Examples

  • The spectral lines emitted from these species can be used to determine the sample composition . the wavelengths observed are characteristic of the individual elements present in the sample , and their intensities are related to the concentration of the corresponding species in the sample
    高功率密度的激光使樣品表面汽化,產(chǎn)生處于激發(fā)態(tài)的原子和離子,而激發(fā)態(tài)原子和離子的發(fā)射譜線可用于樣品成分的鑒定,發(fā)射譜線的強(qiáng)度與該原子對應(yīng)的元素在樣品中的含量有關(guān)。
  • The sample composition was analyzed by means of tg and x - ray diffraction . the following conclusions can be drawn from the experiments : given conditions , the sample powder that has the same xrd data as the standard fetioa can be gotten when use any method mentioned above ; the key in synthesis is to avoid the oxidation of fe2 + , so the whole process should performed under vacuum or neutral atmosphere , samples used by this study were prepared under nitrogen atmosphere ; the heat - treated time and temperature have some influence on the sample powder , results show that the proper time and temperature is 120 minutes and 1100 respectively
    研究結(jié)果表明:在合適的反應(yīng)條件下,用上述三種合成方法都能得到xrd數(shù)據(jù)與標(biāo)準(zhǔn)fetio _ 3物相基本吻合的粉體;合成反應(yīng)需要克服的主要問題是防止體系中fe ~ ( 2 + )的氧化,因此,整個反應(yīng)必須在真空或者非氧化性氣體保護(hù)下進(jìn)行,本研究需要的樣品是在高純從保護(hù)下合成的;煅燒的時間和溫度對最終的產(chǎn)物也有一定的影響,研究發(fā)現(xiàn):合理的煅燒時間和溫度分別為120分鐘和1100 。
