超大量衰減 的英文怎麼說
中文拼音 [chāodàliángshuāijiǎn]
超大量衰減
英文
ultrahigh reduction-
The results show that : nano - nickel powder is not useful for mh electrode during the high rate discharge phase as a conductor or additive ; superfine nickel powder is applicable for the conductor of the negative because of the good performance especially the cyclic stability at 1c rate by using 5 % ( mass percentage ) nickel powder ; the utilization of alloy, specific mass and volume capacity are increased with the decreased particle size of nickel powder in negative, however, the capacity fading rate at 1c discharge rate is also increased, so the capacity and the cyclic stability should be taken into account to make a choice of the particle size
結果表明： mh電極中加入納米鎳粉對負極的大電流放電性能不利。 mh電極中加入超細鎳粉后電極綜合性能好，尤其是1c循環穩定性，其最佳添加量為5wt 。減小鎳粉粒度提高了電極合金利用率、質量比容量、體積比容量，但增大了負極1c容量衰減率，因此鎳粉粒度的選擇應綜合考慮mh電極容量和循環穩定性。This paper discusses some problems in supersonic velocity measurement, and expounds, in the form of numerical computation, the availability results about supersonic energy attenuation adapting to distance, as well as the influential factors on the measurement
摘要該文討論了超聲波聲速測量實驗中出現的幾個問題，並通過數值計算，說明了超聲波能量隨距離的增大而形成的衰減趨勢，並對影響測量精度的因素進行了討論。
