With improved BP network, Adopting deep, short resistivity, and acoustic logging, the model to recognize oil layer and water flooded layer is established.
利用改进的BP算法，采用深、浅侧向电阻率、声波时差测井建立了油层、水淹层的识别模型。
The main results indicate that in boundary layer the stable layers observed by acoustic radar echos correspond fairly to synoptic systems.
结果表明：声雷达回波所反映的稳定层和天气系统之间有较好的对应。
The rhythmic beauty of languages is made up of acoustic beauty in phonetic layer, image beauty in imagery layer and beauty of emotional movement in semantic layer.
语言的节奏美由语音层的音响美、意象层的画面美、语意层的情感运动美构成。
