But because the extension of the rubber band is not directly proportional to the external force, the scale of the rubber band can not be divided equally.
但由于橡皮筋的伸长与所受外力不成正比，故不能等分地进行刻度。
In cases in which the process can be controlled within a band from the set point, proportional only controller are sufficient.
在一些场合，过程变量仅仅要求控制在设定值的周围，纯比例控制器就足够了。
The temperature controller is a true three-mode controller that, in addition to set point commands, also responds to programmable proportional band and maximum power Settings.
温度调解器是，除凝固点命令之外，也反应可编程序的成比例范围和最大值动力调整的一个真实的三方式控制器。
