In addition, taking the single-pole and two-pole Debye model for example, the composite EM scattering from 1-D dispersive sea water and soil with and without a target are analyzed, and the results are also verified by those of the time-harmonic wave incidence. 5.

另外以单极和双极Debye模型为例，分析了一维色散海水、土壤及其与二维目标的复合电磁散射特性，并与时谐场源激励下的结果进行了验证。

Royal Dutch Shell yesterday defended deep-water oil drilling as it announced a near-doubling of its second-quarter profit and a beefed-up target for asset sales.

荷兰皇家壳牌（Royal Dutch Shell）昨日为深水石油钻采进行了辩护。与此同时，该公司宣布第二季度利润接近翻番，还提高了资产出售的目标。

Hitting a target the size of a salad plate through a mile of water and 2 ½ miles of rock may sound a prodigious feat, but modern drilling equipment makes it reasonably straightforward.

要穿过1英里深的海水及2.5英里厚的岩层，击中一个盘子大小的目标，听起来像是一件不可思议的伟绩，但现代钻井设备使其变得相当直接。
