參數包括車速、橋梁阻尼、路面平整度和橋梁約束條件等對橋梁沖擊系數的影響。 -
It is validated that the numerical methods can absolutely predict the flow in the microchannels. the flow field around the roughness and the pressure drop of midline along flow direction are analyzed. it ' s found that the range of the pressure drop change relate to the magnitude of relative roughness, the distance between two parallel planes, the re number and ratio of the size of roughness and the distance between two roughness
通過對粗糙元周圍流場和充分發展段中心線壓力曲線的分析，發現有粗糙元存在的兩平行平板間微通道，其充分發展段壓降大於光滑平板充分發展段壓降；當相對粗糙度和re不變時，隨著板間距的減小，粗糙度對主流的影響不斷增大；當板間距和相對粗糙度不變時，在層流狀態下，粗糙度對流動的影響不隨re的變化而變化；當板間距和re保持不變時，相對粗糙度越大，其對流動的影響就越大。 -
With the favor of these techniques, the static pressure distribution along the length and the velocity profile at the mini - channel exit were obtained. with the data of more than 500 flow states based on 13 kinds of mini straight rectangular channels that their heights were 0. 5mm and 1. 0mm, the effects of characteristic scale, surface roughness and the aspect ratio of rectangular on the characteristics of flow resistance of mini straight channels were studied
採用在沿程測量氣流靜壓分佈、在出口測量速度分佈的方法，對高度0 . 5mm和1 . 0mm的13個微小直矩形通道的500多個狀態流場進行了測量，研究了特徵尺度、表面粗糙度、橫截面寬高比等因素對微小等直通道流動阻力特性的影響。 -
