  7. We researched the influences of systhesis temperature, heat preservation time, eu + concentration, reduction surrounding feeling and flux on luminescent properties of sral2o4 : eu2 + phosphors, optimized the experiment conditions and reduced systhesis temperature about 100 c. we found that the systhesized sample ' s luminescent brightness is better with increasing systhesis temperature, but the phase component is more complex. we found that the luminescence brightness of sample appear a increasing process at first, and then a reducing one with the raise of eu2 + concentration, it indicated that the luminescence brightness is not better if the eu2 + concentration is too high or low. we found that the systhesized sample can not bright at too long heat preservation time, and the luminescence brightness is lower at too short heat preservation time. we found that particle diameter is bigger, the wavelength of emission peak is longer

    研究發現合成溫度高,合成樣品的發光效果好,但物相組成也較復雜; eu ~ ( 2 + )離子在一定摻雜濃度范圍內,合成樣品的發光亮度先是出現一個提高過程,然後是一個降低過程,說明eu ~ ( 2 + )離子濃度高或低都不利於合成樣品發光;保溫時間較長,合成樣品不發光,保溫時間較短,合成樣品發光效果不好,只有合適的保溫時間才能合成發光效果好的樣品;合成樣品的粒徑大小與發射峰的位置具有一定的關系,粒徑越大,發射峰越偏向長波方向;助熔劑對樣品的合成溫度和發光性能都有影響,助熔劑的量較低時,主要表現為助熔作用,對發光影響不大,助熔劑的量較高時,使得樣品發光亮度降低和余輝時間縮短;還原方式的不同,合成樣品的發光性能也不一樣。
  8. Due to the rapid heating rate, the time for wire stayed in high temperature zone is very short and no enough time for grain grows largely, hence the structure size of continuously induction heated wire is smaller than that of conventional heated wire and grain size is 2 to 4 level higher. due to the fine grain size, the induction heat oil tempered spring wire can acquire more reasonable comprehensive mechanical properties under same strength

    可見,由於加熱快,在高溫停留時間短,組織晶粒來不及長大,因此,連續感應加熱鋼絲的組織晶粒尺寸比一般加熱小,晶粒度高2 - 4級。由於組織晶粒尺寸細小,因此,感應加熱油淬火-回火鋼絲,在同樣強度下,具有更高的綜合b力學性能。
