求翻譯：傳出神經(jīng)元最初的放電頻率非常高當(dāng)重復(fù)快速刺激傳入神經(jīng)時(shí)，但放電頻率便逐漸減少經(jīng)若干毫秒或數(shù)秒鐘之后，這種就叫反射疲勞。反射疲勞發(fā)生在中樞的突觸部位。因此，反射疲勞實(shí)質(zhì)上就是突觸傳遞的疲勞。突觸疲勞的機(jī)制與突觸前末梢遞質(zhì)的耗竭有關(guān)。據(jù)估計(jì),如果神經(jīng)遞質(zhì)的來源得不到及時(shí)補(bǔ)充,則突觸前末梢所儲(chǔ)備的神經(jīng)遞質(zhì)僅夠進(jìn)行 1萬次突觸傳遞，其總量可耗竭在幾秒鐘內(nèi)。是什么意思？ 待解決

Efferent neurons of the initial discharge frequency is very high when the repeated rapid stimulation of afferent nerve discharge frequency will be gradually reduced by the number of milliseconds or a few seconds after, this is called reflection fatigue. The reflection fatigue occurred in central syn
