我们在有关针麻原理研究的某些实验中,需要对肌电或外周神经干的自发或诱发动作电位作量的比较。这在放电频率低的情况下是不难作到的,如单根神经纤维或神经纤维细束,以及运动单位型肌电图,只要简单地计算单位时间内锋电位的数日即可。但对多单位放电,放电频率较高,单靠肉眼判断就困难了,必须借助于仪器。常用的这类仪器是积分器,即藉电 In some experiments on the principle of acupuncture anesthesia, we need to compare the amount of spontaneous or evoked action potentials of myoelectric or peripheral nerve stems. This is not difficult to do with low discharge frequencies, such as single nerve fibers or nerve fiber bundles, and motor unit EMG, as long as a few days to simply calculate the front potential per unit time. However, the discharge of multiple units, the discharge rate is higher, it is difficult to judge by the naked eye, must rely on the instrument. Commonly used this type of instrument is an integrator, that is, by electricity
