However , the result of the simulation , in which all the parameters are kept constant except the primary and secondary inductance , is that 3 % higher conversion efficiency can be achieved in ccm than in dcm 但对输出功率和绕组电阻相同时逆变电路仿真结果表明， ccm的效率比dcm提高了三个百分点；试验结果说明尽管ccm的绕组电阻比dcm的大，变换器效率仍提高了1 . 5 。
Such a structure ? a semiconductor with a disk cut out of it , which squeezes the current through the two narrow channels of semiconductor ? has a much higher resistance than an uninterrupted slab of semiconductor ( which itself has higher resistance than a semiconductor with a disk of metal embedded in it ) 这种在半导体中挖个圆洞，把电流压缩到两旁狭窄通道的结构，其电阻比起没有障碍的半导体薄片要大很多（不过后者的电阻又比有金属圆盘的半导体来得高） 。
We adopt new production process of cold ends , so our sic heating elements have excellent specific rate of heat zone resistance and cold end resistance , saving energy , long life , avoiding over - temperature of cold ends to damage the furnace body . the commercial name of our sic heating elements is songshan silca heating elements 我们的碳化硅电热元件采用新的冷端部生产工艺，具有优良的热冷端电阻比，节能、寿命长，同时避免了因冷端部温度过高对炉体造成的损害。
It shows that the charge - discharge performance of the battery , which is fabricated by casting the polymer electrolytes on the surface of the cathode directly then impregnating the composite electrode in liquid electrolytes for seconds , is much better than that of other batteries . the best battery ， s charge - discharge current density is as high as 0 . 33 ma / cm2 , and its specific energy accesses to 110ah / kg . moreover its capacity remains 80 % of initial capacity even after 20 cycles 这种电池的充放电电流密度可达到0 . 33ma / cm2 ,比容量可达110ah / kg ,且在20次循环后,电池的容量仍能保持初始容量的80 % ，电池的充放电效率达到85 %以上，但是电池的本体电阻和电化学极化电阻比液态锂离子电池高两个数量级。
Through study on the electrical performance of sn - in2o3 nano powder , some conclusions were drawn . when sn - in2o3 precursor was calcinated at 700 - 1000 , low square resistance was got . the resistance was lower when sn - in2o3 precursor was calcinated in vacuum than air condition Sn - in _ 2o _ 3纳米粉体的电性能研究表明： sn - in _ 2o _ 3前驱物在700 - 1000煅烧，方块电阻较低，真空条件下煅烧试样的电阻比空气条件下煅烧试样的电阻低，南京工业大学硕士学位论文中文摘要sno :掺杂10wt %左右时，试样方块电阻最低。
