例句與造句

1. However, such fields have luminal signal velocity and do not allow superluminal communication.
2. In electronic circuits, signal velocity is one member of a group of five closely related parameters.
3. When the dispersion is anomalous, however, group velocity is no longer an indicator of signal velocity.
4. :The signal velocity is not faster than light in these situations even though it looks like it is.
5. Known as saltatory conduction, this type of signal propagation provides a favorable tradeoff of signal velocity and axon diameter.
6. It's difficult to find signal velocity in a sentence. 用signal velocity造句挺難的
7. In these boards, permeability is usually constant and dielectric constant often varies from location to location, causing variations in signal velocity.
8. Einstein resolved these problems by invoking a method of synchronizing clocks using the constant, finite speed of light as the maximum signal velocity.
9. In circuit boards made of FR-4 material, the signal velocity is typically about six inches ( 15 cm ) per nanosecond.
10. In most cases this is true, and the group velocity can be thought of as the " signal velocity " of the waveform.
11. In a uniform medium if the permeability is constant, then variation of the signal velocity will be dependent only on variation of the dielectric constant.
12. In circuit boards made of Polyimide material, the signal velocity is typically about 16.3 cm per nanosecond or 6.146 ps / mm.
13. Most slow light schemes can actually offer an arbitrarily long delay for a given device length ( length / delay = signal velocity ) at the expense of bandwidth.
14. Signal velocity is usually equal to group velocity ( the speed of a short " pulse " or of a wave-packet's middle or " envelope " ).
15. In a transmission line, signal velocity is the reciprocal of the square root of the capacitance-inductance product, where inductance and capacitance are typically expressed as per-unit length.
16. They came to the conclusion that in such cases the signal velocity is not equal to the group velocity, but to the front velocity which is never faster than the speed of light.
