The average partical size of bismuth ruthenate and pbo - b _ 2o _ 3 - sio _ 2 glass was researched. the smaller bismuth ruthenate partical is, sheet resistivity is lower and temperature coefficient of resistance ( tcr ) is more positive and the refiring change ratio is nearer to zero. the limit size of bismuth ruthenate partical is 0. 56 m
研究了各相粉體平均粒徑對膜層性能的影響,結果表明:釕酸鉍平均粒徑越小,膜層的方阻值越小,電阻溫度系數偏正,重燒變化率越接近零值,球磨工藝的極限平均粒徑為0 . 56 m 。4. problem of circular array ’ s high side - lobe ( relative to main - lobe ) and the lower depth of zeros is resolved using mode space transform, which changing uniform
4 .利用模式空間變換將均勻圓形陣列轉化成虛擬的均勻線陣,解決了圓形陣列副瓣電平較高(相對于主瓣) 、零點深度相對較淺的問題。A novel resonant pole zvt three - phase pwm inverter circuit for three - phase ac motor driving is presented. the proposed circuit has the feature of being more flexible with three inverter arms in zvt process. using only one resonant inductance, the inverter can not only reduce the power loss of inductance but also avoid possibility of unbalance in motor ' s three stator windings
提出了一種針對三相交流電機驅動的新型諧振極零電壓過渡三相pwm逆變器電路,該電路中三個逆變橋臂的零電壓過渡更具有靈活性,僅使用一個諧振電感,既減少了電感損耗又防止了電機三相定子繞組可能存在的不平衡問題,並且諧振電感中殘余能量能夠回饋給電源;新型逆變器的輔助開關均工作在零電流開關條件下,並且控制邏輯簡單。Finally, the operation principle of three - level shift phase pwm control with zero voltage is validated by the simulation analyze and the debugging experiment of 230v / 10a sample device
最後,通過模擬分析以及對230v / 10a樣機的調試實驗,驗證了零電壓三電平移相控制pwm三電平直流變換器的工作原理。This dissertation furthers investigate a regional lmmcs formed of scene and middle level emphatically. on the basis of enhanced m - bus and zero power technological, the paper developed corresponding software and hardware products, and took a series of non - electromagnetism interfere ways and the dependability design. put up the platform to simulate spot environment, and carry on the overall experiment to verify : every technical indicator and performance index of long distance multi - point monitoring and controlling system can be satisfied, and the system has very high theory value and practical value
本文重點介紹了長距離多點監控系統在地下管網中的應用實例,對由設備層利控制層構成的地下管網監控系統進行了深入研究和分析設計,基於自主研發的增強型m - bus總線和零功耗設計技術開發了相應的軟硬體產品,採取了一系列抗電磁干擾措施及可靠性設計,並模擬現場環境搭建了平臺,進行了全面的實驗驗證。This paper brings forward that asvg is capable of compensating harmonic, negative sequence and zero sequence currents. so asvg can synchronously compensate the reactive current and harmful currents in three - phase four - wire unbalanced system
本文提出靜止無功發生器還具有抑制諧波和濾除負序、零序電流的能力,從而可以用於對三相四線制不平衡系統同時進行無功補償和有害電流濾除。分享友人
