結果表明40km距離處,目標與背景在光電探測器上的輻照度信噪比大於可探測最小信噪比;目標在探測器靶面上的輻照度滿足探測器所能探測到的輻照度最小值;實驗數據上推導出系統的作用距離能達到這一指標。The results of simulations are : i ) energies of the incident ions to the target are determined mainly by the voltage across the cathode sheath, with a majority of ions " energy vary around the sheath voltage ; ions nearly normally bombard the target ; ions mainly locate above the sputtering holes because of the influence of the magnetic field, and the incident ions mainly come from the region ; the ions undergo several collisions during transportation, but that do n ' t matter much
主要模擬結果有: ? )入射離子到達靶面時的能量主要受到了射頻輝光放電中陰極殼層西北工業大學碩士學位論文李陽平電壓的影響,大部分離子的入射能量在陰極殼層電壓值附近,離子濺射時接近於垂直入射;射頻輝光放電受到陰極磁場的影響,等離子體中的離子主要集中在靶面濺射坑的上方,且入射離子主要來自這個區域;入射離子在輸運過程中和背景氣體分子有少量的碰撞,但影響不太大。Many measures were adopted to decrease bombard in order to improve the solar cells propertivity, such as decreasing target voltage, increasing target distance, accelerating the movement of the substrate. by optimizing the experimental conditions, short - circuit current was increased by 3. 7ma / cm2, the conversion efficiency was increased by 2 %, the stability was improved
在硅薄膜電池的zno : al al背反射電極應用方面,通過減小靶電壓、適當增加靶距和基片的運行速度來減小對電池的轟擊,改善電池性能,通過優化實驗條件,使電池的短路電流提升了3 . 7ma cm ~ 2 ,效率增加了2 ,穩定性得到改善。When targets penetrated by flat - ended projectile, shear deformation along the penetration direction appears, at the same time compressive deformation also appears in the material that is in front of the projectile. the compressive deformation begins at the back surface of the target and spreads inward
鈍頭彈侵徹下,側壁材料發生軸向剪切變形,同時,彈體前方的材料發生壓縮變形,壓縮變形首先在靶板背表面開始,而後自背表面向靶內傳播。All of above make the miss distance of the missile difficult to estimate in shooting range. in order to solve these problems, a novel method for detecting and tracking small moving point target in image sequence is proposed in this paper, based on combination of the correlation of multi - frames and wave gate techniques. especially, the qualifications to confirm the target and the establishment of the wave gate based on size and characteristic moving parameters of the target are stressed in the paper
