查询词典 circuits

The unit's transmitter sends out pulses of ultrasonic waves at the same frequency as the bat, and the receiver picks up the returning echoes, Because these are still above the frequency at which the human ear can pick them up, the echoes are filtered through circuits which turn them int clearly audible 'bleeps' before passing them into headphones.

由于这些仍是在频率上超过了人耳的可闻范围，回波在送到耳机之前通过电路滤波，这个电路把回波转化为清晰可听的信号声。

This article presents a new technique to reduce the size of microwave planar circuits using defected ground structure.

前 言目前在广泛使用 MIC和 MMIC技术的微波平面电路设计中，小型化设计研究已经成为一门非常重要的课题。

These results suggest that in the central nervous system of small mammals, AP waveforms mature rapidly in many types of neurons, thus, coordinated activities in neuronal circuits may occur. In early postnatal development, GABA receptor mainly mediates an excitation effect, depolarizes P6 MGBv neurons and dramatically increases the frequency of AP firing. Inhibition of GABA receptor matures slowly along with increment of postnatal days.

结论大鼠MGBv神经元的AP波形成熟较快，可在中枢神经系统的神经元环路中产生协调性的活动；在MGBv神经元发育早期，GABA主要作为兴奋性神经递质而发挥作用，它可使P6的MGBv神经元产生去极化，AP发放频率显著增加，随着出生后日龄的增加，GABA受体的抑制作用才逐渐发育成熟。
