The atomic ratio of zn / se was close to 1 : 1 , which showed that the znse epilayers had good stoichiometry Znse薄膜中zn se原子比都接近1 : 1 ,制備的znse薄膜具有較好的化學(xué)計量比。
Standard test method for the determination of uranium by ignition and the oxygen to uranium atomic ratio of nuclear grade uranium dioxide powders and pellets 用點(diǎn)火和核級二氧化鈾粉末和顆粒的氧鈾原子比測定鈾的標(biāo)準(zhǔn)試驗(yàn)方法
The xrf analysis of plct thin films shows that the atomic ratio of plct thin films is closed the ideal chemical mole ratio of plct thin films 利用xrf分析了plct薄膜的pb 、 la 、 ca 、 ti原子百分比,可以看出其比例接近于設(shè)計的化學(xué)式摩爾比。
Abstract : based on the principle of non - weighting determination of c 、 h 、 n atomic ratio , a micro - injection sample introducing method was developed for determination of h / c ratio for volatile reagent 文摘:根據(jù)不稱重法測定化合物碳、氫、氮原子比的理論,建立了微量注射法測定強(qiáng)揮發(fā)性液體樣品的氫/碳原子比的方法。
The surface elemental analysis shows that al / o atomic ratio change from about 2 / 3 of not wetted part to about 1 / 1 of wetted part . the damage of coating surface seems to be related to the interaction of outside layer with liquid pb - 17li and thermal stress during heating sample 未浸潤表面的ai / o原子比約為2 / 3 ,浸潤表面約為1 / 1 ,表明液態(tài)鉛鋰合金對滲鋁層表面的al2o3薄層造成了損傷。
