在英语句子里,要使句子的某一部分显得更加重要,往往采用复复的方法来加重语气,或加强意义,常见的重复用法有以下几种: 1.反复使用同一个词 1)She looks much,much older now than before. 她看起来比以前老得多的多了。 2)He is a man ...在英语句子里,要使句子的某一部分显得更加重要,往往采用复复的方法来加重语气,或加强意义,常见的重复用法有以下几种: 1.反复使用同一个词 1)She looks much,much older now than before. 她看起来比以前老得多的多了。 2)He is a man through and through.他是一个彻底的坏蛋。 3)You have been a blind, blind fool.你真是个十足的傻瓜.展开更多

The discharge capacity of the hydrogen-storing alloys are not only influenced by its thermodynamic property but also closely related to its dynamic property. When the temperature changes, the degrees of influence of the above-mentioned two factors on the discharge performance vary accordingly. As a consequence, adjusting compositions of the alloys to make them have good discharge performance under a relatively wide range of temperature is of great significance. On the basis of great deal of experimental investigation, the optimum combination of rare earth elements in hydrogen-storing electrode materials using at-30-55℃ is determined and the relationships between the cell parameters and discharge performance of alloys at -30℃ are discussed. Additionally, the DFEC calculation method has been improved to predict the discharge capacities, which is in good agreement with the experimental ones. This is of theoretical significance in investigating new hydrogen-storing alloys of the AB5 type.展开更多
