测量动态早期斜坡、原发肿瘤、髁突、鼻甲的相对信号强度并作出动态曲线。
Relative intensity on early phase of DCE MRI and relative intensity-time curves of clivus, original nasopharyngeal tumor, condylar process, and nasal concha were measured.
这种交换标准是建立在绝对和相对信号强度基础上的，其性能指标即平均交换量和平均交换延迟。
The handoff criteria are based on absolute and relative signal strengths. The performance criteria are the average number of handoffs and the average handoff delay.
相对而言，它们不受多路径消除效应的影响，例如当返回的强反射波与直接路径信号不同相位时，降低了接收机中的信号强度。
They are relatively immune to multipath cancellation effects, such as when a strong reflected wave arrives out of phase with the direct path signal, reducing the signal strength in the receiver.
