前曾报道过一种肌力换能器,与其它换能器一样,是不带测量电路的。这种换能器要把离体心肌和子宫的收缩及肠管运动等肌张力的变化,显示在示波器屏上或描记在记录仪上,必须通过一个测量电路将机械收缩力转变成相应的电压讯号才能实现。而装制一个测量电路,既费时耗物,又使用 A muscle force transducer has been reported before, as with other transducers, without a measurement circuit. This transducer to the isolated myocardium and uterine contraction and bowel movement and other changes in muscle tone, displayed on the oscilloscope screen or recorded in the recorder, must measure the circuit through a mechanical contraction force into a corresponding voltage signal To achieve. The installation of a measuring circuit, both time-consuming supplies, but also use
