前为两者一个电阻太小，一个电阻太大，通过二极管的电流太大，易损坏二极管，后者则因为内部电压较高，容易击穿耐压较低的二极管。如果测出的电阻只有几百欧到几千欧（正向电阻），则应把红，黑表笔对换一下再测，如果这时没测出的电阻值应是几百千欧（反向电阻），说明这只二极管可以使用。当测量正向电阻值时，红表笔所测的那一头是二极管的负极，而黑表笔所测的一头是该二极管的正极~（二极管的单向导电特性）。通过测量正反向电阻值，可以检查二极管的好坏，一般要求反向电阻比正向电阻在几百倍。

通过改变相电流的通断时间实现细分的方法通常被称为“电流时间混合法”，其具体实现方式如下：

在常规的步进电机驱动电路中，每当时钟脉冲到来时，电机的线圈便会被分配电流以使电机旋转一步。如果我们在每个时钟脉冲到来时，依次给A、B、C三相通电，电机就会正常旋转。但如果我们改变通电的顺序，例如先给B相通电，然后给C相通电，再给A相通电，这样电机就会先转过一个角度，然后在此基础上再转过一个角度，这就是通过改变通电时间的顺序来实现细分的。

这种方法的优点是简单易行，但是细分后各相电流会发生变化，需要控制各相电流的大小，才能达到好的细分效果。因此，对于需要控制的场合，可以考虑使用这种方法进行细分。

另外，这种方法还有一个优点是，由于通电时间顺序的变化是通过控制逻辑电路来实现的，因此可以实现细分倍数的柔性控制。也就是说，我们可以根据需要随时改变细分的倍数，而不需要更改硬件电路。

总的来说，通过改变相电流的通断时间实现细分的方法需要控制各相电流的大小和通断时间顺序，才能达到好的细分效果。但在一些需要高精度控制的场合，这种方法具有很好的应用前景。

许多物质都具有一定的颜色。：高锰酸钾溶液呈紫红色，硫酸铜溶液呈蓝色等等。也有许多本身不具备颜色，但加入适当试剂后能生成有特征颜色的化合物，如锰元素的测定，假如-银溶液溶解后是淡黄色，接近无色，加入过硫酸铵后与溶液中锰元素反应生成红色的化合物，当锰元素在溶液改变时，溶液颜色也随之改变，锰元素越高颜色越深，反之颜色越浅。钢铁元素分析仪采用比色法对某种元素进行颜色对比，比色法是基于测量溶液中物质对光的选择性吸收程度而建立起来的分析方法，目前广泛用于机械工业理化试验室中。
