  • ba : Ba ＝ 【化學】元素鋇 （barium 的符號）。n. 【埃及神話】魂靈〈被古埃及人描述成人頭鳥身，死時飛離肉體，以後又要飛回，所以要保存屍體〉。
  1. Surface states and the topmost surface atoms of the batio3 thin films have been analyzed by x - ray photoelectron spectroscopy ( xps ) and angle - resolved x - ray photoelectron spectroscopy ( arxps ). the results show that the as - grown batio3 thin films have an enriched - bao nonstoichiometric surface layer which can be removed by ar + ion sputtering, and the atomic ratio of ba to ti decreases with increasing the depth of ar + ion sputtering

    用x射線光電子能譜技術（ xps ）和角分辨x射線光電子能譜技術（ arxps ）研究了薄膜的表面化學態以及最頂層原子種類和分佈狀況，結果顯示在熱處理過程中薄膜表面形成一層富含bao的非計量鈦氧化物層，並且鋇-鈦原子濃度比隨著探測深度的增大而逐漸減小。
  2. The amounts of salmonella were 1. 3 x 108cfu / ml after 20 hours in co - culturing with bi. when four strains supernatants and acetic acid - lactic acid ( 3 : 2 ) of ph4 were added to broth media to culture salmonella, it was found that the inhibitory ability of acetic acid - lactic acid was the highest, then was that of ba, bl and bbr supernatants, and the inhibitory ability of bi supernatant was the lowest

    將ph值接近4的四株菌的上清液和0 . 1m 、 ph4的乙酸-乳酸（ 3 ： 2 ）混合酸液以一定比例加入培養基中，培養沙門氏菌，發現酸液對沙門氏菌的抑制作用最強： ba 、 bl和bbr上清液的抑制強度相近，但不及酸液； bi上清液的抑制作用最差。
  3. The study on the dielectric properties of ba zrxti1 - x o3 relaxor ferroelectric

    3弛豫鐵電體的介電性能研究
  4. The results showed that the interplanar spacing d values and relative x - ray diffraction intensity of the mixed lb films change with the ratio of ba / sa in a step - and w - shaped curve respectively, which indicates that only three kinds of longitudinal periodic structures can form in the mixed multilayer lb films of all ratios and each microstructure can be maintained in a certain ratio range. furthermore the mixed system always goes through a process of the longitudinal regularity decreasing when the ratio of ba / sa is out of the intermediate ratio range ( ba / sa : 1 / 5 ~ 1 / 1 )

    結果發現，對于sa ba混合膜，分相小而均勻，不出現單獨的衍射周期；隨比例不同，縱向面間距出現臺階效應，表明存在3類結構，其中在較大比例范圍內出現了長短鏈交錯的結構，這種結構具有高的穩定性和有序性；在ba較多的混合膜中，在脂鏈層間出現空洞結構，可以用來構造特殊的納米結構。
  5. Based on this, the abstract of my work is shown following : 1. x - ray diffraction ( xrd ) technique was used to investigate the phase - separation and microstructure of the ba / sa mixed multilayers

    本論文涉及到以下幾個方面的工作： 1 、用xrd和原子力顯微鏡的接觸模式研究了不同ba sa配比的21層混合lb膜的分相和微結構以及膜的質量。
  6. ( 5 ) by means of xps and edax, the relationship between the composition concentration x of ba1 _ xsrxmoo4 and ba1. xsrxwo4 thin films and sr / ba in the starting electrolytes was researched in some detail, and the x is consistent with the percentage of sr element in the starting electrolytes, so, the composition concentration x can be controlled by modulating the sr / ba in the starting electrolytes. ( 6 ) at room temperature, the photoluminescence properties of as - grown molybdate

    （ 5 ）首次綜合運用珊s和edax等手段分析研究了bal峨sr元moq和bal一srxwo4固溶體薄膜中的組分含量x與初始電解液中s祀a的關系，制備的bal一srxmoq和bal一srxwo4固溶體薄膜中的組分含量x與初始電解液中sr元素的原子百分比基本一致，可以通過調節初始電解液的s心a來控制制備的薄膜中的組分含量x 。
  7. As one of magnetism properties in the magnetism materials, magnetoresistance ( mr ) effect shows the magnitude about resistivity dependence of the magnetic field. the time when people focus on magnetoresistance effect is the last ten years. after mr effect was discovered from the multilayered films fe / co by baibich et al in 1988, helmolt et al got the same result from la _ ( 2 3 ) ba _ ( 1 3 ) mno _ x films

    人們對磁電阻效應的研究主要在於最近的十年間，繼1988年baibich等人在磁性多層膜fe co中發現了磁電阻效應后， 1993年helmolt等人在la _ （ 2 3 ） ba _ （ 1 3 ） mno _ x等鑭錳氧化物薄膜材料中也發現了磁電阻效應。
