助熔作用的英文
fluxing action
例句与用法
- 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
研究发现合成温度高，合成样品的发光效果好，但物相组成也较复杂； eu ~ ( 2 + )离子在一定掺杂浓度范围内，合成样品的发光亮度先是出现一个提高过程，然后是一个降低过程，说明eu ~ ( 2 + )离子浓度高或低都不利于合成样品发光；保温时间较长，合成样品不发光，保温时间较短，合成样品发光效果不好，只有合适的保温时间才能合成发光效果好的样品；合成样品的粒径大小与发射峰的位置具有一定的关系，粒径越大，发射峰越偏向长波方向；助熔剂对样品的合成温度和发光性能都有影响，助熔剂的量较低时，主要表现为助熔作用，对发光影响不大，助熔剂的量较高时，使得样品发光亮度降低和余辉时间缩短；还原方式的不同，合成样品的发光性能也不一样。
