尽管软弱夹层对工程往往产生不良影响，但同时又对地震波具有阻隔作用。
The weak intercalations have an impedance action on seismic wave propagation in spite of its adverse influence on engineering body.
这样既通透又能起到阻隔作用，还非常隔音，厨房里的噪音外面根本听不见。
This will not only transparent but also play a blocking role, but also very sound, the kitchen can not hear the noise outside.
套管井中，由于套管对电流的强阻隔作用，只有极其微弱的电流可以进入地层，使得过套管电阻率测井很难实现。
Casing resistivity logging is hard to realize because of the strong hindering effect of casing to electrical current and only feeble current can enter the formation.
特别地，两种分子标记的结果都说明了琼州海峡（把海南岛和中国大陆隔开）对日本伏翼的基因流具有很大的阻隔作用。
Specifically, both markers indicate that the Qiongzhou Strait, which separates Hainan Island from the continent, acts as a significant barrier to gene flow.
