净化率 meaning in English
purification rate
purifying rate
Examples
- Air system can improve the conversion of hc and co . the project can ensure conversion rate of catalyst and reduce the decline of power of engine
这种方案既可以保证高的净化率，又可以使发动机的功率下降小。 - So the coating has effective anti - bacteria function and purifying function . in the analog normal house , we painted the indoor coating which can produce negative ion by activating rare - earth
对甲醛的净化率达到65 . 3 ，对氨气的净化率达到52 . 11 ，具有很好的净化能力。 - The temperature of exhaust gas can be increased after the upstream catalyst and the remaining exhaust can be reduced by the downstream catalyst . the motorcycle ' s emissions are high in hc and co , but low in oxygen
摩托车排气中hc和co的含量较高，氧气的含量较低，向排气管中补入二次空气，可以提高hc和co的净化率。 - The conclusion of test is that , with the new exhaust control muffler dynamical performance fuel economy and noise of the motorcycle have no obviously change . the conversion ratio of co hc and nox is more than 50 % with catalyst in muffler
试验结果表明，在加装了排气净化消声器后，对摩托车的动力经济性及噪声没有明显的影响，对co 、 hc 、 nox的净化率都在50以上。 - ( 9 ) by studying matching between catalytic converter and exhaust gas system , the conclusions having been gotten as follow : " purifying step by step and driving step by step " and " mental substrate and chinaware substrate being used in same engine " being the laying principles in exhaust gas system , which can solve the contradiction between high converting efficiency of exhaust emission and small loss of power , fuel economics , the rapid light - off and laying difficulty of catalyst
（ 9 ）进行了催化转化器与排气系统的匹配研究，对于催化剂的布置，提出了“分级净化，逐级推动”的原则；对于载体形式的选择，提出了“金属载体和陶瓷载体复合”使用的原则。这样可以良好的解诀催化转化器与发动机匹配时，排气污染物高净化率与动力性经济性损失小之间的矛盾、快速起燃和结构布置困难的矛盾。
