  1. However, the refractive index will increase with the increase of the flow ratio of sifu / nhs, slightly increase with the increase of substrate temperate, and decrease with the increase of rf power. by measuring the passivation results of hydrogen plasma and sinx thin film, we found an evident improvement of minor carrier lifetime in polycrystalline silicon after hydrogen plasma treatment, although it has little to do with the annealing temperature and time. the hydrogen contained in sinx thin film can enhance the carrier mobility of monocrystalline silicon, but after annealing at high temperature the mobility turns down

    通過測試氫等離子體鈍化和氮化硅薄膜鈍化的效果,實驗還發現氫等離子體處理對多晶硅材料的少子壽命提高作用比較明顯,但是這種提高作用與處理溫度以浙江大學碩士學位論文王曉泉2003年5月及時間的關系不大;氨化硅薄膜中的氫對單晶硅的載流子遷移率提高有一定作用,但經過高溫處理后這種作用消失;氮化硅薄膜能提高單晶硅和多晶硅的少子壽命,具有表面鈍化和體鈍化的雙重作用;氫等離子體和氮化硅薄膜都能有效地提高單晶和多晶電池的短路電流密度,進而使電池效率有不同程度(絕對轉換效率0
  2. Much works has been distributed to the development of a vacuum system to simulate the outer space and a measurement system to test the arcjet performance. ignition experiments in various operational modes have been done with argon as propellant. macroscopical working parameters including thrust, mass flow rate, voltage, current, inlet pressure and vacuity are obtained by the test measurement system and actual performance parameters including specific impulse, thrust efficiency, ratio of thrust and power and ratio of power and mass flow are calculated

    以氬氣作為推進劑,在不同工況下進行點火實驗,測量獲得了其工作推力、電弧電壓和電流、推進劑流率和弧室壓力等宏觀參數,得到了不同實驗條件下其工作的實際比沖、推力效率、推力/功率比以及比功率等性能參數,分析了推進劑質量流率、電弧功率、電弧加熱發動機電弧室結構尺寸等因素對其性能的影響,為數值模擬研究和實際的低功率電弧加熱發動機優化設計及研製提供了實驗基礎。
