延长使用期限。双色水位计双色水位计主要有透射式、反射式和反透式等数种。透射式双色水位计这种水位计由反光镜、光原、红、绿滤光镜、柱面聚镜、平面镜、影屏、框架、汽水旋塞等构件组成。透射式双色水位计的工作原理与其他形式的水位计基本相同，所不同的是光源的光线经反光镜反射，通过光学系统，使穿过水的那部分光线在影屏镜上呈绿色，而穿过汽的那部分光线在影屏镜上呈红色，从而在影屏镜上显示了代表水绿、汽红锅筒内水位的变化。反射式双色水位计反射式双色水位计是利用光在水和蒸汽中具有不同的折射率，通过棱镜的反射作用，使水位计中蒸汽部分呈红色．水部分呈绿色。反透式双色水位计它的结构介于透射式与反射式之间，其水位显示既利用了光线的透射。

可以调节升流器电流的调压器，及负载。[10]注意事项电流互感器-使用注意事项电流互感器[11]运行时，副边不允许开路。因为一旦开路，原边电流均成为励磁电流，使磁通和副边电压大大超过正常值而危及人身和设备。因此，电流互感器副边回路中不许接熔断器，也不允许在运行时未经旁路就拆下电流表、继电器等设备。电流互感器运行时，副边不允许开路。原因如下：⒈电流互感器一次被测电流磁势I1N1在铁芯产生磁通Φ1⒉电流互感器二次测量仪表电流磁势I2N2在铁芯产生磁通Φ2⒊电流互感器铁芯合磁通：Φ=Φ1+Φ2⒋因为Φ1.Φ2方向相反，大小相等，互相抵消，所以Φ=0⒌若二次开路，即I2=0，则：Φ=Φ1，电流互感器铁芯磁通很强。

同时由于起动转矩较大，将对负载产生冲击，增加传动部件的磨损和额外维护。所以当电机的容量较大（一般为超过电源容量的20%—30%时）均采用降压起动。传统上采用的降压起动的方法有Y/△换接起动和自耦变压器降压起动。虽然这两种起动方式均可降低起动电流，但是在降压起动过程完成后的分档投切和加全压的瞬间，仍将产生数倍额定电流的尖峰电流（二次冲击电流），此电流将对配电系统造成冲击，同时产生的破坏性的动态转矩会引起水泵电机的机械震动，对电机的转子、中间齿轮等非常有害，并使供电线路电耗增大。软启动器也是降压起动器的一种。它是利用性能先进的微处理器，合理有序地控制大功率晶闸管组件导通，使之产生逐步增加的平滑的交流电压加在交流电动机上。

如果利用系统论的观点，交互设计是从属于产品设计系统的子系统。设计原则编辑人机界面设计应该考虑以下原则。以用户为中心的基本设计原则在系统的设计过程中，设计人员要抓住用户的特征，发现用户的需求。在系统整个开发过程中要不断征求用户的意见，向用户咨询。系统的设计决策要结合用户的工作和应用环境，必须理解用户对系统的要求。的方法就是让真实的用户参与开发，这样开发人员就能正确地了解用户的需求和目标，系统就会更加成功。顺序原则即按照处理事件顺序、访问查看顺序（如由整体到单项，由大到小，由上层到下层等）与控制工艺流程等设计监控管理和人机对话主界面及其二级界面。功能原则即按照对象应用环境及场合具体使用功能要求。
