  1. The thermal visualizations of jet impingement cooling with single or double row holes inside semi - enclosed channel are measured by using infrared camera and then the impingement cooling heat transfer coefficients are deduced. the effects of flow and geometry parameters on convective heat coefficients are obtained. the results show that : for a single row normal impingement, the impingement cooling effectiveness is enhanced with the increase of impinging reynolds number or the decrease of hole space to diameter ratio, and the best effectiveness is achieved under the jet - to - surface spacing equals to 2 ; when the jet is oblique to the confined wall, the cooling effectiveness is weaken especially under the jet - to - surface spacing ratio is greater than 2 ; for double rows normal impingement cooling, the cooling effectiveness of rear row jet is weaker than the front row under lower impinging reynolds number or bigger jet - to - surface spacing

    對于單排垂直流,沖擊冷卻效果隨流雷諾數的增加、孔間距與直徑比的減小而得到提高,沖擊間距比為2時換熱效果最好;沖擊孔中心向通道封閉一側后,流沖擊冷卻的范圍變窄,當沖擊間距比大於2時駐點區的對流換熱能力明顯降低;對于雙排沖擊流,孔排間距與直徑比的增加使沖擊冷卻范圍變大,但在兩排孔之間區域的對流換熱系數有所下降;在較小的沖擊流雷諾數和較大的沖擊間距比下,後排流的沖擊換熱效果要遜於前排流。
  2. Through the theory of light radiation and intensity, we can use the fewest leds to satisfy the luminous intensity demand. through image segmentation theory, we can accurately pick module up from the test stripe when it is put in wrong directions. through image processing theory, we can acquire correct information and avoid the bad effects from the asymmetric chemistry reaction and instability of the devices

    用光的輻和強度理論,我們計算出了獲得足夠圖像強度所需的最少光源;用圖像分割理論,我們在試紙條放置或有垂直方向上的偏移時,準確地提取出了各模塊的數據;用平滑濾波和均值濾波理論,我們濾除了由於反應不均勻及硬體設備不穩定帶來的噪聲;用交遇區設計性分類器的方法,我們降低了有限樣本設計性分類器帶來的誤差,提高了檢驗準確度。
