bridge input circuit 桥式输入电路
The main function of a Data Binding class is to bridge data formats that correspond in some way to the schema of an input or output message.
数据绑定类的主要功能是桥接以某种方式与输入或输出消息的模式对应的数据格式。
L297 chip generates pulse phase sequence signals of which the pulse width is adjustable. The signals are the input ones of dual bridge driving circuit and drive the stepper motor after amplification.
L 297芯片产生脉宽可调的脉冲相序信号，该信号作为双极性桥式功率驱动电路的输入信号，放大后驱动步进电机。
Now the main method that gains the stress data is: technical persons measure the stress of the bridge regularly and then input it to the computer.
当前的应力数据采集主要采用的方法是：由专业技术人员定期到现场对桥梁应力进行测量，然后将获得的数据人工输入计算机。
