比起普通阀芯，具有耐磨性强、密封性好等功能，其防漏水性能也更好，建议能够选择陶瓷阀芯的龙头。此外，选购龙头时，还要亲手试试开关的开合是否顺畅，看看龙头表面的电镀层光滑与否，这些都是判断龙头好坏的关键因素。选购水槽：出水口的设计很重要目前多数厨房的水槽都是34不锈钢一体成形，盆体坚固耐用，基本不用担心使用寿命的问题。关键是水槽的下水装置，很多家庭习惯性洗菜、洗碗时，直接让残渣从水槽的下水口中流出，长期养成这一习惯容易导致下水口堵塞、水管漏水、下水道发臭等问题。

前面我们对步进电机与伺服电机之间的区别已经做了一些分析，也知道它们之间已经有六点不同的分析，其实步进电机与伺服电机在控制方式上同样也存在着区别，步进电机的控制方式是开环控制，而伺服电机采取的控制方式则是闭环控制。

那么为什么步进电机和伺服电机会在控制方式有区别呢？原因是：

步进电机：当步进电机开始真正工作时，步进驱动器会接收到一个脉冲信号，它就驱动步进电机所设定的方向进行转动到一个固定的角度。那么我们是可以通过控制脉冲的个数来进行控制角位的移量的，同时还可以通过对控制脉冲频率进行控制电机转动的速度和加速度，也因为这样才证实了步进电机的控制方式是：开环控制。
