数控机床正在向精密、高速、复合、智能、环保的方向发展。精密和高速加工对传动及其控制提出了更高的要求，更高的动态特性和控制精度，更高的进给速度和加速度，更低的振动噪声和更小的磨损。问题的症结在传统的传动链从作为动力源的电动机到工作部件要通过齿轮、蜗轮副，皮带、丝杠副、联轴器、离合器等中间传动环节，在些环节中产生了较大的转动惯量、弹性变形、反向间隙、运动滞后、摩擦、振动、噪声及磨损。虽然在这些方面通过不断的改进使传动性能有所提高，但问题很难从根本上解决，于出现了“直接传动”的概念，即取消从电动机到工作部件之间的各种中间环节。随着电机及其驱动控制技术的发展，电主轴、直线电机、力矩电机的出现和技术的日益成熟，使主轴、直线和旋转坐标运动的“直接传动”概念变为现实，并日益显示其巨大的优越性。直线电机及其驱动控制技术在机床进给驱动上的应用，使机床的传动结构出现了重大变化，并使机床性能有了新的飞跃。

在文献[21]中，杨云等人研究了添加稀土对Zn-5%Al合金热镀锌的影响，结果显示：在Zn-5%Al合金中加入.1%～.2%的稀土，能降低合金镀液的表面张力，减小溶液与钢板的润湿角，增加溶液在钢板上的上升高度和吸附功，从而改善合金镀液与钢板间的润湿性，提高合金镀层的防护性能。文献[22]指出，微量稀土元素的加入降低了镀液熔点，提高了合金的流动性，改善了镀层的成型性，并在一定程度上降低了锌耗和能耗。

尽量不要把吸油烟机安装在门窗等空气对流较强的位置附近，以免影响吸油烟效果。出风管不宜太长，不要超过2米，而且尽量减少折弯，避免多个9度折弯，否则会影响吸油烟效果。为油烟机预留电源位置时注意不要与安装油烟机的打孔位置和装饰板位置发生重叠。止逆阀非常有用，即使需要额外付费也应该装上。止逆阀一定要堵住烟道开孔、否则一样会有油烟反逆。安装好止逆阀后必须确认开合良好后才能装入出风管。
