中文拼音 [zǔkànghěndī]
阻抗很低
英文
low esr-
We have made three - dimension electric conduct grid by hand and we have successfully used it as anode grid in lead - acid battery. this kind of three - dimension electric conduct grid can improve the utilization of pam by 7 - 9 % in different discharge current density and can reduce the plate electrochemical impedance to one tenth of the normal plate. also this kind of grid can improve the marginal reaction current density in a certain degree
我們通過手工製作了三維導電體板柵，並成功的應用於電池的正極作為正極的板柵，這種三維導電體板柵能夠在各種不同的放電電流密度下提高正極活性物質利用率7 9 ，能夠使電池正極板的電化學阻抗降低到普通板柵的1 10左右，使正極板的極哈爾濱j _程大學碩十學位論文限反應電流密度略有所提高，但是這種板柵的耐腐蝕性能很不理想，使得所製作電池的壽命很短。And we also know that we should avoid reducing preload in these patients because reducing preload may cause obstruction of left ventricular outflow tract which is not convenient, so we try to avoid diuretics and nitrates in this kind of patients, but we use calcium antagonists and
我們也知道我們應該避免減低這些患者的前負荷，因為減低前負荷會使本來就很艱難的左心室流出道更加容易阻塞，所以我們都會盡量避免給這類患者使用利尿劑和硝酸酯類藥物，但我們經常會用到鈣離子拮抗劑和The research on the rf characteristics of the conductor - centered helical groove sws. ( a ) in the " cold " system, we found that the changing of depth of the groove has no distinct effects on the phase velocity at the lower frequency region ; but with the increasing of the frequency, the phase velocity and bandwidth are reduced slightly, the structure is more dispersive and the coupling impedance is enhanced
對具有中心導體軸的矩形螺旋槽慢波系統的高頻特性進行了理論研究： （ 1 ）在冷系統中的研究結果表明：頻率較低時，槽深的改變對相速的影響不是很大，隨著頻率的增大相速略有減小，同時帶寬也有所減小，色散變得稍強，耦合阻抗增大。
