  2. 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。

  5. The porous diffusion type silencer is widely used to reduce the air flow noise because of its small volume and high noise attenuating ability. the out case of the silencer plays a very important role in reducing noise. the effect of the hole ' s shape, diameter and the distance between neighboring holes as well as the matchup between the case and the sound absorbing material tube are investigated experimentally. the relation between the out - flow noise and the gas velocity distribution is carefully studied for two different kinds of matchup between the case and the sound absorbing material tube. some useful results are gotten, which may be valuable to the design of the silencer

    多孔擴散型消聲器由於其體積小、消聲性能高而廣泛應用到排氣噪聲的降低上，其外殼對消聲器的消聲性能具有重要作用.本文對此類消聲器外殼的孔型、孔徑和孔距以及外殼同消聲材料的配合方面進行了細致的實驗研究，特別對外殼與消聲材料的配合與其排放噪聲以及外部流場之間的關系進行了探討，得到了一些有用的結論，對消聲器性能的提高具有一定指導意義。
