Random medium is closer to the actual medium, when the level of heterogeneous is greater than 5%, the reflection signal will be submerged in scatter noise.

随机介质与实际介质更接近，当不均匀程度大于5%或更大时，散射噪声将淹没矿体有效反射信号。

Using TFCC and correlation algorithms for processing of same practical vibroseis seismic data showed that the former could better suppress noises and detect weak reflection signal distinctively.

用TFCC算法和相关算法来处理相同的实际可控震源地震数据，显示前者能更好地压制噪声，并能清晰地检测到微弱回波信号。

The recent surge in older women at eating disorder clinics is not a reflection of failed treatment, experts say, but rather a signal that these disorders may crop up at any age.

专家认为，进来因进食障碍而就诊的中年女性的增多并不表示治疗无效，实际上，这表明，进食障碍在任何年龄都可能发生。

In the Madagascan data, for example, the choppiness of the waves in the open stretches of the Indian Ocean can be contrasted with the smooth reflection of the radar signal from the enclosed, calm waters of the Baie de Diego.
