The smaller bismuth ruthenate partical is, sheet resistivity is lower and temperature coefficient of resistance is more positive and the refiring change ratio is nearer to zero.

鉛硼硅玻璃粉體平均粒徑對厚膜電阻的性能影響有一極值點国产精品久不卡在线观看蜜，約為1.51μm，在該點處膜層的方阻值最小亚洲国产欧美日韩A片在线观看，電阻溫度系數(shù)絕對值最小亚洲色图偷，重燒變化率最接近零值亚洲国产欧美日韩AⅤ。

This paper also make research on the influence of heat treatment technology on the resistance and TCR of different thick film elements including Ag-Pd, bismuth ruthenate and copper ruthenate, and influence of heat deposition technology on the consistency of resistance of the elements.

此外，論文研究了熱處理對Ag-Pd国产美女AAA在线、釕酸鉍九九视频精品38在线播放、釕酸銅三種不同材料體系厚膜電阻元件的阻值、電阻溫度系數(shù)的影響和熱存放對電阻元件阻值一致性的影響欧美性交片网站。

In chapter 1, the progress in study of the ruthenium complex oxides. especially the coexistance of magnetism and superconductivity in 〓 and 〓 are introduced. The introduction makes conclusion that all of the Ru-1212 and Ru-1222 compounds reported are accompanied by small amounts of SrRuO〓 impurities, this is to say that, it is difficult to synthesize pure samples of these two compounds by traditional solid state reaction. So the author think that the studies for new synthesis methods of ruthenate superconductors which is beneficial to the synthesis of new type precious metals superconductivity is very important till now.

第一章重點綜述了釕系復(fù)合氧化物的研究進展欧美乱婬视频婬色，特別是其中超導(dǎo)電性的發(fā)現(xiàn)及其釕系1212、1222相銅氧化物超導(dǎo)電性和鐵磁性共存的特征国产乱了真实在线观看一级，在此基礎(chǔ)上可以看出日韩新片免费无码观看视频网站下载，至今文獻報道所獲得的Ru-1212和Ru-1222相化合物都含有少量的SrRuO〓雜相，即很難通過原有的固相反應(yīng)方法得到純相化合物欧美又长又粗性视频，由此作者提出最刺激得黄色网站，現(xiàn)有釕系超導(dǎo)氧化物合成的新方法研究仍具有重要的現(xiàn)實意義，這也將更有利于探索合成新型貴金屬超導(dǎo)體福利网站在线观看。

It was found that, with the increasing of volume fraction of silver and conductor phase, sheet resistivities descend and there are critical thresholds. The average partical size of bismuth ruthenate and PbO-B_2O_3-SiO_2 glass was researched.

研究了各相粉體平均粒徑對膜層性能的影響538在线视频免费播放，結(jié)果表明：釕酸鉍平均粒徑越小，膜層的方阻值越小欧美在线精品大片，電阻溫度系數(shù)偏正久久精品一级无码，重燒變化率越接近零值，球磨工藝的極限平均粒徑為0.56μm先锋影音在线。

PbO-B_2O_3-SiO_2 glass reacts with bismuth ruthenate and lead ruthenate is produced as transition layer. The transition layer can make the interface gradually change and the properties of resistors are improved at the same time. Based on the study above, the way to get series of pastes was developed.

在上述研究工作的基礎(chǔ)上欧美一级一片在线观看，總結(jié)提出Bi_2Ru_2O_7/Ag系厚膜電阻漿料實現(xiàn)阻值系列化的方法：改變功能相中銀的百分含量和漿料固相中功能相的百分含量確定電阻膜層的方阻值和電阻溫度系數(shù)；改變復(fù)合無機粘結(jié)相中兩組元的配比實現(xiàn)厚膜電阻重燒變化率的可控調(diào)整伊人精品视频中文字幕，并對方阻值和電阻溫度系數(shù)進行微調(diào)尤物网站在线视频免费观看。
