| 1 | 汽车手动变速箱的齿轮敲击模拟和分析显示文摘本文阐述了汽车手动变速箱的扭振模型和分析 ,该模型是为齿轮敲击的分析和预测而开发的。它尽可能包容了动力传动系的许多部件去研究所有速度工况的敲击响应 ,模型包括的元件有发动机、离合器、飞轮、承载和非承载齿轮以及传动轴。适用于 MATLAB的数值方法用来解动力分析采用的差分方程。所得结果显示了模型和分析图解的有效性。已经开发了一个软件包可用于观察和分析任何动力传动系模型。本文介绍了采用该软件包分析 Daimler- Chrysler T3 5 0变速箱和其结果 ,它表明了齿轮敲击可能出现双侧、单侧和不规则碰撞三种主要的形式。敲击系数可用来比较不同齿轮副产生敲击的大小 ,它对于为最好地降低敲击声协调离合器是十分有益的。 | M.Y.Wang R.Manoj W.Zhao | 2002 | 传动技术2002，16，4： | 12 |

| 10 | Mesoporous Carbon-Tin Nanocomposites as Anode Materials for Li-ion Battery显示文摘A new mesoporous carbon-tin(MC-Sn)nanocomposite has been successfully prepared via a two-step method. From the transmission electron microscopy(TEM)observations,the tin nanoparticles were decorated on the as-prepared mesoporous carbons.The mesoprous structure of the carbon can effectively buffer the volume changes during the Li-Sn alloying and de-alloying cycles.The as-prepared MC/Sn nanocomposite electrodes exhibited extremely good cycling stability,with the specific capacity of Sn in the composite electrode calculated to be 959.7 mAh·g^(-1),which amounts to an impressive 96.9% of the theoretical value(990 mAh·g^(-1)).The reversible capacity after 200 cycles is 96.1% of the first cycle reversible capacity,i.e.,the capacity fade rate is only 0.0195% per cycle,which is even better than that of commercial graphite-based anodes. | Z.
