      基本解釋(剩余方差)

      網絡釋義

      1)residual variance,(剩余方差)2)residual variance,剩余方差3)surplus,remnant,剩4)EX Excess,過剩,剩余5)remanence,剩磁6)residual magnetism,剩磁7)surplus,過剩8)excess,過剩9)surplus,剩余10)residual flux,剩磁

      用法和例句

      The remanence, coercivity and maximum energy product decrease with deteriorated grain alignment.

      計算結果表明,隨著磁體晶粒易軸取向度的變差,磁體的剩磁、矯頑力均隨之下降。

      Metal magnetic powder with fine particles and relative higher coercivity and remanence are ideal materials for high density magnetic recording.

      金屬磁粉顆粒細小,具有較高的矯頑力和剩磁,是較為理想的高密度磁記錄材料。

      In the steel tube nondestructive inspection by using magnetic technique,the steel tube needs to be magnetized,thus the magnetized steel tube has remanence.

      檢測前 ,首先對鋼管磁化 ,然后再進行檢測 ,但是 ,磁化后的鋼管會有剩磁 ,這種剩磁不但給后繼加工 (如螺紋加工、焊接 )、安裝及使用造成不便 ,也會影響儀器設備的正常工作 ,所以 ,檢測后的鋼管必須進行消磁處理。

      It is pointed out that the vibration with main frequency of 50 Hz is greater only in part of this transformer on load, and the switching surge current has maximum value of same kind of transformer, which have the possibility of obvious residual magnetism in this transformer.

      認為該變壓器帶負荷時僅局部區域振動較大,且主頻率為50Hz,變壓器合閘涌流為同類變壓器的最大值,不能排除該變壓器存在明顯剩磁的可能性。

      The closing excitation inrush current was large because the residual magnetism of the transformer was overly large.

      分析認為,引起該變壓器重瓦斯動作的主要原因是較大的合閘勵磁涌流引起主變線圈器身振動所形成的油流擾動,引起該合閘勵磁涌流明顯偏大的原因主要與變壓器的剩磁過大有關,提出了現場控制變壓器剩磁的方法。

      Checking and analysis revealed at last, that it was caused by residual magnetism after repair, the polarity of which was opposite to that effected by direct current in the rofor.

      在水力發電公司檢修時,幾次碰到發電機不能啟勵建壓的情況,經過檢查分析,最終確定為剩磁的原因,主要是檢修后剩磁的極性與轉子直流電產生的極性相反造成的。

      On the Reasons of Macroeconomy Total Output Surplus;

      我國宏觀經濟總體過剩的成因

      Recent years has seen periodic surplus of refining capacity in Asian Pacific region.

      近幾年亞太地區煉油能力出現了階段性過剩 ,預計這一情況將持續到 2 0 0 3年左右。

      In this article,Bruno production function is selected for the two step analysis of the Chinese agricultural output,which has taken the country s surplus labour force and its transfer into full consideration.

      針對中國農村勞動力嚴重過剩的國情,選用Bruno的生產函數,對我國的糧食產量進行了實證分析。

      There is no doubt that Chinese economy has to face a fact------excess liquidity now.

      中國經濟正面臨著“流動性過?!?這是一個讓人不愿面對而又不得不面對的事實。

      Analyzing the transfer of surplus labors in the rural areas of China;

      試析我國農村剩余勞動力的轉移

      The essential difference between the"surplus" of public hospital and enterprise was emphasized.

      強調公立醫院的“剩余”和企業的有本質區別。

      By the principles of economics,the change of consumer surplus,producer surplus and social surplus with railway freight transport integration was disc.

      進一步運用福利經濟學原理 ,分析了鐵路貨運集中化前后消費者剩余、生產者剩余和社會總剩余的變化 ,得出鐵路貨運集中化會使社會總福利增加。

      Considering the effects of residual flux to inrush transient, the grounding resistor connected to the transformer neutral point is used to restrain the inrush transient of the first closeing phase and then a "delayed closing-strategy" is employed to reduce the inrush current ma.

      該方法考慮了剩磁對勵磁涌流的影響,利用中性點串聯電阻的方法抑制首合相勵磁涌流暫態過程,利用“延遲合閘”策略限制剩余兩相涌流幅值。

      Analysis shows that this phenomenon is caused by the residual flux in step-up transformer.

      采用變頻起動的大型同步電機在起動初期可能出現反轉現象 ,這對有些被驅動設備是不允許的 ,經分析這種反轉現象是由升壓變壓器的剩磁引起的 ,通過消磁的方法解決了這一問題。

      The residual flux in iron core is analyzed too.

      通過有載合閘變壓器模型,分析了變壓器有載合閘過程中由于副邊突然短路導致主保護動作時電流和磁通的暫態過程,并對變壓器鐵心內的剩磁作了定性的分析。
